Effect of focal adhesion kinase inhibition on osteoblastic cells grown on titanium with different topographies

J. appl. oral sci; 28 (), 2020
Abstract Objective The present study aimed to investigate the participation of focal adhesion kinases (FAK) in interactions between osteoblastic cells and titanium (Ti) surfaces with three different topographies, namely, untreated (US), microstructured (MS), and nanostructured (NS). Methodology Osteo...

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: ...

Ganoderma lucidum, a promising agent possessing antioxidant and anti-inflammatory effects for treating calvarial defects with graft application in rats

Acta cir. bras; 34 (9), 2019
Abstract Purpose: Ganoderma lucidum, a kind of mushroom used for its antioxidant, anti-inflammatory, and immunomodulatory activities, was investigated in the present study for its possible healing effect on calvarial defects with bone grafts. Methods: Wistar male rats (n = 30) were divided into 3 group...

The effects of subcutaneous injection of nicotine on osseointegration of machined and anodized implants in rabbits

Acta cir. bras; 33 (1), 2018
Abstract Purpose: To evaluate the influence of subcutaneous injection nicotine in osseointegration process on different implant surfaces. Methods: Twenty-two male rabbits were distributed into two groups according to the subcutaneous injections: (1) nicotine 3 mg/day/kg and (2) 0.9 % NaCI 3 mL/day/kg,...

Daily melatonin administration improves osseointegration in pinealectomized rats

J. appl. oral sci; 26 (), 2018
Abstract The hypothesis of this study was that the peri-implant bone healing of the group of pinealectomized rats would differ from the control group. The samples were subjected to immunohistochemical, microtomographic (total porosity and connectivity density), and fluorochrome (mineralized surface) anal...

Effects of continual intermittent administration of parathyroid hormone on implant stability in the presence of osteoporosis: an in vivo study using resonance frequency analysis in a rabbit model

J. appl. oral sci; 25 (5), 2017
Abstract Objective: This study aimed to evaluate the effects of continual intermittent administration of parathyroid hormone (PTH) on implant stability in the presence of osteoporosis, using rabbit models. Material and Methods: Fifteen female New Zealand white rabbits underwent ovariectomy and were adm...

Short term sodium alendronate administration improves the peri-implant bone quality in osteoporotic animals

J. appl. oral sci; 25 (1), 2017
Abstract Sodium alendronate is a bisphosphonate drug that exerts antiresorptive action and is used to treat osteoporosis. Objective The aim of this study was to evaluate the bone repair process at the bone/implant interface of osteoporotic rats treated with sodium alendronate through the analysis of mi...

Osseointegration aspects of placed implant in bone reconstruction with newly developed block-type interconnected porous calcium hydroxyapatite

J. appl. oral sci; 24 (4), 2016
ABSTRACT Artificial bone has been employed to reconstruct bone defects. However, only few reports on implant placement after block bone grafting exist. Objectives The purpose of this study was to evaluate the osseointegration of dental implant in bone reconstructions with interconnected porous calcium ...

Eficacia de la Hidroxiapatita en la Cicatrización de Injertos Óseos e Implantes Dentales: una Revisión Sistemática de la Literatura

La hidroxiapatita (HA) es un componente mineral del hueso. Se ha comercializado la HA sintética o aloplástica en forma porosa o no porosa, densa y reabsorbible o no reabsorbible. Se utiliza como injerto óseo dada sus propiedades osteoconductivas y estimuladoras de proliferación celular generando así...
