“…[46] This outcome however contradicts previous studies. [33,35] In both groups, patients with a worse OQLQ at baseline were likely to end up with an improved OQLQ, but still worse than others who started with a relatively better OQLQ. Brunault et al reported that significant depression before surgery is associated with poorer QoL scores.…”

Aim: To investigate the relationship between post orthognathic surgery changes in soft and hard tissue cephalometric variables in Class II and Class III patients and quality of life (QoL) measured using a condition-specific QoL questionnaire and to determine cephalometric predictors of the overall OQLQ after surgery. Methods: The sample included 50 orthodontic patients, 28 Class II and 22 Class III skeletal relationships whose treatment included orthognathic surgery. Correlations between cephalometric changes and Orthognathic Quality of Life Questionnaire (OQLQ) were tested by Pearson’s correlation. Multiple linear regression was used to determine cephalometric predictors of the overall OQLQ after surgery. Results: In Class II patients, OQLQ before surgery and changes in SNA were significant predictors for OQLQ after surgery. For Class III patients, OQLQ after surgery was significantly correlated with the change in mandibular plane angle and lower face height (r = 0.6 and r = 0.5 respectively). The decrease in facial angle was negatively correlated with OQLQ (r = -0.4). Mandibular plane angle, mandibular length, and OQLQ before surgery were significant predictors for OQLQ after surgery. Conclusion: QoL improved for Class II and III after orthognathic surgery. Changes in certain cephalometric measurements seem to predict quality of life after orthognathic surgery.

“…[31,32] While cephalometric values can still be used to predict treatment outcomes, relying solely on this approach may result in inadequate corrections and subsequent dissatisfaction. [33,34] Therefore, treatment planning should consider the impact of both soft and hard tissue changes on patients' QoL.…”

Background: This study aimed to investigate changes in the facial soft and hard tissues changes among the average-angle skeletal class Ⅰ Chinese adult females receiving extraction orthodontic treatment, as well as the correlations between them. Methods: The 3dMD® stereo photography technology was used to explore facial soft tissue changes, and lateral cephalograms and cone beam computed tomography (CBCT) to explore hard tissue changes. A total of 23 adult females were recruited, among which 11 patients were with teeth extraction, 12 patients without teeth extraction treatment. Results: Among the 3D distance measurements, decreased soft tissue changes of 1/3 Face height, Stomatological height, Chin height and Lip width were observed (p<0.005), in which Lip width was found to have a moderate correlation with the decreased hard tissue change of upper inter-first molar width (d5) (ra=0.619, p<0.005). Among the 3D angle measurements, decreased soft tissue changes of Chin-lips angle and Lip angle, were found, in which Lip angle was found to have a moderate correlation with the decreased hard tissue changes of ∠U1-SN (ra=0.659, p<0.005). While the Soft tissue angle and Nasolabial angle increased post-orthodontics (p<0.005). In addition, moderate negative correlations between Nasolabial angle and hard tissue changes of ∠U1-SN and d1 were found (ra=-0.668; -0.763, p<0.005). Conclusion: Extraction orthodontic treatment showed a good control for facial protrusion cases, making the patients profile more attractive and harmonious. Changes in position and inclination of anterior teeth were also related to changes of facial soft tissues. There is no significant collapse in buccal and temporal region of patients with teeth extraction treatment compared with those without teeth extraction.

La impactación de un órgano dentario es uno de los motivos estadísticamente más comunes en la práctica diaria y su resolución ortodóncica sigue siendo un reto para el Especialista, donde un canino ocupan el segundo lugar de los dientes impactados más frecuentes con una incidencia que oscila entre el 0,8% y el 5.9%, con una relación de 3:1 para la impactación palatina y vestibular y con una frecuencia 2 veces mayor en mujeres que en hombres. Se realizo una búsqueda en diversas bases de datos digitales como: Pubmed, SciencieDirect, Google Scholar, Scopus, Lilacs, Cochrane Library, Web of Science, Epistemonikos, Sage, ProQuest, y se restringió a artículos publicados desde el año 2018 hasta el 2023 sin límite de idiomas. Se aplicó la lista de verificación PRISMA, con la cual se obtuvieron y revisaron 30 artículos aptos para esta revisión. Finalmente, la literatura disponible revela que un diagnóstico preciso, una localización cuidadosa del canino impactado, una elección correcta del abordaje quirúrgico, una fijación estable y confiable del accesorio de ortodoncia, la dirección y magnitud correcta de la fuerza aplicada y un manejo conservador de los tejidos blandos conducen directamente al éxito del tratamiento.
