Piezosurgery in the maxillary sinus augmentation procedure.
No full textOBJECTIVES: The aim of this study was to investigate the incidence of the perforations of the Schneiderian membrane and the time spent for the antrostomy,separation and elevation of the sinus membrane related to the area of the bony window, using piezosurgery(Easy Surgery-BioSAFIN-Ancona-Italy). METHODS: At the Department of Oral Sciences of “Sapienza” University of Rome were selected 40 patients,19 females and 21 males, mean age was 53,6 years(range 42-67),total edentulous in the posterior maxilla, in the period between June 2005 and January 2008.The residual alveolar ridge height did not exceed 4mm. All patients underwent to maxillary sinus augmentation procedure , using piezosurgery for the osteotomy of the bony window (insert-OT1), sinus membrane separation (insert-EL1) and sinus membrane elevation (insert-EL2) .For each case treated has been evaluated the area of the bony window and the time necessary for the antrostomy, separation and elevation of the sinus membrane. Was recorded also the occurrence of Schneiderian membrane perforation. RESULTS:The average time necessary for the surgical procedure was 10.32 min (SD: 2,093) with 96.78 mm2 mean surface extension of the bony window . Seven Schneiderian membrane perforations were recorded with an incidence of 17.5%, resolved with the use of a resorbable membrane. CONCLUSION: Piezoelectric surgery allows to simplify the technique of the maxillary sinus lift by reducing the risk of perforation of the membrane, but due to less cutting efficiency, results in an increase in operative time compared with rotary instruments
Trasporto e distribuzione delle merci in ambito urbano. Un progetto innovativo di City Logistics attraverso l’applicazione di un Transit Point Intermodale
No full textRELATIONSHIP BETWEEN THE MAXILLARY CANINES IN AN ECTOPIC AND VARIATION OF THE DIAMETER OF THE TEETH
Full text linkAim. A tooth is impacted when its apex is formed but does not erupt as expected during the
physiological timeframe of eruption. Maxillary canines, after the third molars are the teeth that more
frequently show alterations of their eruptive process.. Maxillary canines can be positioned in ectopic
palatal or buccal position. In recent years, an extensive search of the literature has shown a correlation
between the palatal ectopic eruption of the canine and size of the dental elements reduced. Purpose of
the study was to investigate a relationship between ectopic eruption of the canine oral, dental crowding
and increased diameter of the teeth
Le metodiche CAD-CAM nella costruzione di pilastri protesici implantari in titanio.
No full textTo point out the use of CAD-CAM techniques in the construction of titanium customized abutment. MATERIALS AND METHODS. After evaluating the different uses of CAD-CAM techniques in dentistry over the past twenty years, the authors describe the pros and cons of currently available abutments: stock abutment, cast custom abutment (full and UCLA) and CAD-CAM abutment. After reviewing the literature about discrepancies in abutment-implant connection and freedom of rotation of CAD-CAM customized titanium abutment, the authors describe the construction of CAD-CAM abutment step by step from impression taking to finishing and polishing. CONCLUSIONS. The latest scanning technology and CADCAM production systems enable the construction of extremely accurate and perfectly fitting titanium abutments
