abstract facial defects not only impact on the function and quality of life but also affect the psychological well-being and social behavior of patients. a nasal prosthesis can re-establish the esthetics and anatomical contour in patients with mid-facial defects, often more effectively than surgical reconstruction. for successful results, many factors such as retention, texture, color match and...

The importance of an accurately fitting fixed prosthesis or a removable prosthesis is essential for the success of the restoration. Ill-fitting prosthesis may cause mechanical failures of the prosthesis, implant systems, or biologic complications of the surrounding tissue. There are several causes related to improper seating of the prosthesis. Some of which can be corrected and the others need ...

The fabrication of an implant-supported fixed complete denture prosthesis involves multiple clinical and laboratory steps. One of the main steps is to provide the patient with an interim fixed prosthesis to evaluate the patient's esthetic and functional needs as well as to enhance the patient's psychology before proceeding to the definitive prosthesis. Different techniques for fabricating inter...

BACKGROUND Most of the current available cervical disc prostheses present a flat surface instead of an arcuate surface which is most similar to the morphology of cervical endplate. Therefore, we designed a novel prosthesis (Pretic-I, Trauson) based on the physiological curvature of the cervical endplate. Biomechanical evaluation of cervical disc replacement (CDR) with this novel prosthesis was ...

purpose: to determine the efficacy of primary placement of a titanium sleeve and peg on hydroxyapatite (ha) orbital implants. methods: this retrospective non-comparative interventional case series was performed on 34 patients undergoing enucleation. a standard enucleation technique with primary ha implantation was performed, in which titanium sleeve and peg were placed primarily during the init...

In developing countries locally-made low-cost prostheses are mainly used in limb-salvage surgery to alleviate the economic burden. We retrospectively collected data on 104 patients treated by limb-salvage surgery between July 1997 and July 2005. We used a locally-designed and fabricated stainless-steel endoprosthesis in each case. Oncological and functional outcomes were evaluated at a mean fol...

OBJECTIVE A prospective, observational study was undertaken to investigate the epidemiology of oral infection among the patients with advanced malignancies, and to investigate the effects of therapy strategies and risk factors on the incidence of oral infection. METHODS The patients with advanced malignancies were enrolled into the study. The incidence of oral infection with different maligna...

background: osteosarcoma is the most common bone sarcoma, and the third most common malignancy in children and adolescents. before 1970, amputation was the sole treatment. eighty percent of patients died from metastatic diseases, most commonly in the lungs. over the past three decades, effective neoadjuvant (preoperative) and adjuvant (postoperative) chemotherapy protocols have improved the abi...
