BACKGROUND PerioGlas® (PG) is an alloplastic material used for grafting periodontal osseous defects since 1995. In animal models, it has been proven that PG achieves histologically good repair of sur-gically created defects. In clinical trials, PG was effective as an adjunct to conventional surgery in the treatment of intrabony defects. Because the molecular events due to PG that are able to al...

Craniofacial defects represent alterations in the anatomy and morphology of the cranial vault and the facial bones that potentially affect an individual's psychological and social well-being. Although a variety of techniques and restorative procedures have been described for the reconstruction of the affected area, polymethyl methacrylate (PMMA), a biocompatible and nondegradable acrylic resin-...

Abstract Biomaterials are routinely used in dentistry for tissue engineering. The purpose of the present work is to compare performance a new alloplastic biomaterial (Blue-Bone®), xenogeneic (Bio-Oss®), and mixture both biomaterials with 50% autogenous bone. 32 Wistar rats underwent surgical procedure which circular disc bone was removed from calvaria trephine drill 10 mm diameter create critic...

INTRODUCTION Auricular reconstruction is a great challenge in facial plastic surgery. With the advances in surgical techniques and biotechnology, different options are available for consideration. The aim of this paper is to review the knowledge about the various techniques for total auricular reconstruction based on the literature and our experience. METHODS Approximately 179 articles publis...

BACKGROUND Ceramic hydroxyapatites and non-ceramic hydroxyapatites have been used extensively as alloplastic materials for bone reconstruction. However, different forms of hydroxyapatite induce different types of tissue response. METHODS Human gingival fibroblasts (FMM1 cells) were used to analyze ceramic and non-ceramic hydroxyapatite biocompatibility. The cells were grown on surfaces covere...

d d s a ecause of the complex structure of the orbital walls, he fracture patterns vary considerably in their locaion as well as in their degree of severity.1 Multiple ortions of the orbit can be fractured and several nternal orbital walls therefore injured simultaeously. The ideal reconstruction material for orbital floor or all reconstruction should be easy to mold, easy to nchor, biocompatib...

Management of posttraumatic enophthalmos can present as a challenge to the reconstructive surgeon, particularly in cases of late presentation. This article reviews the pertinent anatomy of the orbit, diagnostic modalities, indications for surgery, and surgical approaches as they relate to the treatment of posttraumatic enophthalmos. Internal orbital reconstruction has evolved to an elegant proc...

The frontotempotal-orbitozygomatic craniotomy (FTOZ) is a standard approach for large sphenoid wing meningiomas (SWMs). Nevertheless, resection of these tumors is not without ophthalmologic risks. This series presents two patients with acute postoperative restrictive strabismus following tumor resection and orbital wall reconstruction. Forced duction testing and postoperative imaging revealed i...
