Objectives: Highlight the outcome of alveolar grafting with synthetic bone substitute (Osteon III) only in various defect volumes. Material and Method: Prospective study accomplished on 55 patients (6-13 years aged) unilateral cleft. Osteon III, consisting hydroxyapatite (HA) tricalcium phosphate (TCP) used to reconstruct defect. Alveolus diameter calculated before surgery (V1), after 3 months ...

Extensive defects of the scalp and forehead associated with calvarial bone resections demand complex reconstructions. Free flaps offer vascularized tissue of excellent quality and quantity. We report six patients with extensive scalp and forehead defects associated with calvarial bone resections reconstructed with free flaps. Five patients also required a cranioplasty. The flaps used were two a...

Bio-Oss (BO), composed of anorganic bovine bone, is widely used in several bone regeneration procedures in oral surgery. PerioGlas (PG) is an alloplastic material that has been used for grafting of periodontal osseous defects since the 1990s. However, how these biomaterials alter osteoblast activity to promote bone formation is poorly understood. We attempted to address this question by using m...

INTRODUCTION Ridge preservation can be performed with autologous bone, alloplastic bone substitute material or a combination of both. Dentin is similar to bone in its chemical composition. In its use as bone substitute material, it undergoes a remodelling process and transforms to bone. The presented case report introduces a technique in which the extraction socket is augmented with autologous,...

INTRODUCTION Ankylosis may be defined as the fusion of the articular surfaces with bony or fibrous tissue. The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence. PURPOSE To report 15 cases treated by either gap arthroplasty, or the articular reconstruction technique using costochondral grafts, coronoid process grafts or al...

INTRODUCTION Temporomandibular disorders encompass a set of clinical conditions that affect the temporomandibular joint, the masticatory muscles and the associated tissues. Many therapeutic alternatives can be considered, being divided into non-invasive, minimally invasive and invasive interventions. This work aims to report a case of inflammatory joint pain and dysfunction treated with bilater...

The aim of this study was to assess the nostril symmetry following primary cleft rhinoplasty done with either a dorsal onlay or columellar strut graft in patients with non-syndromic complete unilateral cleft lip and palate. In this retrospective study 30 consecutive patients treated with autogenous or alloplastic dorsal onlay grafts and 30 consecutive patients treated with autogenous or allopla...

Hemangioma of the skull is a benign solitary tumor, often found in the frontal or parietal area. A hemangioma lesion typically involves the outer table rather than the inner, but its complete removal at the diploe level is difficult. Full-thickness resection at the calvaria is often needed to ensure a free margin, but it will leave a bony defect that requires reconstruction. Although curettage ...

Besides eradication of chronic middle ear disease, the reconstruction of the sound conduction apparatus is a major goal of modern ear microsurgery. The material of choice in cases of partial ossicular replacement prosthesis is the autogenous ossicle. In the event of more extensive destruction of the ossicular chain diverse alloplastic materials, e. g. metals, ceramics, plastics or composits are...

Aims Bone defects caused by bone loss due to trauma or tumours are common, with grafting of transplanted tissue currently as the gold standard for bone replacement. However, there are many issues inherent with autograft, including donor site morbidity, supply of tissue and infection [1]. In order to overcome these drawbacks, a diverse array of synthetic biomaterials is under development [2]. Ca...
