The importance of restorative margin placement to the biologic width and periodontal health. Part II

Part I of this article presented the rationale for the use of the crown-lengthening procedure prior to final prosthetic or restorative treatment. The primary objective of the procedure is the attainment of a periodontal biologic width, free of any invasive restorative dentistry, circumferentially around the tooth. Part II of this article presents a clinical case to demonstrate, step by step, the crown-lengthening procedure. Concurrently the clinical rationale for these steps is also explained.
