Abstract Aim To evaluate implant stability and histological outcomes after osteotome sinus floor elevation ( OSFE ) procedure, to compare new bone formation osseointegration with without grafting. Material methods simultaneous placement was conducted bilaterally on 6 Labrador dogs. Twenty‐four implants were placed. The right side (Group 1) grafted biphasic calcium phosphate BCP ), whereas the left 2) any grafting materials. animals euthanized 8 24 weeks surgery for histomorphometric assessment. Bone‐to‐implant contact BIC %), alveolar height ABH density BD material GMD measured. ISQ assessed using resonance frequency analysis RFA at 1, 2, 4, 8, 12, surgery. Results Endo‐sinus direct surface observed in two groups both time points. showed no difference between % Group 2 (40.05%, 35.90%) higher than those 1 (23.30%,25.59%) weeks. Significant shrinkage of seen 1. 24.35%, while it dropped 19.90% changing pattern similar. Conclusions Spontaneous better bone‐to‐implant found application during procedure advantages results.
