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...

the main goal of this study was to evaluate differences in stress distribution relevant to the number of implants under an anterior bridge when combined with a removable partial denture in the posterior region.four three-dimensional finite element models (3d fem) were designed from a mandible containing an implant-supported bridge extending between canines, and a bilateral distal extension remo...

introduction microbial plaque is the main etiologic factor which causes disease in soft tissue around dental implants. the purpose of this study was to evaluate the effect of plaque on health indicies of soft tissue around dental implants. methods and materials 45 patients with 211 dental implants were examined clinically for four years after prosthodontic treatment. plaque index and health ind...

Introduction: Among different non-invasive approaches for determining the stability of the implant within the bone is to use a dynamic device called Periotest®.It is designed to provide objective measurement of tooth mobility. The aim of the present study is to evaluate the stress transfer and stability in short and standard dental implants using Periotest®</sup...

background: the aim of this study is to evaluate and compare the crestal bone loss and stability of single mandibular posterior dental implants placed in immediate functional loading (ifl) and immediate nonfunctional loading (infl) during 6 months after placement. materials and methods: forty single piece root form titanium implants were placed in 20 patients using ifl and infl techniques. the ...

background and aims. the aim of this study was to evaluate the predictability of implantation at the time of maxillary and mandibular molar extraction. materials and methods. maxillary and mandibular molars were extracted with an atraumatic technique (root separation and careful extraction with a periotome) to preserve all remaining inter-radicular bone. then, 115 tapered and straight implants ...

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 placed i...

Full mouth rehabilitation with fixed implant supported prostheses is one of the challenging treatments, because important factors in aesthetic and function should be considered. Implants' alignments and locations should be planned before the insertion unless the improper inclination and location of implants would lead to difficulties in patient's comfort, oral hygiene problem and inability to r...

o bjective : increased levels of oxidative stress markers in periodontitis have been reported by recent studies. malondialdehyde (mda) and superoxide dismutase (sod) are both in- creased during oxidative stress. the aim of this study was to detect and measure the level of oxidative stress markers in peri-implant crevicular fluid (picf). their correlation with peri-implant clinical parameters wa...
