background and aims. despite the very good results, implant treatment has also been associated with some failures. the aim of this study was to evaluate the success rate, survival rate, and tissue health indices around xive® dental implants placed in patients in a dental office in isfahan. materials and methods. in this cross-sectional study, 129 xive® dental implants were selected. a form was ...
Background and Aims: Thermal changes in the oral cavity can be transferred to the implants placed in bone and affect the prognosis of the treatments. Furthermore, some investigators proposed improvement of habitual consumption of hot or cold beverages. The aim of the present study was to measure the effect of temperature changes in the oral cavity following consumption of hot and cold drinks ...
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 jaw...
Introduction & Objective: Due to the patients’ growing interest in the use of dental implants, medical staff should be completely aware of treatment success and prognostic factors to prevent failures. The purpose of this study was to evaluate the effect of different crown to implant ratio (C / I Ratio) in the posterior areas of the maxilla and mandible as one of the most important princip...

background: titanium (ti) implants are commonly coated with hydroxyapatite (ha). however, ha has some disadvantages such as brittleness, low tensile strength and fracture toughness. it is desirable to combine the excellent mechanical properties of zro2 and the chemical inertness of al2o3 with respect to the purpose of this project which was coating ti implants with ha-zro2-al2o3 to modify the s...
results sixteen patients (66.7%) in antibiotic group and 20 patients (90.9%) in placebo group had post-operative swelling and pain. the average pain in the antibiotic and placebo groups were (31.04 + 26.29) and (37.73 + 23.69) respectively, and the difference was not statistically significant (p value = 0.37). one patient in each group had probing depth between 5 to 7 mm in six months after sur...
