Abstract:

Abstract OBJECTIVES Our goal was to examine post hoc patient satisfaction and the decision-making process of choosing a prosthesis for aortic valve replacement (AVR). METHODS We surveyed 113 patients who were operated on for AVR at 60–70 years of age, including 74 patients with a mechanical valve (MECH) and 39 with a bioprosthesis (BIO). The study focused on quality of life and the decision pathway in relation to prosthesis choice and valve-related complications. Decisional conflict was defined as the post hoc uncertainty perceived by patients regarding their choice of prosthesis. RESULTS The

Microelectrodes for pain management, neural prosthesis or assistances have a huge medical demand, such as the application of pain management chip or retinal prosthesis addressed on age-related macular degeneration (AMD) and the retinitis pigmentosa (RP). Due to lifelong implanted in human body and direct adhesion of neural tissues, the electrodes and associated insulation materials should possess an ideal bio-compatibility, including non-cytotoxicity and no safety concern elicited by immune responses.

Abstract:

The control scheme in a myoelectric prosthesis includes a pattern recognition section whose task is to decode an input signal, produce a respective actuation signal and drive the motors in the prosthesis limb towards the completion of the user’s intended gesture motion. The pattern recognition architecture works with a classifier which is typically trained and calibrated offline with a supervised learning framework. This method involves the training of classifiers which form part of the pattern recognition scheme, but also induces additional and often undesired lead time in the prosthesis desi

Abstract:

One of the most important problems of total hip replacement is aseptic loosening of the femoral component, which is related to the changes of the stress distribution pattern after implantation of the prosthesis. Stress shielding of the femur is recognized as a primary factor in aseptic loosening of hip replacements. Utilizing different materials is one of the ordinary solutions for that problem, but using functionally graded materials (FGMs) could be better than the conventional solutions.

The knee osteoarthritis requires the latter joint replacement by a total knee prosthe-sis (TKP). Generally, this prosthesis consists of three parts; a femoral component in CoCrMo cobalt alloy, a tibial insert in polyethylene, and a tibial tray in titanium alloy Ti6AL4V. This type of prosthesis is not 100 % comfortable, after years of implantation, the tibial insert (polyethylene) degrades and gives more wear debris, which affects the bio-functionality of this prosthesis and the patient life.

Abstract:

Artificial intelligence (AI) is the data-driven disruptive technology of modern times. AI is reforming every field from space science to dentistry. Bio-medical provides various advantages over conventional diagnosis, treatment planning, patient documentation and management. Every field is implementing AI for the ease of both doctors and patients. In this present work, the review was done for the implementation of AI in prosthodontics. Prosthetic dentistry or prosthodontics is one of the branches of dentistry, mainly deals with replacement and rehabilitation of missing teeth with the help of fi

Abstract:

The success rate of the given fixed partial denture and the longevity of the fixed partial denture is depend on the tooth preparation and the usage of the luting cement under the fixed partial denture prosthesis. Luting cement plays an important role in maintaining or securing the fixed partial denture prosthesis in the cemented position. Luting cement should be bio compatible, it should be non-irritating to the underlying tooth structure and non-irritating to the pulp, it should maintain the adequate marginal seal. In recent days so many newer luting cements has been introduced in to the dent

Abstract:

The article deals with the design processes of modern prostheses of the upper limbs, including the prosthetic sleeve. It has been established that the applied design methods and manufacturing technologies for prosthetic sleeves do not take into account the elastic-rigidity characteristics of human hand tissues interacting with the prosthesis. The review made it possible to determine the existing problems in the field of creating prosthetic sleeves. The authors considered the issues of using data from the results of the experiment to reconstruct the forces that arise between the patient's stump

Abstract:

To the presence healthy teeth is an integral part of human health. Their partial or complete loss can have complex consequences for our functioning and quality of life. There are a number of factors that lead to tooth loss. In particular, genetic factors, periodontal diseases, caries complications, poor diet and bad habits. In some cases, tooth loss can be hereditary, caused by an increased tendency to develop caries or periodontal diseases. The presence of various abnormalities in the development of teeth can also be the reason for their loss in the future. Furthermore, the most common method

Abstract:

Objective In this paper, we present an endoscopic expandable sizer conceived to allow thoracoscopic aortic valve replacement with a sutureless prosthesis using a dynamic sizing of the aortic annulus. Methods Ten aortic torsos were prepared using a five-trocar thoracoscopic setting. Once the aortotomy was performed and the aortic valve leaflets removed, the technical feasibility of the endoscopic sizing (introduction into the trocar, expansion into the aortic annulus, determination of the valve size, and retraction) with the device was assessed. In case of successful thoracoscopic sizing, endos

Introduction: Candidiasis or Candidosis are designated names designated as infectious names for fungi of the genus Candida spp., which establish a commensal relationship with the immune system when the system is depressed or by some pathogenic infections. As proposals of oral candidiasis can be hyperplastic in primary and secondary cited by the following types: pseudoplastic, erythematous, pseudomembrane, erythematous; there is a category called “lesions also associated with Candida spp.”, which includes denture stomatitis (PE).

Abstract:

The use of vascular bypass grafts in patients is not new. The high prevalence of atherosclerosis has seen them being used in the treatment of some of the 800 000 cases of myocardial infarction in the UK. So, is there a need for tissue-engineered blood vessels if there is a functional prosthetic alternative? While this may hold true for vessels with high-blood-flow rates1, the patency rates of poly(ethylene terephthalate) (Dacron®) and expanded polytetrafluoroethylene (ePTFE) grafts are less satisfactory at lower flow rates. Given the limitations with synthetic materials alone, a biological or
