PURPOSE We review published research on temporomandibular joint (TMJ) total replacement that compares costochondral graft and customized total joint reconstruction (especially TMJ concepts), focusing on effectiveness. METHODS We searched PubMed databases, including prospective, retrospective, case-control or longitudinal studies and significant statistical analysis. In data analysis, we divid...

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...

The use of alloplastic materials in ossicular reconstruction has a long history. However, many new materials have been described and become commercially available without any evidence that they are superior to the existing ones. The aim of the present literature review is to understand why changes in materials used for ossicular reconstruction have occurred. The literature review was conducted ...

Extensive maxillofacial defects resulting from trauma or oncologic resection present reconstructive challenges. Various autografts and alloplastic materials in conjunction with standard soft-tissue techniques have been used in the reconstruction of these types of defects. Polyetheretherketone (PEEK) is a semicrystalline polyaromatic linear polymer exhibiting an excellent combination of strength...

Alloplastic materials used for orbital fracture reconstruction can induce complications, such as infection, migration, extrusion, intraorbital hemorrhage, and residual diplopia. Silicone is one of the alloplastic materials that has been widely used for decades. The author reports a rare case of spontaneous extrusion of a silicone implant that was used for orbital fracture reconstruction 30 year...

Frontobasal injuries and some other diseases of frontal sinuses sometimes require radical surgery with the obliteration of the sinus. A cosmetic correction of the forehead and supraorbital arches has to be performed after such a procedure. Nowadays, there is a wide choice of alloplastic materials on the market. We tried polymethyl methacrylate implants in correction of the exterior appearance o...

introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...

The objective of this study was to determine the relative efficacy of currently available alloplastic bone repair materials in the healing of rat calvarial defects histologically, histomorphometrically and biochemically. A representative material was selected from six major classes of bone repair materials and placed in 4 mm diameter calvarial defects of 6-week-old male Sprague-Dawley rats (fiv...

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...

BACKGROUND Reconstruction in the head and neck can be difficult owing to the size of the defect or characteristics of the tissue that needs to be replaced. Facial wounds or reconstruction sites can be subject to contamination, thereby risking infection of any implanted material even under ideal circumstances. Particular areas of concern are sites where minimizing the bacterial contamination pri...
