Abstract

Background and objectives: To evaluate whether sinus augmentation, using a minimally invasive implant device, via a non‐submerged surgical approach, might negatively influence the outcome. Materials and Methods: A retrospective cohort study was conducted by evaluating patients’ files, classifying them into two groups. Fifty patients (22 men 28 women) were included in the study, 25 in each group. The use of an implant device based on residual alveolar ridge height for sinus augmentation, radiographic evaluation, insertion torque, membrane perforation, post‐operative healing, and a minimum of 12 months follow‐up were evaluated. Results: The mean residual alveolar ridge height was 5.4 mm for the non‐submerged group and 4.2 mm for the submerged group. There were no intraoperative or postoperative complications (including membrane perforations). The mean insertion torque was 45 N/cm for the study group and 20 N/cm for the control group. Complete soft tissue healing was observed within three weeks. Mean bone gain height was 8 mm for the study and 9.3 mm for the control group. All implants osseointegrated after 6–9 months of healing time. Mean follow‐up was 17.5 months, range 12–36 months. Marginal bone loss at last follow‐up was not statistically significantly different: 1 mm in the non‐submerged vs. 1.2 mm in the submerged group. Conclusions: Submerged and non‐submerged healing following maxillary sinus augmentation was comparable provided residual alveolar ridge height >5 mm and insertion torque >25 N/cm.
