The influence of collagen membrane and autogenous bone chips on bone augmentation in the anterior maxilla: a preclinical study

Abstract

The addition of autogenous bone chips and the presence of the collagen membrane increased bone formation around DBBM particles. Wound protection from mechanical noxa during early healing may be critical for bone formation within the grafted area.

Comparison of different grafting materials for treatment of bone defect distal to the molar in canine

“…32 Deproteinized bovine bone mineral is a natural, nonantigenic, porous bone mineral matrix produced by removing all organic components from bovine bone. 39,40 However, the analysis of fluorochrome labeling at 4week intervals (Figure 4) and the result of histological examination (Figure 5) in this study indicated that even with the CM, the slow degradation of DBBM does not offer enough space, and hinder the new bone growth over 12-week period. 33 Deproteinized bovine bone mineral was selected in our study because it has been widely used in the oral and maxillofacial practice, and has shown satisfactory results.…”

“…The addition of CM has been proved to be effective in increasing new bone formation. 39,40 However, the analysis of fluorochrome labeling at 4week intervals (Figure 4) and the result of histological examination (Figure 5) in this study indicated that even with the CM, the slow degradation of DBBM does not offer enough space, and hinder the new bone growth over 12-week period. This was in agreement with the findings of 2 former studies.…”

“…The membrane was not used in the group Ta, because the AB has good osteo-induction and fast revascularization, and our previous clinical study did not use membrane either. However, the previously published study 39 confirmed that AB combined with membrane yielded better clinical and histological outcomes in the treatment of buccal dehiscence-type defects. Graft AB alone or combined with membrane should be assessed in further clinical study.…”

Implant survival rate in calvarial bone grafts: A retrospective clinical study with 10 year follow‐up

“…1,19,20 Cortical blocks were then shaped on the alveolar bone defects to obtain the maximum contact surface between grafts and the recipient site, promoting the integration process 21 ( Figure 5). 23 Periosteal incisions were performed prior to wound closure to release flaps, allowing for tension-free suturing. Cancellous bone chips were used to fill gaps between grafts and the receiving bone walls.…”
