Crown Lengthening: Indications, Techniques, and Its Effect for the Biological Width

Abstract

Crown lengthening is a viable procedure that allows teeth with a short clinical crown, extensive subgingival caries, and subgingival tooth fractures at the dentogingival junction to be restored. When performed in ideal clinical conditions, crown lengthening provides satisfactory functional and aesthetic results. To maintain optimal form, function, esthetics, and comfort of the dentition, a thorough knowledge of the relationship between periodontal tissues and restorative dentistry is essential.
