The purpose of this study was to compare the efficacy between the use of bovine bone graft material and platelet-rich fibrin (PRF) mixture (test group) and bovine bone graft material and collagen membrane combination (control group) in 2-stage maxillary sinus augmentation. According to specific inclusion/exclusion criteria, patients treated between 2008 and 2012 were selected. Panoramic radiographs were used for radiologic assessments. To evaluate the relationship between sinus-graft height and each implant, the bone level (BL) was divided by implant length (IL). To evaluate the change in the height of grafted sinus, the grafted sinus floor above the lowest part of the original sinus height (GSH) was divided by the original sinus height (OSH). Samples taken during implant surgery were used for histologic and histomorphometric analyses. Twenty-five patients, 32 augmentation surgeries, and 66 one-stage implants were included in the study. No implant loss or complication was observed in either group. There were no statistical differences according to new bone formation (P = .61) and biomaterial remnant (P = .87). During the evaluation period, the test group showed statistically less change in the BL/IL ratio (P = .022). The difference of GSH/OSH ratio was found to be insignificant between groups (P = .093). It was observed that the grafted sinus covering the implant apex and sinus floor was above the original sinus height in both groups. It may be concluded from this study that both combinations can be successfully used for sinus augmentation. Further studies evaluating different graft materials and PRF combinations in the early phases of healing would be beneficial.

The purpose of this study was to compare the histologic and radiologic differences between single- and double-layer collagen membrane techniques in flapless ridge preservation. The mandibular fourth premolar and first molar of four beagle dogs were used in the experiment. Mesial roots of the teeth were extracted and root canal treatment was performed at the distal roots. Ridge preservation was performed at the extraction sites using synthetic bone graft material. A single layer (control group) or double layer (test group) of non-crosslinked collagen membrane was applied following bone graft application. Three months later, the animals were sacrificed and micro-computed tomography (micro-CT) and histomorphometric analyses were conducted. Nonparametric Mann–Whitney test was performed to compare between the control and test groups. The vertical difference between buccal and lingual crests of control and test groups was 1.28 ± 0.41 and 0.53 ± 0.37 mm, respectively (p = 0.026). The mineralized bone area in control and test groups was 31.48% ± 7.41% and 42.25% ± 9.73%, respectively (p = 0.041). Within the limit of this study, ridge preservation using the double-layer membrane technique showed a reduced buccal bone resorption and improved new-bone formation in the ridge compared to that using the single-layer membrane technique.

This study is aimed at assessing the dimensional alterations occurring in the alveolar bone after premolar extraction in dogs with histomorphometric and histological analysis. After atraumatic premolar extraction, tooth-derived bone graft material was grafted in the extraction socket of the premolar region in the lower jaws of six dogs in two experimental groups. In the second experimental group, BM-MSCs were added together with the graft. The control was left untreated on the opposite side. After twelve weeks, all six animals were sacrificed. Differences in alveolar bone height crests lingually and buccally, and alveolar bone width at 1, 3, and 5 mm infracrestally, were examined. Histologic study revealed osteoconductive properties of tooth biomaterial. A statistically significant difference was detected between the test and control groups. In the test groups, a reduced loss of vertical and horizontal alveolar bone dimensions compared with the control group was observed. Tooth bone graft material may be considered useful for alveolar ridge preservation after tooth extraction, as it could limit the natural bone resorption process.

Platelet-rich fibrin (PRF) is an autologous material used to improve bone regeneration when associated with bone grafts. It affects tissue angiogenesis, increasing the healing process and, theoretically, presenting potential to increase bone neoformation. The aim of this study was to verify, histomorphometrically, the effects of the association of PRF to a xenograft. Twelve adult white New Zealand rabbits were randomly assigned into two groups containing six animals each. After general anesthesia of the animals, two critical defects of 12 mm were created in the rabbit calvaria, one on each side of the sagittal line. Each defect was filled with the following biomaterials: in the control group (CG), xenograft hydrated with saline solution filling one defect and xenograft hydrated with saline solution covered with collagen membrane on the other side; in the test group (TG), xenograft associated with PRF filling the defect of one side and xenograft associated with PRF covered with collagen membrane on the other side. After eight weeks the animals were euthanized and a histomorphometric analysis was performed. The results showed that in the sites that were covered with collagen membrane, there was no statistically significant difference for all the analyzed parameters. However, when comparing the groups without membrane coverage, a statistically significant difference could be observed for the vital mineralized tissue (VMT) and nonmineralized tissue (NMT) parameters, with more VMT in the test group and more NMT in the control group. Regarding the intragroup comparison, the use of the membrane coverage presented significant outcomes in both groups. Therefore, in this experimental model, PRF did not affect the levels of bone formation when a membrane coverage technique was used. However, higher levels of bone formation were observed in the test group when membrane coverage was not used.

Time Point

Bone defects lead to aesthetic and functional losses, causing dental rehabilitation to be more difficult. The objective of this work is to histologically assess the hard tissue healing of bone defects filled with platelet-rich fibrin (PRF) alone or as an adjuvant for mixing with and covering anorganic bovine bone (ABB), compared to ABB covered with a resorbable collagen membrane (CM). This study was designed as a crossover animal study. Four 5-mm tibia defects, 5 mm apart from each other, were surgically created on the tibias of 6 sheep. The defects were randomly filled with ABB + CM; PRF alone; ABB+PRF; or were left empty. The animals were euthanized on days 10, 20, and 40 post-operatively. No group showed any signs of bone necrosis. Inflammation was observed in 2 control and 3 test defects with no statistically significant difference between groups at each time point. The ABB + CM and ABB + PRF groups experienced the highest bone regeneration ratios. No differences between the empty-defect and PRF groups were observed in regard to bone regeneration. No statistical difference was observed between the ABB+PRF and ABB + CM groups in regard to bone regeneration and the amount of residual graft material at each time point. The use of PRF should be preferred due to its autogenous origin, low cost, and ease of use.

