Based on the clinical scenario, crown lengthening procedure is categorized as either esthetic or functional. Esthetic crown lengthening   is usually done in the anterior esthetic zone of oral cavity, where the major concern is to reduce excessive gingival display and increase the clinical crown height. While functional crown lengthening   is done to expose the crown structure so that a functional prosthesis can be placed over the exposed crown. Preservation of biologic width is the therapeutic endpoint of both these procedures. Crown lengthening can be limited to soft tissue only, or both soft and hard tissue can be contoured.   Indications- There are several indications including: restorative needs, to increase clinical crown height lost due to caries, fracture or wear, to access sub-gingival caries, to ac...
