Abordaje reconstructivo para un defecto de periimplantitis
Reconstructive approach for a peri-implantitis defect

Rev. ADM; 81 (2), 2024
Si bien el conocimiento científico para el tratamiento de la periimplantitis ha avanzado significativamente en los últimos años, sigue en discusión qué tipo de abordaje quirúrgico genera los mejores resultados clínicos y si el uso de biomateriales da mejoras significativas en dicho tratamiento....

Three-dimensional printed poly (L-lactide) and hydroxyapatite composite for reconstruction of critical bone defect in rabbits

Acta cir. bras; 36 (4), 2021
ABSTRACT Purpose To use a 3D printed poly (L-lactide) acid (PLLA) and hydroxyapatite (HA) composite as a bone substitute for reconstruction of a critical bone defect in the radius of rabbits. Methods A 1.5 cm ostectomy was performed in the radial diaphysis of 60 New Zealand white rabbits. The rabbits w...

Enucleation of Odontogenic Cyst with Bone Graft

ABSTRACT: Periapical cyst originates from an inflammatory reaction in the body that occurs due to a long-term endodontic aggression. It is more prevalent in caucasian male, during the third decade of life, in the anterior portion of the maxilla. They are commonly radiographic findings, due to their asymp...

Uso de la Fibrina Rica en Plaquetas Inyectable (i-PRF) en Defectos Infra Óseos en Terapia Periodontal no Quirúrgica. Reporte de Dos Casos

RESUMEN: Entre los concentrados plaquetarios de segunda generación, ha suscitado creciente interés, el uso de fibrina rica en plaquetas y leucocitos inyectable (i-PRF); que se obtiene a partir de la centrifugación inmediata de sangre venosa del propio individuo, y que aporta concentraciones elevadas d...

Characterization of bone substitute beta946; -TCP block for maxillofacial reconstruction

Int. j. morphol; 37 (1), 2019
SUMMARY: The aim of this study was to characterize a commercial beta tricalcium phosphate (β-TCP) block allograft for use in maxillofacial reconstruction, evaluating its homogeneity, porosity and mineralization. Two commercial 5 x 5 x10 mm chronOS Vivify β-TCP blocks were used, which were evalu...

Short-term use of resveratrol in alloplastic graft material applied with calvarial bone defects in rats

Acta cir. bras; 34 (7), 2019
Abstract Purpose: The effects of resveratrol administration on calvarial bone defects with alloplastic graft material was investigated for osteoinductive reaction and bone development in rats. Methods: Healthy male rats were randomly divided into 3 groups consisting of 10 rats. Groups were as follows: ...

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 ...

Bone repair access of BoneCeramic™ in 5-mm defects: study on rat calvaria

J. appl. oral sci; 26 (), 2018
Abstract Objective: The aim of this study was to evaluate the osteoconductive potential of BoneCeramic™ on bone healing in rat calvaria 5-mm defects. Material and Methods: A 5-mm calvaria bone defect was induced in three groups and the defect was not filled with biomaterial [Clot Group (CG)], aut...

Bioactive glass added to autogenous bone graft in maxillary sinus augmentation: a prospective histomorphometric, immunohistochemical, and bone graft resorption assessment

J. appl. oral sci; 26 (), 2018
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. Mater...

Influence of β-tricalcium phosphate of different geometric shape on the morphology of regeneration of experimental defect of compact bone tissue

Actual. osteol; 13 (1), 2017
Purpose: to compare the healing process of a defect of compact bone tissue after the implantation of osteoplastic materials based on β-tricalcium phosphate (“ChronOS™” and “Calc-i-oss®”), which differ by manufacturer, geometrical shape and microscopic structure. Methods: the experiment was pe...
