Orthodontic treatment is obviously the first choice to get aligned teeth cause of conservative treatment. But it is impossible to get highly esthetic result only orthodontic treatment in case of peg lateralis, discrepancy tooth size, discolored teeth or fractured teeth. As all treatment does, especially in esthetic treatment it is always required interdisciplinary diagnosis and treatment plan; orthodontics, periodontology, prothetics, implant therapy. As also, the treatment should be maintained long-term treatment with stable and harmonious state by esthetic satisfaction and functional occlusion those who needs various dental care as interdisciplinary treatment. This case is the laminate treatment with the orthodontic treatment on 37 ages/ Female patient who has cross bite at anteriors and premolar area and abrasion on centralis at right maxilla. By orthodontic treatment aligned teeth positions, it makes functional occlusion. As laminate treatment with minimum teeth preparation is able to release anterior esthetics. Follow up check for 2 years has been performed since the final prosthetics delivery to the patient. No sign of relapse, fracture of laminate were detected.

Regeneration of interdental papilla damaged by periodontal disease is a very challenging task. So far, many dentists have devised and introduced great surgical methods. Comparing the pros and cons of the methods introduced so far, I came up with the best way to regenerate interdental papilla. Temporarily creating space between narrow interdental papilla, which cannot be solved by periodontal surgery alone, was a great help for connective tissue graft(CTG). The CTG was performed using a microblade, and only one vertical incision was performed off the gingival margin, and the graft was performed by inserting the grafts through here. Along with the orthodontic treatment, the area between the narrow interdental papilla was widened to make it easier for the CTG was carried out. After a period of maintenance, I was able to gather the teeth again with orthodontic force and regenerate the interdental papilla. I named this method ELSA (Enlargement of space-Labial graft-Squeezing-for Augmentation of papilla) technique.

Impaction with a severely dilacerated root is seldom reported, especially in the maxillary incisor. It is probably because of the high clinical difficulty associated with bringing the dilacerated tooth into proper position, and the high chance of failure due to ankylosis, external root resolution, and root exposure after orthodontic traction. Even the successful cases may need periodontal surgery to improve the unesthetic gingival shape. However, it has previously been reported that an impacted maxillary central incisor was successfully treated by proper crown exposure and orthodontic traction. This article presents a case of an invertedly impacted maxillary right central incisor with a developing dilacerated root, which was aligned into proper position after orthodontic traction composed of two stages of a closed eruption technique.

Forced orthodontic eruption(FOE) is a non-surgical treatment approach that allows augmenting both soft- and hard-tissue profiles of potential implant sites, by forced orthodontic extrusion of "hopeless" teeth and their periodontal apparatus. By stretching the gingival and periodontal ligament fibers during extrusion, tension is imparted to the entire alveolar socket, stimulating osseous apposition at the alveolar crest. FOE increases the width of the attached gingiva, and the mucogingival junction remains stable when the gingival margin migrates coronally. Based on these effects, FOE of non-restorable teeth prior to implant placement is a viable alternative to conventional surgical augmentative procedures in implant site development. The aim of this case report is to describes coronal soft-tissue augmentation around fractured teeth, which was achieved by FOE before implant placement.

Orthodontic band cements are widely used in the fields of orthodontics, but they are commonly known as cytotoxic material. Within an oral cavity several ions and components are released from orthodontic band cements, thus causing inflammation or injury to the Periodontal tissue. Therefore, it is very important to estimate the biocompatibility of orthodontic band cements. The purpose of this study was to assess the cytotoxic effect of orthodontic band cements to HGF cells. A zinc phosphate cement, a glass ionomer, a resin modified glass ionomer, and compomer were used to evaluate three cytotoxicity assays: cell proliferation assay, MTT assay, and agar ovelay assay The results were as follows: 1. In the cell proliferation assay, Gl>ZPC, RMGI, RMGI24, GI24>compomer24, ZPC24, compomer>metal ring lined up in order of cytotoxicity 2. In the MTT assay, GI>ZPC, RMGI>GI24>ZPC24, compomer, metal ring, RMGI24, compomer24 lined up in order of cytotoxicity. 3. In the agar overlay test, GI>GI24, ZPC, ZPC24, RMGI>RMGI24, compomer, compomer24, metal ring lined up in order of cytotoxicity.

