BACKGROUND This investigation is a clinical and histological assessment of fresh-frozen bone use in the reconstruction of maxillary alveolar ridges. The study evaluates the effectiveness of this material as a bone filler prior the placement of dental implants. PATIENTS AND METHODS Sixteen patients with atrophic maxillary ridges underwent maxillary(More)
Autologous bone, for its osteoconductive, osteoinductive and osteogenetic properties, has been considered to be the gold standard for maxillary sinus augmentation procedures. Autograft procedures bring also some disadvantages: sometimes the limited amount of available intraoral bone makes necessary to obtain bone from an extraoral site, and this carries an(More)
BACKGROUND There is a lack of consensus on the appropriate management of solitary plasmacytoma (SP) of the jaw. The aim of the present investigation was to provide scientific evidence for the optimal management of this disease through a systematic literature review. METHODS The included articles are published in English from 1948 to March 2011 and(More)
BACKGROUND The harmonic scalpel (HS) has been used successfully in several head and neck surgical procedures. Some authors highlighted its advantages in reducing operative time, blood loss, and damages to surrounding tissue. In our study, we compared the results obtained during parotidectomy using the HS with the traditional approach to determine the(More)
BACKGROUND Localized bone defects in the maxilla are commonly reconstructed with autologous mono-cortical bone blocks prior to the placement of dental implants. This study presents a clinical, histological and histomorphometric analysis on the use of mandibular ramus block grafts for ridge augmentation. MATERIALS AND METHODS mono-cortical bone blocks from(More)
The authors report the histological features found around three non-submerged titanium plasma-sprayed implants retrieved, after a 10-month loading period, from an autopsy case. At the time of implant insertion, the clinician had noted a wide vestibular dehiscence of the central implant, and it was decided to use a bioabsorbable membrane for guided bone(More)
Squamous odontogenic tumor (SOT) is a benign, locally infiltrative intraosseous tumor composed of well-differentiated squamous epithelium in a fibrous stroma. It seems to derive from the epithelial rests of Malassez in the periodontal ligament space. It presents an odontogenic origin, involving both the upper and lower maxillary bone, mainly areas without(More)
BACKGROUND Insufficient bone volume in the posterior maxilla can be a major problem when placing dental implants. One of the goals of sinus augmentation procedures is the creation of sufficient volume of vital bone for the subsequent insertion and complete osseointegration of implants placed in the posterior maxilla. The aim of the present study was a(More)
Gorlin-Goltz Syndrome (Nevoid Basal Cell Carcinoma Syndrome) is a well-known disorder with distinctive symptoms, which are studied since the 1960s. This is an hereditary disease, with autosomal dominant trait, characterised by high penetration and variable expressivity. Only recently it has been ascertained that it is caused by the aberration of the long(More)
BACKGROUND Immediate implant placement after tooth extraction is a predictable solution in various clinical situations. The purpose of this study was to evaluate the predictability of a treatment, including the placement of implants, using a modified insertion technique at the time of maxillary molar extraction. MATERIALS Sixty-eight patients with a total(More)
