Abstract
Aim: To report a clinical case using the bilateral osseodensification technique for lifting the maxillary sinus and implants placement. Case report: In total, 4 implants were placed in order to rehabilitate the patient, including 3 external hexagons. The patient had not enough bone height and width available for the placement of implants (classified for subantral technique surgical - SA-3), by the traditional technique and, therefore, the bilateral osseodensification technique was recommended for rehabilitation in the posterior region of the maxilla, with simultaneous placement of endosseous implants. The osseodensification technique consists of using drills with a biomechanical approach and technology for bone preparation that is different from the conventional technique. The bone tissue was compacted and autografted simultaneously towards the outside, expanding from the osteotomy. The short-term results showed the formation of dense bone at the implants` apex, reducing the osseointegration period from 6 to 4 months and enabling the achievement of primary stability in bone of low height and low density. Final considerations: Based on the clinical and radiographic results, it can be afirmed that the osseodensification technique is efficient for posterior regions of the maxillary classified for subantral technique surgical (SA-3), providing adequate osseointegration of endosteal implants after 4 months.
