BACKGROUND A sufficient amount of bone is essential to ensure long-term stability of dental implants. To support the bone regeneration process, different techniques and materials are available. It has been questioned whether these techniques and materials may compromise implant survival compared to pristine bone. To properly answer this question, long-term stability up to 20.2 years after inser...

PURPOSE The aim of this systematic review is to address treatment outcomes of Mandibular implant overdentures relative to implant survival rate, maintenance and complications, and patient satisfaction. MATERIALS AND METHODS A systematic literature search was conducted by a PubMed search strategy and hand-searching of relevant journals from included studies. Randomized Clinical Trials (RCT) an...

PURPOSE To report on the effect of immediate implant loading with fixed prostheses compared to early and conventional loading on implant and prosthesis survival, failure, and complications. MATERIALS AND METHODS An electronic and manual search was conducted to identify randomized controlled clinical trials (RCTs) as well as prospective and retrospective studies involving rough surface implant...

PURPOSE To compare dental implant survival rates when placed in native bone and grafted sites. Additionally, risk factors associated with dental implant loss were identified. This study was based on the hypothesis that bone grafting has no effect on implant survival rates. MATERIALS AND METHODS A retrospective chart review was conducted for patients receiving dental implants at the University...

objectives : anterior maxilla, known as the esthetic zone, plays an important role in facial and smile esthetics. this study assessed the frequency of implant treatments in the esthetic zone of patients presenting to dental implant department of tehran university during 2002-2012. materials and methods: this descriptive study was conducted on dental records of patients receiving implant treatme...

A prospective randomized study was conducted to determine if a design change in the articular surface geometry introduced in the Optetrak total knee to increase prosthetic joint conformity and further reduce polyethylene stress had any impact on implant survival, particularly when the all-polyethylene version of the implant was used. Forty-seven patients undergoing bilateral simultaneous total ...

objectives: the purpose of this study was to compare the outcomes of immediate and delayed rehabilitation of edentulous jaws by means of two straight and two tilted implants after one year of function. materials and methods: thirty consecutive patients (16 males, 14 females) were enrolled in this study. two anterior straight and two posterior tilted implants were placed in each patient. accordi...

PURPOSE This study retrospectively evaluated implant survival of 631 osseointegrated implants installed in irradiated cancer patients over a 25-year period. PATIENTS AND METHODS The files of 107 patients followed since 1979 were evaluated. Factors influencing implant survival as oncologic treatment, radiotherapy protocols, patient and implant related elements were analyzed. RESULTS Compared...

BACKGROUND Dental implants have become the most viable option for rehabilitation. Although, many studies report the success of these reconstructions using implants, a cumulative data about the various studies and the failure rate still remain unaddressed. Therefore, the purpose of this systematic review was to analyze these data and to derive the cumulative survival rate of different implant-su...

This study examined endosseous cylinder implant survival, defined as the unqualified presence of the implant in the mouth at the end of the observation period, in 598 consecutive VA patients, with a total of 2098 implants. Data were taken from the Department of Veterans Affairs (VA) Dental Implant Registry, which has maintained longitudinal data on the survival of individual dental implants in ...
