“…Differences in the developmental stages of the subjects at the time of treatment could have affected the findings. Although developmental age is a more accurate guide for predicting the adolescent growth spurt, a recent study 14 suggests that in the absence of hand-wrist radiographs, chronological age might be the next developmental index of choice. Furthermore, it has been shown that chronological age may be an adequate indicator of development age.…”

Objective: To compare the short-term skeletal and dental effects of two-phase orthodontic treatment including either a Twin-block or an XBow appliance. Materials and Methods: This was a retrospective clinical trial of 50 consecutive Class II cases treated in a private practice with either a Twin-block (25) or XBow (25) appliance followed by full fixed orthodontic treatment. To factor out growth, an untreated Class II control group (25) was considered.Results: A MANOVA of treatment/observation changes followed by univariate pairwise comparisons showed that the maxilla moved forward less in the treatment groups than in the control group. As for mandibular changes, the corpus length increase was larger in the Twin-block group by 3.9 mm. Dentally, mesial movement of mandibular molars was greater in both treatment groups. Although no distalization of maxillary molars was found in either treatment group, restriction of mesial movement of these teeth was seen in both treatment groups. Both treatment groups demonstrated increased mandibular incisor proclination with larger increases for the XBow group by 3.3u. The Wits value was decreased by 1.6 mm more in the Twin-block group. No sexrelated differences were observed. Conclusions: Class II correction using an XBow or Twin-block followed by fixed appliances occurs through a relatively similar combination of dental and skeletal effects. An increase in mandibular incisor inclination for the XBow group and an increased corpus length for the Twin-block group were notable exceptions. No overall treatment length differences were seen.

“…Finally, events in the hand and wrist are indicators of the peak and the end of the pubertal growth spurt, but these events do not signal the onset of the pubertal growth spurt. 15 The cervical vertebrae maturation (CVM) method was introduced by Lamparski 16 for use in growth assessment, allowing skeletal age evaluation and eliminating the need for additional radiographic exposure since the vertebrae are already recorded in the lateral cephalogram taken as a pretreatment record. 1,5,14,17,18 However, the reproducibility of the CVM method has been questioned.…”

Objective: To identify and review the literature regarding the reliability of cervical vertebrae maturation (CVM) staging to predict the pubertal spurt. Materials and Methods: The selection criteria included cross-sectional and longitudinal descriptive studies in humans that evaluated qualitatively or quantitatively the accuracy and reproducibility of the CVM method on lateral cephalometric radiographs, as well as the correlation with a standard method established by hand-wrist radiographs. Results: The searches retrieved 343 unique citations. Twenty-three studies met the inclusion criteria. Six articles had moderate to high scores, while 17 of 23 had low scores. Analysis also showed a moderate to high statistically significant correlation between CVM and hand-wrist maturation methods. There was a moderate to high reproducibility of the CVM method, and only one specific study investigated the accuracy of the CVM index in detecting peak pubertal growth. Conclusions: This systematic review has shown that the studies on CVM method for radiographic assessment of skeletal maturation stages suffer from serious methodological failures. Betterdesigned studies with adequate accuracy, reproducibility, and correlation analysis, including studies with appropriate sensitivity-specificity analysis, should be performed. (Angle Orthod.

“…Além disso, existem diversos autores que defendem que este método deve ser utilizado com muita precaução 18,40 ou mesmo que não deve ser utilizado para identificar os picos de crescimento da mandíbula uma vez que apesar de se conseguirem visualizar as diferenças na forma e tamanho das vértebras, não se conseguiram associar aos estádios de maturação correspondentes ao maior ou menor crescimento mandibular, em parte devido à grande subjetividade e ao seu carácter qualitativo em vez de quantitativo.
