- Abstract
To compare the effects of maxillary sinus elevation with simultaneous implant placement using hydrodynamic piezoelectric internal sinus elevation(HPISE) with endoscopy and lateral window osteotomy (LWO) .16 consecutive patients withing residual crestal height of 2 to 5 mm were randomly divided into two groups based on the technique. 8 patients with 15 implants were allocated to the LWO group, the other 8 patients with 14 implants were allocated to the HPISE group. Clinical examination, radiographic assessment, resonance frequency analysis (RFA), surgical duration and patients' evaluation of postoperative swelling and pain were assessed between two groups at different time points. 2 membrane perforations in the LWO group and 1 membrane perforation in the HPISE group were noted. After an average 9-month' healing, mean bone height gain in the LWO group was 5.37±1.16 mm while that of the HPISE group was 5.27±1.07mm. Osstell values increased over time and no differences of the mean ISQ changes between groups were found at any time points. No significant difference was recorded concerning the duration of the surgery. However, the patients showed a preference for the HPISE technique on behalf of the postoperative swelling and pain (P <0.05=. After mean 3- year post-loading, no implants and prostheses failed in both group. HPISE technique could be an alternative method to traditional sinus augmentation using LWO technique for reducing postoperative swelling and pain. Frequent membrane perforations in HPISE could be avoided when endoscopy was used.
