Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

test side ( horizontal flap)

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

flap

Intervention Type PROCEDURE

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

control side ( standard 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

flap

Intervention Type PROCEDURE

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