“…Hence, a surgical procedure can realize a reduction of expansion resistance and accelerated fracture of the palatal suture. 9,10,22 However, the results for model B were almost identical to those of model C, indicating that even a simple incision in the lateral wall of the maxilla could weaken the resistance of the craniomaxillofacial bone and accelerate fracture of the midline palatal suture.…”

“…[1][2][3] Surgically assisted rapid palatal expansion (SARPE) has become the primary choice for palatal expansion in adults, [4][5][6][7] but there are controversies regarding the choice of surgical method. [8][9][10] A LeFort I osteotomy (LFIO) can relieve maxillofacial resistance and concentrate the expansion force, and is used commonly for SARPE to accelerate palatal expansion. 5,7,11 A LFIO in SARPE has some disadvantages: the side-effects of general anesthesia, risk of fracture, prolonged recovery period and an injury risk to the pterygopalatine segment of the maxillary artery.…”

Objective: To provide a simplified treatment strategy for patients with maxillary transverse deficiency. We investigated and compared the fracture mechanics and stress distribution of a midline palatal suture under dynamic loads during surgically-assisted rapid palatal expansion. Methods: Based on the cone-beam computed tomography (CBCT) data of a 21-year-old female volunteer, a three-dimensional model of the cranio-maxillofacial complex (including the palatal suture) was constructed. A finite element analysis model was constructed based on meshwork. After the yield strength of the palatal suture was set, an increasing expansion force (0–500 N) was applied within 140 ms to calculate the time–load curve, which mimicked nonsurgical bone expansion (model A). The same method was used to evaluate the fracture process, time and stress distribution of the palatal suture in maxillary lateral osteotomy-assisted (model B) and LeFort osteomy I (LFIO)-assisted expansion of the maxillary arch (model C). Results: Compared with model A, the palatal suture of model B and model C showed a faster stress accumulation rate and shorter fracture time, and the fracture time of model B and model C was almost identical. Compared with model A, we discovered that model B and model C showed greater lateral extension of the maxilla, and the difference was reflected mainly in the lower part of the maxilla, and there was no difference between model B and model C in lateral extension of the maxilla. Conclusions: Compared with arch expansion using nonsurgical assistance (model A), arch expansion using maxillary lateral wall-osteotomy (model B) or LFIO had a faster rate of stress accumulation, shorter time of fracture of the palatal suture and increased lateral displacement of the maxilla. Compared with arch expansion using LFIO (model C), arch expansion using lateral osteotomy (model B) had a similar duration of palatal suture rupture and lateral maxillary extension. In view of the trauma and serious complications associated with LFIO, maxillary lateral wall-osteotomy could be considered a substitute for LFIO.

“…Aligners transmit pressure more intermittently and for shorter periods of time when a patient is non-compliant, which lowers the risk of root resorption [35]. However, they can also produce jiggling forces [40,[80][81][82][83]. This is not commonly reported [38], as determining its occurrence is difficult [38,81,[84][85][86][87].…”

A variety of metals and alloys are employed in the field of orthodontics, of which the construction of wires happens to be predominant. Through this systematic review, our primary goal was to review and assess studies focusing on complications that emerged during or directly after the completion of an orthodontic treatment plan. We then used a meta-analysis to determine how these complications affected the patients who were receiving orthodontic treatment. A total of 634 documents were discovered after a thorough search of online journals, and 416 of the papers were initially selected. In the end, 14 papers, including in vitro experiments, literature reviews, comparative analyses, observational studies, and retrospective studies, were chosen that met the requisite inclusion and exclusion criteria. There were difficulties related to orthodontic treatment in all of the studies listed in our systematic review, but their severity varied greatly. The effects of gingival mucosa and root resorption were two of the most often mentioned periodontal problems in this review. More long-term studies are required to confirm the involvement of an orthodontic component in these issues, but the majority of the complications were assessed to initially arise after the treatment plan had begun and to resolve with time.

“…The time required for the surgical groups to fracture the palatal suture was significantly shorter than that for the nonsurgical group. Hence, a surgical procedure can realize a reduction of expansion resistance and accelerated fracture of the palatal suture [ 9 , 10 , 25 ]. However, the results for model B were almost identical to those of model C, indicating that even a simple incision in the lateral wall of the maxilla could weaken the resistance of the craniomaxillofacial bone and accelerate fracture of the midline palatal suture.…”
