Implant placement in the posterior part of the maxilla is frequently compromised due to atrophy of the alveolar process. Therefore, alveolar ridge augmentation is frequently necessary before or in conjunction with implant placement. The most commonly used method to augment the maxillary premolar and molar region involves the maxillary sinus floor augmentation (MSFA) with autogenous bone graft or a bone substitute. However, the use of autogenous bone grafts is associated with risk at the donor site morbidity and unpredictable graft resorption. Consequently, short implants are used increasingly to eliminate the need for bone augmentation. However, long-term studies comparing short implants and standard implants in conjunction with MSFA supporting single crown restoration in the posterior maxilla are missing. The primary outcome measures include survival of implant and suprastructures, peri-implant marginal bone level (MBL), professional evaluation of the suprastructure and soft tissue using pink esthetic score (PES) and white esthetic score (WES), patient satisfaction using visual analogue scale (VAS), and oral health related quality of life using oral health impact profile (OHIP-14) questionnaire. Secondary outcome measure include evaluation of the complication rate related to the two treatment modalities.
