Brief Summary

Maxillary sinus augmentation is one of the most performed procedures to increase the bone quantity of the atrophic maxilla in order to allow implant placement. The aim of the present case series was to describe a surgical protocol to perform maxillary sinus augmentation with the "bone lid technique", and its outcomes in a cohort of patients eligible for the procedure.

Conditions

Maxillary Deficiency

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: PROSPECTIVE

Interventions

Bone lid repositioning in course of sinus lift

A full-thickness flap was elevated to access the lateral maxillary bone wall. Subsequently, a lateral access window was prepared using a piezoelectric device with specific bone tips, delimitating a trapezoidal bone lid.

Once the antrostomy was completed, the bone lid was gently removed with a Lucas surgical curette and anatomical tweezers, with great care to avoid damages to the Schneiderian membrane. The Schneiderian membrane was detached from the bone layer using specific sinus curettes. In case of sinus membrane perforation, the membrane was raised in all directions. All clinical cases received a cortical bone lamina to avoid graft particles displacement in the maxillary sinus. The elevated space was filled with chips of cortico-spongious bone. The antrostomy was then covered with the bone lid (osteotomy window), previously removed and preserved in physiological solution and fixed in the original anatomical position with a surgical glue. The flap was then repositioned and sutured.
