“…Paunonen et al [ 8 ] reported a skeletal relapse rate as high as 25%, which was significant following BSSO advancement surgery despite insignificant dental alterations. This finding highlights the importance of dental relapse and its compensation by the postoperative skeletal relapse [ 7 ].…”

“…Considerable amounts of research have been conducted to investigate the effect of surgical variables such as different surgical approaches and fixation methods on the occurrence of postoperative relapse [ 4 ]. Some relevant recent studies have also mentioned the effects of some non-surgical confounding factors such as the mandibular plane (MP) angle, the magnitude of advancement, and counterclockwise rotation on the extent of post-surgical relapse [ 2 , 3 , 5 – 7 ].…”

Background The stability of the results remains a significant concern in orthognathic surgeries. This study aimed to assess the amount of relapse following mandibular advancement with/without maxillomandibular fixation (MMF). Materials and methods A single-blind clinical trial was conducted on patients with mandibular retrognathism who underwent BSSO for mandibular advancement and Lefort I maxillary superior repositioning. Patients were randomly divided into two groups of treatment (MMF) and control (no MMF). In the treatment group, MMF was performed for 2 weeks; meanwhile, MMF was not performed in the control group, and only guiding elastics were applied postoperatively. Lateral cephalograms were obtained preoperatively (T1), immediately after surgery (T2), and at 1 year postoperatively (T3). The distance from points A and B to the X and Y plane were measured to identify the amount of vertical and horizontal relapse in 1 year as a primary outcome. An independent t-test was applied in order to find differences in outcomes between the control and treatment groups. Results Fifty-eight patients were evaluated in two groups (28 patients in the MMF group and 30 in the no-MMF group). The magnitude of mandibular advancement following BSSO was 7.68±1.39 mm and 7.53±1.28, respectively, without significant difference among the groups (p= 0.68). The mean sagittal and vertical changes (relapse) at point B were significantly different between the two groups at 1-year follow-up after the osteotomy (p=0.001 and p=0.05, respectively). Conclusion According to the results of this study, patients with short-term MMF following BSSO for mandibular advancement benefit from significantly greater skeletal stability in the sagittal and vertical dimensions.

Malocclusions in the vertical plane are more difficult to treat as compared to the malocclusions in the sagittal plane as they often require multidisciplinary (surgical) approach. Skeletal vertical deficiency and excess causes jaw discrepancies in the sagittal vector too due to rotation of the mandible, thus presenting a complex situation which requires astute treatment planning and implementation. In this article, two cases treated with combined orthodontics and orthognathic surgery to treat skeletal class II malocclusion with vertical deficiency and excess are shown and all details of treatment planning are discussed.

“…Otra técnica es la osteotomía sagital bilateral, desarrollada por Tuner y Obwegeser en 1957 con el propósito de dar una mejor función dental, estabilidad y estética facial (Tabrizi, Nili, Aliabadi, & Pourdanesh, 2017;Malekzadeh, 2021;Ter Horst et. al, 2021;Paunonen, Helminen, & Peltomäki, 2018). Sin embargo, esta se puede combinar con otras técnicas como la genioplastia con la finalidad de reducir la recidiva y mejorar el perfil facial (Balasubramanian et.…”

El objetivo de la siguiente revisión es analizar la estabilidad del avance mandibular después de la cirugía ortognática en Clase II esquelética. Se realizó una búsqueda en las bases digitales tales: PubMed, Scopus, Lilacs, Science Direct, Taylor & Francis, SciELO, Web of Science mediante las siguientes palabras clave “Stability orthognathic surgery”,” Mandibular advancement”, “Class II” relacionadas entre sí con los términos booleanos “AND” desde el 2017 hasta el 2022. El tiempo de seguimiento máximo es de 6 años y el mínimo fue 5 meses de en los cuales se reportan recidiva desde 0.1mm a más de 2mm, el sexo femenino fue el más frecuente en todos los estudios. La estabilidad de la cirugía ortognática no depende solamente de la cirugía en sí, sino de su estrecha relación con diferentes factores que ayudan a mantener la estabilidad o conlleva a una recidiva.
