The Effect of Piezocision on the Rate of Tooth Movement during Distalization of Maxillary Molars: A Randomized Clinical Trial

Abstract

The treatment of Class II malocclusions has always been a subject of great interest for orthodontists. The use of so-called “distalization" mechanics to correct Class II malocclusions is a common treatment modality. Many devices have been developed and used to distalize the maxillary molars and show positive clinical results. Some appliances need patient compliance but alternative methods termed noncompliance appliances have been presented to overcome the problem of compliance and correct Class II malocclusion efficiently. With the introduction of skeletal anchorage the problem of loss of anterior anchorage with distalization was overcome. Shortening the duration of orthodontic treatment including the maxillary molar distalization phase has been a recurring request by many adult patients. Surgical and non-surgical tooth movement acceleration techniques have been investigated by many researchers in order to overcome prolonged orthodontic treatment time. Piezocision is a minimally invasive surgical technique used for acceleration of orthodontic tooth movement in addition to improvement of patient’s periodontal biotype.
