Orthognathic surgery and orthodontic treatment are required for patients with dentofacial deformities to obtain an ideal facial esthetic with good functioning. Recently, characterized by the surgery-first approach, an integrated orthodontic–surgical treatment has been introduced as an emerging solution to dentofacial deformity treatment. The surgery-first approach is regarded to have less treatment time and quicker enhancement of a facial profile than the conventional orthodontic–surgical treatment. Moreover, the recent advances in computing and imaging have allowed the adoption of 3-dimensional (3D) virtual planning protocols in orthognathic surgery as well as digital orthodontic treatment, which enables a paradigm shift when realizing virtual planning properly. These techniques then allow the surgeon and orthodontist to collaborate, plan, and simulate the dentofacial deformity treatment before performing the whole procedure. Along this line, in this research article, we present an integrated treatment method for the realization of an effective deformity treatment. Specifically, we implemented the integrated 3D technique by combining it with the surgery-first orthognathic approach (SFOA) as a novel treatment method for the patients. The outcomes from the combined treatments of the patients with dentofacial deformity, in practice, have demonstrated that our proposed 3D technique in orthognathics and orthodontics using clear aligner therapy (e.g., Invisalign) can enhance the satisfactory level of the patient since the start of treatment then improve their quality of life. As a result, the combined techniques realize the novel integrated treatment method using 3D technology with the use of 3D imaging and modeling as a promising development trend of dentistry, which fits into the context of Dentistry 4.0 as a key enabler to the concept of sustainable dentistry development.

Introdução: a macroglossia é uma condição incomum e pode ser caracterizada como uma desordem por hipertrofia muscular, podendo ter também origem tumoral, endócrina, causas congênitas e doenças adquiridas. Inúmeras são as técnicas cirúrgicas para correção desta anomalia, porém, o plano de tratamento deve ter como base a etiologia da macroglossia. A correção cirúrgica objetiva a retomada de forma e função da língua, reestabelecendo a capacidade mastigatória, respiratória, fonética e estabilidade oclusal. Objetivo: relatar a comunidade científica um caso de glossectomia parcial para correção de um quadro de macroglossia, facilitando assim, a estabilidade do tratamento ortodôntico do paciente. Relato de caso: Paciente de 50 anos, leucoderma, em tratamento por ortodontia corretiva há mais de 18 meses, sem sucesso observado. Devido ao quadro de instablidade ortodôntica, maloclusão sem resolução passiva, macroglossia diagnosticada e redução da capacidade respiratória foi optado por realizar a glossectomia parcial. O procedimento foi realizado sob anestesia geral, onde removemos o tecido muscular a partir da abordagem de buraco de fechadura (Técnica de Kole). Conclusão: constatamos no presente caso, que a técnica de buraco de fechadura empregada neste paciente se mostrou eficaz, uma vez que obtivemos uma melhora estética e funcional, diminuindo o comprimento e largura da língua. Da mesma maneira, o tratamento ortodôntico foi passível de ser finalizado.Descritores: Macroglossia; Cirurgia Bucal; Glossectomia.ReferênciasTopouzelis N, Iliopoulos C, Kolokitha OE. Macroglossia.

Facial asymmetry, following early childhood condylar trauma, is a common complaint among patients who seek surgical treatment. G.D.M., a 27-year-old male patient, sought professional help to correct his cosmetic flaw, caused by a condylar fracture when he was 8-years-old. After the proper orthodontic treatment, he underwent a double jaw orthognathic surgery and, 9 months later, a second one to correct the remaining asymmetry. Two years after this second procedure, the patient is still under surveillance and has no complaints.

Summary Introduction. Although severe root resorption is rare, it is a side effect of orthodontic treatment which affects tooth prognosis. Patients with severe dentofacial deformity, for whom orthodontic treatment and orthognathic surgery was done at the age of 18 and later, had long duration orthodontic treatment and orthognathic surgery, and are at a high risk of root resorption. The impact of orthognathic surgery on root resorption has not been sufficiently studied, and therefore is an interesting topic to research. Aim of the Study. To identify the risk factors for apical root resorption of maxillary incisors and canines as a result of orthodontic and surgical treatment of Class III malocclusion involving LeFort I osteotomy. Material and methods. The root lengths of upper incisors and canines were measured on cone beam computer tomography (CBCT) scans obtained from a database of orthognathic surgery patients. As a criteria for root resorption was chosen the difference in root lengths between different time points. The measurements were performed using the scans taken before orthodontic treatment (T1), before surgery (T2), and after post surgery orthodontic treatment (T3), of 28 subjects, aged 20.5 ± 3.81 years, with the mean presurgery treatment time of 19.9 ± 8.8 months, and post-surgery time of 7.1 ± 3.1 months. Changes in root lengths during different time spans were correlated with treatment duration, the initial crown/root ratio, and the severity of dentofacial deformity (Wits appraisal, ANB angle, and overjet). Results. During T1 - T2 the roots of the lateral incisors shortened by a maximum of 0.78 ± 0.83 mm (p < 0.001), at a rate of 0.04 mm per month. During T2 - T3 the lengths of the central incisor roots decreased most by 0.49 ± 0.52 (p < 0.001) at a rate of 0.07 mm per month. The resorption speed for canines increased from 0.03 mm to 0.1 mm per month before and after surgery. There were statistically significant correlations between the crown-root ratio and the incisor root length (r = 0.319 for lateral and r = 303 for central, both p<0,05) and for canines (r = 482, p<0.01). The associations between the shortened root length, in different time spans for different teeth, and the severity of malocclusion were inconsistent. Conclusions. Overall, the shortened root length during combined orthodontic and surgical treatment might not be clinically significant. After surgery, the rate of root resorption (mm per month) increased, especially for canines. The teeth with initially shorter roots showed more resorption during treatment.

