Background Biomaterials are commonly used to augment the maxillary sinus floor prior to or in conjunction with dental implant installation. Recently, porous titanium granules ( PTG s) have been used in oral implant surgery to stabilize implants and function as an osteoconductive matrix. Purpose To evaluate if PTGs can be safely used in a larger population of patients, treated by different surgeons, when sinus floor augmentation was required in conjunction with implant installation. The primary endpoint was 12‐month survival rate of the dental implants. Biopsies for histology were taken from the augmented area. Materials and Methods At five centers, 40 subjects with uni or bilateral posterior edentulism and atrophy of the posterior maxilla (3–6 mm) were enrolled. In a single‐stage procedure, PTG and one to three dental implants were installed in each quadrant. In total, 70 implants were included in the study. Results One immobile implant was removed. The mean marginal bone loss was 0.5 mm and 0.8 mm, on the mesial and distal side, respectively. Histologically, all biopsies demonstrated bone ingrowth. Conclusions The results suggest that PTG can be safely and effectively used as augmentation material in the sinus floor when used with dental implants in a one‐stage procedure.
