“…The standard procedure for sinus-floor elevation is by raising the Schneiderian membrane and filling the cavity with bone, biomaterials, or a combination of both (Thorwarth et al, 2005;Choukroun et al, 2008;Cordaro et al, 2008;Froum et al, 2008;Kirmeier et al, 2008).…”

“…The standard surgical technique for sinus-floor elevation involves raising the sinus mucous membrane and filling the cavity with either bone or biomaterials, or a combination of these. The materials utilized comprise of autogenous bone (Thorwarth et al, 2005), allogenous bone (Choukroun et al, 2008), xenogenous substitutes (Beloti et al, 2008), synthetic materials (Froum et al, 2008) or a combination of these materials (Kirmeier et al, 2008). Regardless of increased morbidity (Silva et al, 2006), autogenous bone is still the gold standard for reconstructive procedures (Raghoebar et al, 1993).…”

SUMMARY.Background: Several studies have reported certain bone morphogenic proteins (BMPs) to have positive effects on bone generation. Although some investigators have studied the effects of human recombinant BMP (rhBMP-2) in sinus augmentation in sheep, none of these studies looked at the placement of implants at the time of sinus augmentation. Furthermore, no literature could be found to report on the impact that different implant systems, as well as the positioning of the implants had on bone formation if rhBMP-2 was utilized in sinus-lift procedures. Purpose: The aim of this study was to compare sinus augmentation with rhBMP-2 on a poly-D, L-lactic-co-glycolic acid gelatine (PLPG) sponge with sinus augmentation with autologous pelvic cancellous bone in the maxillary sinus during the placement of different dental implants. Materials and methods: Nine adult female sheep were submitted to bilateral sinus-floor elevation. In one side (test group) the sinus lift was performed with rhBMP-2 on a PLPG-sponge, while the contralateral side served as the control by using cancellous bone from the iliac crest. Three different implants (Bränemark Ò , 3i Ò and Straumann Ò ) were inserted either simultaneously with the sinus augmentation or as a two staged procedure 6 weeks later. The animals were sacrificed at 6 and 12 weeks for histological and histomorphometrical evaluations during which boneto-implant contact (BIC) and bone density (BD) were evaluated. Results: BD and BIC were significantly higher at 12 weeks in the test group if the implants were placed at the time of the sinus lift (p \ 0.05). No difference was observed between the different implant systems or positions. Conclusions: The use of rhBMP-2 with PLPG-sponge increased BIC as well as BD in the augmented sinuses if compared to autologous bone. Different implant systems and positions of the implants had no effect on BIC or BD. Ó 2010 European Association for Cranio-Maxillo-Facial Surgery

“…Twenty-five articles met our inclusion criteria. Frequently (17), autologous bone volume percentages were extracted from comparative experiments in which they were used as a control group. The majority of these 25 articles were prospective controlled studies (21) and 2 randomized clinical trials, 1 pilot study and 1 case series.…”

Background: To date, no studies have been published that evaluated histomorphometric data from a large number of patients while comparing different sites and methods of autologous bone grafting in sinus floor augmentation procedures. A meta-analysis of the English literature from January 1995 till April 2009 was carried out. Results: Out of 147 titles, according to our criteria, 25 articles were left for analysis. The majority were prospective controlled studies (21) and 2 randomized clinical trials, 1 pilot study and 1 case series. A reference value of 47% for total bone volume (TBV) was found while using iliac bone grafting as a standard. Use of intraoral bone grafts increases the TBV, with 11% for chin bone and 14% for bone grafted from other intraoral sites. Particulation of the bone graft has a negative effect on the TBV of 18%. Surprisingly, no correlation between TBV and the time of graft healing was found. Histological section thickness seemed to be a significant variable, as every micron increase of section thickness leads to an increase of 0.4% of TBV. Conclusions: Bone grafting from the iliac crest resulted in a significantly lower TBV compared with intraoral bone grafting. However, due to the limited availability of intraoral bone to be harvested, iliac grafts still have to be considered the gold standard in augmenting the severely atrophic maxilla.
