Preliminary results with the use of ossifying collagen membranes in the horizontal alveolar defects treatment after dental implant placement
| Resumo: | Introduction: Rehabilitation with dental implants is a treatment that has high success rate in the rehabilitation of partially or totally edentulous patients. Systemic diseases, periodontal diseases, trauma, tumors, and tooth extraction can lead to loss of bone volume and these bone defects limit the bone volume required for correct implant positioning. Objective: The aim of this study is to evaluate the clinical and radiographic results of dental implant placement in edentulous ridges treated with a collagen membrane with ossifying properties for horizontal augmentation of the lost ridge volume. Materials and Methods: This study evaluated the volumetric changes at the buccal level by superimposing digital files. The variables obtained were Buccal Volume variation (BVv) and Mean Buccal Variation (MBV). In terms of marginal bone changes, periapical radiographs were taken at two times: baseline (T0) and 6 months (T1) after implant insertion simultaneously with the placement of a OSSIX Volumax collagen membrane. These changes were characterized in two variables, mesial Marginal Bone Changes (mMBC) and distal Marginal Bone Changes (dMBC). Statistical significance was set at P 0,05. Results: The use of these cross-linked membrane showed an average increase of 32.06% in terms of volumetric changes (BVv) and 0.97mm at the linear measurements of the alveolar surface (MBV). In terms of marginal bone changes the results showed a mean bone reduction of 0.75mm between T0 and T1 for the mesial sites (mMBC) and 0.80mm for the distal sites (dMBC). Conclusion: The use of OSSIX Volumax membrane is associated with a buccal volume gain, however in terms of marginal bone maintenance the results were not statistically significant and no improvement was noticed comparing with the literature outcomes. |
