“…OSFE with Collagen bone graft application is accompanied with high patient satisfaction, minimal postoperative pain, and less fear of going through similar surgical procedures [40]. Collagen proved to stimulate bone formation in bone defects, nonhealing extraction sockets, and with OSFE with immediate implant placement [20,22,41,42]. Moreover, our hypothesis that the presence of CGF played a role to overcome the degradation and high absorption rate of collagen by stimulating later osteogenesis and bone formation through PI3K/AKT signaling pathway, more investigations are needed to verify this pathway in further researches.…”

Background: Osteotome sinus floor elevation (OSFE) procedure with immediate implant placement proved to be efficient procedure in the atrophic maxilla, where bone regeneration is required the most. The purpose of this retrospective study was to radiologically evaluate collagen with Concentrated Growth Factor (CGF) as grafting materials for OSFE with simultaneously implant placement in the atrophic maxilla after one year of being functional loaded. Methods: 126 implants were inserted for 123 patients. Patients included in our criteria with Residual Bone Height (RBH) ≤ 5 underwent OSFE procedure and immediate implant placement with different grafting materials. Group A with no grafting materials, Group B with Bio-Oss bone graft, and Group C with Bio-Oss collagen and CGF. Radiographic measurements assessed at 4 time points follow up after surgery were secondary outcome variables, in addition to Implant Stability Quotient (ISQ) and Bone density (B). Indicators of bone formation were compared at different time points. Appropriate statistics were computed, and statistical significance was indicated by P value 0.05 for all tests. Results: Total Implants Survival Rate (ISR). was 96%. There was a significant positive relationship between RBH and ISR, [r (126) = .359, p = .000]. Higher indicators for endo-sinus bone gain were recorded in both grafted groups. Total Bone Resorption (TBR1) and (TBR2)were significantly decreased in both grafted groups compared to non-grafted group (P = .004, P = .000). (Graft size) D was a positive predictor for ISR at three time points. D0, (odds ratio [OR] 8.06; 95% CI 1.59 to 38.24; P = .010). D1, (OR 96.58; 95% CI 1.69 to 5.52; P = .027). D2, (OR 4.97; 95% CI 1.29 to 19.19; P = .020) Conclusion: The combination of collagen with CGF as grafting material is a reliable protocol after OSFE with simultaneously implant placement in the atrophic maxilla.

“…A previous study showed that ABF depended mainly on space maintenance below the elevated sinus membrane. [25] A total of 87%, 82.9%, and 18.7% of implants showed ABF one year after implantation while grafting with DBBM, PDGF, and without any grafting material, respectively. [26-28] Therefore, the space-maintaining ability of the present grafting protocol seemed not as good as that of DBBM and PDGF but better than that of the no graft group.…”

Objectives This study aimed to assess the bone augmentation potential and safety of rhBMP-2/ACS combined with L-PRF in crestal sinus lift. Materials and Methods This study applied a retrospective study design. We recruited patients undergoing crestal sinus lifting in combination with rhBMP-2/ACS and L-PRF one year after implantation. The bone augmentation potential was radiographically assessed by measuring the height, volume, and cancellous density of newly formed bone. The safety of this grafting protocol was evaluated through self-reported complications. Results Fourteen implants were installed simultaneously following sinus membrane elevation. All 14 implants fulfilled the success criteria one year after implantation. No complications were reported by the subjects. The average gained bone height and average gained bone volume were 3.2 mm and 435.7 mm3, respectively. Cancellous bone density in the sagittal plane on cone beam computed tomography images was significantly lower than that in the coronal or transverse plane. Conclusions This grafting protocol showed promising bone augmentation ability and excellent safety in crestal sinus floor augmentation. Clinical Relevance The combination of rhBMP-2 and L-PRF provides a promising grafting protocol for maxillary sinus floor elevation. Clinical trial This study has been registered in ChiCTR (ChiCTR2200063426) on Sep. 6, 2022.

“…Some implants may suffer apical non‐coverage, especially in cases with low residual bone height (RBH) (Pjetursson, Ignjatovic, et al., 2009). Various patient and operator factors, such as the anatomy of the maxillary sinus, surgical expertise, and instrument selection, may also influence bone augmentation outcomes (Huang, Ban, et al., 2021). In recent years, anatomical factors have gained increased attention (Lin et al., 2022) for their potential impact on the endo‐sinus space preservation beneath the elevated Schneiderian membrane (Dahlin et al., 1988) and endo‐sinus bone remodeling (Thor et al., 2007).…”

ObjectivesTo identify the risk indicators and develop and validate a nomogram prediction model of implant apical non‐coverage by comprehensively analyzing clinical and radiographic factors in bone‐added transcrestal sinus floor elevation (TSFE).Material and MethodsA total of 260 implants in 195 patients receiving bone‐added TSFE were included in the study. The population was divided into a development (180 implants) and a validation (80 implants) cohort. According to 6 months post‐surgery radiographic images, implants were categorized as “apical non‐coverage” or “apical covered.” The association of risk factors including clinical and radiographic parameters with implant apical non‐coverage was assessed using regression analyses. A nomogram prediction model was developed, and its validation and discriminatory ability were analyzed.ResultsThe nomogram predicting bone‐added TSFE's simultaneously placed implant's apex non‐coverage after 6 months. This study revealed that sinus angle, endo‐sinus bone gain, implant protrusion length, graft contact walls, and distal angle were predictors of implant apical non‐coverage. The generated nomogram showed a strong predictive capability (area under the curve [AUC] = 0.845), confirmed by internal validation using 10‐fold cross‐validation (Median AUC of 0.870) and temporal validation (AUC = 0.854). The calibration curve and decision curve analysis demonstrated good performance and high net benefit of the nomogram, respectively.ConclusionsThe clinical implementation of the present nomogram is suitable for predicting the apex non‐coverage of implants placed simultaneously with bone‐added TSFE after 6 months.
