INTRODUCTION Dental implants are increasingly used to restore missing dentition. These titanium implants are surgically installed in the edentulous alveolar ridge and allowed to osteointegrate with the bone during the healing phase. After osseo-integration, the implant is loaded with a prosthesis to replace the missing tooth. Conventional implant treatment planning uses study models, wax-ups an...
This study investigates the relative effect of soft tissue properties on the overall response of a human spinal motion segment using an osseo-ligamentous FE model of the Visible Man L3-L4 intervertebral joint. Model geometry was obtained from the Visible Man CT dataset using custom built image processing software. Non-linear soft tissue properties were obtained from the literature. Displacement...
For further improvement of osseo-integration of bone crystal with a dental implant, a design optimization study is carried out for various holes inside its body to deliver bioactive materials and the effect of bioactive material injection on the bone crystal growing. When bioactive material is absorbed, the bone crystal can grow into holes, which would increase the strength of implant bonding a...
Titanium (Ti) is a widely used material for surgical implants; total joint replacements (TJRs), screws and plates for fixing bones and dental implants are forged from Ti. Whilst Ti integrates well into host tissue approximately 10% of TJRs will fail in the lifetime of the patient through a process known as aseptic loosening. These failures necessitate revision arthroplasties which are more comp...
Veno-occlusive disease (VOD) is a complication arising from the toxicity of conditioning regimens that have a significant impact on the survival of patients who undergo stem cell transplantation. There are several known risk factors for developing VOD and their assessment before the start of conditioning regimens could improve the quality of care. Equally important are early identification of s...
Advances in head and neck reconstruction has made signiÞ cant improvement in the quality of life and resectability of head and neck cancer. ReÞ nements in microsurgical free tissue transfer leave made restoration of form and complex functions of head and region a reality. Standardized reconstructive algorithms for common head and neck defects have been developed with predictable results. Some o...
Imaging of the blunt traumatic injuries to the craniocervical junction can be challenging but central to improving morbidity and mortality related to such injury. The radiologist has a significant part to play in the appropriate management of patients who have suffered injury to this vital junction between the cranium and the spine. Knowledge of the embryology and normal anatomy as well as norm...
This review summarizes published literature from a range of reputable sources regarding hip prostheses (stems) utilized currently in cementless Total Hip Arthroplasty. The critical review of published clinical studies shows Zweymuller style (Alloclassic and SL-Plus) stems in all critical characteristics. Since the introduction of cementless total hip arthroplasty in the 1970s, a range of design...
PURPOSE Authors' clinical and surgical experience in correction of the radial polydactyly in its various degrees of severity is presented. MATERIAL AND METHODS Nineteen patients were operated due to thumb duplication in a 10-year period from 1996 to 2006. The cases were classified according to Wassel 7-type classification. The surgical techniques adopted were the Bilhaut-Cloquet and the metho...
