Reduction of Excessive Overjet in Pediatric Malocclusion Using Myofunctional Therapy Accompanied by Electromyography Activity Evaluation in Orofacial Muscles

Treatment of pediatric malocclusion patients with excessive overjet with oral and facial muscle function therapy harmonious balance between size of teeth,the length of dental arch,and the facial profile.To correct diagnosis in longterm care of pediatric growth and development age,a complete clinical examination is required,including electromyography examination of orofacial muscles. Acses oral myofunctional changes in the muscles,before and after treatment.
Used E-Dentosmart electromyography diagnostic for orofacial muscle measurement.The study conducted by functional analysis and electromyography in 27 pediatric patients with overjet morethan 4mm,no history of sleep problems,pediatric patients without previous orthodontic treatment,no tonsils/adenoid hypertrophy,no malformation or systemic disease.Three groups defined for the study group:The treatment group(n=11);Untreated group(n=9) and control group(n=7),the three groups were aged 7-13 years,(mean age: 8.9±1.3= years).
There was a significant difference in the group using preorthodontic appliances,in masseter muscles before and after with pvalue<0.0001,there was also a significant difference before and after using preorthodontic exercise device with pvalue<0.001.No significant difference was found in the group not using preorthodontic exercise devices and the control group in each studied.Examination and measurement with dentosmartEMG in children,showed significant differences between treatment group,untreated group and control group.
There is a significant change in the improvement function of the craniocervico mandibular system in the normal physiology with myofunction therapy.Physiologically ideal facial and tongue muscle performance is a key factor in producing normal maxillary growth development and enabling correct tooth position.Myofunctional therapy able to restore normal resting posture of the tongue according to the pattern of oral muscles,and face nasal breathing,normal lip posture and proper swallowing pattern
