1. A prospective case series on surgical treatment of circumferential and semi-circumferential defects due to peri-implantitis
Abstract Different surgical treatment strategies for peri-implantitis with the use of graft material and membranes have been suggested without any longitudinal remarkable success rate. The present preliminary study was aimed to analyze a new clinical approach based on the disinfection of the implant connection, the disinfection of the implant surface and GBR

2. Bone repair induced by different bone graft substitutes in critical-sized defects in rat calvaria
Resumo Introdução A utilização de substitutos ósseos em procedimentos de enxertia de forma alternativa ao uso do osso autógeno tem sido indicada, entretanto a comparação direta entre esses biomateriais tem sido pouco explorada. Objetivo Avaliar o efeito de diferentes biomateriais osteocondutores sobre o reparo de defeitos críticos em calvárias (D

3. The effect of graft application and allopurinol treatment on calvarial bone defect in rats
Abstract Purpose: To investigate the effects of allopurinol administration on osteoinductive reaction and bone development with graft material. Methods: Thirty-six Wistar albino rats were divided into 3 groups. In the control group, calvarial bone defect was only created without any treatment. In the Defect + Graft group, allograft treatment was performed

4. Bioactive glass added to autogenous bone graft in maxillary sinus augmentation: a prospective histomorphometric, immunohistochemical, and bone graft resorption assessment
Abstract Objective The aim of this study was to compare the bone resorption rate, histomorphometry and immunohistochemical findings of bioactive glass (Biogran; Biomet, Warsaw, IN, USA) mixed with autogenous bone grafts (1:1) and autogenous bone graft isolate in maxillary sinus elevation surgery. Material and Methods A total of 9 maxillary sinuses were gra

5. Effects of local alendronate administration on bone defect healing. Histomorphometric and radiological evaluation in a rabbit model
Abstract Purpose: To performed a histomorphometric and radiological study to evaluate the effects of alendronate sodium administered locally in mandibular bone defects created in rabbits. Methods: Two circular defects 5 mm in diameter were created bilaterally in the mandibular corpus of 20 New Zealand rabbits (i.e., four defects per animal). Each defect

6. Correlation of Fractal Dimension with Histomorphometry in Maxillary Sinus Lifting Using Autogenous Bone Graft
O objetivo deste estudo foi determinar o padrão de remodelação óssea após levantamento de seio maxilar in humanos por meio de analise de dimensão fractal (FD) e histomorfometria. Além disso, a correlação entre FD e histomorfometria foi avaliada. Dezesseis pacientes com edentulismo na região posterior da

7. Immunolocalization of markers for bone formation during guided bone regeneration in osteopenic rats
Objective The aim of this paper was to evaluate the repair of onlay autogenous bone grafts covered or not covered by an expanded polytetrafluoroethylene (e-PTFE) membrane using immunohistochemistry in rats with induced estrogen deficiency. Material and Methods Eighty female rats were randomly divided into two groups: ovariectomized (OVX) and with a simu

8. The RANK/ RANKL/ OPG interaction in the repair of autogenous bone grafts in female rats with estrogen deficiency
The aim of this study was to evaluate the resorption process during the repair of autogenous bone grafts with or without coverage by an expanded polytetrafluoroethylene (e-PTFE) membrane in female rats with estrogen deficiency using the immunohistochemical technique. Eighty female rats were randomly divided into two groups (OVX and SHAM). The 40 female rats

9. Immunoexpression of PPAR-? and Osteocalcin Proteins for Bone Repair of Critical-Size Defects Treated with Fragmented Autogenous Abdominal Adipose Tissue Graft
A imunoexpressão das proteínas PPAR-γ e osteocalcina foi avaliada para o reparo ósseo de defeitos de tamanho crítico (DTC) criados em calvária de ratos (n = 42) e tratados com enxerto de tecido adiposo autógeno abdominal macerado. Foram formados três grupos (n=14): C (controlo - coágulo de sangue), AB (osso autógeno) e AT (tecido adiposo fragmentad

10. Virtual planning and construction of prototyped surgical guide in implant surgery with maxillary sinus bone graft
PURPOSE: To evaluate the efficacy of associating techniques of bone grafting in the maxillary sinus with the use of a prototyped surgical guide for planning and positioning dental implants in total edentulous maxillae, rehabilitated after six months. METHODS: Eight patients consecutives with totally edentulous maxilla presenting few remaining bone in the pos

11. Osso autógeno associado a osso bovino inorgânico (GenOx Inorg®) para aumento do soalho do seio maxilar e instalação de implantes: análise comparativa do potencial osteogênico de culturas de células derivadas do sítio doador e do sítio de implantação / The use of autogenous bone combined with anorganic bovine bone graft (GenOx Inorg®) for maxillary sinus augmentation and implat placement: a comparative analysis on the osteogenic potential of cell cultures derived from the donor site and the implant site
Objetivos: O objetivo desse estudo foi avaliar comparativamente o potencial osteogênico in vitro de células obtidas do ramo mandibular (RM, área doadora) e do seio maxilar enxertado com uma mistura de RM e osso bovino inorgânico (OBI), previamente à instalação de implantes de titânio (SM, sítio do seio maxilar enxertado). Material e Métodos: As cé

12. Estudo histológico dos tecidos conjuntivo e osteóide em enxertos ósseos com polímero de mamona : estudo experimental em ratos / Histological study of connective and osteoid tissue in bone grafts with castor oil polymer : experimental study in rats
The reconstruction of great bone loss defects represents a challenge for reconstructive surgery. To reconstruct these defects it is necessary to create conditions to stimulate new bone formation, in order to block the connective healing tissue growth towards the bony defect, which blocks the osteogenesis. The autogenous grafts are inconvenient, because they
