Journal of Oral Science & Rehabilitation 16 Volume 2 | Issue 4/2016 O p e n h e a l i n g : A r e t r o s p e c t i v e a n a l y s i s Open-healing approach to avoid flap mobilization and subsequent morbidity Abstract O b j e c t i v e This retrospective analysis evaluated the outcome of bone regeneration using membranes in an open-healing approach. M a t e r i a l s a n d m e t h o d s : In 119 patients with 160 surgical areas, ridge preservation or bone aug- mentation was performed. Bone defects were filled and covered with a membrane that was left exposed during healing. Outcome parameters were the need to perform an unplanned augmentation and complication rates during wound healing. R e s u l t s Boneaugmentationwasperformedin33.1%,ridgepreservationin41.9% and ridge preservation combinedwith bone augmentation in 13.1% ofthe surgical areas. In 78.8% of the surgical areas, a native bilayer collagen membrane was used. Healing was uneventful in 90.6% of the surgical areas. Complications occurred in 9.4% ofthe surgical areas and included premature membrane resorption, hematoma, membrane loosened by tongue,pain,wounddehiscenceandfracturedboneplateduringaugmen- tationsurgery.Onepatientdevelopedanabscess,onelostanimplant.The graft was partially lost in 1.9% of the surgical areas. Implants could be inserted as planned in a two-stage procedure in all but the one surgical area in which the abscess had occurred. In this area, an unplannedre-augmentationwasrequired.In86.9%ofthesurgicalareas, no re-augmentation was necessary. Secondary augmentation was per- formed in 12.5% according to the treatment plan.

This approach may help to avoid soft- tissue problems associated with extensive flap mobilization and tension. K e y w o r d s Collagen membrane, open healing, ridge preservation, augmentation.
