Short Implant in Maxillary Sinus Elevation: A Mid-term Clinical Observation

doi:10.13701/j.cnki.kqyxyj.2018.07.012

Abstract

Abstract: Objective: To evaluate the clinical and radiographic outcome of osteotome sinus floor elevation (OSFE) procedure and immediate short implants placement after 4-6 years. Methods: The study included 16 consecutive patients. A total of 26 short implants were inserted with the OSFE technique. The indication for sinus floor elevation was that the residual bone height was less than 3mm. Results: The survival rate was 96.2% in 5 years. The average mesial marginal bone change was (0.14±0.15) mm, and the average distal marginal bone change was (-0.03±0.17) mm. Soft tissue was all in good condition. The distal marginal bone change was different between splinted crown restoration and single crown restoration, free and non-free end implants. Conclusion: This study shows that the OSFE with immediate short implant placement could produce optimistic result in the treatment of patients with severely atrophy maxilla during 5-year following up.
