Evaluating clear aligners and conventional braces in treating TMJ and Speech Impediment

Started May 2, 2022

Abstract or project description

Orthodontics is the study of treating misaligned occlusion, malpositioned teeth & jaws, and facial growth modification. A variety of orthodontic treatments can prevent these misaligned bite patterns and fix malpositioned teeth & jaws through straightening/moving teeth with the assistance of orthodontic materials. A concept many people do not commonly relate to orthodontics is speech impediment and TMJ (Temporomandibular Joint) issues. Current research shows both braces and clear aligners are very strategic materials that move teeth efficiently, but very few research articles contain information that specifies a better choice for treating speech impediment/TMJ. A systematic review was conducted to evaluate if adult patients with speech impediment and TMJ issues are more likely to have a better outcome in the treatment of these symptoms with conventional (e.g. traditional braces) or new orthodontic treatments (e.g. clear aligners). Results show clear aligners work quickly and are less painful for adults, however conventional braces are proven to be highly effective in treating moderate to severe cases of malocclusions, while clear aligners are best for simple malocclusions. Although this is a popular result, some articles continue to state that the comparison is inconclusive and that both materials effectively treat all cases of malocclusions. Be that as it may, it is significant that issues like speech impediment and temporomendibular (TMJ) isues are fixed quickly and efficiently to relieve symptoms before conditions worsen. Other external factors like comfortability, pricing, compliance, treatment duration, should be considered when making a decision on one of these options. Clear aligners and conventional braces have its pros and cons, but one thing is certain, they are both well-known treatment options and a clinical trial is yet to determine the efficiency.
