An observational study in Partial-edentulism and Osteotome Sinus Lift, sponsored by Hospital of Stomatology, Sun Yat-Sen University. Status unknown at 1 site in China. Per ClinicalTrials.gov, last updated 2021-02-23.
Sponsored by Hospital of Stomatology, Sun Yat-Sen University · Observational
The contour of maxillary sinus matters in osteotome sinus elevation. So does the implant intruding angle between the axis of the implant and the tangent line of the sinus floor contour. The investigators have been engaged in studying the relationship between the outcome of bone formation and the intruding angle, which could guide our clinical decision-making.
