Biologic Width - Knowledge Key for Restorative Dentistry: A Review

Aim: To elaborate the importance of the concept of biologic width in terms of restorative dentistry. Background: Biological width is the natural distance (combine heights) between the base of the healthy gingival sulcus or epithelial attachment to the tooth and the height of the alveolar bone or connective tissue. For better description of relationship between the periodontal tissues and conservative procedures is to restore form, function, esthetics, and comfort for the dentition. Most of the dentists are aware of biological width, its maintenance and its importance during application of crown lengthening. However, this review will elaborate on its importance in restorative dentistry. This article reviews the anatomy, categories, evaluation, violation, methods to correct the violation of biologic width and its relationship to periodontal health and restorative dentistry. Review Results: Respecting the biologic width and designing restorations accordingly is crucial. Biologic Width is the dimension of space that the healthy gingival tissues occupy above the alveolar bone. Incorrectly placed margins of restorations are a common cause of biologic width violation. This can lead to gingival inflammation and bone loss, thereby damaging the periodontal health as well as reducing the life of the restoration
