“…Furthermore, clinical indications for maxillary sinus floor elevation with transcrestal approach have greatly increased in recent years (Block, 2016; Stacchi et al, 2020). Several studies explored the possibility to perform one‐stage or two‐stage transcrestal sinus augmentation even in sites with residual bone height ≤5 mm, resulting in minimal invasivity and excellent implant survival rate (Bernardello et al, 2011; Gonzalez et al, 2014; Lin et al, 2020; Lombardi et al, 2017; Sisti et al, 2012; Sonoda et al, 2020; Stacchi et al, 2018; Toffler, 2004).…”

Objective Clinical indications for maxillary sinus floor elevation with transcrestal techniques have increased in recent years even in sites with minimal residual bone height (RBH). Nevertheless, limited information is currently available on incidence of intraoperative complications and early implant failure in these cases. Material and Methods This retrospective multicenter study was performed on anonymized clinical and radiographic records of patients who underwent transcrestal sinus floor elevation in seven clinical centers. Influence of different factors related to patient, and sinus anatomy and surgical technique on the incidence of intraoperative complications and early implant failure rate after transcrestal sinus lift were investigated. Results A total of 430 patients treated with transcrestal sinus floor elevation for single‐implant insertion in sites with RBH ≤5 mm were included in the final analysis. After 1 year of loading, 418 implants of 430 were satisfactorily in function. Early implant failure was recorded in 12 cases (2.8%); results were significantly associated with the presence of large sinus cavities and with the occurrence of membrane perforation. The following adverse events were recorded: membrane perforation (7.2%), acute sinusitis (0.9%), implant displacement into the sinus cavity (0.7%), oro‐antral fistula (0.2%), and benign paroxysmal positional vertigo (0.5% of osteotome cases). A strong direct correlation between sinus membrane perforation and bucco‐palatal sinus width (p = .000) was demonstrated. Conclusions Early implant failure after transcrestal sinus elevation showed significant direct correlation with bucco‐palatal maxillary sinus width and the presence of membrane perforation. Sinus membrane perforation was strongly associated with bucco‐palatal sinus width (extremely low perforation rate in narrow and much higher incidence in wide sinuses).

“…First, the deep learning model predicted classes consistent with the ground truth in cases in which the residual bone was clearly abundant, barely sufficient, or compromised, but it predicted incorrect classes in borderline cases. In cases of the residual bone on the borderline of the classes, clinicians choose an appropriate surgical approach by considering other factors, such as the anatomy of the maxillary sinus, patients' systemic conditions, and their own preference for less invasive techniques 54 , 55 . A more advanced deep learning model based on multi-modal inputs needs to be developed to incorporate data other than the residual bone volume in CBCT images so that it can provide more suitable treatment plans for borderline cases.…”

The objective of this study was to automatically classify surgical plans for maxillary sinus floor augmentation in implant placement at the maxillary posterior edentulous region using a 3D distance-guided network on CBCT images. We applied a modified ABC classification method consisting of five surgical approaches for the deep learning model. The proposed deep learning model (SinusC-Net) consisted of two stages of detection and classification according to the modified classification method. In detection, five landmarks on CBCT images were automatically detected using a volumetric regression network; in classification, the CBCT images were automatically classified as to the five surgical approaches using a 3D distance-guided network. The mean MRE for landmark detection was 0.87 mm, and SDR for 2 mm or lower, 95.47%. The mean accuracy, sensitivity, specificity, and AUC for classification by the SinusC-Net were 0.97, 0.92, 0.98, and 0.95, respectively. The deep learning model using 3D distance-guidance demonstrated accurate detection of 3D anatomical landmarks, and automatic and accurate classification of surgical approaches for sinus floor augmentation in implant placement at the maxillary posterior edentulous region.

“…Transalveolar maxillary sinus elevation methods are preferred to the lateral window technique because of less flap reflection and fewer complications such as membrane perforation and bleeding, but case selection remains a crucial point. 8 , 9 After the standard Summer’s technique for transalveolar approach, 11 several modifications have been described to improve the shortcomings of this technique, which are described in detail in this review. One aim of all these techniques is to reduce or eliminate hammering and consequently decrease the patients’ discomfort.…”

“…8 The main complications with the lateral window approach include Schneiderian membrane perforation, bleeding, implant displacement into the sinus, sinusitis, damage to the adjacent teeth, and ostium obstruction. 8,9 The implants could be placed right after the sinus floor elevation (simultaneous) or after the initial healing of the prepared site (staged). 7 The crestal approach was first suggested by Tatum, who used a "socket former" to create a "greenstick fracture" in the sinus floor.…”

Dental implant treatment in the posterior maxilla encounters bone quality and quantity problems. Sinus elevation is a predictable technique to overcome height deficiency in this area. Transalveolar sinus elevation is a technique that is less invasive and less time-consuming, first introduced for ridges with at least 5 mm of bone height. Many modifications and innovative equipment have been introduced for this technique. This review aimed to explain the modifications of this technique with their indications and benefits. An exhaustive search in PubMed Central and Scopus electronic databases was performed until December 2020. Articles were selected that introduced new techniques for the transalveolar maxillary sinus approach that had clinical cases with full texts available in the English language. Finally, twenty-six articles were included. The data were categorized and discussed in five groups, including expansion-based techniques, drill-based techniques, hydraulic pressure techniques, piezoelectric surgery, and balloon techniques. The operator’s choice for transalveolar approach techniques for sinus floor elevation can be based on the clinician’s skill, bone volume, and access to equipment. If possible, a technique with simultaneous implant placement should be preferred.
