Skeletal stages of the hand and wrist as indicators of the pubertal growth spurt

Abstract

Longitudinal data on adolescent growth in height and skeletal development of the hand and wrist were collected as part of a prospective study of the growth and development of 212 randomly selected Swedish urban children. The onset, peak and end of the pubertal growth spurt were defined on the unsmoothed incremental curve of height. The skeletal development was evaluated by studying the attainment of specified stages of the ulnar sesamoid of the metacarpophalangeal joint of the first finger, the epiphyses of the middle and distal phalanges of the third finger and the distal epihysis of the radius. All growth events and skeletal stages occurred earlier in girls than in boys. At the peak of the pubertal growth spurt the skeletal development was more advanced in girls than in boys, but at the end of the spurt the girls had a less mature skeletal development than the boys. The analysis of the relationship in time between the growth events and the skeletal stages showed that these stages can be used to indicate which period of adolescent growth an individual has reached.

Comparison of stepwise vs single-step advancement with the Functional Mandibular Advancer in Class II division 1 treatment

“…Thirty-six patients (18 female, 18 male) fulfilling the following requirements were included in this study: (1) Angle Class II Division 1 malocclusion in the permanent dentition with an overjet greater than 6 mm and full-cusp Cl II molar relationship, (2) ANB greater than 48 with retrognathic mandible, (3) mild or no crowding, (4) growth period just before or at the peak of pubertal growth (evaluated by hand-wrist radiographs), 20 and (5) SN-GoGn not exceeding 388. Matched randomization 21 was used for assigning patients to study groups.…”

Efectividad de la estabilidad dentaria y oclusal con dos tipos de retenedores

“…[15][16][17][18][19][20][21][22][23][24] La recidiva se presenta en un alto porcentaje de los casos tratados con ortodoncia, con una variación individual debido a factores como el crecimiento craneofacial, el desarrollo dental, hábitos funcionales y la función muscular, lo cual exige un conocimiento preciso del desarrollo dental y esquelético de cada individuo con el propósito de planear acertadamente el tipo y tiempo de retención posortodóncica para el mismo. [25][26][27][28][29][30][31][32][33][34][35] En la práctica clínica en Colombia, y en muchos otros países alrededor del mundo, los retenedores Hawley han sido ampliamente utilizados e investigados [36][37][38][39][40][41] y desde hace algunos años ha aumentado significativamente la implementación de los retenedores tipo Essix por parte de los ortodoncistas.…”

“…[15][16][17][18][19][20][21][22][23][24] Recurrence occurs in a high percentage of cases treated with orthodontics, with individual variations due to factors such as craniofacial growth, tooth development, functional habits and muscle function; it is therefore necessary to know the individual dental and skeletal development in order to accurately plan the right type and post-orthodontic retention time for each patient. [25][26][27][28][29][30][31][32][33][34][35] In the clinical practice in Colombia and many other countries, the Hawley retainers have been widely used and researched [36][37][38][39][40][41] and for some years now the implementation of Essix retainers has been significantly increasing. [42][43][44][45][46][47][48][49] Su elección puede obedecer a la gran aceptación de los pacientes por su apariencia estética, por sus costos y por el poco tiempo requerido para su fabricación.…”

Is Herbst-Multibracket Appliance Treatment More Efficient in Adolescents than in Adults?

“…According to pretreatment skeletal maturity, analyzed by means of hand-wrist radiographs according to the method described by Hä gg and Taranger, 15 the subjects were divided into two groups. The adolescent group comprised all subjects with skeletal maturity of stages MP3-F to MP3-H, implying a prepeak to postpeak somatic maturity.…”
