Case Report: Coverage of denuded labial bone resulting from post space preparation with a free gingival autograft: lessons learnt

摘要

Rehabilitation of endodontically treated teeth by post and core preparation is a common procedure in day to day dental practice. However, in some instances, post space preparation can produce excessive frictional heat leading to significant damage to the attachment apparatus of the tooth as well as to the overlying soft tissue. This report describes a case of mucosal dehiscence arising due to trauma induced by inadvertent post space preparation. The denuded mucosa was restored to its physiological position with the help of free gingival autograft obtained from the palatal donor site. The aesthetic results obtained were excellent and have been stable for a period of 2 years.
