Complete excision of a neoplastic lesion on the pinna of the ear may affect the cartilaginous skeleton of this structure (Fig. 1). In contrast to the situation with other facial structures, surgery to the ear has few functional repercussions. However, cosmetic changes due to scar retraction during the healing process are common. Substitution of the cartilage is possible using alloplastic materi...

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...

The creation of new non-toxic materials that combines high osteointegration and strength characteristics is an urgent contemporary challenge. use complex oxides, such as lanthanum zirconate (La2Zr2O7), non-reservable alloplastic implant a novel promising way fulfilling this In work, the ceramic based on undoped alkali-earth (Ca, Sr) doped La2Zr2O7 were obtained. main physical chemical determine...

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...

A robust method for inducing bone-formation without an autograft has not been established. Currently, both platelet-rich plasma (PRP) and bone morphogenetic protein (BMP) have been widely investigated for their clinical use in such cases. However, their synergistic effect is still controversial and previously shown diversity of this effect depends on various factors such as the bone substitutes...

BACKGROUND Tooth replantation after traumatic avulsion or transplantation is a challenge in oral surgery. A special method named auto-alloplastic replantation, in which a titanium post is used after extraoral endodontic treatment, combines several advantages. The treatment is performed in one step with no further endodontic intervention, no wide root canal instrumentation, no recontamination, a...

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 ...

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...

BACKGROUND Ankylosis is a very common condition developed mainly after damage to mandibular condyles or temporomandibular joint (TMJ) at a growing age. Different autogenous and alloplastic interpositional materials have been attempted after the resection of the ankylotic bone to achieve desirable results. This condition is relatively common in Pakistan. We treated TMJ ankylosis with alloplastic...

BACKGROUND To date, no studies have been published in which histomorphometric data from a large group of patients comparing various biomaterials for sinus floor augmentation procedures were evaluated. MATERIALS AND METHODS A meta-analysis of the English literature from January 1993 till April 2009 was carried out. Out of 147 titles, according to our criteria, 64 articles were selected for ana...
