About

Ten patients with displaced root in maxillary sinus will be included in this study. the root will be recieved via lateral bony window in maxillary sinus wall using peizoelectric device then the bony window will be repositioned in its place.The patients will be received, clinically and radiologically examined, managed and followed up at the Oral and Maxillofacial surgery Department, Faculty of Dentistry, Tanta University

Full description

Purpose: This study is designed to allow removal of displaced root from maxillary sinus with minimal surgical injury and simultaneous preservation of the integrity of the lateral wall of maxillary sinus by repositioning of osteotomized lateral bony window.

Materials & Methods: Ten patients with displaced root in maxillary sinus will be included in this study.

surgical procedure: A full thickness flap will be elevated to expose the lateral wall of the sinus and a rectangular bony window will be done, then the sinus lining will be incised, the displaced root will be delivered, the bony window will be repositioned, and the flap will be sutured.

Preoperative evaluation: The patients will be evaluated clinically for presence of inflammation, infection or oroantral communication and radiographically using computed tomography (CT) scan to identify the position of the displaced root.

Postoperative evaluation: The patients will be evaluated clinically each week for one month regarding to healing, presence of infection, inflammation. Radiographically, immediate panoramic view to evaluate the position of bony window and four months later to evaluate bone healing CT scan.

Enrollment: 10 patients

Sex: All

Ages: 20 to 55 years old

Volunteers: Accepts Healthy Volunteers

lateral bony window in maxillary sinus

Experimental group

Description:

a displaced root in maxillary sinus which will be removed through a rectangular bony window will be done on the lateral wall of sinus using piezo-electric device after elevation of a full thickness mucoperiosteal flap, then the bony window will be repositioned, and the flap will be sutured.

Treatment:

Device: lateral bony window
