1. On Estimation of Adhesive Strength of Implants Bioactive Coating with Titanium by Density Functional Theory and Molecular Dynamics Simulations
One of the ways to improve and accelerate osseointegration of a surgical implant with bone is application of biocompatible coatings, in particular, hydroxyapatite (HAp). Since the cases of delamination of the coating take place in dental practice, it is very important to estimate the adhesive strength of HAp with the implant. A measure of the coating-to-subs

2. Can implant surfaces affect implant stability during osseointegration? A randomized clinical trial
Abstract This randomized clinical trial evaluated the insertion torque (IT), primary, and secondary stability of dental implants with different surface treatments during the osseointegration period. Nineteen patients with bilateral partial edentulism in the posterior mandibular region were randomly allocated to two implant brand groups and received implants

3. 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

4. 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
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 administered glucocorticoids to induce osteoporosis, follo

5. Fibroblast and pre-osteoblast cell adhesive behavior on titanium alloy coated with diamond film
It is well known that titanium alloys have mechanical strengths comparable to steels, as well as high corrosion resistance. Also, they have the advantage of promoting osseointegration, when used in medical and dental implants. This work aims to describe the adhesion properties of fibroblast and osteoblast cells on the surface of titanium aluminum vanadium al

6. 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

7. Early osseointegration driven by the surface chemistry and wettability of dental implants
Objective The objective of this study was to investigate the impact of two different commercially available dental implants on osseointegration. The surfaces were sandblasting and acid etching (Group 1) and sandblasting and acid etching, then maintained in an isotonic solution of 0.9% sodium chloride (Group 2). Material and Methods X-ray photoelectron spect

8. Bone tissue response to plasma-nitrided titanium implant surfaces
A current goal of dental implant research is the development of titanium (Ti) surfaces to improve osseointegration. Plasma nitriding treatments generate surfaces that favor osteoblast differentiation, a key event to the process of osteogenesis. Based on this, it is possible to hypothesize that plasma-nitrided Ti implants may positively impact osseointegratio

9. In-vivo bone response to titanium screw implants anodized in sodium sulfate
PURPOSE: To evaluate the early bone response to a nanotextured dental implant treated with sodium sulfate (Na2SO4), using a rabbit model. METHODS: Twelve animals were randomly divided into group 1 (Control) - machined implants and group 2 (Test) - nanotextured implants. Extra-oral incision was performed to provide access to intended surgical site where the

10. Experimental study on penetration of dental implants into the maxillary sinus in different depths
The exposing of dental implant into the maxillary sinus combined with membrane perforation might increase risks of implant failure and sinus complications. Objective: The purpose of this study was to investigate the effects of the dental implant penetration into the maxillary sinus cavity in different depths on osseointegration and sinus health in a dog mo

11. Microtopografia de implantes de titânio com diferentes tratamentos de superfícies à microscopia eletrônica de varredura e de força atômica / Microtopography of titanium implants with different surface treatments scanning in electronic microscopy and atomic force microscopy
Introduction: Bone-implant interface quality may be influenced by surface roughness and determines how cells interact, cling to and fix to, therefore can enhance and shorten the time for osseointegration. This study aims to analyze qualitatively the topography and architecture of different dental implants surfaces, to compare and describe them. MATERIALS AND

12. Avaliação radiográfica dos efeitos da carga oclusal excessiva sobre implantes dentários SLA e SLActive restaurados precocemente: estudo experimental em cães / Radiographic evaluation of the effects of an excessive oclusal load on early restored SLA and SLAactive dental implants: an experimental study in dogs
O objetivo deste estudo foi avaliar os resultados radiográficos obtidos pelas analises de subtração radiográfica digital e linear de implantes dentários com superfície SLA e SLActive submetidos a carga funcional e sobrecarga oclusal precoce restaurados com reconstruções em cantilever (pôntico suspenso). Cinco cães beagle tiveram seus pré-molares m
