Abstract
Objectives : The aim of this study was to evaluate the effects of a composite of bone substitute and collagen barrier membrane (bone patch) for local ridge augmentation at peri-implant dehiscence defects on the clinical efficacy and positional stability in dogs. Materials and methods : Implant placement and ridge augmentation procedure were performed at surgically created periimplant dehiscence defects in canine mandible (n=6). Four treatment modalities were randomly applied: i) bone patch group, ii) Guided bone regeneration (GBR) without pin fixation group (bone graft and collagen membrane), iii) GBR with pin fixation group, and iv) negative control group. After 12 weeks, clinical, micro-CT and histological analyses were performed.
Results : Histologic analysis showed that bone patch group had similar results to GBR group and GBR with fixation group in
terms of new bone formation. Micro-CT analysis revealed similar results to histologic analysis in terms of total volume
maintenance. Operating time was shorter in bone patch group compared to GBR group and GBR with fixation groups.
Conclusions : GBR using bone patch could simplify the ridge augmentation procedure with reduced operating time and
equivalent biological performance compared to the conventional procedure.
