Proximity of maxillary molar teeth roots to the maxillary sinus floor can potentiate oroantral communication (OAC) after extraction. Considering the defect size and situation, surgical treatment may become essential. Surgical treatment modalities are variable and would be indicated in special clinical circumstances.In this article, a chronic case of OAC with a size of 25 × 15 mm(2) in a 30-year old man with history of heavy smoking and drug abuse was treated with combination of buccal fat pad (for covering sinus floor), coronoid process pedicled on temporalis flap, and mucosal closure. There was no complication during and after operation. Short- and long-term follow-up revealed success of this novel technique despite the patient's poor compliance.

Real-time surgical navigation systems (dynamic computer-aided surgery, d-CAIS) and static guided surgery (static computer-aided surgery, s-CAIS) have been shown to enhance the accuracy of zygomatic implant (ZI) placement. The objective of this systematic review was to evaluate and compare the accuracy and risk of complications associated with d-CAIS and s-CAIS in ZI placement. A systematic review of published studies involving more than 4 patients was conducted to assess and compare the accuracy of d-CAIS and s-CAIS in zygomatic implant placement.

Oroantral fistula (OAF) represents the pathological communication between the oral cavity and maxillary sinus. This condition arises when the structural integrity of the maxillary sinus floor is compromised, resulting in a direct conduit between the sinus and the oral cavity. A less prevalent yet clinically significant contributor to the formation of OAF is chronic osteomyelitis of the maxilla.

Background: Oroantral fistula (OAF) is a pathological channel formed between the oral cavity and the maxillary sinus. A large size of OAF (≥5 mm) increases the risk of surgical failure, and an optimal surgical approach should be cautiously selected.
Objective: This study aims to characterize the application of nasal endoscopy and buccal fat pad (BFP) flaps to repair large OAFs in patients with odontogenic maxillary sinusitis (OMS).

Background: Maxillary Schneiderian membrane (SM) perforation is one of the complications of maxillary sinus (MS) augmentation. The aim of the present study was to analyse cone beam computed tomography (CBCT) findings to identify prognostic factors for SM perforation.
Materials And Methods: 50 CBCT scans were recruit for the analysis, 39 were suitable for analysis and met the inclusion criteria.

Article Synopsis
- * The procedure involves lifting the buccal fat pad and sinus mucosa under general anesthesia, then filling the resulting gap with a biomaterial that supports osseointegration.
- * With sufficient surgical experience, this method is considered a reliable solution for successful dental implant placement in the maxillary posterior area.
