background: the aim of this in vitro study was to evaluate the effect of shape, diameter and length of implants on their primary stability based on resonance frequency analysis. materials and methods: replace select tapered and branemark mk iii implants were selected. each of these two selected groups was divided into nine subgroups based on the implant length (il) (short, medium and long) and ...

background: endometriosis is defined as the growth of endometrial tissues in ectopic places outside the uterus. this disease has an important effect on the health and fertility of affected women. it’s etiology is not clearly known. for better understanding the pathophysiology of this disease, many researchers study on several aspects of the disease on animals. objective: in this experimental st...

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...

objective: whilst many questions and doubts still remain, today the use of dental im-plants has gained an increasing popularity amongst patients as well as dentists. the aim of this study is to analyze the survival rate in using such implants over a 10 year period. materials and methods: in this study, 3050 iti implants placed in 1000 patients with the mean age of 49.5 years (54.4% males and 44...

objective: to determine the pattern of stability changes as a reflection of early healing around single-stage roughened-surface implants in humans utilizing resonance frequency analysis (rfa). materials and methods: hundred twenty-five patients who demanded dental implants were treated with two different implant (nobel biocare replacetm and strummantm iti) systems. bone type was classified into...

objectives: this study sought to assess the effects of length and inclination of implants on stress distribution in an implant and terminal abutment teeth in an implant assisted-removable partial denture (rpd) using three-dimensional (3d) finite element analysis (fea).   materials and methods: in this in vitro study, a 3d finite element model of a partially dentate mandible with a distal extens...

  Background and Objective: The concept of immediate occlusal loading with dental implants offers several advantages. In this research, the effect of type of restoration on Osseointegration rate of dental implants was histologically evaluated. Materials and Methods: Three months prior to implantation, the lower premolar teeth of 15 dogs were extracted. Then, 3 to 4 Maestro™ implants were plac...
