LAP Lambert Academic Publishing Dentists frequently balance periodontal, restorative, and esthetic concerns that provide an adequate tooth length, ensure periodontal health, and provide biological predictability. It is important that an artificial crown fits the prepared tooth accurately, as marginal deficiencies are predisposed to plaque accumulation and lead to increased risk of periodontal diseases. The successful integration of periodontal and restorative dentistry for teeth requires knowledge and application of both mechanical and biological principles.One critical factor associated with periodontal health, and the longevity of restorations is the precision of the margins at the periodontal-restorative interface.This book investigates the effects of the margins of fixed prosthesis on the periodontal health of the restored teeth.
