Minimally Invasive Maxillary Sinus Elevation with Implant Placement: The Indirect Approach

Introduction: Pneumatization of the maxillary sinus following tooth extraction is a common phenomenon in the posterior maxilla, often leading to considerable loss of alveolar bone height. To address this limitation, sinus lift procedures are employed. Sinus floor elevation may be carried out using either the indirect (transcrestal) or direct (lateral) approach.  Case Report: A 35-year-old female patient presented to the Department of Prosthodontics, Crown and Bridge at Jaipur Dental College with a chief complaint of missing teeth in the upper left back tooth region for 7 months and sought a fixed treatment. The buccal and palatal flaps were adequately mobilized to provide a clear field of the alveolar crest. First drill was made till 5mm depth followed by osteotome hammering till 10mm and continued till 4.3mm of last drill till 5mm and osteotome hammering till 10mm. Implant placement done of size 4.5mm*10mm followed by placement of cover screw.  Discussion: The indirect sinus lift shows high implant survival rates and predictable outcomes when applied in appropriately selected cases.
