Replacing Old Mismatched Crowns and Veneers to improve the aesthetics
This patient presented to me to complain that she did not like the look of her veneers and one of the lower veneers had moved out of its place. After a thorough clinical exam, I realized that the patient didn’t have four veneers on the upper arch but two porcelain veneers and two crowns. I explained to her the difference in materials used to fabricate the crowns and veneers is the reason they don’t look the same. Optical properties of different porcelain are vastly different and mix and matching them is not a good idea.
She asked me to do whatever was necessary to match the shape and shade of her veneers to idealize her aesthetics. I replaced the Old Mismatched Crowns and Veneers with a new set of four all ceramic crowns in the upper jaw and a set of three veneers & a single crown on the lower jaw to idealize the shade, shape and arrangement of the teeth. All the restorations were similar except the one crown on the implant in the lower arch, but it was characterized with various modifiers to match the shade of adjacent veneers.
Replacing Old mismatched crowns with Life-Like all ceramic crowns
Treating dentists is not an easy task. As a prosthodontist I was up to the challenge and felt privileged to be asked by my colleague to address his cosmetic concerns. Guiding the master ceramist to characterize the shade, shape and internal characteristics is something a prosthodontist can achieve for you to idealize your smile and bring back the lost confidence to smile.
This patient was previously treated to receive a single crown, where two cracks were found in his tooth. I recommended to my patient a more conservative approach than their previous treatment plan to cover the cracked part with an Onlay instead of a crown. I presented two excellent options for the onlay, gold or ceramic. To achieve maximum esthetics, the ceramic option was chosen as a material of choice.
An Onlay replaces only the part of the tooth that is missing and is similar to a “partial crown“, unlike a crown that completely covers the tooth. Onlay is a more conservative approach and significantly kinder to the gum (gingiva) when designed properly.
Porcelain Onlay to restore a molar with a chipped silver filling
Knowledge regarding tooth preparation design, “resistance & retention forms” is the most important element when recommending this type of restorations, otherwise early failure is inevitable (usually in a form of Onlay keeps coming off). There are many different ceramics used in dentistry. Each ceramic behaves differently and has a unique characteristic. The longevity of a restoration depends of careful choice of ceramic material, beside other factors.
Single Crown Replacement
PFM crown #30. A Metal Island on top of the crown indicates inadequate tooth preparation & poor design (left photo). The crown was replaced with an all ceramic crown due to an open margin and tooth sensitivity that did not go away for several months. Metal showing under the porcelain is usually a poor sign and shows a crown done improperly.
We replaced the inadequate crown with a natural-looking single crown that matched the shape and shade of the surrounding teeth. (right photo)
Porcelain Fused to Metal Crowns and Bridges in Smile Makeover
This middle aged female was frustrated with her front teeth and the way she had to cover her lips before smiling. A long term ailing dental implant, which was left unattended, had caused significant bone loss and a large defect. The bony defect could not be rebuilt after two regenerative surgeries (at another dental office). Finally she was referred to me for a none surgical prosthetic solution. I never forget how she hugged me in tears for several minutes when her case was completed. She is still doing fine without any complications after nearly 10 years.
All Ceramic Crowns for the upper incisors.
This retired University professor was interested in treatment by a Prosthodontist, so she found me after her previous dentist dropped her dental insurance. She was initially interested in getting two veneers, however after a thorough clinical evaluation, I recommended two crowns to improve the esthetics and provide adequate longevity for my treatment plan. This decision was based on ideal treatment to provide predictable longevity. Veneers are conservative restorations for ideal situations, but when the tooth has a large restoration, veneers won’t last as long as crowns.
One of my sweetest patients, she used to be a photo model in her teens and twenties. Due to age, loss of back teeth, bite collapse, wear of the remaining teeth, her smile and tooth function had deteriorated. Her main concern was to be able to chew better and to show more teeth the way she used to.
We provided a full mouth smile makeover, with a few visits for fine tuning her bite with T-Scan (dental occlusal analysis system). Her “After” smile is one of complete satisfaction.
