We have designed a new polycentric knee adopting a hydraulic unit and an intelligent mechanism. The biomechanical parameters of this prototype, such as the stance duration, peak knee flexion angle in stance and swing, peak hip flexion angle, and peak hip extension moments were analyzed at three different cadences (88, 96, 104 steps/min) in three amputees, and then compared to those of polycentr...
Abstract The implant-supported removable partial dentures should be an alternative to conventional removable partial dentures and implant-supported fixed partial prostheses when the implant’s insertion is confined by bone height and thickness. Placing a single implant in the posterior region would modify the Kennedy Class II configuration to a Kennedy Class III and increase the stability a...
implant-supported craniofacial prostheses are made to restore defective areas in the face and cranium. this clinical report describes a technique for fabrication of an orbital prosthesis with three adjacent implants in the left lateral orbital rim of a 60-year-old woman. selection of appropriate attachment system (individual magnetic abutments versus bar-clip attachment) for implant-supported o...
The implant-retained fixed prosthesis has been advocated as an effective restoration offering significant benefits over conventional prosthetics. The success of treatment depends on careful pre-surgical planning and prosthesis design. This paper outlines some common complications encountered during the planning, fabrication and maintenance of both large and small fixed prostheses and suggests h...
The fabrication of an implant-supported fixed complete denture prosthesis involves multiple clinical and laboratory steps. One of the main steps is to provide the patient with an interim fixed prosthesis to evaluate the patient's esthetic and functional needs as well as to enhance the patient's psychology before proceeding to the definitive prosthesis. Different techniques for fabricating inter...
OBJECTIVES Two steps in stapedotomy are particularly challenging: (1) micropick fenestration of the stapes footplate (SF) and (2) crimping of the stapes prosthesis (SP) to the incus. We conducted trials to determine if experience correlates with differences in performance for these tasks. METHODS In a surgical model of stapedotomy, performance was measured for 3 experienced and 3 novice surge...
