A New Syndesmotomy Technique for Tooth Extractions: Preserving the Integrity of the Alveolar Bone
A New Syndesmotomy Technique for Tooth Extractions: Preserving the Integrity of the Alveolar Bone
In both surgical and nor surgical tooth extractions, the first phase is done by syndesmotomy. This procedure allows to interrupt the fibers of the periodontal ligament. Traditionally, syndesmotomy is done by manual instruments. Usually, the manual approach leads to the loss of the vestibular cortical plate due to the size of those instruments.
The piezoelectric surgery device provides an alternative to manual instruments. Its advantages are: selectivity for hard tissues; better cut control; protection of soft tissue, vessels and nerves; post-op pain and discomfort reduction.
The aim of this study is to evaluate a piezosurgery driven syndesmotomy technique during tooth extraction.
Piezoelectric bone surgery is a recent and innovative technology, permitting a selective cut of mineralized tissue while sparing soft tissue. Similar to a dental scaler, a high frequency vibration, in the range of 25-35 kHz, is transmitted to a metallic tip. The handpiece of the instrument is equipped with a sterile irrigation system and light-emitting diode (LED) light, which improves visibility and overall safety. Piezoelectric surgery is particularly useful when performing delicate bone procedures such as periodontal or endodontic surgery. It is also indicated when performing more invasive bone surgery such as maxillectomy, mandibulectomy, and condylectomy, where preservation of neurovascular structures is important. Piezoelectric surgery is still employed in tooth extraction of third lower molars. In literature, there are low evidence of the use of piezoelectric surgery for single-rooted tooth extraction.
