Abstract Background The purpose of this study was to evaluate the volumetric changes in partially edentulous alveolar ridges augmented with customized titanium ridge augmentation matrices (CTRAM), freeze-dried bone allograft, and a resorbable collagen membrane. Methods A pre-surgical cone beam computed tomography (CBCT) scan was obtained for CTRAM design/fabrication and to evaluate pre-surgical ridge dimensions. Ridge augmentation surgery using CTRAM, freeze-dried bone allograft, and a resorbable collagen membrane was performed at each deficient site. Clinical measurements of the area of augmentation were made at the time of CTRAM placement and re-entry, and a 2nd CBCT scan 7 months after graft placement was used for volumetric analysis. Locations of each CTRAM in situ were also compared to their planned positions. Re-entry surgery and implant placement was performed 8 months after CTRAM placement. Results Nine subjects were treated with CTRAM and freeze-dried bone allograft. Four out of the nine patients enrolled (44.4%) experienced premature CTRAM exposure during healing, and in two of these cases, CTRAM were removed early. Early exposure did not result in total graft failure in any case. Mean volumetric bone gain was 85.5 ± 30.9% of planned augmentation volume (61.3 ± 33.6% in subjects with premature CTRAM exposure vs. 104.9% for subjects without premature exposure, p = 0.03). Mean horizontal augmentation (measured clinically) was 3.02 mm, and vertical augmentation 2.86 mm. Mean surgical positional deviation of CTRAM from the planned location was 1.09 mm. Conclusion The use of CTRAM in conjunction with bone graft and a collagen membrane resulted in vertical and horizontal bone gain suitable for implant placement.

Abstract Deep bone defects are caused by the progression of periodontal disease, which breaks down bone and connective tissue that hold teeth in place. In this case, a 37-year-old male patient presented a deep bone defect with advanced periodontal disease around an upper canine. Medical-grade calcium sulfate was mixed with demineralized freeze-dried bone allograft and used to repair and regenerate the defect. Analysis of the radiographs at the 5-month time point showed the bone had completely regenerated.

Abstract Clinicians often have difficulty with the diagnosis and treatment of root perforation. This paper reports two patients with root perforation treated with periodontal surgery associated with guided tissue regeneration (GTR) and demineralized freeze-dried bone allograft (DFDBA). This combined treatment resulted in minimal probing depths, minimal attachment loss, and radiographic evidence of bone gain after follow-up evaluations that ranged from 2 to 4 years. These case reports show a correct diagnosis and removal of etiologic factors can restore both periodontal and endodontic health. Citation Zenobio EG, Shibli JA.

Treatment of infrabony pocket makes use of bone graft material demineralized freeze dried bone allograft (DFDBA) from different individuals which has undergone demineralization process and it is osteoinductive. Enhancement of growth factor was done by adding platelet rich fibrin (PRF) and platelet rich plasma (PRP). PRP is activated with an addition of calcium chloride CaCl2) to form gel. The method used to apply the bone grafting material is open flap debridement OFD). This research aimed to reveal the differences in the results of infrabony pocket treatment using PRF and PRP gel with an addition of DFDBA. The sample was taken from 20 infrabony pocket points divided into 2 groups, 10 infrabony pocket were treated with OFD+DFDBA+PRF and the other were treated with OFD+DFDBA+PRP gel. Pocket depth (PD) was measured on the baseline and the first and third month after treatment. Alveolar bone height was measured using cone beam computed tomography (CBCT) radiograph on the baseline to the third month after treatment. The results of this research showed that there was difference in the results of infrabony pocket treatment using PRF and PRP gel with an addition of DFDBA which could be observed from a reduction in PD from the baseline, month 1 and month 3 as well as reduction in alveolar bone height from the baseline to month 3. This research concluded that infrabony pocket treatment PRF application yields better results than PRP gel application in terms of PD and alveolar bone height reduction.
