Sinus Augmentation with Simultaneous, Non-Submerged, Implant Placement Using a Minimally Invasive Hydraulic Technique

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.

Management of Schneiderian membrane perforations during maxillary sinus floor augmentation with lateral approach in relation to subsequent implant survival rates: a systematic review and meta-analysis

“…No lateral approach (solely) Chaushu et al [43], Yoko Oba et al [44], Giudice et al [45], Attar et al [46], Becker ST et al [12]. beneath previously perforated and repaired membranes, obtaining a survival rate of 97.68%, while 2495 implants were placed under intact sinus membranes obtaining a survival rate of 98.88%.…”

Comparative microcomputed tomography and histological analysis of the effects of a horizontal platelet‐rich fibrin bone block on maxillary sinus augmentation: A preclinical in vivo study

“…By adding liquid H‐PRF to the mixture of solid H‐PRF fragments and DBBM, a moldable sticky bone block forms after solidification. The present study showed that the H‐PRF bone block has certain elastic and compressive properties, with a higher ability to promote osteogenesis in osteoblasts in vitro, but its effect on bone regeneration after maxillary sinus elevation has not been proven in vivo (Chaushu et al, 2020).…”

Effect of Sinus Floor Augmentation with Platelet-Rich Fibrin Versus Allogeneic Bone Graft on Stability of One-Stage Dental Implants: A Split-Mouth Randomized Clinical Trial

“…Stability without micromovement is imperative for osseointegration of dental implants [ 1 ]. Generally, a 6- to 9-month healing period is required for implant placement if simultaneous with sinus floor augmentation [ 2 ]; however, surface treatments of new dental implants have shortened this period to approximately 6 months [ 3 ]. Implant stability depends on many factors, among which quality of bone plays a fundamental role.…”
