“…Due to lack of nutrition, the cortical repair capacity is compromised, and the cells of the bone marrow are recruited, elevating the degree of tooth movement [ 36 ]. This theory is supported by the results of a previous study that observed no acceleration of tooth movement for 7-mm-deep perforations in comparison to 4-mm-deep perforations, suggesting that increasing the surgical trauma by deepening MOPs is not more effective for the acceleration of tooth movement [ 39 ].…”

Background This single-centered randomized controlled clinical trial aimed to evaluate the effectiveness of micro-osteoperforations (MOPs) in accelerating the orthodontic retraction of maxillary incisors. Methods Forty-two patients aged 16–40 were recruited and randomly assigned into two groups, one which underwent MOPs (MOPG) in the buccal and palatal region of all maxillary incisors immediately before the start of retraction and one which did not (CG). Eligibility criteria included the orthodontic need for maxillary first premolars extraction and space closure in two phases. The primary outcome of the study consisted of measuring the rate of space closure and, consequently, the rate of incisors’ retraction using digital model superimposition 14 days later and monthly thereafter for the next 4 months. The secondary outcomes included measuring anchorage loss, central incisors’ inclination, and root length shortening, analyzed using cone beam computed tomography scans acquired before retraction and 4 months after retraction. Randomization was performed using QuickCalcs software. While clinical blinding was not possible, the image’s examinator was blinded. Results Twenty-one patients were randomly assigned to each group. However, due to various reasons, a total of 37 patients (17 male and 20 female) were analyzed (mean age: 24.3 ± 8.1 years in the MOPG; 22.2 ± 4.2 years in the CG) during the trial. No statistically significant difference was found between the MOPG and the CG regarding the incisors’ retraction measured at different time points at the incisal border (14 days, 0.4 mm vs. 0.5 mm; 1 month, 0.79 mm vs. 0.77 mm; 2 months, 1.47 mm vs. 1.41 mm; 3 months, 2.09 mm vs. 1.88 mm; 4 months, 2.62 mm vs. 2.29 mm) and at the cervical level (14 days, 0.28 mm vs. 0.30 mm; 1 month, 0.41 mm vs. 0.32 mm; 2 months, 0.89 mm vs. 0.61 mm; 3 months, 1.36 mm vs. 1.10 mm; 4 months, 1.73 mm vs. 1.39 mm). Similarly, no statistically significant differences were detected in the space closure, anchorage loss, central incisors’ inclination, and radicular length between groups. No adverse effect was observed during the trial. Conclusions MOPs did not accelerate the retraction of the maxillary incisors, nor were they associated with greater incisor inclination or root resorption.

FRISBEE RESUMENIntroducción: Existen procedimientos quirúrgicos que pueden generar una disminución en la duración de los tratamientos de ortodoncia (TO) mediante una aceleración del movimiento dental. La técnica más estudiada corresponde a la corticotomía clásica, la cual muchas veces es desechada por los pacientes debido a su invasividad. Es por esto que nacen las intervenciones quirúrgicas mínimamente invasivas (IQMI), tales como las micro osteoperforaciones (MOP) y la piezocisión, que buscan el mismo resultado, pero sin realizar colgajos de espesor total, otorgándole al paciente nuevas alternativas terapéuticas para acortar el tratamiento de ortodoncia. La evidencia al respecto aún es controversial, debido a que la certeza de la evidencia es baja o muy baja con relación a estos procedimientos. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metaanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos 39 revisiones sistemáticas que en conjunto incluyeron 43 estudios primarios, de los cuales, 31 corresponden a ensayos aleatorizados. Concluimos que las intervenciones quirúrgicas mínimamente invasivas podrían aumentar la tasa de movimiento dental a las 12 semanas, la distancia total acumulada, la tasa de movimiento dental y reducir la duración total de tratamiento, pero la certeza de la evidencia es incierta. Además, podrían resultar en poca o ninguna diferencia sobre el índice gingival, la profundidad de sondaje y el índice de placa.

“…Selective alveolar decortication caused a threefold increase in anabolic activity (bone deposition) and catabolic activity (bone degradation) in rats three weeks after corticotomy [ 11 ]. Additionally, osteotomy is a surgical procedure that increases the extent of the injury to both the cortical and trabecular bone and quickens tooth movement [ 12 , 13 , 14 ]. The Le Fort I osteotomy was shown to accelerate alveolar bone remodeling and orthodontic tooth movement in rats [ 15 ].…”

Effect of Extending Corticotomy Depth to Trabecular Bone on Accelerating Orthodontic Tooth Movement in Rats

Corticotomy is a surgical procedure that induces injury to the cortical bone to accelerate tooth movement. This study aimed to increase the depth of corticotomy to the trabecular bone and to evaluate the amount and rate of tooth movement and alveolar bone changes in response to various degrees of cortical and trabecular bone injury. Seventy-eight male Wistar rats were randomly divided into four groups based on procedure used: (1) baseline control group of orthodontic tooth movement (OTM) only; (2) OTM + 4 corticotomies (CO); (3) OTM + 4 osteotomies (OS); and (4) OTM + 16 CO. A closed-coil nickel–titanium spring was placed to move the maxillary first molar mesially with a 10 g force. On days 0, 7, 14, and 21, alveolar bone alteration and tooth movement were measured using microcomputed tomography. Significant tooth movement was related to the number and the depth of the perforations. The OTM + 16 CO group showed a greater amount and rate of tooth movement than the OTM + 4 CO group. When osteotomy and corticotomy were compared with the same volume of bone removed, the OTM + 4 OS group had a faster rate of tooth movement than the OTM + 16 CO group during the first week, with significantly reduced bone volume. However, no significant difference was observed in the amount of tooth movement between the OTM + 4 OS and OTM + 16 CO groups at the end of the study. Extending the depth of corticotomy to trabecular bone increased the amount of tooth movement by accelerating the induction and completion of bone remodeling, which accelerated the rate of tooth movement during the initial stage.
