Abstract

Lip sucking and lip biting in the primary-dentition period can cause the upper incisors to tip labially and the lower incisors to collapse lingually with the lower lip wedged between the upper and lower anterior teeth. The resulting lip incompetence further aggravates maxillary protrusion. Thus, there is a causal relationship between lip sucking/lip biting and maxillary protrusion. Orofacial myologists provide lip training to activate the flaccid upper lip and raise the child's awareness to·help stop the sucking or biting of the lower lip, sometimes using an oral screen. Two primary-dentition cases with lip sucking and lip biting were treated with a functional appliance (F.A.), resulting in the elimination of the habits in 5 to 6 months along with the improvement of the overjet, overbite and facial profile. The authors prioritize myofunctional therapy (MFT) when treating open bite cases with tongue thrust in the primary dentition. However, the treatment of maxillary protrusion due to lip sucking and lip biting is approached differently with priority given to morphological improvement to create an oral environment that makes lip sucking and lip biting difficult, which is complimented with lip exercises and habituation. This combined approach was found to be effective in breaking the lip-sucking and lip-biting habits. Full article

Cephalometric Evaluation in Children Presenting Adapted Swallowing During Mixed Dentition

by Milene Maria Bertolini, Sérgio Vilhegas, Denise Yvonne Janovitz Norato and Jorge Rizzato Paschoal

Int. J. Orofac. Myol. Myofunct. Ther. 2003, 29(1), 29-41; https://doi.org/10.52010/ijom.2003.29.1.3 - 1 Nov 2003

Abstract

The tongue trust and anterior projection through the dental arcades during swallowing is known as Adapted Swallowing (AS) and is a common finding during mixed dentition. The authors studied the morphologic dentofacial characteristics through cephalometric measures in 38 girls and 35 boys, aged seven to nine years, presenting AS, as determined by the speech therapist evaluation. Cephalometric evaluation was obtained by Radiocef 2.0 software. The measurements studied were the mandibular and maxillary relations to the cranial base, the nasolabial angle, and the upper airway patency, as proposed by McNamara Jr (1984), and the convexity and facial axis angles and maxillary height from Ricketts (1960; 1981). Results, analyzed in relation to sex and racial group, showed an association of Class II facial convexity with the African Brazilian children with dark black skin. This classification does not reflect an abnormality as all African Brazilians studied were classified as class II, due to the fact that the standard measurements are based in the white American population. These findings point to the need of specific racial normative standard for evaluating orofacial and dental structures. Full article

Oral Structures and Sleep Disorders: A Literature Review

by Licia Coceani

Int. J. Orofac. Myol. Myofunct. Ther. 2003, 29(1), 15-28; https://doi.org/10.52010/ijom.2003.29.1.2 - 1 Nov 2003

Abstract

In recent years, a wealth of studies revealed the many physiological and histological changes the oropharyngeal muscles go through as a result of sleep disorders, in particular, as a result of Obstructive Sleep Apnea (OSA). This article presents a literature review of the most recent findings regarding sleep disorders and their effect on oropharyngeal structures. The article includes classifications and definitions of various sleep disorders; explains the negative implications of sleep disorders in children, as well as in adults; reviews the viable options to treat sleep disorders; suggests steps in which the orofacial myologists could be instrumental in identifying and referring patients with possible sleep disorders; and suggests further studies on the subject conducted by orofacial myologists.

Effects of Orofacial Myofunctional Therapy on Speech Intelligibility in Individuals with Persistent Articulatory Impairments

by Jayanti Ray

Int. J. Orofac. Myol. Myofunct. Ther. 2003, 29(1), 5-14; https://doi.org/10.52010/ijom.2003.29.1.1 - 1 Nov 2003

Abstract

This study examined the effects of orofacial myofunctional therapy (OMT) on speech intelligibility in adults with persistent articulation impairments. Six adults in the age range of 18–23 years were selected to receive orofacial myofunctional therapy for a period of six weeks. The results showed that five out of six clients made significant progress in oral postures and speech sound production across all three speech production tasks: single words, sentences, and spontaneous speech. Speech intelligibility increased significantly in all clients except the one diagnosed with developmental apraxia of speech. Orofacial myofunctional therapists, speechlanguage pathologists, and other professionals need to rule out underlying orofacial myofunctional variables when targeting speech sounds for intervention. Speech production tasks may be considered as important measures to understand the efficacy of OMT in clinical settings. Full article
