A 9-year-old Chinese boy presented with an anterior crossbite, no treatment was performed at that time because the incisors have open root apices. The crossbite self-corrected after one year. This case demonstrated that an anterior crossbite may self-correct without treatment.
An anterior crossbite is the description of the upper anterior teeth having one or more occlusions at the lingual side of the lower anterior teeth. According to Lin JJ, the prevalence of anterior crossbite was 13.83% in a Taiwanese sample of 7090 elementary and junior high school students. Aged 9 to 15 years old . The presence of anterior crossbites may cause mandibular displacement, if left untreated may lead to restriction of maxillary growth, traumatic occlusion, and may lengthen the treatment time.
An anterior crossbite may cause mandibular displacement which leads to various dental problems. Early correction of the anterior crossbite may facilitate the eruption of canines and premolars into Class I , eliminates traumatic occlusion to the incisors [4, 5] (which may lead to dehiscence and gingival recession), providing a normal environment for growth of the maxilla , and can often improve the self esteem of the child -. Therefore early correction of the crossbite is indicated. In this case, correction of the anterior crossbite was postponed in view of the open apex. The crossbite subsequently self-corrected. It should be noted that this is not common. It is usually necessary to correct the crossbite by orthodontic means as an interceptive measure and this case was an exception to this general condition. It is possible that the tongue may have proclined the incisor, as there was space to allow this to occur.
Written informed consent was obtained from the patient for publication of this case report and accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal.
