•1. More than 20 teeth present
•2. CBCT scans clearly showing the roots of the posterior maxillary teeth or edentulous ridge, the maxillary sinus floor, the zygomatic processes, and the inferior orbital margins.
•3.CBCT scans with atleast 6 months post extraction maxillary posterior partially edentulous site but edentulousness of not more than 2 years.
•4.CBCT scans having unilateral missing maxillary posterior tooth or teeth with contralateral tooth or teeth.

•1.History of nasal and sinus diseases, periodontitis or diseases affecting the bone.
•2.Pathological changes observed in the target region, including maxillary sinus mucosal thickening, maxillary sinus inflammation, cyst or tumors, malformations, and maxillary fractures.
•3.History of orthodontic therapy, periodontal surgery, maxillary sinus surgery, alveolar ridge preservation, maxillary sinus augmentation.
•4.Obvious anatomic abnormalities including buccal ledging and exostoses.
•5.Scans with excessive scatter due to the presence of existing restorations or implants.
