Excerpt: A palatal view of a maxillary premolar during a crown lengthening procedure. Crown lengthening is a surgical procedure performed by a dentist to expose a greater amount of tooth structure for the purpose of subsequently restoring the tooth prosthetically . This is done by incising the gingival tissue around a tooth and, after temporarily displacing the soft tissue, predictably removing a given height of alveolar bone from the circumference of the tooth or teeth being operated on. While many general dentists perform this procedure, they frequently refer such cases to periodontists . Biomechanical considerations Biologic width The gingival sulcus (G) is a little crevice that lies between the enamel of the tooth crown (A) and the sulcular epithelium . At the base of this crevice lies the junctional epithelium , which adheres via hemidesmosomes to the surface of the tooth, and from the base of the crevice to the height of the alveolar bone (C) is approximately 2 mm, known as the biologic width . Biologic width is the distance established by “the junctional epithelium and connective tissue attachment to the root surface” of a tooth . This distance is important to consider when fabricating dental restorations , because they must respect the natural architecture of the g. . .
