Modified Root Submergence Technique for Pontic Site Development in Maxillary Anterior Region.

ABSTRACT

Extraction of tooth leads to alveolar ridge resorption, which is more pronounced in the 1st year after extraction. Ridge resorption results in loss of interdental papillae and creation of unesthetic black triangles. Root submergence technique (RST) is a procedure where the tooth is decoronated and submerged at or below the alveolar bone level. The goal of the technique is to maintain the attachment complex of the tooth, which will prevent the alveolar bone resorption at the site with maintained soft tissue profile resulting in better esthetic results. The present case describes a relatively bloodless and minimally invasive modified RST that can be implemented in routine clinical practice with the predictable esthetic outcome.
