1. Mechanical and histological evaluation of a titanium device for orthodontic anchorage, placed with or without cyanoacrylate adhesive
RESUMO Objetivos: este estudo teve como objetivo realizar uma avaliação histológica de um mini-implante para ancoragem em Ortodontia. Avaliou-se, também, a carga de cisalhamento e o padrão de fratura imediatamente e após 30 e 60 dias da sua inserção, com ou sem o uso do adesivo N-butil-2-cianoacrilato. Métodos: noventa e seis mini-implantes (Arro

2. Contact phenomena modeling in biological structures on the example of the implant-bone
Abstract The work presents modeling of interface phenomena in biological structures. Selected ways of numerical modeling of phenomena at the boundary of two materials by means of FEM methods are discussed. The work focuses on phenomena related to biological structures and their mutual interactions. Using an example of an implant-bone system, various techniqu

3. Effect of Different Doses of Synthetic Parathyroid Hormone (1-34) on Bone around Implants: a Preclinical Rat Model
Resumo O objetivo deste estudo foi avaliar o efeito de uma menor dose de PTH (1-34) sobre o potencial osteogênico da cicatrização óssea ao redor de implantes de titânio inseridos na tíbia de ratos. Um estudo paralelo cego foi conduzido em 45 ratos Wistar machos adultos. Cada rato recebeu um implante de titânio (4,5 x 2,2 mm) e foi aleatoriamente desig

4. Human Embryonic Stem Cell-Derived Mesenchymal Progenitor (hESCs-MP) Growth on Nanostructured Ti6Al4V Surfaces
Nanotexturing processes that focus on enhancing the bone-implant contact, such as electropolishing, have been proposed. The aim of this work was to evaluate the influence of Ti6Al4V surface morphology on human embryonic stem cell-derived mesenchymal progenitor (hESCs-MP) growth. Three surface treatments were used in this study: mechanically polished samples

5. Efectos de tratamientos térmicos post-alcalinos sobre las propiedades superficiales de titanio para implantes dentales con diferentes recubrimientos
ABSTRACT Titanium is widely used as dental implant since it is bio-inert and osseointegratable. However, provided that this material cannot induce bone growth from its surface, it is usual to carry out different surface treatments in order to develop bioactive coatings that increase both the initial rate of bone development and the biological anchorage of im

6. 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

7. 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

8. Peri-implant assessment via cone beam computed tomography and digital periapical radiography: an ex vivo study
OBJECTIVES: This research evaluated detail registration in peri-implant bone using two different cone beam computer tomography systems and a digital periapical radiograph. METHODS: Three different image acquisition protocols were established for each cone beam computer tomography apparatus, and three clinical situations were simulated in an ex vivo fresh p

9. Osseointegration aspects of placed implant in bone reconstruction with newly developed block-type interconnected porous calcium hydroxyapatite
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 hydroxyapatite (IP-CHA). Material and Methods The IP-

10. 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

11. Investigation of the influence of design details on short implant biomechanics using colorimetric photoelastic analysis: a pilot study
Introduction : The clinical survival of a dental implant is directly related to its biomechanical behavior. Since short implants present lower bone/implant contact area, their design may be more critical to stress distribution to surrounding tissues. Photoelastic analysis is a biomechanical method that uses either simple qualitative results or complex calcul

12. Effect of chronic stress on implant osseointegration into rat's mandible
PURPOSE:To compare chronic physical stressed with normal tense animals regarding implant osseointegration in the rat mandible.METHODS:Thirty six Wistar rats were anesthesiaded and blunt instruments were used to expose and empty their alveolar inferior nerve. One implant (2.2 x 4mm) was installed into the mandibular canal. Following 72 hours, all rats were eq
