About

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.

Full 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.

Enrollment: 16 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• patient edentulous in the maxillary posterior area on both left and right side
• residual bone height in the maxillary premolar and molar region less than 4mm

Exclusion criteria

• history of systemic diseases that would contraindicate surgical treatment

Trial design

16 participants in 2 patient groups

test side ( horizontal flap)

Description:

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

Treatment:

Procedure: flap

control side ( standard flap)

Description:

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

Treatment:

Procedure: flap