There are many factors that would affect the longevity of restorations. In recent years there have been many advances in dental materials, especially dental ceramics. Porcelain restorations for the most part all look the same to the eyes of a lay person but ceramics behave differently in the mouth. Proper choice of ceramics (porcelain) for each case is one of the important factors that influence not only the esthetics but long term success of that restoration.
Onlays are conservative tooth restorations which can be made from porcelain or gold alloys. The most important characteristic of “Onlay” restorations is the conservative nature of its preparation. Onlays usually last for several years, but do have a drawback, as they are harder to prepare, and will fail quickly if not designed properly. Tooth Preparation for Onlay requires Skills of an artist and knowledge of an engineer.
Selection of proper material for its fabrication for a given case is also critical for its success, which our office excels in.
Cast Gold Onlay I
In this case the old amalgam filling along with part of the tooth fractured off below the gum level. Instead of crown build up and a crown( which would have been more costly for the patient), fabrication of a Gold Onlay was recommended. Porcelain is not a material of choice in this case.
Ceramic (Porcelain) Onlay
In this case, the molar was restored with a porcelain onlay and the bicuspid with a full all ceramic crown.
Deep & Subgingival Caries and Gold Inlay
This tooth had recurrent decay under an existing composite filling. After conservative tooth preparation a cast gold inlay was fabricated to restore the tooth properly. With good oral hygiene these restorations last for a couple of decades.
Short Tooth, an Indication for an Onlay
It wouldn’t have been an ideal treatment to restore this tooth with a full crown, unless I’d done crown lengthening. For this reason an Onlay was fabricated out of high impact lab processed composite. It was bonded to the tooth. Also grooves were included to prevent dislodgement.
Cast Gold Onlay #19
This molar needed a full coverage after root canal treatment to protect it from getting fractured. In order to prevent crown lengthening, an “Onlay” was fabricated instead of a crown. Onlays don’t have to be gold all the time, but in this case a cast gold onlay was more preferable than a porcelain Onlay.
Cast Gold Crown
This tooth was treated endodontically (root canal) and patient was referred to me for the restorative part.
In order to prevent crown lengthening, a “cast gold onlay” was recommended. Complex geometry and tooth preparation for this type of restorations, makes its fabrication and seating more difficult. This is one of the reasons it is best completed by a Prosthodontist.
Poor Tooth Preparation #30
This patient was complaining that the crown kept coming off frequently. Lack of adequate “resistance form” was the main reason and a new tooth preparation & crown fabrication was recommended. Compare the image on the left with the one on the right side.
Cast Post & Core
Cast Post and Core
Complete loss of clinical crown due to long lasting caries was compensated with a “Cast Post and Core”. After cementing the cast post and core, an impression was made to fabricate a crown.
All Ceramic Crown & Veneers for the Lower Front Teeth
Improving the aesthetics and function in this case was one of the reasons to restore 4 front teeth with life like all ceramic restorations.
Full mouth rehabilitation – Case 1
Restoring the entire dentition is referred to as “Full mouth reconstruction or rehabilitation” and it requires extensive postgraduate training and knowledge regarding TMJ, occlusion, dental materials, and sound principles of fixed prosthodontics. Prosthodontists’ extensive education and training, as well as ongoing continuing education , are more than capable of treating such case with the utmost confidence and predictable outcome.
This retired female patient said she had neglected her teeth for years, but finally decided to take care of herself. This case was treatment planned for splint therapy and TMJs evaluation, selective extractions, multiple implant placement (Nobel Biocare), Atlantis custom abutments, followed by full mouth rehabilitation.
Most phases of the treatment including all the laboratory steps were performed by Dr. Noohi.
Full mouth rehabilitation – Case 2
The slides below present a female patient who came to me with chief complaint that, “Doctor! I used to show a lot of my teeth, but for the past few years I show less and less teeth. I think my bite is changing”.
After a clinical evaluation it was evident that loosing her back teeth had caused her bite to collapse. Bite collapse causes over-closing and significant wear, excessive shortening of teeth, migration of teeth and occasionally periodontal disease. Restoring her entire dentition to compensate for the loss of vertical dimension of occlusion (Bite) was recommended to her.
