1. Effect of stem cells combined with a polymer/ceramic membrane on osteoporotic bone repair
Abstract Cell therapy associated with guided bone regeneration (GBR) can be used to treat bone defects under challenging conditions such as osteoporosis. This study aimed to evaluate the effect of mesenchymal stem cells (MSCs) in combination with a poly(vinylidene-trifluoroethylene)/barium titanate (PVDF-TrFE/BT) membrane on bone repair in osteoporotic rats.

2. A comparison of different bone graft materials in peri-implant guided bone regeneration
Abstract The aim of this study was to compare the effects of hydroxyapatite (HA), deproteinized bovine bone (DPB), human-derived allogenic bone (HALG), and calcium sulfate (CAP) graft biomaterials used with titanium barriers for bone augmentation to treat peri-implant defects in rat calvarium treated by guided bone regeneration (GBR). Thirty-two female Sprag

3. Polyurethane derived from Ricinus Communis as graft for bone defect treatments
Abstract This work evaluated polyurethane (Polyquil®) as a graft for treatment of bone defects. Bone defects of 1.5 × 0.5 cm were made in the calvaria of 16 rabbits. Eight animals had their defects treated with Polyurethane (Treated) and 8 of them had their defects filled with blood clot (Control). In the second experiment, segmental defects of 0.5 cm wer

4. Evaluation of photobiomodulation therapy associated with guided bone regeneration in critical size defects. In vivo study
Abstract The repair of bone defects raises the interest of investigators in several health specialties. Grafting techniques with bone substitutes and laser therapies have been investigated to replace autogenous bone and accelerate the bone healing process. Objective To evaluate the effect of photobiomodulation therapy (PBMT) associated with guided bone rege

6. 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

7. Histometric analysis of alveolar bone regeneration with expanded polytetrafluoroethylene (e-PTFE) and latex membranes
AIM: To investigate the amount of connective tissue migrated into the extraction socket using EPTFE and latex membranes. METHODS: Seventeen rats were selected and randomly divided into 3 groups: e-PTFE membrane (n = 6), Latex membrane (n = 6) and Control (no membrane, n=5). After extraction of the maxillary right incisor, the animals of the test groups were

8. Root Reconstructed with Mineral Trioxide Aggregate and Guided Tissue Regeneration in Apical Surgery: A 5-year Follow-up
A cirurgia apical deve ser considerada como a última opção de tratamento, e realizada quando o tratamento endodôntico convencional não proporciona o resultado esperado. Em dentes submetidos à cirurgia apical, o tipo de material retro-obturador é um dos fatores que interferem no reparo dos tecidos periapicais. O material em íntimo contato com os tecid

9. Treatment of Intrabony Defects with Anorganic Bone Matrix/P-15 or Guided Tissue Regeneration in Patients with Aggressive Periodontitis
Defeitos periodontais infra-ósseos representam um desafio particular no tratamento, especialmente em pacientes com periodontite agressiva generalizada (PAg-G). Procedimentos regenerativos tem sido indicados para esta situação clínica. O objetivo deste estudo foi comparar os resultados do tratamento de defeitos periodontais infra-ósseos com associação

10. Combined therapy with mineral trioxide aggregate, and guided tissue regeneration for a large radicular cyst: a 13-year follow-up
Biomaterials such as membrane barriers and/or bone grafts are often used to enhance periapical new bone formation. A combination of apical surgery and these biomaterials is one of the latest treatment options for avoiding tooth extraction. In case of periapical lesions, guided tissue regeneration (GTR) is attempted to improve the self-regenerative healing pr

11. Mecanismos envolvidos na resposta imune e inflamatória frente à implantação de membrana de cortical óssea bovina no tecido subcutâneo de camundongos: caracterização histomorfométrica, imunoenzimática e molecular / Mechanisms involved in immune and inflammatory response to implantation of bovine bone cortical membrane in subcutaneous tissue of mice: characterization histomorphometric, imunoenzimatic and molecular
Advances related to the biomaterials science and tissue engineering seek to clarify the mechanisms involved in the biological response associated with the use of those devices and their interaction with the immune system. This study evaluated the inflammatory and immune response developed in mice after implantation bovine bone cortical membrane in subcutaneo

12. Platelet-rich plasma in the treatment of Class II furcation defects: a histometrical study in dogs
OBJECTIVE: This study was designed to evaluate the potential adjunctive benefits of platelet-rich plasma (PRP) when used with guided-tissue regeneration (GTR) and bioactive glass (BG) in the treatment of Class II furcation lesions. MATERIAL AND METHODS: Bilateral Class II furcation lesions were surgically created and allowed to become chronic in the mandibul
