The sinusoidal thread design of the LaminOss (Impladent Ltd, Holliswood, NY) osteocompressive immediate-load implant is structured with minimal shear interface to function in horizontal planes and stimulate bone growth by the action of streaming potentials at the implant thread surface area. This implant design, when used with a unique surgical instrumentation technique, allows maximum bone to ...

The absence of periodontium causes masticatory load in excess of the self-repairing potential of peri-implant bone; peri-implant bone loss caused by occlusal overload is not uncommon in patients and greatly diminishes chances of long-term success. Regenerative treatments may be useful in inducing peri-implant bone regeneration, but are only stopgap solutions to the aftermaths caused by the impe...

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...

Latin hypercube designs (LHDs), widely used for computer experiments, are a very large class of designs with desirable properties. Recently, a number of methods have been proposed to construct orthogonal LHDs. In this paper, we introduce an approach to constructing 2-order orthogonal designs. The methods are simple and easy to implement. Using orthogonal designs, we propose some methods for con...

Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges, the t...

Traditional knee replacement designs utilize multiple discrete radii to define the sagittal plane curvature of the femoral component (Fig. 1). This geometry was derived to replicate the function of the natural knee joint. The broader distal radius articulating against a relatively congruent tibial insert provides increased constraint and reduced contact stress in the range of flexion used for h...

Introdouction: Although highly desirable outcomes and longterm survival of dental implant treatments are well documented, implant failures still occur due to various reasons. Several risk factors may impair implant survival including implant dimensions (length, diameter, and implant design), procedures, local bone density at the implant site, and patient-related risk factors such as age, smokin...

10 Statistical shape analysis techniques have shown to be efficient tools to build pop11 ulation specific models of anatomical variability. Their use is commonplace as prior 12 models for segmentation, in which case the instance from the shape model that 13 best fits the image data is sought. In certain cases, however, it is not just the most 14 likely instance that must be searched, but rather...

Despite the predictable longevity of implant prosthesis, there is an ongoing interest to continue to improve implant prosthodontic treatment and outcomes. One of the developments is the application of computer-aided design and computer-aided manufacturing (CAD/CAM) to produce implant abutments and frameworks from metal or ceramic materials. The aim of this narrative review is to critically eval...
