One of the most difficult problems in the design of prostheses is the development of the best means of attaching the prosthesis to the wearer. In lower-extremity cases, transmission of forces between stump and prosthesis is of primary importance. To effect efficient transmission of forces, a stable connection between stump and prosthesis is necessary. At the same time comfort and freedom of mot...

A technique is described in which a single interim abutment and crown were fabricated in advance and placed the day of dental implant surgery. The contours of the interim crown were identical to the contours of a tentatively designed definitive prosthesis and allowed the tissue to heal and obtain contours that accommodated the contours of the definitive prosthesis. After osseointegration was es...

Rehabilitation of facial defects is a complex task, requiring an individualized design of the technique for each patient. The disfigurement associated with the loss of an eye may result in significant physical and emotional problems. Various treat-ment modalities are available, one of which is the use of implants. Although implant-supported orbital prosthesis has a su-perior outcome, it may not...

Fabricating a surveyed prosthesis beneath an existing partial removable dental prosthesis (PRDP) is a challenging and time-consuming procedure. The computer-aided design/computer-assisted manufacturing (CAD/CAM) technology was applied to fabricate a retrofitted, surveyed zirconia prosthesis to an existing PRDP. CAD/CAM technology enabled precise and easy replication of the contour of the planne...

KENDIR, GURHAN ALPER. An Efficient Transcutaneous Power Link Design to Be Used In Retinal Prosthesis. (Under the direction of Dr. Wentai LIU) Design of the radio-frequency power links to be used in prosthetic body implanted systems is important. In this study, we present a novel design procedure for the coil design considering both the efficiency of the system and the radiated magnetic field. C...

BACKGROUND Current outcome measures used in upper limb myoelectric prosthesis studies include clinical tests of function and self-report questionnaires on real-world prosthesis use. Research in other cohorts has questioned both the validity of self-report as an activity assessment tool and the relationship between clinical functionality and real-world upper limb activity. Previously,1 we report...

INTRODUCTION: The range of motion (ROM) after total knee arthroplasty (TKA) is one of the most important factors for patient satisfaction, especially in Asian countries. To enhance the knee flexion angle, “highflexion” designs have been introduced in total knee prostheses. One of such design was a new design of femoral prosthesis, which increased the posterior cut on the bone by 2 mm and thicke...

This paper presents a functional architecture, system level design, and preliminary experimental evaluation of a unilateral vestibular prosthesis. The sensing element of the prosthesis is a custom designed one-axis MEMS gyroscope. Similarly to the natural semicircular canal, the microscopic gyroscope senses angular motion of the head and generates voltages proportional to the corresponding angu...
