Sponsor's own description

On many occasions, clinicians find situations in which they have to perform extractions of erupted or semi-erupted third molars or wisdom teeth where there are pre-existing periodontal pockets distal to the second molars, caused by a bone defect due to periodontal disease or due to malposition of the wisdom tooth concerning the second molar.

After the extraction of an erupted or semi-included third molar, and as a consequence of factors related to dental malposition or bone defects caused by periodontal disease, periodontal pockets can arise on the distal surface of the second molar.

When such exodontia is performed conventionally without raising a flap or applying any suturing technique in which there is a primary closure of the wound, there is a greater probability of persistence of periodontal pockets; and, in the worst case, they may increase after healing and closure of the alveolus. The consequence would be the formation of an enlarged and unattached tissue on the distal aspect of the second molar.

The fact that periodontal pockets persist acts as an unfavorable prognostic factor. The predictive power of subsequent periodontal destruction increases since these are areas where bacteria will continue to accumulate (etiological factor of periodontal disease), and where the patient will not be able to access for their elimination and control. This is why a surgical technique called "distal wedge" has been proposed to eliminate these pockets.

To avoid this second surgical procedure, we propose a procedure immediately after the conventional exodontic technique; where after performing a small gingivectomy and lifting a mucoperiosteal flap based on periodontal respective surgery concepts, primary closure of the alveolus and repositioning of the flaps at the level of the bone crest is achieved, eliminating these pre-existing pockets. This requires the existence of sufficient keratinized gingiva to maintain a band of at least 2 mm of keratinized tissue after the gingivectomy, thus ensuring a correct adherent tissue that provides sealing and proper maintenance of the periodontal tissues around the tooth. The proposed technique has been termed a "distal reduction flap" (DRF).
