Short vs standard implants associated with sinus floor elevation: a randomized controlled trial

Objective: the present equivalence two-arm parallel randomized controlled trial aimed to compare survival and marginal bone loss (MBL) of short implants (≤6 mm) standard (≥8.5 associated with sinus floor elevation (SFE). Methods: adult patients partial edentulism occlusal stability in area intermediate height were selected this double-blind (patient outcome assessment). Patients randomly allocated into two groups: length SFE (control) or (test). Clinical radiographic assessments made at time implant placement, 6 months, annually thereafter up 2 years after loading. The inter-examiner agreement was analyzed using intraclass correlation coefficient (ICC). One-way ANOVA, Kaplan-Meier, Log-rank tests used (primary outcome) MBL (secondary (P<0.05). Results: eight six placed (mean age 47 ±12.5 years). rates 87.5% for (one 5 mm failed 7 months) 100% no statistically significant difference between groups (P=0.4). mean 1 year 0.30 ±0.62 0.21 ±0.36 (P=0.123). set 0.831. Conclusion: similar clinical service. Trial registration: Registered on 27-03-2018 ClinicalTrials.gov (NCT03479333).
