Purpose: The purpose of this study was to identify the important parameters for a model-based design optimization method through comparison of different biomechanical environments and various dental implant models. Materials and Methods: Finite element analysis (FEA) was applied to model a mandibular bone implant system. Essential parameters, such as, cortical bone properties, boundary conditio...

Posterior single-tooth implant restorations are subjected to an increased risk of bending overload. A high incidence of implant fracture has been reported when using a single standard 3.75-mm-diameter implant to support a molar restoration. The purpose of this article is to demonstrate the clinical feasibility of placing two implants to support a molar restoration and to compare this treatment ...

The biological interaction between the jaw bones and dental implant is fundamental for the long-term success of dental implant placement. Nevertheless, the insufficient bone volume remains a major clinical problem, especially in case of immediate dental implant. Using a canine model, the present study proves the regenerative potential of adipose- derived stem cells (ADSCs) to repair peri-implan...

i ntroduction: bisphosphonates are  widely used  for  various bone  diseases including osteoporosis and bone tumors. one of the complications associated with these pharmaceutical agents is bisphosphonate-related osteonecrosis of the jaw. this condition may be triggered by placement of dental implants. in turn,  osteonecrosis  of  the  jaw  may  cause  failure  in  osseointegration  of implants....

PURPOSE The purpose of this study was to assess the survival rates and interproximal bone levels for Osseotite implants that were restored with fixed provisional crowns without occlusion immediately after implant placement. MATERIALS AND METHODS Ninety-three implants were placed in 38 partially edentulous patients. All implants were immediately restored with prefabricated abutments and cement...

AIM To test whether or not the use of short dental implants (6 mm) results in an implant survival rate similar to long implants (11-15 mm) in combination with sinus grafting. METHODS This multicentre study enrolled 101 patients with a posterior maxillary bone height of 5-7 mm. Patients randomly received short implants (6 mm) (group short) or long implants (11-15 mm) with sinus grafting (group g...

soft tissue-implant interface is an important anatomical feature contributing to the long-term success of dental implants. based on the available evidence, different factors may influence biological width around implants including the surgical technique, implant loading, implant surface properties, abutment materials, implant position, and width of the peri-implant mucosa. the purpose of the pr...

BACKGROUND Three-dimensional finite element analysis (FEA) is effective in analyzing stress distributions around dental implants. However, FEA of living tissue involves many conditions, and the structures and behaviors are complex; thus, it is difficult to ensure the validity of the results. To verify reproducibility and validity, we embedded implants in experimental models and constructed FEA ...

despite the recent developments in peri-implant surgical regenerative procedures, re-establishing the hard and soft tissue contour is still a challenge in cases with severe ridge deficiency. it becomes more difficult when incorrectly placed implants cause screw connections to come out onto the labial surfaces of the teeth. a two-part maxillary implant supported fixed restoration was constructed...

This systematic review looks at thematic trends in clinical research publications on dental implants. For this purpose, MEDLINE electronic searches as well as additional hand searches of six main journals in the field were conducted. A total of 2875 clinical studies published between 2001 and 2012 met the inclusion criteria and were subjected to statistical analysis. Hot topics in dental implan...