At that time she was not ready to have a couple of dental implants to replace her lost lower molars but she was motivated to do that in the future.
Chipping of the front teeth.
This case is about a young girl who was referred to me after trauma to her front teeth. She fell with her face down and broke her front teeth 5 days before her birthday. She was referred to me to as an emergency, and i stayed after hours to do whatever was necessary to take care of her. The young girl was very embarrassed to smile and did not want to appear with a broken tooth on her birthday. She was confident she could cover her lip laceration with make up but could not do anything about her front teeth. My goal was to make her ready for her birthday and improve the aesthetics short term and provide her long lasting restoration for the future.
Patient had a diastema (Space) between her front teeth and asked me to keep it. I used e-max press combined with layering technique to mimic her natural teeth. Characterization of the surface was done by a talented Ceramist to provided the same surface texture and white spots to blend them with the rest of her teeth.
Not all “porcelains or ceramics” are the same. They have different characteristics and their application varies from case to case. Their strength, optical characteristics (translucency, transparency), etc. are vastly different. Using one type of porcelain for all cases is most certainly compromising the goal of the treatment. Prosthodontists in contrast to most general dentists are the decision makers when it comes to choose what type of material to use rather than leave it to the laboratory technician to choose what they consider best which is a more common practice. Mixing different materials, will cause optical mismatch with ultimately leads to patients dissatisfaction in some cases and in other material failure.
Tooth preparation for a veneer can be challenging and may lead to early failure if it is not filed properly. Over filing the teeth for veneer is not an uncommon complication and can lead to a lot of frustration for patients.
Application of different types of porcelain requires vast knowledge about dental ceramics. If you think your health matters, go to a professional in the restorative field. Find a prosthodontist today to discuss what is best for you.
Porcelain veneers after orthodontic treatment
The case below is about a gentleman who had orthodontic treatment as an adult to align his teeth, but after 2 years being in braces the two lateral incisors could not be moved. They were diagnosed as being ankylosed, which means being fused to the jaw bone. The over outcome of the orthodontic treatment was good, but the patient was not satisfied with the rotated lateral incisors. After giving it a lot of thought, he decided to have the front teeth veneered to idealized the outcome. It was one of those cases that he really pushing for the excellence to maximize the cosmetic appearance, even though the initial impression of his teeth was fairly acceptable in my view. However, as they say beauty is in the eye of the beholder.
Initial exam of the patient and meticulous attention to details in collecting relevant data such as, evaluating the smile, taking notes of what needs to be changed, gum exposure teeth shape, shade, texture, facial form, uneven features, fullness of the lips, etc. Photography with professional camera and ring flash, instead of a cell phone, under different lightening will help tremendously to capture valuable information to communicate with the master ceramist when it comes to idealize the smile. Some people like natural looking teeth, and others like fashion model. Shaping teeth for a powerful masculine personality vastly differs from a soft and more feminine personality. Also, the shape and shade of the front teeth can be as such to express a young age or an aging dentition. That could be a reason why some people choose to go to a prosthodontist to achieve the highest level of care and some other choose a general dentist just to replace their missing teeth.
Getting back to our case. I started the work with a wax up mock up and before touching his teeth, i gave him the chance to visualize what i was going to do and after his approval a tooth preparation guide was used to file down VERY CONSERVATIVELY in such a way that most tooth surface was still covered with enamel to maximize the bonding and longevity of the restorations. Failing to keep enamel on the surface of the prepped teeth means early failure and de-bonding of the restorations.
a set of 7 super thin veneers were fabricated by a master ceramist and they were bonded meticulously one at a time. it almost took me 2.5 hours to bond 7 veneers and check the occlusion.
Smile Makeover with Porcelain Veneers
Ms. V. came to my office to discuss her smile. She told me that, ” I had never been happy with my veneers”.
