Biologic Shaping in Periodontal Therapy
- 768 Downloads
Periodontal surgery involves modification of hard and/or soft tissues to achieve a therapeutic goal. These goals include treatment of periodontal defects, including furcation involvement of molars, and crown lengthening procedures to facilitate restoration of a tooth or teeth. Traditionally, resective and regenerative techniques focus on osseous structures with little attention given to modification of tooth surface. Unfortunately, this could lead to excessive removal of the bone and/or creation of an environment that is not cleansable and biologically incompatible. Further, regenerative techniques can yield unpredictable results in furcation lesions thus predisposing molars to further attachment loss. Biologic shaping is intended to create a cleansable, biologically compatible root surface that is manageable by both patients and dentists/hygienists. Here modification of tooth surface is the primary focus with removal of the bone performed only when absolutely necessary to create a biocompatible environment. This chapter will focus on biologic shaping during the course of periodontal therapy.