Despite the high level of development of modern surgery and pharmacology, none of the surgical techniques (hysterectomy / myometectomy or embolization of the uterine arteries) or drug therapy is not a guarantee of the absence of a future recurrence of uterine fibroids and endometriosis. However, there are methods of effective pharmacotherapy for their manifestations. In particular, selective progesterone receptor modulators (SMPR) demonstrate high efficacy in respect of the symptoms of myoma and the size of the nodes, which allows them to be considered as a complete alternative to the surgical treatment of uterine fibroids. The objective: evaluation of the effectiveness of the use of SMPR in the treatment of combined gynecological diseases. Patients and methods. The study included materials for the observation of 40 women 20–52 years old with uterine myoma against the background of combined gynecological pathology (endometriosis, infertility), which carried out the enucleation of myomatous nodes by laparotomy, laparoscopic or transcervical access. Patients were divided into two groups. In the main group (n=20), women received SMPR – ulipristal acetate (UPA) 5 mg daily for 3 months. The UIA's bioavailability is 70%. The optimal therapeutic single dose for the analyzed pathology is 5 mg. After 3 months, the first assessment of the effectiveness of the drug with combined gynecological pathology was conducted, then 14 women were exposed to surgical treatment, and 6 of 20 patients continued conservative treatment for another 1–4 months. After the operation to prevent the recurrence of uterine fibroids and endometriosis, 8 patients continued treatment of UPA for 4 months. In the comparison group (n=20), women underwent surgical treatment at similar rates, but the SMPR was not assigned to surgery. Results. Of the studies indicate that the use of such a selective modulator of progesterone receptors, like vandalite acetate, in the treatment of uterine myomas in combination with endometriosis is safe and well tolerated, leads to rapid persistent coping of uterine bleeding, a significant decrease in the size of nodes and foci of endometriosis, and the achieved The therapeutic effect is maintained even after the abolition of therapy. Conclusion. Thus, the use of the drug ulipristal acetate in the treatment of uterine fibroate on the background of combined gynecologic pathology is highly effective and promising as an independent and integrated treatment method of this category of patients. Key words: uterine myoma, endometriosis, selective modulators of progesterone receptors, viperpatel acetate, combined oral contraceptives.

IntroductionTwo surgical approaches exist for malocclusion: in the surgery-first approach the orthognathic surgery precedes the orthodontic treatment, treating facial esthetics first and then occlusion, whereas in the conventional approach (the orthodontics-first approach) the orthodontic treatment precedes the orthognathic surgery, treating occlusion first and then facial esthetics. The advantages of the surgery-first approach include the fact that patient's dental function, and facial esthetics are restored and improved soon after the beginning of treatment. Moreover, the entire treatment lasts only 1 to 1.5 years or less and orthodontic management is easier to achieve.AimsOur study aims to compare patients undergoing surgery-first or orthognathic surgery approach as for as self-esteem, satisfaction with their appearance in the pre- and postoperative care, quality of life and psychosocial changes, are concerned.MethodsWe recruited 50 patients undergoing surgery-first or orthognathic surgery approach at SC Maxillo-Facciale of Novara between October 2014 and December 2017. Assessment were performed at baseline (T0) and at follow-up (T1: 5 weeks; T2: 5–6 months), with Rosenberg Self-Esteem Scale (RSES), Temperament and Character Inventory (TCI: only at T0), Short Form Health Survey 36 (SF-36), Beck Depression Inventory (BDI-II), Resilience Scale for Adult (RSA), Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), Oral Health Impact Profile (OHIP-14).ResultsData collection is still ongoing. We expect to find a better quality of life and higher self-esteem in patients undergoing surgery first approach.ConclusionSatisfaction is crucial for patients’ adherence to treatment and to avoid revolving door. Clinical implications will be discussed.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Backgrond: Until now, there have been many studies on the postoperative stability of orthognathic patients treated with traditional fixed orthodontic appliances. Recently, the use of clear aligners as orthodontic appliances has increased in orthodontic treatment for aesthetic and patient convenience. The aim of this preliminary study was to investigate the stability and characteristics of patients undergoing orthognathic surgery using clear aligners. Patients and Methods: This study was performed on patients who underwent orthognathic surgery by one surgeon at Pusan National University Dental Hospital from April 2017 to August 2021. A comparative study was conducted on five patients treated with clear aligners during orthodontic treatment and ten patients treated with traditional fixed appliances as a control group. Postoperative skeletal changes and recurrence were evaluated by cone beam computed tomography and lateral cephalometric radiographs taken two days postoperatively and six months postoperatively. Several measurement variables were used to confirm the presence or absence of recurrence, preoperative and postoperative orthodontic treatment period, and the number of extracted teeth. Results: Postoperative stability for six months after surgery was not significantly different between the clear aligner group and the traditional fixed appliance group. The preoperative orthodontic treatment period was also shorter in the clear aligner group, and the number of extracted premolar teeth and impacted teeth were also fewer in the clear aligner group, but there was no significant difference. Conclusions: Orthodontic treatment using clear aligners continues to develop, and it is believed that there is no limit to what can be accomplished during orthodontic surgery accompanied by clear aligners.

ABSTRACT Dentofacial deformities usually are surgically treated, and 3D virtual planning has been used to favor accurate outcomes. Cases reported in the present article show that orthognathic surgery carried out to correct facial asymmetries does not comprise only one treatment protocol. 3D virtual planning might be used for surgical planning, but it should also be used to diagnose the deformity, thus allowing for an analysis of the best-recommended possibilities for the orthodontic preparation that suits each individual case.