After a couple of visits to get to know the patient and collecting adequate information about Ms. V. and a thorough discussion with the patient, it was decided that the shape, proportion, and shades of the teeth need to be modified in order to make them look ideal and customize to what patient desired. I was redoing someone else’s work so I was under pressure to assure my patient that I would deliver exactly what she wanted.
Patient went through a provisional stage for a few weeks when the esthetics were evaluated and occlusion was tested & adjusted to achieve a stable bite. I duplicated the provisional veneers and crowns and transferred them to my master ceramist technician with a detail description about the shade, shape, size and how the veneers should be fabricated.
The end result is the product of several hours of planning & re-evaluating before executing the process.
The patient was ecstatic with the result.
Prosthetic reconstruction of congenital alveolar defect
This retired patient presented to my office with a simple request, “Doctor! I don’t want you to make me look like a movie star. But I want you to improve my teeth.” Despite the fact that there were several issues (Oro-nasal communication, congenital upper jaw defect, past history of oral reparative surgery, multiple partials and bridges, etc) to address, the treatment plan was designed to address mainly his chief complaints without any compromise in treatment outcome.
Most dentists would like to treat their patients comprehensively and ideally. However, the reality is that not all patients desire to have an ideal treatment or may have financial concerns that prevent them from pursuing an extensive treatment. It is important to recognize this fact and be able to formulate a treatment plan to address most important concerns without sacrificing the quality or longevity of the treatment.
These are before and after cases of patients with conventional or implant supported complete dentures.
Conventional Complete Denture & Hybrid Implant Supported Complete Denture
As a result of poor denture fabrication, poor occlusion design, long standing negligence, patient had developed what is called, “Kelly’s Syndrome”. This is a challenging condition in dentistry that requires significant knowledge in prosthodontics, experience along with advanced educations and surgical skills.
Upper and Lower Implant supported Over-Dentures supported by different types of dental implants.
(Sub-periosteal and root form implants connected with a bar and ball attachments).
This 84 year old patient had not had any maintenance treatments since her dental implants were placed and restored nearly 30 years ago. The lower over-denture was lost 4-5 years ago and was never replaced. The upper over-denture was significantly worn down leaving holes in the denture. The gum tissue was diseased ( inflamed and bleeding), dental implants were mostly exposed through thin recesses oral tissue. She had been rejected by some dentists to treat her due to complexity of her case on the one hand and significant cost of comprehensive treatment on the other. After Talking to patient a couple of times to discuss the treatment plan, a middle ground was fount to treat the patient with minimal compromise in treatment, keeping the cost down and improve the function and aesthetics (which was her main concerns).
Patient conditioned was stabilized and a new set of over-dentures were fabricated to improve her cosmetic and functional concerns.
Conventional upper Complete Denture and lower Teeth Supported Over-Denture
This patients came to see me to improve the condition of her failing bridge and denture and requested for an option other than dental implants. The decayed teeth in the lower arch under an existing bridge were retained, shortened and covered with Gold Copings to protect them from caries. Then two attachments were connected to two teeth to help retain the lower over-denture ( prevent movements during chewing). This procedure would replace the need for dental implants and save patient money and implant surgery.
Attention to details to rearrange the teeth in ideal position to follow her lower lip curvature significantly improve the appearance of the denture and gave the patient a life like teeth unlike the fake teeth arrangement of her old denture.
Conventional lower Complete Denture and Upper Implant Supported Over-Denture
Patient came to see me to repair her “old” broken lower denture. The denture was not thick enough to be strong enough. I recommended her to let me make a new set of dentures and i had a metal reinforcement built inside the denture to prevent future fractures. Arrangement of denture teeth were also idealized to improve the aesthetics.
What is an immediate denture?
An immediate denture is “a removable complete or partial denture fabricated for placement immediately after the removal of natural teeth.”
Same Day or Immediate Complete Denture: Case I
This female patient came to me to replace her crown on a front tooth which kept coming off. “I’ve never had dentures before and I am afraid of dentists”, she told me. She stated that she used to go to a dentist only for emergencies.
