Abstract
IntroductionPatient‐, site‐, and procedure‐related factors important for successful periodontal regeneration have been defined in the periodontics literature by insightful clinician‐researchers. Prevention of bacterial contamination of the surgical site through careful wound closure and meticulous postoperative care is a critical procedure‐related factor necessary for periodontal regeneration. Dense polytetrafluoroethylene (dPTFE) is a nonresorbable barrier material that may protect bone replacement grafts (BRG) against bacterial contamination for a short period during early wound healing if membrane exposure occurs.Case PresentationA 35‐year‐old African American female with a deep/narrow infrabony periodontal defect and Hamp degree I furcation involvement at tooth #14 (mesial) underwent combination BRG/guided tissue regeneration (GTR) using a mineralized/demineralized freeze‐dried bone allograft and a dPTFE barrier membrane. Favorable clinical and radiographic outcomes were noted nine months following the procedure.ConclusionsTwo reports evaluating clinical parameters following use of dPTFE membranes for GTR appear in the literature. The present case provides clinical and radiographic outcome assessments following combination BRG/GTR using a dPTFE membrane. This material may be of interest for periodontal regeneration due to an ability to temporarily limit bacterial influence if membrane exposure occurs.
