Is the rush to all-ceramic crowns justified?

Journal of the American Dental Association (1939)·2014

Dentists are increasingly overcutting teeth during restoration preparation, leading to unnecessary tooth structure removal. This trend, driven by factors like aesthetic goals and material choices, necessitates a re-evaluation of preparation techniques.

Area of Science:

  • Dentistry
  • Restorative Dentistry
  • Dental Materials

Background:

  • A trend towards overcutting teeth during preparation for dental restorations is observed in current literature and continuing education.
  • This over-preparation may stem from a desire for enhanced aesthetics, the use of all-ceramic or polymer crowns, and a preference for full crowns over conservative options like onlays or inlays.

Purpose of the Study:

  • To highlight the prevalent trend of overcutting tooth structure in dental restorative procedures.
  • To identify contributing factors and potential consequences of excessive tooth preparation.

Main Methods:

  • Review of current dental literature and continuing education trends.
  • Analysis of reasons cited for increased tooth preparation depth and scope.

Main Results:

  • Overcutting is frequently promoted, often linked to aesthetic considerations and the selection of specific restorative materials (e.g., all-ceramic crowns).
  • There is a notable shift towards preparing teeth for full crowns, even when less invasive restorations like onlays or inlays would suffice.
  • High-speed handpieces and large burs can inadvertently lead to excessive tooth structure removal.

Conclusions:

  • The current dental practice exhibits a concerning trend of overpreparing teeth, resulting in unnecessary loss of tooth structure.
  • Re-evaluation of preparation guidelines and conservative treatment planning is crucial to mitigate this trend.
  • Emphasis should be placed on appropriate material selection and preparation techniques to preserve tooth structure.
