EVALUATION OF THE USE OF SONICWELD® RESORB X® FOIL MEMBRANES IN THE REPAIR OF OROANTRAL FISTULA
INTRODUCTION: There is a variety of treatment modalities for oroantral defects relying on repair of soft tissue component only of the defect. However, guided bone regeneration (GBR) is needed to allow the simpler later restoration of the missing tooth.
OBJECTIVE: The aim of this study was to evaluate the efficacy of using Sonicweld® Resorb X® foil membranes as a type of GBR in oroantral defects.
METHODOLOGY: This study was conducted on fourteen patients suffering from oroantral defects of more than three weeks duration and having a width of at least five millimeters (mm). The patients were divided into two groups;
Group I (study group): Seven patients were treated with placement of Sonicweld® Resorb X® foil membranes along with buccal advancement flap.
Group II (control group): Seven patients were treated with only buccal advancement flaps.
RESULTS: There was a significant difference in the wound healing and pain scores of the intermediate follow-up period between the two groups, with mainly group I having worse scores than group II. But at the end of the follow-up period, there was no significant difference between the two groups.
CONCLUSION: Sonicweld® Resorb X® foil membranes were shown in this study to prolong the time of healing of the soft tissue flap in oroantral defects, with minimal ability of bone formation in the oroantral defect. Further studies are needed in this field, with greater sample size of study group, and the trial of the membrane with other types of soft tissue flaps.
