Background: The hip joint is the largest joint after the knee, which gives stability to the whole human structure. The hip joint consists of a femoral head which articulates with the acetabulum. Due to age and wear between the joints, these joints need to be replaced with implants which can function just as a natural joint. Since the early 19th century, the hip joint arthroplasty has evolved, a...

Introduction: To achieve the best esthetic and functional results of implantation and patient satisfaction, different protocols of implant therapy have been recommended. Immediate implantation can provide the outcome faster than other protocols making it the treatment of choice. The rate of peri-implant bone resorption should be measured clinically and radiographically as bone support is a key ...

the anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. with the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. immediate implant placement has numerous advantages compared to the delayed procedure including superi...

PURPOSE To report on keratoectasia after laser in situ keratomileusis (LASIK) in two eyes of two patients who had no obvious preoperative risk factors, and treatment of keratoectasia by intrastromal corneal ring segments. METHOD Clinical interventional case report. RESULTS Two patients underwent LASIK in both eyes at Shinagawa LASIK center, Tokyo. Preoperative standard ophthalmological exam...

 longevity of osseointegrated implants are intensely influenced by biomechanical factors. Control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. In this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum Von Mises stress in implant-abutment complex and ja...

Introduction: The aim of this study was to determine the accuracy of digital panoramic radiography in estimating the crestal width of implant fixtures after surgery. Materials and Methods:We selected 241 digital panoramic images after implant insertion which had documented information of their actual size. The crestal width was measured on radiographs. We compared two measuring methods in diff...
