PURPOSE The objectives of this review were to (1) identify if prosthodontic parameters influence the esthetic outcome of implant-supported restorations and (2) make clinically relevant recommendations based upon the findings. MATERIALS AND METHODS Electronic and manual searches of dental literature were performed to collect information on esthetic outcomes based on objective criteria. The pro...

The Aramany classification system of postsurgical maxillectomy defects is a useful tool for teaching and developing obturator framework designs and enhancing communication among prosthodontists. This article describes a series of Aramany-obturator design templates and discusses the relevant considerations for each. In all situations, a quadrilateral or tripodal design is favored over a linear d...

The inability to consistently achieve a passive fit with screw-retained implant prostheses is well documented in the literature. Cement-retained implant frameworks have been advocated for implant-retained fixed partial dentures. However, cement retention has not been routinely advocated for fixed-detachable hybrid prostheses. This article describes a method for fabricating a cement-retained fix...

Screw-retained implant restorations have an advantage of predictable retention as well as retrievability, and obviate the risk of excessive sub-gingival cement commonly associated with cement retained implant restorations. Screw-retained restorations generally have screw access holes, which can compromise esthetics and weaken the porcelain around the holes. The purpose of this study is to descr...

Prosthodontic rehabilitation of completely edentulous arch with implant supported prosthesis requires a stent, to evaluate the relationship between anatomical structures and to aid in implant placement for successful treatment result. The lengthy treatment procedure where the clinician has to duplicate the existing denture for stent fabrication has created a need for an improved simple and time...

The majority of maxillary defects can be rehabilitated with conventional simple obturator prosthesis. However, inadequate retention, stability and support may be associated with the use of an obturator. Precision attachments have been used to retain obturators for some time. The use of precision attachments in a dentate maxillectomy patient can yield significant functional improvement while mai...

Construction of an obturator is necessary to restore normal function and aesthetics in patients who had a resection of a tumor in the soft and hard palates. The design of the prosthesis is affected by the remaining supporting structures of the oral cavity, presence and extent of reconstructed tissue and the severity and location of the lesion. Many adverse forces act on an obturator and these c...

STATEMENT OF PROBLEM Cast posts require sufficient length for prosthesis retention and root strength. For prefabricated metal and fiber posts, the effects of different post lengths on the strength and internal stress of the surrounding root need evaluation. PURPOSE The purpose of this study was to examine, using both experimental and finite element (FE) approaches, the influence of post mater...

Using a new, non-invasive method, we measured the patellofemoral force (PFF) in cadaver knees mounted in a rig to simulate weight-bearing. The PFF was measured from 20 degrees to 120 degrees of flexion before and after implanting three designs of knee prosthesis. Medial unicompartmental arthroplasty with a meniscal-bearing prosthesis and with retention of both cruciate ligaments caused no signi...
