Veneer or all-ceramic crown: the key is how much healthy enamel remains｜證據鏈
An all-ceramic veneer mainly covers the visible surface of a front tooth, whereas an all-ceramic crown surrounds more of the clinical crown. The choice is not simply between two materials according to aesthetic wishes. What changes the decision is how much healthy enamel and dentine remains, how much of the tooth consists of old restorations, whether there is a crack or previous root canal treatment, and whether the planned restoration can achieve bonding, support and cleanability after reasonable preparation. Clinical systematic reviews indicate that veneers bonded to enamel have better survival and success than those on substrates with severe dentine exposure or existing composite restorations, but this is not a boundary that can be applied by percentage alone. A laboratory review also supports the importance of preserving enamel, but cannot directly predict outcomes after years in the mouth. If ample healthy enamel remains, clinicians should first assess whether a localised design can achieve the aim. If the tooth is already extensively damaged, they must still determine whether a full crown offers a more rational overall restoration.

We have retrieved the full erratum and compared it line by line: after excluding one outlier study it revises the survival estimate for zirconia single crowns, and corrects one table classification (the authors state explicitly that this table error does not change the results of the study). None of the figures or conclusions cited on this card fall within the scope of the correction; the conclusion that zirconia should not be a primary option because of its high incidence of technical problems is unchanged.

FAQ
- Is a veneer necessarily more conservative because it is thinner?
- Not necessarily. Conservatism depends on how much healthy tooth tissue is actually removed, the margin position and restoration extent. If extensive preparation is needed to mask colour or change position, a restoration called a veneer may still lose the ideal advantage of enamel bonding. [F1]
- ベニアは薄いので、必ず低侵襲ですか？ — 必ずしもそうではありません。低侵襲性は、実際に除去する健康な歯質、辺縁位置、修復範囲によります。遮色や位置変更のため大きく形成すれば、名称がベニアでも理想的なエナメル質接着の利点を失う場合があります。[F1]
