Calibration loss of ovens used in sintering metal ceramic prostheses leads to stress and cracks in the material of the prostheses fabricated, and ultimately to failure of the dental treatment. Periodic calibration may not be sufficient to prevent such consequences. Evaluation methods based on firing supplemental control samples are subjective, time-consuming, and rely entirely on the technician...

AIM The use of synthetic mesh in transplant patients is still under debate. In this paper the authors report their preliminary experience on biological prosthesis for surgical treatment of incisional hernias in transplant patients. MATERIAL OF STUDY Between 2009-2010, 10 patients with incisional hernia underwent surgery using a biological prosthesis (porcine dermis collagen). All patients wer...

STATEMENT OF PROBLEM Measures of satisfaction after extraoral maxillofacial prosthetic rehabilitation have been sparsely reported. PURPOSE This article reviews the care-related opinions of patients who were provided extraoral prostheses at the M. D. Anderson Cancer Center over the course of 10 years. MATERIAL AND METHODS A questionnaire was delivered to 263 extraoral prosthetic patients to ...

A report of the outcome of fitting ICEROSS prostheses to trans-tibial amputees from a subregional amputee rehabilitation centre is presented. This work has mainly concentrated on obtaining patients' own views to judge advantages and disadvantages of ICEROSS compared to their previous patellar-tendon-bearing (PTB) prostheses. Sixty-nine patients were entered for this study, but the results of th...

Being edentulous is a handicap, and the main objective of implant placement is to provide support of fixed prostheses or to stabilize complete dentures in the edentulous jaw. Clinical experience and clinical studies have demonstrated the broad application of non-submerged ITI implants in prosthetic therapy in standard sites and in situations of advanced atrophy or substantial loss of tissue. Th...

INTRODUCTION: THE NEUROBIOLOGY OF THE WILL The will is a complex set of cognitive (including affective and motivational) and motor capacities that enable us to initiate and complete action plans. Neurological and psychiatric disorders impair these capacities because of dysfunction in neural circuits mediating them. Parkinson’s disease (PD), major depressive disorder (MDD), obsessive-compulsive ...

This study investigated detection thresholds of vibrometric stimuli in patients with transfemoral amputation supplied with osseointegrated (OI) and socket-suspended prostheses. It included 17 patients tested preoperatively with socket-suspended prostheses and after 2 yr with OI prostheses and a control group (n = 17) using socket-suspended prostheses, evaluated once. Assessments on the prosthet...

OBJECTIVE To evaluate the reliability and safety of penile implants in the treatment of organic impotence at the Saudi Aramco - Dhahran Health Center. METHODS A series of 108 cases of organic impotence that underwent 125 penile implantation procedures between 1988 and 1997 was reviewed. The follow-up period ranged between 6 months and 10 years. The mean age was 57.9 years (range 26-76). The p...

Silicone gel-filled breast implants nowadays are commonly used in breast surgery. Despite the improvements carried out during the years in the device design and manufacturing technologies, the long-term reliability of such prostheses is still doubted and the phenomena involved in the prostheses failure not yet clearly defined. This study investigates rupture causes by analysing the mechanical p...

Prosthetic valve replacement remains the most viable alternative for the treatment of severely diseased heart valves. The cumulative experience of mechanical protheses and bioprostheses was evaluated for a 10-year performance comparison: Carpentier-Edwards standard porcine bioprosthesis (CE-S), 1,214 operations; Carpentier-Edwards supraannular porcine bioprosthesis (CE-SAV), 2,489; and mechanic...
