Comparative Clinical Study of Using Piezoelectric Ultrasound Surgery Versus Conventional Technique in Sinus Lifting Procedure with Simultaneous Implant Insertion

Introduction: Several methods have developed and are currently used for sinuslifting and augmentation. Aim: this study aimed to make a comparison betweenpiezoelectric ultrasound surgery and conventional technique in sinus lifting procedurewith simultaneous implant insertion. Materials and Methods: This case series consistedof twenty-four sinus elevations using the buccal lateral approach technique, the patientshad defective upper posterior teeth for a long time with pneumatization of the sinus,they had bone height 5-7 mm which was insufficient for routine implant placement.Result: The results were evaluated by one-way analysis of variance. P values of lessthan 0.05 were considered to indicate a significant difference, bone density and implantstability are measure with CT for 6 months. Conclusion: While implant survival andbone gained are better with the ultrasound technique, perforations of the maxillary sinusmembrane are more frequent in direct sinus lifts performed with the rotary technique(7%) than with ultrasound (1.7%).
