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)
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)
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)
The present study elucidates the morphology of encapsulated receptors in human skin by means of immunohistochemistry for the recently characterized neurospecific marker protein gene product 9.5, in comparison with neuronal specific enolase and S-100 protein. Only two types of corpuscles are identified, Meissner's corpuscles and simple coiled corpuscles.(More)
Fifteen patients who underwent a split thickness skin graft operation for full thickness burns and six patients with postburn scars were biopsied after a standard aesthesiological examination completed with Weber and Dellon tests. A semiquantitative evaluation was performed on immunohistochemically stained sections to determine the presence or absence of(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)
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)
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)
The platysma myocutaneous flap (PMF) was first applied to intraoral reconstructions in 1978. PMF is not only an alternative to microvascular flaps but it also represents an excellent reconstructive choice especially in cases where free tissue transfer cannot be carried out. Failure and complications rate have been described as varying from 18 to 45% and(More)
Neuronal morphology and dendritic architecture of the tuberal and mammillary regions in the hypothalamus of the quail (Coturnix coturnix japonica) were investigated by means of classical neuroanatomical methods (Bodian silver impregnation, Luxol-fast blue, cresyl violet, toluidine blue, rapid Golgi method). The tuberal region is characterized by(More)
