Comparison between Conventional & Piezocision Assisted Orthodontics in Relieving Anterior Crowding: A Systematic Review and Meta-Analysis
Introduction: Prolonged orthodontic treatment is a great concern and poses risks to the teeth and surrounding tissues. Orthodontic tooth movement can be accelerated by introducing regional insult, which increases the bone turnover and hence the reorganizing activity. Evidence suggests piezocision to be minimally invasive and clinically effective. The aim of the present study was to compare the effectiveness of conventional and piezocision assisted orthodontics in relieving anterior crowding.
Materials and Methods: Electronic and manual searches were conducted in multiple databases including PubMed, Dental and Oral Sciences, Cochrane and Cinahl Plus until April 2019. Initial search yielded 3013 studies with 8 articles meeting the inclusion criteria. The primary outcome assessed was time required for the alleviation of crowding. The secondary outcomes evaluated were pain, root resorption and periodontal health. Studies having homogenous data were included in the meta-analysis using the RevMan software.
Results: Out of the eight articles that fit the inclusion criteria, six were RCTs and two were NRCTs. Significant differences were found in alignment time and pain experienced by the patient between conventional and piezocision assisted orthodontic treatment. However, gingival health and root resorption showed non- significant differences. The forest plot of meta-analysis depicted significant difference (p = 0.03) in the alignment time between the treatment modalities. Difference in pain levels were found to be non- significant (p = 0.78).
Conclusions: Piezocision is effective in accelerating orthodontic tooth movement and alleviating crowding when compared to conventional therapy. No negative effects on periodontal health, root resorption and pain perception were found in the long term.
