Abstract: BACKGROUND: Tooth preparation is one of the important aspects of restorative dentistry because it establishes the foundation for whatever restoration is being placed. Unfortunately, training in dental schools relative to tooth preparation is too often oriented to the dimensions of rotary instruments rather than tooth morphology. Understanding of tooth morphology is essential for developing preparations that will permit the restorations placed upon them to be functionally durable, provide optimal esthetics, and be biologically compatible with the periodontal tissues. The most important aspect of tooth preparation is retention of the crown and esthetics. These two are governed by finish line. Hence a proper, specific finish line has to be chosen for different types of crowns. AIM: To analyse and evaluate the standards of teeth preparations for anterior resin bonded all-ceramic crowns in private dental practice in India. MATERIALS AND METHOD: A cross sectional study was done in south indian population where 50 laboratory casts with tooth preparations for all ceramic crowns for anterior teeth were obtained from different general dental practitioners. Data obtained were statistically analysed. RESULTS: The study revealed that 70% of the dentists preferred a supra gingival margin for the tooth preparation. Majority preferred radial shoulder finish line over other types but a handful of them had no clear type of finish line being prepared with a depth in the range of 0.5mm to 1.5mm and uniformity was being observed in 84% of the cases. An axial convergence of 6 - 10 degree was prepared by 56% of the dentists. CONCLUSION: Preparation for resin bonded all ceramic crowns of the Indian clinicians work investigated were varied widely. Most of the clinicians follow proper tooth preparation principles while a handful of clinicians followed no specific principles. Hence, proper tooth preparation principles must be followed to ensure effective treatment in terms of esthetics and retention.