The purpose of this study was to examine if the application of custom-made porous titanium membranes combined with bone graft materials promotes exophytic bone formation in rabbit calvaria. For this purpose, round decorticated calvaria sites were created using a round carbide bur. In the control group, rectangular parallelepiped-shaped porous titanium membranes (RPTMs) were placed on the decorticated sites and fixed with metal pins. In the experimental groups, RPTMs were filled with one of the following bone graft materials prior to fixing with metal pins: bovine bone mineral (BBM), demineralized freeze-dried human cortical bone (DFDB) or freeze-dried human cancellous bone (FDB). Animals were sacrificed at 8 and 12 weeks after surgery, and new bone formation was assessed by histomorphometric as well as statistical analysis. The results indicate that at 8 and 12 weeks, all the experimental groups demonstrated exophytic bone formation. At 12 weeks, DFDB group revealed the most new bone formation (p<0.05) and resorption of grafted materials (p<0.05). On the basis of these findings, we conclude that RPTMs may be used as an augmentation membrane for guided bone regeneration and DFDB as an effective bone-inducing graft material.

Background: Bone graft is an alternative therapy for periodontitis and other bone destructive lesions. Several studies had revealed Ellagic Acid (EA) ability in increasing osteogenesis process. EA contains polyphenols, such as Ellagitannin, Gallotannin, and Anthocyanin, which demonstrate anti-inflammatory and antibacterial activity as well as growth factor stimulating effect. EA combination with bone graft material (hydroxyapatite) is anticipated to enhance bone osteogenesis yet no investigation was performed to identify its toxicity towards fibroblast cell. Objective: To analyze EA toxicity on fibroblast cell in vitro. Methods: This was a true experimental study using post-test only with control group design. Fibroblast cell was exposed with EA in eight different concentrations: 0.1%, 0.2%, 0.5%, 1%, 2%, 3%, 4% and 5%. Control group comprised of cell control and media group. All groups were exposed to MTT Assay test and measured using Elisa Reader. Result: The calculation of cell viability value in EA groups at 0.1%, 0.2%, 0.5%, 1%, 2%, 3%, 4% and 5% concentration were 88.2%, 92.3%, 97.5%, 89.5%, 84.2%, 90.7%, 88.9% and 89.4% respectively. Conclusion: All EA and hydroxyapatite combinations are not toxic towards BHK-21 fibroblast cells.

Clinical Measurements

The purpose of this study was to evaluate the effect of the pool of bovine BMPs on the treatment of intrabony defects. The sample comprised 15 patients aged 26 to 57 years old presenting with 10 pairs of lesions of 2 or 3 walls or 2-3 walls ³5mm, located in the same type teeth (premolar or molar) and same jaw. The test defects were treated with combination of a pool of bovine bone morphogenetic and resorbable hydroxyapatite carrier (BMPs- HA), bovine demineralized bone matrix (MB) and coverage by a bovine collagen barrier membrane. The control defects were treated with MB-HA and covered by a bovine collagen membrane. The clinical measurements at six months after therapy in the test group revealed a reduction in the mean probing pocket depth (PPD) of 1.63 ± 1.41mm (B) and 1.93 ± 0.96mm (L) and a mean change in the clinical attachment level (CAL) of 1.60 ± 1.16mm (B) and 1.46 ± 0.97mm (L). The control group showed a mean reduction of PPD of 1.93 ± 1.34mm (B) and 2.0 ± 1.51mm (L) and a mean change of CAL of 1.03 ± 1.24mm (B) and 1.30 ± 1.14 mm (L). The analysis of variance (ANOVA) demonstrated that the changes in the clinical parameters were statistically significant (p<0.05). There were no significant differences between the test and controls subjects (Student's test, p<0.005). These findings suggest that the use of a pool of bovine BMPs do not provide added effects to GTR in the treatment of intrabony defects.

Block Bone Graft

Aim: To evaluate the effect on vertical bone augmentation of the screw tent-pole technique using particulate allograft in combination with injectable platelet-rich fibrin, and to compare this with autogenous block bone graft. Materials and Methods: This split-mouth randomized controlled study involved patients with bilateral partial edentulism and vertical bone loss in the posterior mandible. In each patient, the control side was treated with autogenous block bone graft harvested from the mandibular ramus and, on the test side, the screw tent-pole technique was employed, using particulate allograft in combination with injectable platelet-rich fibrin. All augmented sites were covered by leukocyte and platelet-rich fibrin membrane. The primary outcome variable of this study was the radiographic changes to bone height 6 months after augmentation. The secondary outcome variables were the percentage of newly formed bone and the implant survival rate. The data were analyzed with a significance level of α = 0.05. Results: Of the 13 patients included, a total of 11 patients (7 females, 4 males; mean age 50.92) completed the study. The mean values of vertical bone gain were 1.72 ± 0.78 mm for the test group and 2.83 ± 0.89 mm for the control group, which constitutes a significant difference ( P = .008). The percentage of newly formed bone was 18.08% ± 2.17% for the test group and 14.26% ± 1.76% for the control group. The difference between the groups was statistically significant ( P < .001). The implant survival rates were 100% for both study groups. Conclusions: Based on the study results, screw tent-pole can be considered a feasible technique for bone augmentation. Further randomized studies will be necessary to fully evaluate vertical bone augmentation using the screw tent-pole technique, with different graft materials and with larger samples.
