Assessment of Tooth Movement with Piezocision and Its Periodontal Transversal Effects in Class II Malocclusion Patients: A Clinical Study

ABSTRACT

Background: There are considerable amount of population suffering from malocclusion. An increasing number of patients are demanding orthodontic treatment for improved esthetics and a better mastication system. The present study was conducted to assess tooth movement with piezocision and its periodontal transversal effects in class II malocclusion patients. Methods: The present study was conducted in the department of Orthodontics. It comprised of 120 patients with class II malocclusion. Before canine distalization and after the alignment and leveling phases, piezocision was performed on experimental side (Group I). Tooth mobility and gingival index was assessed on both sides. Results: In group I, there was 3.56± 1. 4 months and in group II there was 5.61± 1.2 months for distalization. There was 1.54± 1.3 mm and 0.80± 1.1 mm distalization in group I and group II. The difference was significant (P< 0.05). The mobility score was 1.2 and 1.4 before and after distalization in group I and 1.3 and 1.5 before and after distalization in group II. The difference was non- significant. Gingival index score was 1.4 and 1.3 before and after distalization in group I and 1.5 and 1.6 before and after distalization in group II. The difference was non- significant (P> 0.05). Conclusion: Piezocision-assisted distalization accelerates tooth movement, decreases the anchorage loss for posterior teeth, and does not induce any maxillary transversal change. This technique does not have any adverse effects on periodontal health.
