Intraoral examination revealed Angle Class III molar relationship, anterior cross-bite
and moderate crowding in both arches.
(24) Buccal or lateral cross-bite
due to maxillary skeletal constriction were found to be present in approximately 30-50% of OSA patients irrespective of the severity measured.
The study group consisting of 27 patients (13 males, 14 females, and mean age 14.3+2.17 years) required RME for unilateral or bilateral cross-bite
and orthodontic treatment.
Electromyography of the temporalis and masseter muscles in children with unilateral cross-bite
. Scand J Dent Res 1970;78:425-30.
Intraoral examination showed insufficient width of an attached gingiva, gingival hyperplasia, macroglossia, cleft tongue, dental crowding, malocclusion, anterior cross-bite
and caries (31, 32, 41, 42, and 35).
Also, considered ineligible were individuals with any kind of syndrome, degenerative diseases, mental deficiencies, malformation, changes of the temporomandibular articulation, open and cross-bite
, myofunctional changes of masticatory muscles and dental implants.
The evaluated malocclusions assessed were posterior cross bite, anterior cross-bite
, anterior open bite, overbite and overjet; angle classification also being evaluated.
Previous researchers as Ricketts differentiate the main characteristics of the respiration obstruction syndrome which are presence of hypertrophied tonsils or adenoids, oral breathing, open-bite tendency, cross-bite
, other features include excessive anterior face height, incompetent lips, and V-shaped maxillary arch.19 Harvold et al.
Clinically, the patients presented a chin deviation greater than 5 mm toward the contralateral side, with a posterior cross-bite
and free of joint pain symptoms.
On smiling, many of these patients show large amounts of gingiva, the so-called "gummy smile." Either bi- lateral, or unilateral posterior cross-bite
, may be present in LFS.
Overjet was measured as the greatest distance between the incisal edges of the maxillary and mandibular primary incisors in the occlusal plane using a millimeter gauge and recorded as ideal, if a positive overjet was less than or equal to 2 mm; increased, if it was greater than 2 mm; and reversed, if there was anterior cross-bite
and edge-to-edge relationship was also assessed .
The results showed that posterior cross-bite
and adenoids-tonsils enlargement were factors significantly associated with otitis media in children.
