Abstract

PurposesThe objectives were to assess the skeletal age of patients with skeletal open bite and to estimate and compare the mean chronological age related to CS3 and CS4 (cervical stage, CS) and the duration of the pubertal growth spurt (PGS).MethodsOrthodontic records of 145 patients were analyzed in this retrospective cross-sectional study. The study group comprised 104 patients with skeletal open bite (angle between cranial base plane line [NS] and mandible base plane line [ML] > 39° according to Steiner), whereas the control group comprised 41 patients with normal anteroposterior and vertical measurements. Skeletal age was assessed using the 6‑stage CVM (cervical vertebral maturation) method according to Baccetti. Quantitative variables were characterized by means of the arithmetic mean and standard deviation. The PGS duration was calculated as the difference between the means of the chronological ages related to CS3 and CS4.ResultsIn the study group, the arithmetic means related to CS3 and CS4 were 11.12 and 13.54 years, respectively; the duration of the PGS was 2.42 years. In the control group, the arithmetic means related to CS3 and CS4 were 10.71 and 11.82 years, respectively; the duration of the PGS was 1.11 years.ConclusionsIn patients with skeletal open bite, the duration of PGS is longer but it occurs at a similar chronological age compared to patients with normal anteroposterior and vertical measurements. The PGS in males begins later than in females. Knowledge on the longer growth spurt in patients with skeletal open bite compared to patients with normal anteroposterior and vertical relationships can be useful in the selection of an appropriate therapeutic method and also provides information about the possibility of a longer and thus more effective orthopedic approach directed at positive change in the vertical growth pattern during intense bone remodeling.

Highlights

  • In orthodontic treatment of growing patients, successful outcome depends on the proper selection of the treatment method and outcome of functional treatment is related to the optimal use of the craniofacial growth potential, i.e., the timing for orthopedic treatment is critical [1,2,3]

  • Common inclusion criteria for the study and control groups included CS3 or CS4 stage according to the Baccetti cervical vertebral maturation (CVM) method which is comprised of six maturation stages, age (7–18 years), good quality medical records, no previous orthodontic treatment, and no genetic syndromes

  • The minimum age in the female group with normal anteroposterior and vertical measurements was 1 year and 1 month lower compared to males (9 and 10.08 years, respectively)

Summary

Introduction

In orthodontic treatment of growing patients, successful outcome depends on the proper selection of the treatment method and outcome of functional treatment is related to the optimal use of the craniofacial growth potential, i.e., the timing for orthopedic treatment is critical [1,2,3]. The cervical vertebral maturation (CVM) method is used in orthodontics to determine the skeletal age. It is based on the assessment of cervical vertebral maturation using lateral cephalometric radiographs. This method was originally described by Lamparski in his master’s degree thesis in 1972 [9]. Cephalometric radiographs are routinely used in the diagnosis of patients with malocclusion [12, 13]
