“…The present study aimed to determine the effect of an acute change in OVD on intraoral pressure and the perioral musculature during water swallowing. It has been suggested that lack of adaptation of the soft tissues to a new incisor position may play a role in the relapse of AOB following orthodontic treatment in some individuals (8)(9)(10)(11)(12)(13)(14)(15). Therefore, this research focused on the two sites most likely to affect the upper incisor position, the labial and just palatal to the surface of the upper central incisors.…”

“…A number of authors have noted an association between the development of anterior open bite (AOB) and a tongue thrust swallow pattern. Resting forces of the tongue exerted on the anterior dentition have been considered as a factor in tooth movement resulting in the development of an AOB (8)(9)(10)(11)(12)(13)(14)(15). There is a lack of evi-dence clarifying whether this swallow pattern is a causative factor in AOB or an adaptation to ensure anterior oral seal, which self-corrects once the AOB is closed orthodontically (8)(9)(10).…”

Abnormal swallow patterns have been associated with specific dentofacial traits, such as an anterior open bite, but the cause-effect relationship between swallowing and malocclusion remains highly controversial. The aim of this research was to determine the effects of acute change in occlusal vertical dimension (OVD) on intraoral pressure swallow patterns and perioral electromyographic activity (EMG) during swallowing. Ten volunteers (five female, five male; 27-32 years) repeated standardised swallowing tasks as the OVD was progressively increased using mandibular trays of different heights. Standardised swallowing tasks were performed repetitively with each tray in place. Individual swallowing waveforms were quantitatively and qualitatively analysed. Peak pressure, swallow duration, time to peak pressure and lip EMG peak activity were assessed for each swallow. Data were analysed using mixed-model analysis. As OVD increased, lip peak pressure during swallowing increased almost threefold (+2·1 kPa; P ≤ 0·001), whereas swallow duration increased by 12·7 per cent (+160 ms; P = 0·01) at lip level and by 26·4 per cent (+270 ms; P < 0·001) at tongue level. Perioral muscle activity during swallows increased by 43·7 per cent (P ≤ 0·01) up to the OVD where resting lip seal was not attainable. Swallowing waveforms varied markedly between individuals, but interindividual waveforms were only minimally affected. The adaptive response and the waveform similarities associated with OVD variation supports the existence of a central control mechanism for swallowing, which may be modified by peripheral inputs.

“…A tongue crib or tongue spurs can be used during orthodontic treatment to modify tongue posture, maintain stability of treated open bite, and prevent relapse, by establishing a new engram. 9 , 10 , 11 However, many orthodontists underestimate the importance of upper airway obstruction in oral habits. Anomalies of the nasal septum, turbinates, adenoids, or tonsils and chronic sinusitis can markedly alter respiratory dynamics, compromising dental arch development.…”

A 27-year-old man presented an anterior open bite relapse. He had low tongue posture positioned anteriorly at rest and during swallowing and reported chronic difficulty in nose breathing. Head cone-beam computed tomography revealed nasal septum deviation, right turbinate hypertrophy, and left maxillary sinus congestion, which were thought to contribute to the breathing problem, encourage the improper tongue posture, and thereby cause the relapse. Multidisciplinary treatment involving an otorhinolaryngologist, an orthodontist, and a periodontist resolved the upper airway obstruction and corrected the malocclusion. The follow-up examination after 3 years 5 months demonstrated stable results.
