Aim The purpose of this study was to evaluate alveolar height at the antral floor following dental implant placement after an indirect sinus lift using osseodensification (OD) with the HaeNaem bur system. Materials and methods A total of 12 patients seeking implant rehabilitation in the maxillary posterior region were selected for the study. Preoperative cone beam CT (CBCT) was performed to measure the residual crestal bone height (RCBH).

Long implants have always been considered more desirable in this respect but in patients with advanced alveolar bone resorption, their placement is problematic due to the anatomic boundaries. This holds more true in relation to the posterior maxilla wherein the residual crestal bone height is usually compromised due to pneumatizing sinus floor.

LLW stream generated from the ion exchange treatment of ILW contained high concentrations of carbonates, tributyl phosphate (TBP) degraded products and problematic radio nuclides like (106)Ru and (99)Tc. Presence of TBP degraded products was interfering with the co-precipitation process.
