The present study evaluates the effects of occlusal loading on an implant-supported dental implant with external hexagon implant-abutment systems, using finite element method analysis. Tensile analyses were performed to simulate different axial and obliquous masticatory loads. influence variations in contouring conditions interfaces was analyzed weigh osseointegration linear non-linear cases, b...

Though totally implant-supported restorations are very successful, dentists may resort to prescribe implant overdentures because of functional, anatomical, economical or aesthetic considerations. However, the loading conditions of the partially implant-supported overdenture may affect the long term predictability of this type of restoration. The concept of the Andrew's bar system can be utilize...

OBJECTIVES Clinical studies to assess dental implants are common in implantology, but such studies are usually performed for specific indications and following a specific protocol with strict inclusion and exclusion criteria. The aim of the current study was to evaluate the Straumann Bone Level SLActive dental implant in a prospective, multicenter, noninterventional trial. METHOD AND MATERIAL...

background. the present study was undertaken to evaluate the level, sources and quality of information on implant treatment as an option for replacement of missing teeth, among a selected sample of dental patients in kerman, iran. methods. a cross-sectional study was conducted on 305 subjects who attended the 6 main dental clinics in kerman, iran during january and february 2014. a standardized...

The present work is a revision of the processes occurring in osseointegration of titanium dental implants according to different types of surfaces -namely, polished surfaces, rough surfaces obtained from subtraction methods, as well as the new hydroxyapatite biomimetic surfaces obtained from thermochemical processes. Hydroxyapatite's high plasma-projection temperatures have proven to prevent th...

BACKGROUND Implants may be placed penetrating the oral mucosa (1-stage procedure) or can be completely buried under the oral mucosa (2-stage procedure) during the healing phase of the bone at the implant surface. With a 2-stage procedure the risk of having unwanted loading onto the implants is minimized, but a second minor surgical intervention is needed to connect the healing abutments and mor...

OBJECTIVE Several theories have been presented to explain initial and secondary marginal bone loss around dental implants (e.g. microbial load, adverse loading, microbial leakage, compromised healing/adaptation of host-implant interface). MATERIAL AND METHODS This study compared the long-term outcome (up to 12 years) of sleeping with loaded implants in the mandible via a split-mouth concept. ...

Dental implants are now considered as a predictable treatment modality for the oral rehabilitation of partially or fully edentulous patients. Recently emphasis has changed towards achieving a predictable esthetic success. Creating aesthetically successful implant-supported restoration in the anterior region of oral cavity depends on the presence of interimplant papilla when multiple implants ar...

Implant failure has been associated with factors such as poor bone quality, insufficient bone volume, implant instability, unfavorable implant loading, and smoking habits. Infections and host responses may also be important factors in dental implant failure. The objectives of the present study were to identify various explanatory factors associated with titanium implant failure. Forty subjects ...
