Comparison of piezosurgery and conventional rotary instruments in schneider’s membrane sinus lifting: A pilot randomized trial
2020
Background The present study aimed to evaluate and compare the postoperative effects of the piezoelectric device and conventional rotary instruments in Schneider’s membrane sinus lifting procedure. Material and Methods Twenty patients requiring bilateral maxillary bone graft augmentation in the posterior maxillary region were selected. Piezoelectric surgery was performed on one side and conventional surgery with a rotary diamond bur on the other. Postoperative pain, swelling, edema, and mouth opening were evaluated at one hour and two and seven days after the procedures. All variables were submitted to Friedman or Wilcoxon tests at a 5% significance level. Results The comparison between gro…
Piezosurgery in the excision of middle ear tumors: effects on mineralized and non mineralized tissues
2007
BACKGROUND: Piezosurgery is a new instrument able to cut bone without necrosis and non-mineralized tissue damage. The aim of this study was to test the Piezosurgery as a new and alternative method for the excision of middle-ear tumors and to analyze its effects on soft tissues. MATERIAL/METHODS: The Piezosurgery device was used to excise eight glomus tympanicum tumors and two primary B-cell lymphomas of the middle ear. The piezoelectric device uses low-frequency ultrasonic waves (24.7-29.5 kHz); the applied power can be modulated between 2.8 and 16 W and is programmed in accordance to the density of the bone. The equipment consists of two hand-pieces, two inserts, and two peristaltic pumps.…
OPTIMIZING PREIMPLANTARY OFFER TROUGH PIEZOSURGERY TECHNIQUES
2016
Introduction. In most of the cases, duet o post-extractional atrophy the bone offer is insufficent for placing implants. Piezosurgery splitting techniques represent the modern and non-invasive alternative used for ridge remodeling, sinus lift and other surgical bone preservation maneuvres. Purpose. The purpose of this study is to present new surgical techniques that radically simplify maxillary sinus interventation, avoiding membrane perforation and new splitting tecniques in advanced bone and ridge atrophy. Material and method. In this study, sinus lifting was performed using piezo-elevation of the membrane and the pressure ogenerated by the saline solution. Out of 67 patients, 20 have had…
Stability and marginal bone loss in implants placed using piezoelectric osteotomy versus conventional drilling: systematic review and meta-analysis.
2021
Background The main objective of this systematic review was to compare primary and secondary implant stability between placement with piezoelectric osteotomy and conventional drilling, comparing marginal bone losses as a secondary objective. Material and Methods An electronic search was conducted using PubMed (MEDLINE), Scopus, and Cochrane Library (Wiley) databases, besides a manual search. Results A total of 153 articles were retrieved, 39 from Pubmed, 44 from Scopus, and 70 from the Cochrane Library. After removing duplicates, 112 articles (1 from the manual search) were screened, and 9 were finally selected for qualitative and statistical analyses. Conclusions Piezoelectric surgery is a…
Efficacy of the laser at low intensity on primary burning oral syndrome: a systematic review.
2020
Background Primary burning mouth syndrome (BMS) is a chronic clinical condition of idiopathic mainly characterized by pain and a burning sensation in the oral cavity. The application of laser at low intensity therapy is a treatment option. This systematic review evaluated the efficacy of laser therapy in treating symptoms of burning mouth syndrome. Material and Methods The study was formulated according to the PRISMA and Cochrane guidelines. Seven databases were used as primary sources of research. Only randomized controlled clinical trials were included. The efficacy of the therapy was estimated comparing the values of the visual and numerical scales of pain before and after laser treatmen…
Learning curve for piezosurgery in well-trained otological surgeons
2009
Abstract Objective Piezosurgery is an ultrasound instrument (24.7-29.5 kHz) capable of cutting bone without necrosis and nonmineralized tissue damage. The aim of this work has been to determine the time required for a well-trained surgeon to perform otological surgery with the piezoelectric device. Study Design Case series with planned data collection. Sixty-three patients affected by otosclerosis and 63 by chronic otitis media were enrolled. For each disease, patients were divided into three numerically equal groups, with each group assigned to a well-trained otological surgeon. Patients underwent stapedotomy (n = 63) and intact canal wall tympanoplasty (n = 63) with the piezoelectric devi…
