Amnion Chorion Membrane and Oroantral Communication

An oroantral communication is a relatively common yet, serious complication following the extraction of posterior maxillary teeth because of their close relationship to the maxillary sinus. Several surgical techniques exist for the repair of oroantral communication, including local and free flaps, tissue expansion, allogenic tissue, and biomaterials. The present study aims to evaluate the use of the BioXclude amnion chorion membrane in the repair of oroantral communication.

This study will be performed on ten patients who have oroantral communication after extracting posterior maxillary teeth. The oroantral communication will be repaired by using the BioXclude amnion chorion membrane.

The OAC will be closed by the Bioxclude ACM Amnion chorion membrane which is applied over the extraction socket then supported with a buccal advanced flap.

Surgery will be considered successful in case of negative nose-blowing 1-month postoperatively, absence of infection, absence of dehiscence or other healing complication

Post-operative pain measure by patients rating 12 h after surgery using visual analogue scale (VAS) of 100 unit on three-point scale with: 0-34 as mild pain, 35 - 64 as moderate pain and 65 - 100 as severe pain

Evaluation of bone formation at the communication site by computed tomography will be measured at 3 months and 6 months post operatively

Inclusion Criteria: Patients should be free of any relevant systemic diseases. Patients with recent oroantral communication (O.A.C) (24:72) hours . Good oral hygiene Exclusion Criteria: An immune compromised state. Previous sinus disease. History of sinus surgery. Presence of intra-antral foreign bodies and need for cold well-luc procedure. Presence of intra-sinus pathology
