Abstract This study analyzed the effects of implant design factors (diameter, length, and connection type) bone quality on long-term success implantation via finite element (FE) analysis, considering remodeling process. A total 36 cases three-dimensional FE model, with an complex located in mandibular section molar region, were considered. An analysis dental was implemented Abaqus UMAT subrouti...

PURPOSE The aim of this article was to review the current literature with regard to survival and success rates, along with the clinical procedures and outcomes associated with immediate and delayed implant placement. MATERIALS AND METHODS A MEDLINE search was conducted of studies published between 1990 and June 2003. Randomized and nonrandomized clinical trials, cohort studies, case-control s...

there has been a lot of development in the science of implantology since forty years ago when extensive research began on this field of science. the use of dental implantology has also increased in the last decade, which the main reason is the success of it. recently some of our colleagues participate in short time introductory and advanced courses of implant inside or outside the country and b...

OBJECTIVE The purpose of this study was to determine the efficacy of bone cement-augmented short segment fixation using percutaneous screws for thoracolumbar burst fractures in a background of severe osteoporosis. METHODS Sixteen patients with a single-level thoracolumbar burst fracture (T11-L2) accompanying severe osteoporosis treated from January 2008 to November 2009 were prospectively ana...

PURPOSE The aim of this study was to analyze the short-term predictability and reliability of Astra Tech implants according to the demographical distribution of patients and condition of implant sites and location of implants. METHODS Among patients treated with Astra Tech implant (Astra Tech AB) in the Department of Periodontology at the Dental Hospital of Yonsei University of College of Den...

BACKGROUND Osseointegrated implants are a suitable alternative for prosthetic attachment in individuals with a transfemoral amputation, who are unable to wear a socket. However, the small bone-implant contact area, reduced muscular leverage, and osteoporosis contraindicate osseointegrated implant use in transfemoral amputees with osteoporosis and a short residuum. We report on the feasibility o...

BACKGROUND To quantitatively compare short-term hard exudates (HEs) alteration in patients with diabetic macular edema (DME) after intravitreal triamcinolone, dexamethasone implant or bevacizumab injections. METHODS This retrospective study enrolled DME eyes with HEs that underwent a single-dose intravitreal injection of triamcinolone (25 eyes), dexamethasone implant (20 eyes), or three month...
