background: the success of dental implants depends on the manner in which stresses are transferred to the surrounding bone. an important consideration is to design an implant with a geometry that will minimize the peak bone stresses caused by standard loading. the aim of this study was to assess the infl uence of implant thread geometry on biomechanical load transfer and to compare the differen...

The first report in the literature to quantify early crestal bone loss was a 15-year retrospective study that evaluated implants placed in edentulous jaws. In this study, Adell et al. reported an average of 1.2 mm marginal bone loss from the first thread during healing and the first year after loading. In contrast with the bone loss during the first year, there was an average of only 0.1 mm bon...

Objectives Root resorption is a dangerous side effect in orthodontics, and maxillary incisors are at the highest risk for root resorption. It is important to understand optimal force considerations for patients with altered root lengths.The purpose of this study was to investigate the effects of root length on stress distribution on roots by means of three dimensional fi...
