AIM To analyze how various implants placement variables affect sacroiliac (SI) joint range of motion. METHODS An experimentally validated finite element model of the lumbar spine and pelvis was used to simulate a fusion of the SI joint using various placement configurations of triangular implants (iFuse Implant System®). Placement configurations were varied by changing implant orientation, su...

INTRODUCTION Use of compatible abutments may increase micromovements between the abutments, and the inner part of the implant may increase the stress on marginal bone level. Also micromovement will change the volume of the inner space of the implant-abutment complex. The resulting pumping effect can transport even initially immobile microorganisms from the exterior to the interior and vice vers...

This study aimed to evaluate dental implant outcomes and to identify risk factors associated with implant failure over 12 years via dental records of patients attending an educational institution. Dental records of 202 patients receiving 774 dental implants from 2002 to 2014 were analyzed by adopting a more reliable statistical method to evaluate risk factors with patients as the unit [generali...

BACKGROUND In the last decade, the use of wide-diameter implants (WDIs; diameter >3.75 mm) has increased. Although good clinical outcomes have been reported in recent literature, there are few reports on this topic. Thus, we planned a retrospective study on a large series of WDIs to evaluate the clinical outcome. METHODS From October of 1996 to December of 2004, 205 patients were operated on,...

This is the first report of a group of 50 partially edentulous patients who received a total of 151 Endopore dental implants in the maxilla. A mean implant length of 8.7 mm was used, and 76.8% of implants were placed in the posterior maxilla. At re-entry, all implants appeared to be osseointegrated and were used to support fixed prostheses. Approximately half of the crowns (57%) in these prosth...

Performance of n-type implant free In0.25Ga0.75As MOSFETs with Ga2O3 dielectric is investigated using ensemble Monte Carlo device simulations. The implant free MOSFET concept takes an advantage of the high mobility in III-V materials to allow operation at very high speed and low power. A 100 nm gate length implant free In0.25Ga0.75As MOSFET with a layer structure derived from heterojunction tra...

The rehabilitation of patients with acquired defects of the maxilla is a challenge in terms of reestablishing oronasal separation. In most patients these goals are met by means of prosthetic rehabilitation with an obturator prosthesis. If the remaining dentition does not offer sufficient retention and support, the placement of zygoma implants can enhance the stability of the prosthesis. Due to ...

Proper implant occlusion is essential for adequate oral function and the prevention of adverse consequences, such as implant overloading. Dental implants are thought to be more prone to occlusal overloading than natural teeth because of the loss of the periodontal ligament, which provides shock absorption and periodontal mechanoreceptors, which provide tactile sensitivity and proprioceptive mot...

The purpose of this study was to evaluate the clinical application of endosseous implants for management of grafted alveolar cleft. Four patients (1 male and 3 female; mean age 26.6 years; age ranging from 21.5 to 30.4 years at first implant surgery) with unilateral cleft lip and palate were evaluated. All patients received autogenous particulate cancellous bone and marrow graft (PCBM) to close...
