“…It seems that a similar decrease in free-way space can be observed when the head is positioned anteriorly (Goldstein et al, 1984). Physiotherapy aimed at re-educating an anterior head posture causes an increase in free-way space that lasts for approximately one month after termination of treatment (Ayub et al, 1984;Darling et al, 1984).…”

This review argues that (1) the habitual mandibular position is constantly variable and so cannot be considered as a craniomandibular reference point, (2) there is no unique centric relation, (3) mandibular posture greatly depends on head posture, (4) clinical evaluation of the occlusal vertical dimension is mostly empirical, and (5) neither the vertical dimension at rest nor the centric relation can be determined by means of existing instrument-based clinical methods. However, some physiological conditions exist that facilitate the recording of craniomandibular position.

“…The C7 vertebra, the fixed pivot around which this movement revolves, is the most affected by movement. 9 The dental chair was adjusted so that the movable portion of the headrest corresponded to this location in each subject.…”

“…1,[3][4][5][6][7][8][9][10][11][12][13] However, the paucity of research in this area under clinical conditions indicates that there is an inadequate understanding of the effects on mandibular position in the body and head positions patients may assume during dental procedures. In addition, there is no literature identified on the effects of head posture on mandibular position in supine patients; there is also no detailed investigation of the interrelationship between body and head postures.…”

In order to establish patient posture standards for use in the clinic, the present research considered the influence on mandibular position of the head and body posture of patients undergoing dental treatment. AbstractPurpose: The objectives of this study were to determine how changes in body and head position undergoing dental treatment affect mandibular position, and to develop a set of standards for patient posture.Methods: Mandibular position was investigated in 8 subjects with normal occlusion and not suffering any stomatognathic dysfunction. This was done by measuring the location of the tapping point on the incisal point using a Gnathohexagraph (a 3-dimensional jaw movement measurement device with 6 degrees of freedom), with the subject's head in 4 different positions while sitting, and the body and head in 16 different positions with the subject supine, and then comparing deviation from the reference position in each of these positions. Statistical analysis of data was performed using first, repeated measures of 1-way ANOVA (α =.05), second Bonferroni's multiple comparison test was undertaken in seated positions. In supine positions, repeated measures of 2-way ANOVA was performed, and followed by Bonferroni's multiple comparison test was performed. Results:The incisal point deviated significantly in the anteroposterior direction due to changes in head and body position. With the subjects seated, the incisal point tended to move backwards when the subjects were asked to lean backwards from the reference position. The incisal point tended to move forward when the subjects were asked to lean forward. With the subjects in a supine position, the incisal point was inclined backwards. The degree of backwards inclination of the incisal point tended to decline as the head position was varied from 10 degrees backwards to 20 degrees forward, regardless of the degree of backwards inclination of the body. Conclusion:Changes in body and head posture undergoing dental treatment affect incisal point deviation.

“…El desgaste dentario se relaciona con la posición espacial del plano oclusal y, basados en el concepto funcional que define la dimensión vertical oclusal [10], se puede afirmar que la influencia neuromuscular tendría un rol importante en la ubicación espacial de dicho plano. A su vez, la interrelación neurofuncional de las regiones masticatoria y cervical, que participa activamente en la función del movimiento mandibular y el posicionamiento cervical, también sería un factor relacionado [11].…”

Rev Nac Odontol. 2016;12(22) Resumen. Introducción: la proyección dorsal del plano oclusal y su inclinación en relación con la base del cráneo son indispensables para generar un análisis cefalométrico simple para rehabilitadores. Métodos: estudio descriptivo sobre telerradiografías de perfil de cráneo completo en 124 sujetos. Se determinó el lugar de proyección del plano oclusal teórico sobre la columna cervical y se midió su angulación con respecto a la línea c1 del Análisis Arquitectural y Estructural de Delaire (aaed). Se analizaron los resultados según sexo y las clases esqueletales definidas por el mismo análisis. Se propuso un análisis simple para la determinación de la posición del plano oclusal con respecto a la columna cervical, la base del cráneo y la altura facial (oclusometría). La oclusometría se validó contrastándola con el aaed completo. Resultados: de un total de 124 sujetos, 68 proyectaron el plano oclusal sobre la porción inferior del atlas y 36 sobre la articulación atlas-axis. En relación con el ángulo del plano oclusal con c1, se obtuvieron valores entre 7 y 14 grados con un promedio de 9,8º y una moda de 10º. No se observó diferencia entre clases esqueletales ni entre sexos. Con esto se propuso un análisis denominado "oclusometría". Conclusión: el plano oclusal tiende a mantener una posición estable en el espacio, lo que permite generar un estudio sobre telerradiografías, validado y útil para ayudar en la determinación de la posición del plano oclusal dentro de los límites de la dimensión vertical oclusal.Palabras clave: análisis cefalométrico, análisis arquitectural y estructural de Delaire, articulación cráneocervical, clase esqueletal, plano oclusal, telerradiografía.
