Long‐term outcomes of lateral sinus floor elevation: A machine‐learning analysis, systematic review, and meta‐analysis of predictive factors

Implants placed after LSFE exhibit high 5-13-year survival (96 %). Use of bone graft materials and their mixtures yield more favorable outcomes compared to Graftless protocol, whereas RBH < 4 mm and smoking significantly impair implant survival. Barrier-membrane coverage is advisable for smokers and short-RBH sites. Despite the long-term nature of this review (≥5 years of follow-up), most failures occur within the first three years of function, underscoring the need for intensified monitoring during this early phase.
