Retrieval of blade implants with piezosurgery: two clinical cases

In this work an ultrasound device was used to perform an ostectomy for the removal of blade implants in order to save as much bone tissue as possible, so that root form implants might later be inserted. Two patients underwent surgery for the removal of two blade implants (one maxillary, the other mandibular) that were no longer functional. The peri-implant ostectomy was carried out with a piezoelectric surgery device. The instrument demonstrated to be effective and precise during ostectomy, providing an extremely thin cutting line. During the course of the operation and at controls after 7 and 30 days, patients did not show any relevant complications and both still had sufficient alveolar bone to be treated with root form implants. The piezosurgery device proved to be an effective instrument in interventions requiring a significant saving of bone tissue, extreme precision in cutting, and respect of soft tissues.
