Abstract This clinical report presents a case of abutment fracture, due to occlusal overload, occurred with an implant-supported restoration on right mandibular first molar of a female patient. After 6 months of prosthetic reconstruction implants, the patient returned to the clinic due to the loss of implant crown. The fractured fragment of the abutment with the screw protec...

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...

STATEMENT OF PROBLEM The choice of single-molar implant design is difficult because of a lack of controlled, quantitative biomechanical analyses. PURPOSE This study determined the effect of 3 single-molar implant designs on implant strains under a variety of homologous loading conditions. MATERIAL AND METHODS On each implant abutment, 4 strain gauges were placed axially at 90 degrees to eac...

The application of implants for dental and orthopedic surgery has increased rapidly within the past few decades. In craniomaxillofacial surgery, different implant systems have been applied, for example, for dental and bone replacement or osteosynthesis plates and screws. These implants may be made of pure titanium or a titanium alloy, usually titanium-aluminumvanadium (Ti-6Al-4V). The surface c...

objective: the aim of our study is to determine the impact of cochlear implantation on anxiety anddepression in mothers of children with cochlear implant. materials and methods: in a cohort design, 35 mothers of deaf children with cochlear implantion admitted to the clinic of baqiyatallah hospital during january 2008 – january 2010 were selected through systematic sampling. information of demog...

A key feature of the ASTRA TECH Implant System BioManagement Complex is the design of the implant-abutment connection, i.e. the Conical Seal Design. This design feature has been part of the implant system since 1985, thus all clinical documentation available includes results on this key feature. This review includes technical literature focusing on evaluating the Conical Seal Design, using appr...

Glenoid implant design and alignment are critical to the success of shoulder arthroplasty. Computer-aided design models of 3 glenoid implant designs (keel, standard pegs, and modified pegs) were virtually implanted into 3-dimensional computed tomography-reconstructed models of 40 normal scapulae. The incidence of perforation on 3-dimensional computed tomography preoperative templating varied fr...

In medical and surgery applications, the implant design is the key. Any mismatch in the implant design results in the implant failure as well as psychological stress and pain to the patient. Measuring and inspecting the geometrical implant design with the reference model is very important, to ensure the proper fitting and safety of the patient. The purpose of this study is to perform the evalua...

Although dental implants have become a predictable aspect of tooth replacement in prosthodontic treatment [1, 2, 3, 4, 5, 6], failures of up to 10% are still encountered. Furthermore these failures have been more associated with “soft” bone quality [7], 1985) such as encountered in the maxillary posterior area [8, 9, 10, 11, 12]. In a review article by Esposito et al [13], bone quality and volu...
