The aim of this non-randomized controlled clinical trial was to evaluate the oral health-related quality of life and masticatory efficiency of patients rehabilitated with mandibular two-implant overdentures with immediate loading or conventional dentures. Fifty completely edentulous patients wearing bimaxillary conventional dentures, for at least one year, were recruited. The patients were then...

Wear is an important issue in hip implants. Excessive wear can lead to toxicity and other implant associated medical issues such as patient discomfort and decreased mobility. Since implant wear is the result of contact between surfaces of femoral head and acetabulum implant, it is important to establish a model that can address implant surface roughness interaction. A statistical contact model ...

PURPOSE The present study introduced the application of cytodetachment technology--the examination of single cell responses to implant material surfaces--to the analysis of implant surfaces with a view to significantly improving upon conventional methods of studying cell interactions with implant surfaces. MATERIALS AND METHODS With the new cytodetachment technology, osteoblasts (MG-63) were ...

OBJECTIVE To document oral language proficiency in a group of prelingually deaf bilingual children with a cochlear implant. DESIGN Using a repeated-measures paradigm, oral language skills in the first and second language were evaluated at 2 yearly intervals after implantation. Language data were compared with normative data from children with normal hearing. SUBJECTS Twelve deaf children be...

STUDY OBJECTIVE To compare oral and implanted oestrogens for their effects in preventing postmenopausal osteoporosis. DESIGN Non-randomised cohort study of postmenopausal women treated with oral or depot oestrogens and postmenopausal controls. SETTING Gynaecological endocrine clinic in tertiary referral centre. PATIENTS Oral treatment group of 37 postmenopausal women (mean age 57.5 years,...

BACKGROUND To assess the influence of the crestal or subcrestal placement of implants upon peri-implant bone loss over 12 months of follow-up. MATERIAL AND METHODS Twenty-six patients with a single hopeless tooth were recruited in the Oral Surgery Unit (Valencia University, Valencia, Spain). The patients were randomized into two treatment groups: group A (implants placed at crestal level) or ...

Background: In the past few years, the occurrence of an oral lesion, called osteonecrosis of the jaw (ONJ), has been increasingly reported in patients undergoing treatment with bisphosphonates (BPs); however, few published histological studies of ONJ can be found in the literature. Purpose: The aim of the present case was to report an occurrence of ONJ after implant insertion. Materials and Met...

OBJECTIVES The aim of this study was to compare microbiological, histological, and mechanical findings from tissues around osseointergrated dental implants in patients who had undergone tumour resection and subsequent bone grafting with non bone grafted patients without a history of oral cancer and to develop an effective tool for the monitoring of the peri-implant tissues. A third aim was to a...

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...
