Introduction: Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) are the latest achievements of Prosthodontics and Restorative Dentistry. The aim of this research is to help make appropriate decision whether to use this technology in Iran. Methods: Studies were included in this review that compared Dental CAD/CAM with conventional restorativ...

The average life span of knee prosthesis used in Total Knee Replacement (TKR) is approximately 10 to 15 years. Literature indicates that the reasons for implant failures include wear, infection, instability, and stiffness. However, the majority of failures are due to wear and tear of the prosthesis. The most common biopolymer used in TKR  is Ultra High Molecular Weight Polyethylene (UHMWPE). Pr...

Objective: Due to the increasing numbers of radical prostatectomy performed for prostate cancer, a substantial and increasing number patients suffer from postoperative urinary incontinence and also erectile failure. Despite the improving surgical techniques, the reported incontinence rates are between 5% and 48%. In patients with dual problems of ED and incontinence, to see whether inflatable p...

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...

dental implants have provided exceptional rehabilitative options for edentulous and partially edentulous patients. however, as more implants come into play, the more the clinicians come across problems where specific considerations must be taken into account to meet expectations. the toronto bridge is a treatment modality proposed for restoring several teeth lost in patients with increased crow...

Although prosthesis-bone micromotion is known to influence the stability of total hip replacement, no protocol exists to investigate resurfacing hip implants. An in-vitro protocol was developed to measure prosthesis-bone micromotions of resurfaced femurs. In order to assess the effect of all loading directions, the protocol included a variety of in-vitro loading scenarios covering the range of ...

The advantage of the end-bearing ankledisarticulation amputation has been well recognized since Syme published his classic article in 1843 (2). Disadvantages and complications of this level of amputation have led some surgeons to favor amputation at a higher level. Failure of adherence of the heel pad to the distal tibia, resulting in a flabby, loose stump, prevents many amputees from ambulatin...

PURPOSE Fornix contracture is an obstacle for fitting a prosthesis in blind or enucleated patients, and may lead to disfigurement and psychological issues. This study evaluates the efficacy of amniotic membrane transplantation (AMT) for fornix reconstruction with the aim of better retention of the ocular prosthesis. METHODS This non-comparative interventional case series includes eighteen bli...

Objective: To compare survival and outcome in patients receiving a mechanical or bioprosthetic heart valve prosthesis. Design: Randomised prospective trial. Setting: Tertiary cardiac centre. Patients: Between 1975 and 1979, patients were randomised to receive either a Bjork-Shiley or a porcine prostheses. The mitral valve was replaced in 261 patients, the aortic in 211, and both valves in 61 pa...
