1. Does traumatic occlusal forces lead to peri-implant bone loss? A systematic review
Abstract Observational studies have indicated that crestal bone level changes at implants are typically associated with clinical signs of inflammation, but still mechanical overload has been described as possible factor leading to hard–tissue deficiencies at implant sites without mucosal inflammation. The aim of this paper was systematically review the lit

2. Effects of hyperbaric oxygen treatment on implant osseointegration in experimental diabetes mellitus
Abstract Objective To evaluate whether hyperbaric oxygen (HBO) treatment has a favorable effect on implant osseointegration in diabetic rabbits. Material and Methods An experimental diabetes model was induced in 32 New Zealand rabbits through IV injection of alloxan. After the state of diabetes had been confirmed, one dental implant was placed in the met

3. Porous Titanium Associated with CaP Coating: In Vivo and In Vitro Osteogenic Performance
This in vitro and in vivo study compared different topographies of Ti samples (dense, porosity of 30% and 40%) with or not CaP coating, prepared by powder metallurgy. Osteogenic cells from newborn rat calvaria were plated onto the samples and cell adhesion (24 hours), alkaline phosphatase activity (7 and 10 days) and mineralization nodules (14 days) were ass

4. SHEEP AS AN EXPERIMENTAL MODEL FOR BIOMATERIAL IMPLANT EVALUATION
ABSTRACT Objective: Based on a literature review and on our own experience, this study proposes sheep as an experimental model to evaluate the bioactive capacity of bone substitute biomaterials, dental implant systems and orthopedics devices. The literature review covered relevant databases available on the Internet from 1990 until to date, and was suppleme

5. Functional investigation of bone implant viability using radiotracers in a new model of osteonecrosis
OBJECTIVES: Conventional imaging methods are excellent for the morphological characterization of the consequences of osteonecrosis; however, only specialized techniques have been considered useful for obtaining functional information. To explore the affinity of radiotracers for severely devascularized bone, a new mouse model of isolated femur implanted in a

6. Hormônio do crescimento no processo de osseointegração de implantes de titânio: estudo experimental e revisão de literatura / Growth hormone on the osseointegration process of titanium implants: an experimental study and review of literature
In order to accelerate and improve the quality of the osseointegration process has recently been given emphasis to growth factors. Thus, this thesis was aimed to evaluate the use of growth hormone (GH) on osseointegration of titanium implants. This thesis is composed of two papers, the first chapter is a review of literature on the use of growth factors, and

7. Evaluation of the compound of granulated Ricinus and synthetic hydroxyapatite on the osseointegration in rabbits: histological study / Avaliação do composto ósseo de Ricinus granulado e hidroxiapatita sintética na osteointegração em coelhos: estudo histológico
With the growing commitment of human and veterinary medicine in the search for biomaterials osseointegration, the histological study is present in the interpretation and presentation of results of histomorphologic interactions of materials implanted with bone tissue, providing a speed of bone formation. The proposal was evaluated by histological study the bi

8. OSTEOSSÍNTESE UMERAL EM POMBOS DOMÉSTICOS (Columba lívia) POR XENOENXERTO ÓSSEO, CONSERVADO EM MEL TRATADOS OU NÃO COM LASER ARSENETO DE GÁLIO (AsGa) / OSTEOSYNTHESIS OF THE HUMERAL IN DOMESTIC PIGEONS (Columba lívia) BY BONE XENOGRAFTS, PRESERVED IN HONEY TREATED OR NOT WITH GALLIUM ARSENIDE LASER (GaAS)
The increase in attendance of wild animals, especially birds, leads to the veterinarian deal with numerous diseases in these animals, being the fractures one of the most frequent injuries in the veterinary clinical surgery. The aim of this study was to reduce the recovery period of birds with humeral fracture in order to anticipate the release of them back i

9. Effect of different loading time on the stabililty and boné response around dental implants. Resonance frequency analysis and histomorphometric study in dogs. / Efeito de diferentes tempos de ativação sobre a estabilidade e resposta óssea ao redor de implantes dentários. Estudo por análise de freqüência de ressonância e histomorfométrico em cães
Purpose: The aim of this study was to evaluate the implant stability through frequency resonance analysis and the effect that different loading time will have on the bone response around implants through a histomorphometric analysis. Material and Methods: Three Replace Select implants were placed on each side of the mandible in 8 dogs totaling 48 implants in

10. A influência da superfície bioativa de implante na osseointegração. Estudo comparativo em cães / The effect of a biofunctionalized implant surface on the osseointegration. A histomorphometric study in dogs
Among the different surface properties that influence the bone apposition around implants, the chemical or biochemical composition may interfere in its acceptance by the surrounding bone. The aim of this study was to investigate if a biofunctionalization of implant surface influences the bone apposition in a dog model and to compare it with other surfaces, s

Avaliação macroscópica e microscópica do cimento Portland comum - CP I e do cimento Portland branco não estrutural - CPB incluídos na calvária de ratos / Macroscopic and microscopic evaluation of Portland Cement Joint - CP I and the Portland Cement White not structural - CPB included in the skull of rats
The biomaterials can be defined as substances of natural or synthetic origin that are tolerated on a temporary or permanent by the various tissues that make up the organs of living beings. Among these biomaterials can quote the mineral trioxide aggregate (MTA), which was developed at the University of Loma Linda, in the 90s. Since then, it stopped work on re

12. Compósito de hidroxiapatita e lignina como promotor de osseointegração entre implante metálico e tecido ósseo: estudo experimental / Hydroxyapatite-lignin composite as a metallic implant-bone tissue osseointegration improver: experimental study
This study aimed to evaluate the composite made of synthetic hydroxyapatite associated with lignin, as a promoter of integration between a metal implant (intra-medullar pin, Schanz) and bone tissue. Twenty New Zealand rabbits were used, each of them had both tibia operated: the left one was treated with the composite and the right was not treated, serving as
