Introduction:

Dental implant placement simultaneous with maxillary sinus lifting on ridges with severe resorption < 4 mm is a sensitive surgical technique that shortens the duration of interventions. However, it is considered to be operator dependent, and may cause complications if not appropriately managed.

Objective:

After 24 months of functional load, evaluate the stability of the peri-implant tissue of a dental implant placed simultaneously with maxillary sinus lifting on an alveolar ridge with severe bone resorption.

Case presentation:

A case is presented of a male 62-year-old patient with severe bone resorption in the area of the first upper right molar. Analysis of the diagnostic means and scientific evidence involved led to placement of a dental implant simultaneous with maxillary sinus lifting (lateral window technique). The second surgical stage was performed four months later. A zirconium crown was finally placed, and a 24-month follow-up period was started.

Conclusions:

With a good diagnosis, appropriate surgical management, patient cooperation and periodic controls, it is a safe technique that ensures the stability of peri-implant tissue.
