Interdisciplinary Study of Orthopedic and Orthodontic Findings in Pre-school Infants

Abstract

Background and Aim: The assessment of correlations between orthopedic and orthodontic data based on interdisciplinary studies is of scientific and practical interest in the differentiation of preventive diagnostic and therapeutic fields between orthodontics and orthopedics. In the published literature there are various studies analyzing the correlations between specific Angle classes and orthopedic parameters. Results of these studies indicate a potential correlation between scoliosis and Class II malocclusion as well as between weak body posture and Class II malocclusion. The aim of the present interdisciplinary study was to examine correlations between orthodontic and orthopedic findings in preschool infants and to evaluate them with respect to preventive recommendations. Patients and Method: 59 pre-school infants (29 boys, 30 girls) aged 3.5-6.8 years (mean: 5.0 years) were enrolled in this study. A standardized orthodontic and orthopedic examination protocol was used. Results: The orthodontic examination showed Angle class distributions comparable with those in non-selected groups (Class I: 63%, Class II: 32%, Class III: 5%). The orthopedic examination revealed pathologic findings in 52% of the subjects, with statistically significant correlations between scoliosis and Class II malocclusion (p = 0.033) and between weak body posture and Class II malocclusion (p = 0.028). Conclusion: It can be concluded from the results that the orthodontic finding of Angle Class II in pre-school infants should induce prophylactic screening. The orthodontist could then not only initiate early orthodontic treatment to prevent incisor trauma in patients with extreme overjet, but could also take account of Zusammenfassung Hintergrund und Ziel: Die Bewertung von Beziehungen zwischen orthopädischen und kieferorthopädischen Befunden auf der Basis von interdisziplinären Studien ist von wissenschaftlichem und praktischem Interesse für die Differenzierung von präventiven gemeinsamen Diagnostik-und Therapiebereichen zwischen Kieferorthopädie und Orthopädie. Im bekannten Schrifttum finden sich mehrere Studien, welche Zusammenhänge zwischen bestimmten Angle-Klassen und orthopädischen Parametern evaluieren. Ergebnisse dieser Studien deuten auf eine mögliche Beziehung von Skoliosen und hypotoner Körperhaltung mit Angle-Klasse-II-Dysgnathien hin. Prospektives Ziel der vorliegenden interdisziplinären Studie war es, Beziehungen zwischen orthopädischen und kieferorthopädischen Befunden bei Vorschulkindern zu untersuchen und hinsichtlich präventiver Empfehlungen zu evaluieren. Patienten und Methode: 59 Vorschulkinder im Alter von 3,5 bis 6,8 Jahren wurden in diese Studie einbezogen. 29 Patienten waren männlich, 30 weiblich. Es erfolgten eine standardisierte klinische kieferorthopädische und orthopädische Untersuchung. Ergebnisse: Bei der kieferorthopädischen Untersuchung zeigte sich eine der Verteilung in unselektierten Gruppen entsprechende Angle-Klasse-Häufigkeit (Angle-Klasse I 63%, Angle-Klasse II 32% und Angle-Klasse III 5%). Die orthopädisc...

“…[4][5][6][8][9][10]12,15,18,32,33 The results of the present study contradict the statements made by Michelotti et al, 7 who could furnish evidence for the correlations between the jaw position and the body posture but not for lower spine sections.…”

“…4,7 As already mentioned by Korbmacher et al, 4 there are no studies on the relationship of the jaw position to the body posture regarding spine sections below the cervical spine that use substantiated study procedures. Our own previous studies also had this deficiency in the analysis of the body posture, 5,6 and this deficiency was meant to be eliminated with the rasterstereography used in the present spine examination study. Until now, an orthopedic clinical examination has been used for orthopedic diagnostics, but today we are able to use a quick, cost-effective, and valid examination method to assess the body posture.…”

“…[1][2][3][4][5][6][7] Korbmacher et al 4 summarized these findings in a systematic review. In a study series, the cephalometric assessment of lateral radiographs is used to define the relationship between the head posture and a Research Scientist, Department of Orthodontics, University of Mü nster, Mü nster, Germany.…”

“…4 . Often, a simple subjective clinical orthopedic examination is carried out [3][4][5][6] to diagnose forms of bad posture. However, some studies used noninvasive orthopedic measurement methods for the analysis of lordotic or kyphotic angles, [14][15][16][17][18] but no examination technique is described in the orthodontic literature based on light-projection methods and further computerized processing of a three-dimensional back surface profile.…”
