Introduction Impotence is defined as the inability to achieve and maintain an erection adequate for satisfactory intercourse. It is a common problem for approximately 50% of men between the ages of 40 and 70. Impotence not only creates mental stresses in both the patient and his partner, but also can negatively affect self-esteem. In this study, computational biomechanical modeling tools have b...

In contemporary science, the analysis of human walking is extensively used. The prediction of leg motion, as well as rehabilitation, can be usable for orthosis and prosthesis programing. Our work is focused on predicting of human walking by angle-angle diagrams, also called cyclograms. The applications of cyclograms in conjunction with artificial intelligence offers wide area of applications in...

The following paper introduces the problem of noninvasive pressure measurements in Polish artificial heart prosthesis. The pressure sensor is proposed and introduced, and preliminary tests are shown. The paper deals with the proposed sensing elements, requirement noninvasive solution and preliminary tests of polyurethane membrane transmission. The paper includes also experimental results of a f...

This study case presents a 53 years old patient with severe aesthetic dysfunctions due to an ectopic maxillary canine associated with a frontal edentulous space. Orthodontic treatment proposition was refused by the patient. After canine extraction, metalo-ceramic fixed partial prosthesis successfully restored the aesthetic damage in the conditions of a non-gingival smile. Adapted abutment teeth...

A 42-year-old male patient complaint with missing right eye was referred to the Department of Prosthodontics and Crown and Bridge. This patient was seeking artificial eye replacement. On careful clinical examination, a defect with a shrunken orbit and intact tissue bed was found in the patient. As the patient was economically very poor, modified stock ocular prosthesis was advised. To rehabilit...

Haematogenous contamination of cemented total knee replacements with an anaerobic microorganism, Propionibacterium acnes, was studied in rabbits. Seven weeks after operation the bacteria were injected intravenously and seven weeks after this bacterial challenge the experimental bacterial strain was cultured from 50 per cent of the artificial joints. Bacterial growth at the prosthesis was not co...

Artificial valve replacement is a common procedure in case of heart valve disorders treatment. The main task of this prosthesis is to generate blood flow similar to flow generated by natural, human valve. Velocity distribution depends mainly on the geometry of the valve. That is why it should be analysed and modified in case to obtain the best results. The objective of this study was to numeric...

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...
