ABSTRACT:
Title: A study on standards of teeth preparations for anterior resin bonded all-ceramic crowns in private dental practice in India. Aim: To analyse the standards of teeth preparations for anterior resin bonded all-ceramic crowns in private dental practice in India. Objective: To evaluate the standards of teeth preparations for anterior resin bonded all-ceramic crowns in private dental practice in India. Background: Tooth preparation is one of the important aspects of restorative dentistry because it establishes the foundation for whatever restoration is being placed5. Unfortunately, training in dental schools relative to tooth preparation is too often oriented to the dimensions of rotary instruments rather than tooth morphology6. 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 esthetics7. these two are governed by finish line. Hence a proper, specific finish line has to be chosen for different types of crowns. Reason: A dentist must be aware of different types of finish lines and the most preferred ones for each type of restorative material used. This is important because the occlusal forces vary in different regions of the oral cavity ,for eg: the mastication load is more on the posteriors than on the anteriors. Hence preparing a suitable finish line for a specific restorative material can increase the retention of the restorative material and therefore this research was being conducted.
