| Abstract | ||||
| To overcome the intra and post-operative complications that might arise during the use of the conventional instruments for cutting the bony window and elevation of maxillary sinus membrane, the application of ultrasonic device (piezosurgery) has been introduced. Aim of the study: To evaluate the efficiency and safety of the piezosurgery during direct sinus lifting procedure in comparison to the conventional rotary instruments. Patients and methods: A randomized controlled clinical trial was performed, in which forty patients (17 females and 23 males) with bone height of less than 3 mm in the posterior maxilla, who required implant placement to replace the missing teeth, were selected. The sinus lift surgeries were done either by the piezosurgery or the conventional bur technique. The rate of perforation, time of the operation, healing, postoperative edema, and pain were evaluated. Six months later, implants were placed within the augmented sites. Results: A lower percentage of membrane perforation has been encountered in the piezosurgery group (5% one patient), when compared to the conventional group (15%, three patients).The pain and swelling were significantly less in the piezosurgery group but the mean time was longer in the piezosurgery group . Conclusion: The piezosurgery is an effective device that is safer in performing the lateral maxillary sinus lift surgery than the conventional rotary method, but unfortunately it takes longer operation time. | ||||
