Current Surgical Solutions for Maxillary Sinus Augmentation

Jun 4, 2014

Typically, surgeons use surgical burs during conventional oral and maxillofacial or implant surgeries to cut or split the bone. No matter how accurate a surgeon can be, there is always the risk of damaging the surrounding soft tissue and opposing anatomical landmarks such as inferior alveolar nerve or Schneiderian membrane in maxillary sinuses. Piezosurgery is one of the newest technologies for cutting bone. The Piezosurgery unit generates ultrasonic micro-vibrations, which is only effective on bone but it has no effect on the surrounding soft tissues such as nerves, periosteum or the Schneiderian membrane of the maxillary sinus. Because of its highly selective and accurate nature, it is an ideal technology for implant site preparation, sinus lift and ridge split surgeries. In addition, piezosurgery reduces the healing time of the patient to a great extent.
