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.
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.
all the involved patients were edentulous in the maxillary posterior area , bilaterally, with a residual bone heigh of less then 4 mm; for this reason they required a surgical bone reconstruction for implant placement.
Exclusion Criteria:
Horizontal incision was realised in alveolar mucosa, in order to obtain the exposure of the lateral wall of the maxillary sinus, thus accessing the sinus cavity
Procedure: flap
Trapezoidal flap was realised, using a crestal incision and two deep vertical incisions extended in the fornix to expose the lateral wall of the maxillary sinus
Procedure: flap
after flap incision , the sinus cavity was opened and then the membrane raised up
Also known as: surgical approach, Sinus augmentation
height of augmented bone obtained
the height of the gained bone was recorded by using the control CT scan, realized after 6 months of follow up
Time frame: 6 months
Duration of the surgery
both total and partial times of different surgical steps were recorded
Time frame: 1 day
Post surgical patient's discomfort
all patients were asked to fill out a VAS scale, graduated from 1 (minimal pain ) to 10 ( maximum pain)
Time frame: 2 weeks
