Abstract
Placement of gingival margins of different type of restorations has to be varied as per the extent of the defect and the restorative demands. Various factors tends to govern the margin placement. Over the years, as per the level of the free gingiva, restorative margins has been described as supra gingival, equigingival and subgingival. The concept of biologic width becomes important regarding the margin placement. This short communication discusses the concept of biologic width and the gingival margins of different restorations in respect to this concept.
Highlights
Maintenance of gingival health is essential for periodontal integrity.[1]
Violation of biologic width Biologic width is not to be encroached upon but generally it is violated in 2 situations
1) Where the tooth defect/ lesion is at the gingival margin or sub gingival.[5] 2) In anterior teeth, where due to aesthetic reasons, the margin has to be placed sub gingival.[5]
Summary
Maintenance of gingival health is essential for periodontal integrity.[1]. Restorative treatment is carried out without giving adequate importance to the surrounding gingival location. Such restorations both direct as well as indirect, could have far reaching adverse consequences. In order to maintain their optimal health, knowledge of gingival attachments and their interrelationship with the restorative margins becomes essential.[2]. 2. Biologic width Biologic width has been a debatable topic for the last 4-5 decades. Biologic width Biologic width has been a debatable topic for the last 4-5 decades Earlier it was considered a band of soft tissue encircling and attaching the gingiva with the cervical margin of the tooth [3].
