Introdouction: Although highly desirable outcomes and longterm survival of dental implant treatments are well documented, implant failures still occur due to various reasons. Several risk factors may impair implant survival including implant dimensions (length, diameter, and implant design), procedures, local bone density at the implant site, and patient-related risk factors such as age, smokin...
Since the introduction of modern dental implants in the 1980s, the number of inserted implants has steadily increased. Implant systems have become more sophisticated and have enormously enhanced patients' quality of life. Although there has been tremendous development in implant materials and clinical methods, bacterial infections are still one of the major causes of implant failure. These infe...
Introduction. The differences in the supporting structure of the implant make them more susceptible to inflammation and bone loss when plaque accumulates as compared to the teeth. Therefore, a comprehensive maintenance protocol should be followed to ensure the longevity of the implant. Material and Method. A research to provide scientific evidence supporting the feasibility of various implant c...
Introduction: Surface roughness can increase the retention of castings by ridges and grooves that are microretentive. This study compared the retention of implant-supported crowns when used with 3 different surface roughness abutments and one temporary cement. Methods: Thirty solid abutments (ITI), 4 mm high, were divided into three groups randomly. In the first group, 10 abutments were roughen...
background and aims. resonance frequency analysis (rfa) offers a noninvasive clinical measurement of stability and osseointegration of implants; it is a useful tool to establish implant loading time. the rfa values are represented by a quantitative unit called the implant stability quotient (isq) on a scale from 1 to 100. the aim of the present study was to measure the stability of astra tech a...
UNLABELLED Although the clinical term "osseointegration" describes the anchorage of endosseous implants to withstand functional loading, it provides no insight into the mechanisms of bony healing around such implants. Nevertheless, an understanding of the sequence of bone healing events around endosseous implants is believed to be critical in developing biologic design criteria for implant surf...
Background and Objective: Nowadays, various biomaterials have been presented for regeneration of osseous defects and Bio-oss is one of them. The objective of this study was evaluation of Bio-oss function in intramedullary space of rabbit`s tibia near titanium implant. Materials and Methods: In this study, 12 white New Zealand rabbits were selected and randomly divided into control and experimen...
Background and Objectives: The success rates of dental implants have been reported as a challenge, especially for early loading in the posterior maxilla area. surfaces are generally modified an attempt to improve osseointegration. In which Unitite with Nano hydroxyapatite coating affect healing process acceleration, high hydrophilicity, increased bone formation (BIC - Bone Implant Contact ), qu...
PURPOSE Patient-reported outcomes are increasingly commonly used as a method of evaluating treatments. This cross-sectional study aimed to evaluate implant treatment from the perspective of patient-reported outcomes. MATERIALS AND METHODS Subjects were 804 patients who visited the Department of Oral Implantology at Osaka Dental University. The participants were categorized into a pre-implant ...
