Overview

This study aims to describe a new approach for the reconstruction of the alveolar process in the sinus area. This minimally invasive approach will access the maxillary sinus through the alveolar process, elevating the sinus membrane in the area immediately above it. The regeneration may be achieved in the specific area required for dental implant placement, reducing the morbidity of the procedure.

Eligibility

Inclusion Criteria:

• Patient older than 18 years.
• Plaque index and bleeding index less than 30%.
• Invagination of the sinus cavity in the interradicular area of the upper first molar.
• Upper first molar not restorable and with height of the interradicular remnant less than 5 mm.

Exclusion Criteria:

• Presence of systemic disease contraindicating the intervention.
• Pregnant women.
