Brief summary

It is assumed that the reduction of the flap dimension could provide a reduction of surgical time, post surgical complications and patient's discomfort when compared with the traditional surgical approach.

Detailed description

16 edentulous patients in maxillary posterior area were treated with a bilateral sinus lift procedure. Once enrolled in the study impressions were realised and the radiographic stent prepared, with radio-opaque references fixed in the positions where the implants should be inserted. Pre-surgical CT scan was executed after placing the stent in its proper position in patient's mouth. If no surgical contra-indications were detected at CT evaluation, patients were involved in the study.

Interventions

PROCEDUREflap

after flap incision , the sinus cavity was opened and then the membrane raised up

Design outcomes

Primary

Measure	Time frame	Description
height of augmented bone obtained	6 months	the height of the gained bone was recorded by using the control CT scan, realized after 6 months of follow up

Secondary

Measure	Time frame	Description
Duration of the surgery	1 day	both total and partial times of different surgical steps were recorded
Post surgical patient's discomfort	2 weeks	all patients were asked to fill out a VAS scale, graduated from 1 (minimal pain ) to 10 ( maximum pain)
