Benign or malignant tumor is one of the frequent causes resection mandible. The extent and location decides mode treatment neoplastic lesion. Surgical removal oral neoplasm leads to an extensive mandible along with associated structures. Objective: This case report describes use palatal ramp prosthesis guide during movements restore a stable occlusal relationship additional acrylic buccal pad a...

A mitral prosthesis, when implanted, can distort the aortic annulus, forcing to downsize the aortic prosthesis. Changing the sequence of tying the sutures (the aortic prosthesis first, then the mitral prosthesis) allows to insert an aortic true-sized prosthesis. In case of associated tricuspid valve surgery, the aortic prosthesis protrudes over the anteroseptal commissure area. The sutures on t...

We report the case of a recurrent phosphaturic mesenchymal tumor (PHT) of the right acetabulum in a 47-year-old man with a long history of hip pain. After primary excision of the PHT, successful remission was expected due to normal phosphate levels. Over a long period, a recurrence led to destruction of the acetabulum and loosening of the back plate of the hip prosthesis. One-year follow-up aft...

STATEMENT OF PROBLEM Speech bulbs and palatal lift prostheses are used to improve oral-nasal balance in speakers with hypernasality resulting from velopharyngeal dysfunction. Fabricating such speech prostheses is often a protracted process, and the nasopharyngeal impression can be uncomfortable for the client. PURPOSE The purpose of this study was to develop and test a modular palatal lift pr...

objectives: this paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. the objective was to control the ankle hysteresis at slow and normal walking speeds. methods: inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for ad...

A 16-year-old boy was submitted to a cardiac examination after an episode of faintness. A transthoracic echocardiogram was performed, which revealed a very mobile multicystic tumor attached to the mitral valve. A small solid mass adherent to the cysts was better defined by transesophageal echocardiography. The patient was submitted to cardiac surgery consisting of tumor resection and a mitral p...

INTRODUCTION Surgical resection of a malignant bone tumor (BT) or soft tissue tumor (STT), with or without prosthetic replacement, carries a high risk of developing postoperative infections. There is limited knowledge on the bacteriological spectrum of these postsurgical infections that necessitate empirical antibiotic therapy. The aim of this study was to analyze the incidence and microbiologi...

rapid prototyping (rp) is a technique of manufacturing parts by the additive layer manufacturing technology; where, a three-dimensional (3d) model created in a computer aided design (cad) system is sectioned into 2d profiles, which are further constructed by rp layer by layer. its use is not limited to industrial or engineering fields and has extended to the medical field for the manufacturing ...

X-ray and cineradiography measurements were used to compare the suspension effect and stability of a TSB trans-tibial prosthesis with an Icelandic Roll-On Silicone Socket (ICEROSS) system to that of a PTB trans-tibial prosthesis. The suspension effect was measured by the distance between the tibia and the socket in both suspension position and weight-bearing position in both type of prostheses....
