PURPOSE The long-term results of endosseous implants depend on the maintenance of bone support. The aim of this study was to evaluate radiologically bone resorption around dental implants placed in grafted sinuses after up to 4 years of function. MATERIALS AND METHODS Between 1997 and 2001, augmentation of the maxillary sinus floor with alloplastic (Biostite) or xenogenic (Bio-Oss) materials ...

BACKGROUND The literature on total alloplastic temporomandibular joint (TMJ) reconstructions is encouraging, and studies on total alloplastic TMJ replacements outcomes showed acceptable improvements in terms of both pain levels and jaw function. Nevertheless, some adverse events, such as heterotopic bone formation around the implanted prosthesis, may occur. In consideration of that, the present...

Introduction. The loss of the jaw bone, especially in area alveolar process, can significantly complicate procedure prosthetic rehabilitation patients. reason for bones are physiological and pathological processes. Materials. Bone replacements widely used reconstruction bone defects. optimal characteristics these materials biocompatibility, bioinertness, biofunctionality a special canalicular i...

Purpose. To present a novel protocol for alveolar bone regeneration in parallel to early implant placement. Methods. 497 patients in need of extraction and early implant placement with simultaneous bone augmentation were treated in a period of 10 years. In all patients the same specific method was followed and grafting was performed utilizing in situ hardening fully resorbable alloplastic graft...

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...

Maxillary reconstruction is a common procedure in maxillofacial surgery; for this purpose is used autogenous bone, alloplastic bone or another one with different results. In all of them, traditionally the use of computed tomography is used to make the surgical plan, however, 3D models are not used frequently. This report show a new application of the stereolithography to anticipate the surgical...

PURPOSE Augmentation rhinoplasty using alloplastic materials is a relatively common procedure among Asians. Silicon, expanded polytetrafluoroethylene (Gore-tex®), and porous high density polyethylene (Medpor®) are most frequently used materials. This study was conducted to analyze revisional rhinoplasty cases with alloplastic materials, and to investigate the usage of alloplastic materials and ...

Regenerative medicine provides different therapy alternatives alongside gold standard autogenous grafts for the treatment of periodontal or peri-implant osseous defects. Continuing progress in the field of alloplastic bone substitutes has yielded promising solutions to the appropriate indications with the membrane technique either alone or in combination with enamel matrix derivatives. Their cl...
