PURPOSE The concept of biologic width forms a basis for successful peri-implant soft tissue integration around titanium implants. Therefore, the objectives of this review are to determine and critically evaluate the present knowledge about biologic width around implants and to establish future research trends. MATERIALS AND METHODS The literature was selected through several electronic databa...

one of the most commonly used procedures in contemporary periodontics. Indications include: (1) lack of sufficient length of a clinical crown to ensure a tooth preparation for fixed prosthodontics with retentive and resistance form; (2) preexisting dental caries or restorations in the vicinity of the free gingival margins that prevent preparation of finish lines for restorative margins coronal ...

Esthetic outcomes cannot be attributed to a single parameter. Rather, as this article shows, they are the result of a number of important factors, especially in the esthetic zone. An understanding of the meaning of biologic width, of the integration of the platform-switching concept into implant treatment facilitates the preservation of a stable marginal bone level around the implant neck. This...

The two-cord retraction technique is used for troughing around a crown to achieve biologic width. This technique can cause significant discomfort for the patient and offers several potential clinical disadvantages for the dentist, of which unpredictable tissue recession is the most significant. The clinical case presented in this article compares the use of the standard two-cord retraction tech...

This is the report of a case of four upper incisors with multiple internal/external resorptions after a falling accident in the childhood and subsequent violation of the biologic width by incorrect individual coronal restorations. Endodontic orthograde retreatment was performed and mineral trioxide aggregate (MTA) was placed as apical plug and to repair the large internal resorption. In order t...

Histological analysis of the biological width surrounding primate teeth offers insights into why the blood supply is reduced after tooth extraction and implant placement. This occurs because of the reduction of ridge width and height. The reduction in blood supply tends to be exacerbated as development of a new biologic width after implant placement causes facial bone to be lost both vertically...
