title: Piezosurgery-assisted, flapless split crest surgery for implant site preparation.
abstract: BACKGROUND
  Bucco-lingual resorption of the alveolar ridge can, at times, be predictably corrected at the time of implant placement. Among the different options available to achieve this are a group of surgical techniques described as split crest or split ridge procedures. Most of these procedures require the use of a mallet and some type of chisels and/or osteotomes; they are very technique-sensitive and can be uncomfortable for patients. Recently, alternative tools to split the crest have been presented, and these include the newer bone expanders and the piezoelectric scalpel. A flapless approach to implant dentistry has become popular with the aim to alleviate post treatment side effects, accelerate healing and avoid bone resorption caused by flap elevation.
  
  
  METHODS
  We present a technique combining the use of a piezoelectric scalpel and a tapered bone expander in a flapless fashion as a novel way to perform split crest procedures with an aim to optimize outcomes and acceptability by patients.
  
  
  RESULTS
  All implants were successfully placed and the resorbed ridge expanded in the same setting. Findings were confirmed by postoperative cone beam cat scan (CBCT) evaluation.
  
  
  CONCLUSIONS
  This new technique is a predictable approach for split crest procedures and has high acceptability by patients and is technically simple for surgeons.
