ReSultS: The most common indication for reconstruction was oncologic, followed by traumatic and congenital. Patients received an average of 5.8 implants during the course of treatment. The average follow-up time was 10.6 years with a range of 6 months to 24 years. A statistically significant correlation was found between skin reaction and age (p=0.022), with younger patients more likely to deve...
PURPOSE To study the biomechanical characteristics (percent stretch, stiffness, and ultimate load) of 2 tendon-prosthesis techniques used to connect the proximal tendon stump to silicone active tendon implants used in reconstruction of flexor tendons. METHODS We evaluated percent stretch following cyclic loading and at failure, stiffness during load to failure, and ultimate load of 16 tendon-...
A case of dysfunction of a Carpentier-Edwards porcine xenograft mitral prosthesis is presented. Valve failure was diagnosed by echocardiography and confirmed at operation. Histology showed valve tissue degeneration without evidence of prosthetic endocarditis.
Abstract Background The aim of this Systematic review is to provide more accurate knowledge about the relation between bruxism, Dental implant and implant-supported prosthesis. Main body. Material methods A systematic search in Medline (PubMed) manual implant-related journals was performed February 2021 with time range extending from 2010 2021, no language restriction order identify all papers ...
rehabilitation of facial defects is a complex task, requiring an individualized design of the technique for each patient. the disfigurement associated with the loss of an eye may result in significant physical and emotional problems. various treatment modalities are available, one of which is the use of implants. although implant-supported orbital prosthesis has a superior outcome, it may not b...
Background and Aims: To create a good adhesion between porcelain veneers and zirconia restorations has been important issues is the prosthesis. The aim of this study was to identify an effective way to prepare the zirconia surface infrastructure to increase its shear bond strength to the porcelain veneer. Materials and Methods: 75 samples of zirconia (Y-TZP) cylinders (diameter of 7 mm and a t...
malignancies of the midface result in cosmetic deformities that make maxillofacial prosthesis as an integral part of the treatment plan. facial defects can be devastating in their impact on physical structure and function of the affected individual, leading to potentional compromises in quality of life. reconstruction of nasal defects is a challenge for the prosthodontist because of esthetic an...
Late complications of spontaneous urethral erosion of malleable penile prosthesis in a young patient
INTRODUCTION Most men with erectile dysfunction are initially offered systemic therapy with a phosphodiesterase type 5 inhibitor, and then a choice of intracorporeal injection or intraurethral treatment. If these initial treatments fail or are rejected, penile prosthesis implantation is usually the third-line treatment option. The technology for penile prosthesis has been evolving, and it has b...
PURPOSE This article reports the preliminary data from a clinical study of immediately loaded, full-arch, screw-retained prosthesis with distal extensions (hybrid prosthesis) supported by Osseotite implants placed in the edentulous mandible. MATERIALS AND METHODS Fifteen patients who received 103 implants were enrolled in this study. The first 2 patients received both immediately loaded and s...
OBJECTIVES To identify whether measurement of the prosthesis length is mandatory in patients requiring otosclerosis surgeries and to assess their postoperative audiometric outcomes. In addition, evaluation of prosthesis length used in revision compared to primary stapedectomy was carried out. STUDY DESIGN Case series with chart review. METHODS Chart review of 393 patients undergoing primary...
