Resorbable membranes are well described and employed for horizontal guided bone regeneration (GBR). However, available literature lacks in providing information on the bone volumetric changes during the healing that follows GBR procedures and dental implant placement. This presentation will show a method to analyze the volumetric bone changes after treating pristine edentulous mandibular defects with lateral GBR using freeze-dried bone allograft (FDBA) and collagen resorbable membrane. The time like will be followed but clinical cases representative of the project. Clinical changes in bone volume before and after GBR were measured. In addition, digital volumetric analysis of the augmented ridges was performed preoperatively, as well as 3 and 6 months after the GBR procedure. At the time of dental implant placement, bone cores were collected during the osteotomy for histologic analysis. Data on volume changes showed a mean volume resorption between 3 and 6 months of 5% ± 3.78%. Histologic bone core analysis showed 48% mineralization content in the area of augmentation. In conclusion, resorbable membranes exhibited reliability for GBR in intercalated mandibular defects, providing sufficient bone volume gain at ≥ 6 months for implant stabilization and limited resorption during graft healing.
