Cranial bone regeneration with collagen type I and polyvinylpyrrolidone (Fibroquel®) combined with hyaluronic acid in Wistar rats: morphological study

Int. j. morphol; 39 (3), 2021
SUMMARY: The purpose of this study was to evaluate by morphological methods, if a mixture of Fibroquel® and hyaluronic acid implanted in an animal model of cranial bone injury could promote bone regeneration. 12 Wistar rats were divided in three groups, control group, bone injury without treatment and b...

Biocompatibilidade do gel de quitosana associado ao glicerol fosfato na reparação de defeitos ósseos induzidos experimentalmente no rádio de coelhos (Oryctolagus cuniculus)

A engenharia de tecidos caracteriza-se como ciência interdisciplinar, a qual vem desenvolvendo biomateriais para a regeneração do tecido ósseo no âmbito das medicinas humana e veterinária. O objetivo desta pesquisa foi avaliar a regeneração óssea obtida da aplicação do hidrogel de quitosana as...

Uso da associação entre hidroxiapatita e plasma rico em plaqueta no tratamento de uma não união óssea de rádio e ulna em um cão - relato de caso

A não união óssea é uma complicação ortopédica que ocorre normalmente devido à instabilidade da fratura em decorrência de uma escolha de fixação inadequada ou inapropriada, suprimento sanguíneo deficiente, osteomielite e afastamento excessivo dos fragmentos; sendo mais comumente em cães de r...

Effect of alendronate on healing of bone defect and gingival tissue in osteopenic rats

Int. j. morphol; 38 (3), 2020
The aim was to evaluate bone repair and gingival tissue repair in osteopenic rats. Fifteen female wistar rats were included; in all of them ovariectomy was realized to induce osteopenia; after 45 days, the animals were submitted to 2 surgical techinques 1) dental extraction of the upper central incisor w...

Influencia de rhBMP-2 en la reparación ósea de defectos críticos con diferentes biomateriales

Int. j. morphol; 38 (2), 2020
La regeneración de defectos óseos críticos requiere la utilización de biomateriales óseos. Así, se han utilizados agentes osteogénicos como la proteína morfogenética (rhBMP-2). El objetivo fue describir la formación ósea de defectos óseos críticos en calota de ratas utilizando rhBMP-2 con di...

Cyclosporine A impairs bone repair in critical defects filled with different osteoconductive bone substitutes

Abstract The aim of this study was to assess the influence of cyclosporine administration on the repair of critical-sized calvaria defects (CSDs) in rat calvaria filled with diverse biomaterials. Sixty animals were divided into two groups: the control (CTR) group (saline solution) and the cyclosporine (C...

Local effect of simvastatin combined with different osteoconductive biomaterials and collagen sponge on new bone formation in critical defects in rat calvaria

Acta cir. bras; 35 (1), 2020
Abstract Purpose To evaluate the local effect of simvastatin (SVT) combined with deproteinized bovine bone (DBB) with hydroxyapatite/β-tricalcium phosphate biphasic ceramics (HA/TCP) and with collagen sponge (CS) on bone repair in critical size defects (CSDs) in rat calvaria. Methods Forty-two 5-m...

Effects of NSAIDs and environmental oxygen pressure on bone regeneration

J. oral res. (Impresa); 8 (2), 2019
Objective: To evaluate the effects of administering diclofenac and ketoprofen, as well as the effects of environmental oxygen pressure variation on mandibular bone regeneration. Methods: Thirty-six guinea pigs were distributed into two equal groups. Mandibular bone defects were performed on both groups. ...
