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.
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.
