In this single-blind study, sealed opaque envelopes will be used to conceal the sequencing. The person responsible for data collection is blind to group allocation and the type of intervention. 2 Teeth implants. Intervention 1: Intervention group: Intervention group I will receive sinus lift surgery for single posterior maxillary implants with a residual alveolar bone thickness of 2-4 mm and 5 bony walls (medial, lateral, mesial, distal, and inferior). Intervention 2: Intervention group: Intervention group II will receive sinus lift surgery for multiple posterior maxillary implants with a residual alveolar bone thickness of 2-4 mm and 3 bony walls (medial, lateral, and inferior).
