Introduction: The survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. Implant success also is affected by the maintenance of the crestal bone around implants. The aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...
Background and Aims: With increasing age and inability to maintain good oral hygiene, the chances of tooth loss increase and the need for dental implants will increase in the future. It also increases the risk of developing peripheral implants, especially at older ages in the failure of implant treatments. Recently, the high prevalence of cardiovascular disease and peri-implantitis in the elder...

crestal bone loss is a biological complication in implant dentistry. the aim of this study was to compare the effect of progressive and conventional loading on crestal bone height and bone density around single osseointegrated implants in the posterior maxilla by a longitudinal radiographic assessment technique.twenty micro thread implants were placed in 10 patients (two implants per patient). ...
Background and Aim: This retrospective study aimed to investigate the effects of surface roughness and implant body design on the amount of crestal bone loss around implant. Materials and Methods: In this retrospective study, dental records of 87 patients who received 139 implants were evaluated. The ITI group received 63 implants with moderate roughness, while the DIO group received 76 implan...
statement of the problem replacement of missing or lost teeth with dental prostheses supported by dental implants has been accepted and received positive evaluations from patients who have undergone implant treatment. purpose the aim of this study was to evaluate the level of patient knowledge about dental implants among a selected sample of dental patients in tabriz, iran materials and methods...
Bone osseointegration around dental implant can cause earlier stabilization and fixation of implant and reduce healing time. Hydroxyapatite coating can affect bone osseointegration and enhance its rates. The aim of this study was comparison of osseointegration between plasma sprayed hydroxyapatite coated and uncoated dental implants in cats. Four endodontic implants including, vitallium and two...
