ABSTRACT

Purpose: The purpose of this case series was to evaluate the effect of guided bone regeneration using demineralized allogenic bone matrix with calcium sulfate.

Materials and methods: Guided bone regeneration using Demineralized Allogenic Bone Matrix with Calcium Sulfate (AlloMatrix™, Wright. USA) was performed at the time of implant placement from February 2010 to April 2010. At the time of the second surgery, clinical evaluation of bone healing and histologic evaluation were performed. The study included 10 patients, and 23 implants were placed. The extent of bony defects around implants was determined by measuring the horizontal and vertical bone defects using a periodontal probe from the mesial, distal, buccal, and lingual sides and calculating the mean and standard deviation of these measurements. Wedge-shaped tissue samples were obtained from 3 patients and histologic examination was performed.

Results: In clinical evaluation, it was observed that horizontal bone defects were completely healed with new bones, and in the vertical bone defect area, 15.1% of the original defect area remained. In 3 patients, histological tests were performed, and 16.7-41.7% new bone formation was confirmed. Bone graft materials slowly underwent resorption over time.

Conclusion: AlloMatrix™ is an allograft material that can be readily manipulated. It does not require the use of barrier membranes, and good bone regeneration can be achieved with time.

Figure 1: Revitalization of the implant chips (white asterisks) with some degree of woven formation around the implant chips. Absorbing implant chips (black asterisks) were found in the fibrous tissue.

Mentions: Tissues samples were obtained from the mandibular molar area of a 51-year-old female patient after 3 months. Revitalization of the implant chips with some degree of woven formation around the implant chips was noted. Absorbing implant chips were found in the fibrous tissue. Neither inflammatory cell infiltration nor granulomatous reaction was noted. Histomorphometric analysis was performed. New bone formation was 16.7%, and the ratio of lamellar bone to woven bone to residual graft materials was 0:43:57 (Fig. 1). Tissue samples were obtained from the maxillary left molar area of a 68-year-old male patient 4.5 months after GBR. Active woven bone formation was identified around the implant chips. Some areas showed bony trabeculae forming anastomosis. Neither inflammatory cell infiltration nor granulomatous reaction was noted. New bone formation was 41.7%, and the ratio of lamellar bones to woven bones to residual graft material was 0:89:11 (Fig. 2). Tissue samples were obtained from the maxillary left first molar area of a 75-year-old male patient after 5.5 months. Active woven bone formation was identified around the implant chips. Most of the implant chips were absorbed, but some particles were isolated in the fibrous tissue. Neither inflammatory cell infiltration nor granulomatous reaction was noted. New bone formation accounted for 27.3% of the tissue area quantified; the lamellar bone: woven bone: residual graft material ratio was 0:88:12 (Fig. 3).