A total of 580 patients, who visited and received an orthodontic diagnosis in the Department of Pediatric Dentistry, Seoul National University Dental Hospital from 2017 to 2019, were investigated in this study. The aim of this study was to evaluate skeletal patterns of pediatric orthodontic patients determined with lateral cephalometric analysis and to analyze the relationship between skeletal pattern and probable associated clinical features. Also, the modality of orthodontic treatment for each skeletal classification was investigated to aid in therapeutic decisions. Patients aged 7 year accounted for the largest age group; 54.2% of patients showed a skeletal class I pattern, 22.2% showed a skeletal class II pattern, and 23.6% showed a skeletal class III pattern. Bi-maxillary retrusion for skeletal class I, retruded mandible with normal positioning of the maxilla for skeletal class II, and retrusion of the maxilla with protrusion of the mandible for skeletal class III were the largest subgroups by skeletal pattern. Brachyfacial type accounted for 55.0% of patients, followed by 31.9% of mesofacial type and 13.1% of dolichofacial type. The prevalence of anterior crossbite in the study was 43.3%, higher than that in previous studies.

The present study surveyed 300 adults who completed orthodontic treatment to determine their oral health-related quality of life and changes in oral health behavior in orthodontic patients. The collected data is analyzed using the spss 22.0 program. Before orthodontic treatment, social factors (4.68) had the lowest associated quality of life score, and after orthodontic treatment, socially related quality of life showed the highest increase at 3.72 points. Changes in oral health behavior showed that many phosphorus scaling increased by 1.28 points after correction compared to before correction. As oral health quality of life and oral health behavior have changed through orthodontic treatment, dental professionals need to take appropriate management of each patient's individual quality through health education. Appropriate management needs to be developed.

Severe cases of mandibular prognathism can be treated with orthodontic therapy or surgical correction, but there are situations where only prosthetic improvement is possible. An understanding of class III patients is needed, including a vertical chewing pattern and the absence of anterior guidance. Additionally, it is relatively easy to increase occlusal vertical dimension to correct the anterior crossbite, but this approach can sometimes lead to unfavorable results, necessitating careful diagnosis and treatment planning. In this case report, oral rehabilitation was conducted in a patient with mandibular prognathism and asymmetry, utilizing implants and fixed dental prosthesis. Through a step-by-step treatment approach, the existing occlusal vertical dimension was maintained, and the final fixed dental prosthesis restoration was completed. Accordingly, it shows functional and aesthetically appropriate results, and reports on the patient's diagnosis and treatment process.

Malocclusion occurs more frequently in Special Health Care Needed (SHCN) patients than those in general. As caregiver's needs for orthodontic treatment tend to increase, the dentist should know how to decide the extent of treatment. This case report is about orthodontic treatment for two SHCN patients; one patient with cerebral palsy, and another patient with autism. A 10-year-old patient with cerebral palsy showed protrusion and rotation of maxillary anterior teeth. To resolve his chief complaints and make better oral hygiene, he underwent orthodontic treatment using micro tube appliances for 6 months. Another 11-year-old patient with autism had anterior crossbite and showed space deficiency of #13 and chronic gingivitis because of poor oral hygiene. She underwent orthodontic treatment with maxillary skeletal expander, facemask and AP expansion appliance. After 18 months we found positive overjet and ended the treatment. When giving SHCNs orthodontic treatment, the extent of treatment can be chosen according to the patient's cooperative ability and the traits of disabilities. Before initiating orthodontic treatment, the caregivers should be aware of their limitations of the treatment. Since oral hygiene is crucial factor in every dental treatment, education of oral hygiene process for the caregivers and SHCN patient must be done before the orthodontic treatment.
