The aim of this study is to evaluate a surgical protocol for vertical ridge augmentation in the maxilla and mandible using autogenous onlay bone graft associated with a titanium mesh. A group of 18 partially edentulous patients, presenting the need for vertical bone augmentation of at least 4 mm, were treated before implant placement. During the first(More)
OBJECTIVES The aim of this controlled clinical trial is to evaluate alveolar ridge augmentation using an autogenous onlay bone graft alone or associated with a titanium mesh (Ti-Mesh). MATERIAL AND METHODS A group of 23 partially edentulous patients, presenting the need for vertical bone augmentation of at least 4 mm, were treated before implant(More)
The study aimed to investigate the connective tissue seal and the spatial organization of collagen fibers around long-term loaded implants in man. Block specimens containing smooth titanium implant abutments and the surrounding supracrestal connective tissue were obtained from patients rehabilitated for at least 1 year with implant-retained overdentures or(More)
OBJECTIVES The aim of this study was to evaluate the effects of scanning parameters on the precision of the data acquired using a facial laser scanner and to assess the reliability of automatic model recording in humans. METHODS Data were acquired using a laser scanner (Cyberware 3030RGB); analysis and measurements were performed with Rapid Form 2004(More)
INTRODUCTION This report analysed the outcome of patients undergoing surgery for oral squamous cell carcinoma in order to identify the prognostic value of several factors. PATIENTS A total of 245 patients were studied who had undergone surgery for oral squamous cell carcinoma between 1989 and 2002, of whom 109 had received postoperative radiation therapy.(More)
Immunohistochemical analysis of the extrahypothalamic distribution of vasotocin-like immunoreactive elements within the central nervous system of the domestic fowl and Japanese quail, revealed several mesencephalic, pontine and bulbar target areas topographically identifiable. Extrahypothalamic immunopositive perikarya were observed in diencephalic and(More)
In 29 adult patients presenting with maxillary deficiency, a bone-anchored palatal distractor (Surgi-Tec NV, Brugge, Belgium) was applied after osteotomy of the anterolateral walls of the maxillary sinuses, midpalatal suture, and, eventually, separation of the pterygomaxillary sutures. Expansion proceeded at a rate of 0.33-0.66 mm per day and the device was(More)
Retrobulbar haematoma following blunt orbital trauma is a rare, but potentially serious, complication, since it can evolve rapidly from visual impairment to permanent loss of vision. This sight-threatening situation most commonly arises from orbital bleeding accompanying undisplaced fractures of the orbital walls, an event that increases the pressure inside(More)
In this immunocytochemical study we investigated the distribution of nervous structures in the lower lip of adult rats. The region is characterized by a rich cutaneous and mucosal sensory innervation originating from terminal branches of the trigeminal system. Lower lip innervation was investigated by detection of the general neuronal marker protein gene(More)
This longitudinal study investigated the 3-D facial soft-tissue response to transverse palatal bone-anchored osteodistraction in 18 adult patients. Laser-scanned facial surface data were obtained for all patients before (T(0)), 6 months (T(1)) and 1 year (T(2)) after transverse palatal distraction. The averaged facial morphologies at T(0), T(1) and T(2)(More)