Instead of re-cementing her poor-fitting crown, I recommended a more definitive solution to improve her aesthetics and provide function for better chewing. After gaining her trust, we started the treatment plan to get an over-denture retained by “Locator” attachments. Instead of extracting her teeth and giving her a complete denture, i kept the roots and used them as anchors to support and retain her denture so it won’t move during function ( that is why it is called Over-denture in contrast to conventional denture).
Treatment with the over-denture resulted in an extremely happy patient and a new addition to our dental family.
Having a good planning strategy and extensive knowledge on how to execute each step allowed us to create predictable and positive outcome for the patient and save her several thousands of dollars for dental implants supported over-dentures.
Same Day or Immediate Complete Denture: Case II
John had multiple broken teeth which were not restorable and it was determined to replace them with an immediate complete denture and if he decided to convert it into an implant supported over-denture.
One of his teeth in the front of his mouth which had a root canal was retained to be used as an anchor to provide more retention. This was done by screwing an Attachment to the root of the tooth. It is a similar concept when a dental implant is used except that in this case it is connected to a tooth and not to a dental implant.
Same Day or Immediate Complete Denture: Case III
Periodontally compromised teeth in the lower arch were not salvageable and were planned for full extractions. An immediate complete denture was fabricated and relined with soft reline right after extraction all the lower teeth. Occlusion was checked and pt left with confidence that her lower denture is stable during function.
Conventional Complete Denture and Implant Supported Over-Denture
This patient was referred to me for fabrication of a new set of dentures. Her existing dentures were not ideal and her complaint was that it was moving too much. Her general dentist had relined it several times but it was not better. Finally she decided to see a Prosthodontist.
As the first step, her dentures were re-based to provide adequate stability and she was recommended to get two implants in the lower jaw along with a new set of dentures. In this case she received two Nobel Biocare dental implants and two attachments to retain the denture. The improvement was like “the difference between day and night”, as the patient stated. All the clinical and Laboratory steps were completed by Dr. Noohi.
Costs for dental care vary widely and should always be compared based on the quality, comfort, function and esthetics of care.
Specialists do not charge you because they hold a specialty certificate, but because you are holding a higher standard of care. If you think your health is worth it, then go to a pro; see if a Prosthodontist could help you.
Obturator after total maxillectomy
An OBTURATOR is a maxillofacial prosthesis that replaces part or all of the upper jaw and associated teeth lost due to surgery or trauma. I treated the patient after partial maxillectomy (due to oral cancer), with an obturator. However due to metastasis after a several months, she went through another Oral surgery for complete removal of her upper jaw (maxillectomy). I had to replace the old one with a definitive obturator to correct the facial compromise and enable patient to eat and drink. Definitive obturator is usally made after multiple relines and modifications of an interim obturator to make sure additional corrections wouldn’t be necessary.
In the first photo you can see facial asymetry (canting nose and lips on the left side) caused by inadequency in support of the lip.
This treatment requires knowledge and training in maxillofacial prosthodontics and is only rendered by specialists due to complexity of treatment and special tools and equipments needed.
All the clinical and laboratory steps of this case were completed by Dr. Noohi, and the case was presented at the University of Maryland School of Dental Surgery, alumni annual meeting in 2008.
Prosthetic reconstruction of congenital alveolar defect
Helping children and young adults with congenitally missing teeth or malformations is so rewarding I cannot put words to it. The smile and gesture of satisfaction that you see in their faces at the end of the treatment is priceless. There are times when the missing teeth, malformed or impacted teeth due to congenital malformations can be corrected by variety of prosthodontic treatment. It is crucial to emphasize the importance of consulting with a specialist who has a broader knowledge and skills to take over this type of cases.
E. was young teenager with congenitally missing multiple teeth. The first photo presents her smile prior to treatment. Orthodontic treatment to move her teeth into arch and align them properly was not successful after two years. Most of the teeth were fused to her jaw bone which prevented them to move. She was referred to a prosthodontist to restore the case with prosthetics to improve the aesthetics and restore function so patient can eat normally. The extend of acrylic under her upper lip improve the inversion of her lip by replacing jaw bone and providing lip support. The outcome of her treatment was a happy patient with a beautiful smile.
