Osteotome Sinus Floor Elevation and Simultaneous Placement of Implants – A 1-Year Retrospective Study with Astra Tech Implants

ABSTRACT Aim The aim of the study was to evaluate retrospectively maxillary sinus functions and complications by using generally accepted diagnostic criteria with lateral window and osteotome sinus floor elevation (OSFE) procedures followed by dental implants placement. Materials and methods A group of 60 patients in whom a SFE with the two procedures (lateral window and OSFE) followed by dental implants placement had been performed were evaluated retrospectively for sinus functions and complications from the time of procedure up to 24 months using a questionnaire, conventional clinical and radiographic examination. Results Number of patients suffered dizziness accompanied by nausea immediately after OSFE was more than the lateral window procedure and the symptoms disappeared within 2 to 4 weeks. Maxillary sinus membrane perforations occurred and small for 4 out of 79 procedures, two cases for OSFE and two for lateral window procedure had been repaired. No more complications had been detected for all the patients up to 24 months. Conclusion Based on the results of this study, SFE with lateral window and osteotome procedures followed by dental implants placement did not interfere with maxillary sinus function and no obvious complications had been detected up to 24 months. Clinical significance The clinician performs SFE with either lateral window or osteotome procedures needs to understand the difficulties and morbidity arising in the event of complications and must be able to correctly judge the individual risk and the presence of modifying factors that may cause these complications.

Osteotome Sinus Floor Elevation

Abstract Background This study analyzed the influence of implant protrusion length (IPL) on the possible factors that affect the long-term outcomes utilizing non-grafting osteotome sinus floor elevation (OSFE) with simultaneous implant placement, and to explore the optimal range of IPL. Materials and methods A retrospective study design was adopted. The clinical and radiographic data of 105 implants in 65 patients were collected after 3–9 (mean 5.04) years follow-up. IPL was divided into three groups (group1, IPL<2mm; group2, 2mm≤IPL<4mm; group3, IPL≥4mm). Endo-sinus bone gain (ESBG), peri-implant marginal bone loss (MBL), bone to implant contact length (BICL), and percentage of ESBG (%ESBG) were used to evaluate non-grafting OSFE. A Kaplan-Meier analysis was performed to assess the cumulative survival rate. Multiple linear regression model was used to explore the relationship between the possible influence factors and ESBG. Analysis of variance (ANOVA) was applied to explore the correlation of IPL with ESBG, MBL, BICL, and %ESBG. Results A total of 102 implants in 62 patients fulfilled the survival criteria, giving the cumulative survival rates of 96.4% and 94.1% for implant-based analysis and patient-based analysis, respectively. The mean ESBG, MBL, and BICL at the latest follow-up were 1.95±0.88 mm, 0.58±0.68 mm, and 5.51±1.47 mm. ESBG was found to be positively correlated to IPL. A significant decreased bone formation efficiency was found when IPL was over 4 mm (P=0.02). Conclusions An optimal range of IPL within 4 mm was recommended for better long-term outcomes when applying non-grafting OSFE with simultaneous implant placement.
