Cosmetic Dentistry Adelaide - Crowns and Veneers
Veneers are placed on the visible front part of the tooth.
- The tooth is prepared by shaving off a minimal amount of tooth, in some cases nothing at all, and porcelain or composite bonded in place.
- Porcelain veneers are aesthetically superior to composite and require less maintenance long term.
- Porcelain veneers are constructed in a laboratory on a model and require 2 visits.
- Composite veneers are done chair side are slightly cheaper not as durable as porcelain and need to be repolished on a regular basis to maintain lustre.
Crowns cover all surfaces of a tooth.
Crowns are all constructed in a Laboratory. Chair side constructed crowns are not used at DrZielinski & assoc as we feel that these are aesthetically inferior and not as well fitting as we like. There is much advertising and marketing in relation to these Cad Cam machine made chairside crowns and restorations but the real science tells a different picture.
Crowns are placed on a tooth which is structurally compromised.Such teeth are heavily filled ones which are over ½ in filling material and in particular endodontically treated teeth which are dry and brittle on top of that.
- Crowns can be made of gold, porcelain fused to gold, zirconium layered with porcelain or purely porcelain.
- On posterior teeth, gold is best when it comes to function and longevity however aesthetically porcelain is superior.
- Inlays/Onlays are an indirect restoration and cover less tooth than a full crown.For simplicity these may be referred to as ½ or ¾ crowns
In some cases a full crown is not warranted and a more conservative yet durable approach is needed. This is where the tooth is prepared for an inlay or onlay, an impression taken and the final restoration bonded in on a subsequent visit.
