“…Bone repair in rabbits was three times faster than that in humans. There was no significant difference in the percentage of newly formed bone in the sixth and the ninth month post-sinus lifting in human, 42 similar fact also found in this study in rabbits.…”

Bovine origin matrix has been widely used in clinical applications and investigated by various research institutions. However, the potential factors that influence bone regeneration are still not thoroughly understood and need further investigations. In this study, bone regeneration properties of anorganic bovine bone matrix (ABBM), organic-containing bovine bone matrix (OBBM), and widely acknowledged anorganic bovine bone matrix (Bio-Oss) were compared. Besides, the correlations between physiochemical characterizations and bone regeneration properties of the three xenografts were also investigated. Physiochemical characterizations were measured by special instrumentations. In animal studies, the three xenografts were implanted into 8-mm-diameter cranial defects of 16 New Zealand white rabbits. The biological effects were evaluated by micro-computed tomography and histomorphometric analysis after 6 and 12 weeks of implantation. The physical characterizations showed that anorganic bovine bone matrix and Bio-Oss had more nanostructures, larger surface area, bigger pore volume, and bigger pore size than that of organic-containing bovine bone matrix. The chemical characterizations showed that anorganic bovine bone matrix and Bio-Oss had higher crystallinity than that of organic-containing bovine bone matrix, and organic-containing bovine bone matrix contained organic nitrogen (N) component. In vivo, anorganic bovine bone matrix and Bio-Oss possessed better bone regeneration properties than that of organic-containing bovine bone matrix. Taken together, nanostructures, larger surface area, bigger pore volume, and bigger pore size of xenografts played an active role in new bone formation. Besides, lower crystallinity and organic N element of xenografts produced a positive effect on graft degradation. The abovementioned findings could provide theoretical basis for better choice in clinical applications and better manufacturing hydroxyapatitederived bone graft in the future.

“…Obviously at that time the tissues at the augmented sinus floor provide a sufficient support for implants to bear function loading. In the literature there are few reports of such a short consolidation period (12,13). The mean marginal bone resorption for both methods is similar -0,174mm for procedures with simultaneous implant placement and 0,167mm for the method with stage implant placement.…”

IntroductionThe aim of this study is to evaluate sinus floor elevation utilizing the lateral approach and simultaneous or stage implant placement as a reliable treatment of edentulism in the posterior areas of the upper jaw with vertical bone deficit. Material and MethodsWe considered as indicated for sinus floor elevation utilizing the lateral approach, patients, who had subantral bone deficit, which was caused by pneumatization of the maxillary sinus in cases with normal distance between the edentulous alveolar crest and the occlusal surface of the opposite teeth or to the occlusal plane. Patients were scanned via cone-beam computer tomography. The sinus floor elevation utilizing the lateral approach was performed with simultaneous implant placement or with stage implant placement. The following criteria were observed: presence of intraoperative and early postoperative complications, survival rate for the period of study, bleeding on probing, and marginal bone resorption. ResultsThe observation period is 4 to 5 years. The survival rate of the implants placed simultaneously with the sinus floor elevation utilizing the lateral approach is 99.2%, as for the stage implant placement it is 100%. The mean period for stage implant placement is 5.28 months after the subantral bone augmentation. The simultaneously placed implants were loaded 4 to 5 months after the placement and the stage placed implants -after 6 months.

“…GBR with simultaneous implant placement and ISBG in a combination with pericardium collagen membrane showed complete bone defect regeneration, long-lasting volume stability and soft tissue aesthetics in patients that were monitored for 2-5 years [24]. Even though ISBG showed higher volumetric loss than bovine xenografts in maxillary sinus floor augmentation procedures after three years follow up, there was no significant difference in new bone formation between 6th and 9th month [25,33]. Here the mean percentage of new bone was 15% and 21%, respectively.…”

Background and objective: Injectable synthetic bone grafts (ISBG) are widely used biomaterials for regeneration purposes. The aim of this case report was to examine the efficacy of ISBG in the management of buccal fenestration in the case of a 25-year-old female. Case report: After a traumatic tooth extraction, the defect was filled with ISBG and covered with a resorbable membrane. The ISBG showed easy handling and the patient had no complications during healing. Six months after augmentation, a bone biopsy was taken during implant bed preparation. The histological results showed good integration of ISBG into the newly formed bone and no signs of tissue inflammation. Additionally, a CBCT (cone beam computed tomography) analysis was performed to support the histological results. Conclusion: The use of the examined ISBG led to successful treatment of the buccal fenestration defect.
