Efeitos da ativação do PPAR gama no reparo ósseo e na osseointegração de implantes dentários

Os receptores ativados por proliferadores de peroxissoma de isoforma gama (PPARgama) são fatores de transcrição que se encontram no entrelaçamento de várias vias metabólicas e determinam a gênese da obesidade e doenças associadas. Estudos recentes têm relatado o potencial dos medicamentos agonis...

Análise microtomografica e imunoistoquímica do osso peri-implantar em dimorfismo sexual com implantes funcionalizados com estrôncio

O presente trabalho tem por objetivo caracterizar a influência de esteróides gonadais e o dimorfismo sexual na microarquitetura do tecido ósseo formado ao redor de implantes funcionalizados por estrôncio e instalados na tíbia de ratos e ratas que foram divididos em 4 grupos experimentais. Os grupos ...

Effects of restraint stress and high-fat diet on osseointegration of titanium implants: an experimental study

Abstract This study aimed to investigate the effects of chronic restraint stress (RS) and a high-fat diet (HFD) on the osseointegration of titanium implants in a rat model. After the surgical insertion of titanium implants into the metaphysis of the tibial bone, the rats were randomly divided into four e...

Biomechanical and morphological changes produced by ionizing radiation on bone tissue surrounding dental implant

J. appl. oral sci; 28 (), 2020
Abstract Objective: This study analyzed the effect of ionizing radiation on bone microarchitecture and biomechanical properties in the bone tissue surrounding a dental implant. Methodology: Twenty rabbits received three dental morse taper junction implants: one in the left tibia and two in the right ti...

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...

Ultrastructural analysis of bone formation around dental implants in nondiabetic rats, severe diabetics not controlled and controlled with insulin

Acta cir. bras; 35 (11), 2020
Abstract Purpose: To evaluate bone formation through ultrastructural analysis around titanium implants in severe alloxanic uncontrolled diabetic rats, and controlled with insulin, in comparison with nondiabetic rats. Methods: Thirty-six male Wistar rats, weighing between 200 and 300 g, divided into thr...

Consideraciones para la colocación de implantes dentales en pacientes con osteosclerosis idiopática. Una revisión de la literatura

Rev. cient. odontol; 7 (2), 2019
Esta investigación realizó una revisión sobre la colocación de implantes dentales en pacientes con osteoesclerosis idiopática, para lo cual algunos investigadores proponen que se debe tener en cuenta un protocolo específico, el cual habla de un fresado con irrigación externa con suero fisiológico...

Comparison of subcutaneous inflammatory response to commercial and engineered zinc hydroxyapatite implants in rabbits

Hydroxyapatite (HA) is widely used as a biomaterial for bone repair and metallic prostheses coating. The main limitations of the current commercial synthetic hydroxyapatite compounds include high cost and decreased availability, especially for veterinary medicine purposes. Additionally, it is thought tha...

Sinus floor elevation using a new bovine bone grafting material: case report and bone grafting materials update

Actual. osteol; 15 (3), 2019
Bone grafting is important to preserve the alveolar bone ridge height and volume for dental implant placement. Even though implant-supported overdentures present highly successful outcomes, it seems that a great number of edentulous individuals have not pursued implant-based rehabilitation. The cost of t...
