Crestal approach for maxillary sinus augmentation by using navigation surgical guide: case report

Abstract

Objective : The purpose of this study is to introduce a novel method for safe and precise crestal approach technique for sinus augmentation and implant placement using digital technology. The study further aims to verify effectiveness of the technique in implant placement and sinus augmentation.Materials and Methods : 5 patients who needed crestal approach sinus augmentation for implant placement were collected. There were more than 4mm residual bone in those patients. Intraoral image taking and CBCT taking were performed for digital planning. Digital planning was conducted for crestal approach sinus augmentation and implant placement. 2 navigation surgical guides(crestal/implant) were fabricated for each patient.Results : 10 implants were placed in the patients without specific problems by using crestal approach surgical guide and implant surgical guide.Conclusion : Crestal approach for maxillary sinus augmentation by using navigation surgical guide would be a reliable treat-ment option for successful implant placement in insufficient residual bone height of maxilla.
