Abstract:
The presence of sinus septa, common anatomic structures of the maxillary sinus, may increase the incidence of surgical complications during sinus floor elevation. This article introduces a digital protocol for achieving safe and precise sinus floor elevation with an individualized surgical template that combines implant placement and the lateral sinus window technique. This technique facilitates precise preplanning and preparation of the lateral osteotomy window and the implant site and reduces surgical complications, shortens surgical duration, and improves patient-related outcomes.
