INTRODUCTION:
Alveolar ridge preservation is a widespread term, which describes the methods of reducing hard and soft tissue loss following tooth extraction and thus preserving optimal tissue volume for future implant placement and prosthodontic rehabilitation. Various techniques give promising, long-term results. Some of them utilize the use of barrier membranes. Their function is to isolate the intrabony defect from rapidly growing tissues. There are two main types of barrier membranes—resorbable and non-resorbable, both having their characteristics, advantages, and disadvantages.
AIM:
The present review aims to observe the use of non-resorbable dense polytetrafluoroethylene (dPTFE) membranes for ridge preservation and evaluate its advantages, limitations, and success rate according to the literature. The collected data was carefully systematized in a comparative, concise, and unbiased review of the application of dPTFE membranes.
MATERIALS AND METHODS:
This review is based on 56 articles, researches, case reports, retrospective studies, and controlled clinical trials. It provides a meticulous analysis of the existing electronic database.
RESULTS:
There is growing evidence that the utilization of dPTFE membranes successfully preserves the dimensions of the alveolar ridge, increases the width of the keratinized tissues, and preserves the place of the mucogingival junction. When using them, primary wound closure is not mandatory and the membrane can be easily removed after four weeks.
CONCLUSION:
The use of dPTFE for ridge preservation should be considered a reliable and successful method. Although they have some limitations, most of the studies report in favor of their utilization.
