Main: Histological, histomorphometric and radiological comparison between autograft and xenograft (Osteobiol Mp3®) on maxillary sinus lateral osteotomy. Materials and methods: Split mouth randomized controlled trial,12 patients sample, 6 months of follow-up. Pre-CT scan was performed to assess the initial bone height, plan simultaneous bilateral sinus lift surgery, and intraoral autograft harvesting. After six months, a CT was performed to reassess the bone volume, plan the implants placement and collect a bone sample. Results: Histologically wera observed, several stages of remodeling, without inflammation/infection. Histologically, the mean percentage of bone/connective tissue was 57.3%/42.7% vs. 56.0%/44.0% (auto vs xeno, p = 0.380). At patient's scale analysis, there were no significant differences in the performance of the material (p = 0.376). A signifcant effect of the patient (p AID - 857735
