The article discusses the application of the IoT concept in the sensitive field of medical devices on the example of a developed prototype of a mechanotherapeutic simulator. Mechanotherapy is a complex of therapeutic, preventive, and restorative exercises conducted using simulators, specially designed for developing movements in individual joints. Mechanotherapy is used for the early and painless restoration of joint mobility, to prevent complications associated with prolonged immobilization of the injured area of extremities. Using the mechanotherapy simulator allows developing the joint painlessly, which accelerates the metabolism in the injured area, and soft tissues are restored to normal. The article provides information about the electronic components that ensure the wireless operation of the device and describes in detail the applied software as well as the client application for a mobile device.

Etiologies and traditional treatment modalities regarding anterior open-bite were discussed to elucidate the advantages and disadvantages. And an emphasis was placed on the understanding of the true nature of anterior open-bite. Most anterior open-bite malocclusions can be treated with a high degree of sucess and stability without surgical intervention with the congnizance of the anatomy, the physiology and the dynamics of orthodontic mechanotherapy. In this regard, a Multiloop Edgewise Arch Wire (MEAW) Technic, which has been developed during the past twenty years by Dr. Kim, was introduced. Three cases with anterior open-bite malocclusion were presented to demonstrate the mechanotherapy.

Long-term posttreatment stability is great concern to all orthodontist. So, this article was disussed that etiology of relapse, classificatioan of retention, duration of retention and treat after relapse. The most important thing about stability was considered that growth pattern, periodontal remodeling, neuromuscular factors and applied the appropriate mechanotherapy. Retenton was considered during the treatment planning and required considerable analytic thought.

Objective: The purpose of this study was to assess the long-term stability of rapid palatal expansion (RPE) followed by full fixed edgewise appliances. Methods: This study included 67 patients treated using Haas-type RPE and non-extraction edgewise appliance therapy at a single orthodontic practice. Serial dental casts were obtained at three different time points: pretreatment ($T_1$), after expansion and fixed appliance therapy ($T_2$), and at long-term recall ($T_3$). The mean duration of the $T_1-T_2$ and $T_2-T_3$ periods was $4.8{\pm}3.5years$ and $11.0{\pm}5.4years$, respectively. The dental casts were digitized, and the computed measurements were compared with untreated reference data. Results: The majority of treatment-related increases in the maxillary and mandibular arch measurements were statistically significant (p < 0.05) and greater than expected for the untreated controls. Although many measurements decreased postretention ($T_2-T_3$), the net gains persisted for all of the measurements evaluated. Conclusions: The use of RPE therapy followed by full fixed edgewise appliances is an effective method for increasing maxillary and mandibular arch width dimensions in growing patients.

Objectives One aspect of undesirable outcomes in orthodontic treatment includes excessive resorption of dental roots with mechanotherapy. The purpose of this study was to examine the relationship between treatment duration, adult and adolescent, gender, extraction and non-extraction root resorption after orthodontic treatment. Methods The subjects consisted of 140 orthodontic patients(adult : 70, adolescent : 70) who treated by standard edgewise technique at the three orthodontic hospital and clinic in seoul. Pre-treatment and post-treatment periapical radiographs were examined. The amount of root resorption was assessed for six anterior teeth according to criteria modified from Lupi et al root resorption score. Results Treatment duration was 24.7 months in the adult group and 33.5 months in the adolescents group. Between adult and adolescents group were significantly difference of mean of root resorption score(p<0.05). Female group and extraction group usually had higher prevalence of root resorption, but were not significant differences between the each groups(p>0.05). Conclusions When viewing these results, a lot of root resorption in adult patients appears, especially the maxillary central incisor, lateral incisor root resorption during orthodontic treatment occurs, so be careful and do more research to be done is suggested.

Impactions can occur because of malpositioning of the tooth bud or obstruction in the path of eruption. However, the exact mechanism is still unknown. The impaction of mandibular first molar is rare with prevalence rates of 0.01~0.25%, but it is important to deimpact the tooth as soon as possible to avoid complications such as dental caries, root resorption, and periodontal problems on the adjacent teeth. Several biomechanical strategies have been proposed for uprighting mesially tipped mandibular first molars. However, most of these have had problems with movement of the anchorage unit because of the reciprocal force. The recent development of skeletal anchorage system(SAS) allows direct application of precise force systems to the target tooth or segment, producing efficient tooth movement in a short time. In this case, an impacted mandibular left first molar with dilacerated roots was treated with a miniplate, which provided skeletal anchorage to upright the tooth. The miniplate was installed in the mandibular ramus, and 10 months after the application of orthodontic force, the impacted tooth was exposed in the oral cavity and uprighted. At this point, the mandibular left first molar was included in the orthodontic appliance with fixed mechanotherapy, the tooth could achieve a normal occlusion. Therefore, the use of SAS simplified the orthodontic procedures and reduced the orthodontic treatment period, and had few side effects.

One aspect of undesirable outcomes in orthodontic treatment includes excessive resorption of dental roots with mechanotherapy. The aim of this study is to demonstrate whether diseases affecting the immune system adversely are prevalent in orthodontic patients who manifest excessive resorption of dental roots with orthodontic tooth movement. The records of 51 orthodontic patients (25 males and 26 females, $16.1{\pm}3.3$ yr old) and 51 pair-matched controls ($1.5.4{\pm}4.1$ yr old) were analyzed retrospectively. The pretreatment questionnaires and the treatment records disclosed that the incidence of asthma, allergy, and signs indicative of psychological stress, was significantly higher in the root resorption cohort. The immune system is either altered or adversely affected in all these conditions. Since the progenitors of osteoclasts and odontoclasts are derived from mononucleated cells of monocyte and macrophage lineage, which are prominent cellular members of the immune system, the study leaded to the conclusion that excessive root resorption may occur in orthodontic patients who are psychologically stressed, or who have asthma and allergy, or any other conditions that may adversely affect and modify the immune system, and a careful examination and interpretation of a patient's medical history may be beneficial to both patient and practioner.
