Effects of Bionator Devices on Orofacial Muscle Strength in the Treatment of Class II Malocclusion in Developmental Phase: Systematic Review

Abstract

Background: Class II malocclusion is a common condition. The most common clinical presentation is a mandibular deficiency. Treatment with functional devices is an option that can be used for the treatment of malocclusion. In an era of evolving treatments, Bionator is still widely used in clinical practice.
 Objective: The purpose of this systematic review was to analyze the effectiveness of the treatment of class II malocclusion with the Bionator device in the growth and development phase. Methods: Data collection was carried out by searching literature on article search sites, namely Pubmed, Cochrane, Wiley, Google Scholar and Science Direct which were published from 2011 to 2021. The search was carried out from March to April 2021. Data search was carried out systematically using the bionator keyword. malocclusion class II, orofacial muscles, growth and development.
 Results: After eliminating published articles, the title and abstract of each article in the analysis amounted to 132 articles, 106 articles were excluded. The full text articles from the exclusion results were re-analyzed and 16 articles were excluded. The text of the article is complete and meets the eligibility of as many as 10 articles.
 Conclusion: From all the studies reviewed, the Bionator device can improve class II malocclusion in children.

Evaluation of Electromyography and Muscle Contraction in the Use of Myofunctional Appliances: A Systematic Review

“…The use of my functional appliances aims to modify growth by utilizing, removing or guiding muscle function, jaw growth, tooth eruption, to correct malocclusion and treat jaw discrepancies.23,24 Myofunctional appliances can change the function of the oral and facial muscles and to eliminate oral habits, such as prolonged thumb sucking and nail biting, tongue thrusting, mouth open at rest, poor mastication, and poor tongue and mouth posture, orthodontists also use my functional appliances as an adjunct to the treatment of temporomandibular joint disorders (TMD). 22,25 My functional appliances are classified into two, namely removable devices and fixed devices. There are two types of removable devices, namely active removable devices, which are devices used to move the teeth and passive removable appliances, which are devices used to move teeth.…”
