1. Impact of micronutrients supplementation on bone repair around implants: microCT and counter-torque analysis in rats
ABSTRACT The use of natural substances and micronutritional approaches has been suggested as a therapeutic alternative to benefit the bone healing associated with no side effects. Nevertheless, the influence of micronutritional interventions with therapeutic proprieties on the bone repair has yet to be intensely evaluated, and no evidence is available explor

2. Estudo histológico dos tecidos conjuntivo e osteóide em enxertos ósseos com polímero de mamona : estudo experimental em ratos / Histological study of connective and osteoid tissue in bone grafts with castor oil polymer : experimental study in rats
The reconstruction of great bone loss defects represents a challenge for reconstructive surgery. To reconstruct these defects it is necessary to create conditions to stimulate new bone formation, in order to block the connective healing tissue growth towards the bony defect, which blocks the osteogenesis. The autogenous grafts are inconvenient, because they

3. Análise quantitativa do corante azul de Evan extravasado do interior das câmaras internas dos implantes por suas interfaces protéticas nas condições: Hexágono Externo (HE) - Hexágono Interno (HI) - Cone Morse (CM) / Quantitative analysis of Evans blue dye leakage from internal implant chambers through their prosthetic interfaces under the following conditions: External Hexagon (HE) Internal Hexagon (IH) Morse Cone (MC)
Research and studies seek to evaluate the capacity of adaptation and sealing between the implant-intermediate connections of different dental implant systems. It has recently been observed that in implants with screw-retained abutments, various phenomena, such as screw4 loosening and fracture, rotation and fracture of the abutment with bacterial penetration

4. 3d analysis of stress distribuition on bar/clips structure and bone implant interface due to bar material and vertical misfit to dental implant / Analise tridimensional da distribuição de tensões na estrutura do sistema barra/clips e interface osso/implante em função do tipo de material da barra e do desajuste vertical aos implantes
Este trabalho verificou tridimensionalmente a distribuição de tensões na estrutura e interface osso/implante do sistema barra/clips sobre dois implantes osseointegrados quando influenciada pelo tipo de material da barra (Liga de Au tipo III, liga de AgPd, liga de CoCr e Ti cp) e por diferentes níveis de desajuste vertical da barra a um dos implantes (5Xm

5. Efeito do tipo de revestimento estetico e da eletroerosão sobre a desadaptação de infra-estruturas implanto-suportadas fundidas em titanio c.p / The influence of the veneering application and Spark erosion on the misfit level of implant-supported frameworks
The demand for a passive fit of frameworks for osseointegrated endousseous implants abutments is well known, because the tightening of an inaccurate framework to the abutments can transmit stress to the bone-metal interface. The purpose of the present study was to evaluate the influence of the veneering application and porcelain firing cycle on the misfit le

6. Efeito do tipo de revestimento estetico e da eletroerosão sobre a desadaptação de infra-estruturas metalicas implantossuportadas / Influence of vennering material and spark erosion on marginal misfit of implant-suported frameworks
The demand for a passive fit of frameworks for osseointegrated endousseous implants abutments is well known, because the tightening of an inaccurate framework to the abutments can transmit stress to the bone-metal interface. The purpose of the present study was to evaluate the influence of the veneering application and porcelain firing cycle on the misfit le

7. Ensaios mecânicos e estudo histológico da interface dos implantes vertebrais / Mechanical and histological studies of the vertebral screw interface
Spine surgery has developed a lot in the last years because of the evolution of the fixation system. The behavior of a screw in the bone is still unknown in many ways. Because the screw is the anchor of sustentation, this work tries to find the answers involving the pedicle screw fixation. To reach this objective we developed this work based on mechanical an

8. A study of the correlation between marginal fit and tensions transmitted to implants by one-piece metal castings - a photoelastic analysis. / Estudo da correlação entre adaptação marginal e tensões transmitidas aos implantes por estruturas metálicas fundidas em monobloco - análise fotoelástica.
Obtaining a good marginal fit of the prosthetic components is one of the main obstacles to the success of rehabilitation with implant-supported prostheses. It is not clear, in the literature, which misfit levels are considered clinically acceptable, but it is known that the absence of a perfect and passive fit may cause inadequate tensions on the osseointegr

9. Estudo da Participação do Osso Cortical e Esponjoso na Fixação de Implante Pedicular na Coluna Lombar. / Mechanical and histological studies of the vertebral screw interface
Foi realizado estudo experimental com a finalidade de avaliar a participação do osso cortical e osso esponjoso dos pedículos vertebrais, na fixação dos parafusos pediculares. Foram utilizados 10 segmentos de coluna lombar de adultos, retirados durante autópsia. O diâmetro dos pedículos das vértebras de L1 a L5 foram avaliados, considerando o diâmet
