Piezosurgery – A novel tool in modern dentistry

Dentistry has undergone significant improvement with a lot of changing concepts involving novel surgical tools over the past two decades. Piezoelectric surgery, also popularly called as piezosurgery (PS), is a rapidly evolving technique of bone surgery which is gaining importance because of its ability to place osteotomy cuts with absolute precision and confidence, especially near the vital structures. Piezosurgical device functions with an ultrasonic frequency (25–29 KHz) resulting in microvibrations in the range of 60–200 µm/s enabling bone cutting that is secured and accurate preserving the underlying neurovascular elements along with improved visibility through bloodless surgical site and thorough debridement using internal irrigation system. Till date, PS has seen wide applications in various disciplines of medicine. In the field of dentistry, PS has emerged as a promising technical modality in bone graft harvesting, alveolar ridge expansion, sinus lift procedures, osteogenic distraction, and endodontic and periodontal surgeries. The present review addresses the efficiency of PS comparing it with the traditional dental surgical equipment. The advantages, limitations, and biological effects of PS as well its various applications in dentistry have also been discussed.

EVALUATION OF MINERALIZED PLASMATIC MATRIX DURING SINUS LIFT WITH THE SIMULTANEOUS PLACEMENT OF DENTAL IMPLANTS

Objectives:Mineralized plasmatic matrix is reported to improve the quality of the bone/fibrin mixture, creating a stable and easy to handle homogeneous material. However, few studies evaluate the use of the mineralized plasmatic matrix during sinus lift with the simultaneous placement of dental implants. Purpose: This study evaluated the efficiency or not of MPM compared to the xenograft bone grafting in the maxillary sinus lift. Patients and methods:This study was conducted randomly on patients selected for treatment with a total of sixteen lateral windows sinus lift with simultaneous implant placement. Their ages ranged between 20 and 60 years old. Participating patients were divided into two groups equally and randomly The control group: eightsinus floor elevation was performed using simultaneous implant placement. As a grafting material, Xenograft was used. The study group: eight Sinus floor elevation was achieved with simultaneous implant placement. Xenograft has been used in the form of MPM as a grafting material. CBCT taken before and after sinus augmentation to measure bone volume and height after 1 week of baseline (T0), after 6 months (T1), and after 12 months of baseline (T0) (T2). The Osstell(PT) was used for assessment implant stability at implant insertion (PT0) as well as for loading visit (PT1). Result:A significant difference was observed between the two groups in bone volume (p=0.049). No significant difference was observed between the two groups (p=0.129) in height of graft. Conclusion:MPM eliminated the need for barrier membranes when a guided bone regeneration procedure is considered.The useofMPM as a grafting bone offered greater graft stability and handling.
