Alloplastic materials are frequently used in facial plastic surgeries such as rhinoplasty and nasal reconstruction. Unfortunately, the ideal alloplastic material has not been found. This experimental study evaluates the tissue response and durability of five novel polymers developed as an alloplastic material. In this experimental study involving a tertiary university hospital, six subcuticular...
PURPOSE The objective of this study was to clinically evaluate the use of OSTEON as a sinus graft material and to measure the effect of healing at 4 and 6 months after surgery. MATERIALS AND METHODS After sinus graft using OSTEON in 17 patients, bone specimens were collected from lateral sinus using 2.0-mm trephine bur at the time of 4 or 6 months after surgery. Histology of the bone specimen...
Implants have a predictable outcome and are the foremost treatment modality for prosthetic rehabilitation of edentulous patients. Due to loss of bone after extraction and pneumatization of maxillary sinus, there is insufficient bone volume for implant placement. The direct maxillary sinus lift procedure has been performed with different grafting materials (autogenous bone grafts, alloplasts, al...
Larger cranial bone defects can cause cranial disfigurement as well as potential mechanical brain trauma. Conventionally pre-fabricated acrylic cranioplasty implants require complicated procedures and result in potential dimensional and contour inaccuracies. The development of stereolithographic techniques for generating acrylic resin skull models allows the pre-fabrication of custom acrylic re...
جایگزینی دندان های از دست رفته به وسیله ایمپلنت دندانی به فراوانی انجام میشود. برای اینکه ایمپلنت به طور بهینه جایگزین شود باید در استخوان ایده ال جایگذاری شود که البته این نقایص قابل ترمیم هستند، یکی از این روشها guided bone regeneration است.
Porous polyethylene (Medpor) is an alloplastic material worldwide used for craniofacial reconstruction. To evaluate complications and risk factors associated with this synthetic graft, a retrospective study was performed. A series of 285 Medpor grafts were placed in 187 patients. Age, sex, diagnosis at admission, site, type of surgical insertion, type of fixation, and outcome (no complications,...
Patients with poor levator function require ptosis correction by a sling procedure. A variety of synthetic materials are available for this suspension, but there is a recognized complication rate. Autografts are less prone to infection and extrusion than alloplastic materials. Harvesting temporalis fascia has a number of advantages over the use of fascia lata and outcomes have been effective. A...
Large full-thickness chest wall reconstruction requires an alloplastic material to ensure chest wall stability, as well as a flap that provides good soft-tissue coverage. The choice not to use perforator flaps over any mesh or inert material is often based on the concern that the vascularization would be inadequate. However, perforator flaps have shown good results in several reconstructive fie...
