The aim of this study was to compare and evaluate strain distribution on dental implant, abutment, screw and crown virtual models in the posterior region. The analysis was performed by means of a 3D virtual model developed by the PRO-ENGINEER System (PRO-ENGINEER, PTC, Needham, MA, USA ) with an external butt joint (3i Implant Innovations, Palm Beach, Florida), square headed Gold Tite abutment ...

PURPOSE This systematic review aimed to evaluate the effect of implant length on peri-implant marginal bone loss (MBL) and its associated influencing factors. MATERIAL AND METHODS An electronic search of the PubMed and MEDLINE databases for relevant studies published in English from November 2006 to July 2012 was performed by one examiner (AM). Selected studies were randomized clinical trials...

XIMIT is a newly developed method for precisely measuring the 2D migration of a hip socket implant using standard radiographs. 2D migration is the change of the 2D distance between implant and bone observable in the x-ray image. It is measured in order to judge the fixation of the implant in the bone. The proposed method is based on a carefully designed measurement of the 2D distance minimizing...

INTRODUCTION Children with severe to profound sensorineural deafness can acquire vocabulary and syntactic structures to communicate by oral language, after cochlear implant. AIM Identify the linguistic skills of children with cochlear implant. MATERIAL AND METHODS Eighteen children of both gender, between 9 and 10 years, with congenital bilateral deafness, using cochlear implant, were studi...

statement of problem: placement of mini-dental implants when single-tooth restorations are needed and the space is not sufficient to insert a standard diameter implant is indicated. there are many different mini-implant brands with various materials and surface characteristics; however, there are just few studies comparing them with each other. objectives: in this study, finite element analysis...

OBJECTIVE To validate a newly designed cochlear implant electrode (TRACE) in the standard monopolar mode and compare it to a patient group implanted with a standard Nucleus Contour cochlear implant electrode. The electrode contacts of the TRACE electrode have the same active surface area for stimulation, but the position in the scala tympani is different from that of the Nucleus Contour electro...

PURPOSE The aim of the present study was to evaluate the in vivo accuracy of flapless, computer-aided implant placement by comparing the three-dimensional (3D) position of planned and placed implants through an analysis of linear and angular deviations. METHODS Implant position was virtually planned using 3D planning software based on the functional and aesthetic requirements of the final res...

The aim of this study was to qualitatively evaluate the marginal vertical fit along two different implant-abutment interfaces: (1) a standard abutment on an implant and (2) a computer-aided-design/computer-aided-machine (CAD/CAM) customized screw-retained crown on an implant. Four groups were compared: three customized screw-retained crowns with three different "tolerance" values (CAD-CAM 0, CA...

context a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. the percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. evidence acquisition a number of reports have emphasized the importance of the quality of bone on the survival of dental implants. t...
