Endosseous implants have been used to provide anchorage control in orthodontic treatment without the need for special patient cooperation. However these implants have limitation like space requirement, cost, equipments. Recently titanium micro-implant for orthodontic anchorage was introduced. Micro-implants are small enough to place in any area of the alveolar bone, easy to implant and remove, and inexpensive. In addition, orthodontic force application can begin almost immediately after implantation. The mandibular first, maxillary first, mandibula second, and maxillary second molars were the four most commonly missing teeth in adult sample. In case of posterior molar teeth missing, deflective contacts in any position, over time, has produced pathologic change of occlusal scheme because of extrusion of opposing teeth. This case had interocclusal space deficiency by mandibular right molars missing over time. The micro-implants had been used for intrusion of maxillary right molars for interocclusal space. The micro-implant would be absolute anchorage for orthodontic movement. Therefore, the micro-implant would be effective method for correction of occlusal plane.

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.

Tooth ankylosis is frequently resulted from trauma. If indicated, surgical correction is useful osteotomy is one of the method orthodontic surgery that realigns each tooth to the desirable position by using interdental alveolotomy. This method is being adapted when conventional orthodontic of tooth ankylosis on the anterior maxilla via unitooth osteotomy with literature review.

The purpose of this study was to evaluate the factors affecting self - esteem of orthodontic patients. The factors affecting the self - esteem of the orthodontic patients were monthly incomes, and the factors influencing the necessity of orthodontic treatment were the highest at 20-25 years of age. The factors affecting the self - esteem of the orthodontic patients were the order of correction (β= 0.186), dental treatment satisfaction (β= 0.236), interpersonal relationship (β= 0.407), and the explanatory power of the model was 27.6%. Based on these results, it is necessary to continuously study the psychological characteristics to improve the recognition of the need for correction of orthodontic patients, the satisfaction of dental treatment, and the interpersonal relationship.

Early orthodontic treatment in growing children requires the removable orthodontic appliances. The removable orthodontic appliance can be used in the primary dentition and mixed dentition. The purposes of use of removable orthodontic appliance in prmary dentition or mixed dentition are the interception of skeletal or dental malocclusion, guiding the normal dentition, and retention after comprehensive orthodontic treatment. Therefore, it is needed to use the removable orthodontic appliance in children with malocclusion. This report presents cases of growing children with skeletal class II and III malocclusion treated with removable orthodontic appliance during mixed dentition and Multiloop Edgewise Arch Wire(MEAW) during permanent dentition. The results obtained through these cases were summarized as follows : 1. Removable orthodontic appliances guide normal dentition and skeletal growth in growing children. 2. Removable orthodontic appliances play an important role in intercepting malocclusion in mixed dentition before use of fixed orthodontic appliance. 3. MEAW can be applied to finishing stage of all cases and is effective in correction of occlusal plane, achievement of interdigitation, and control of dental inclination. 4. It is needed that removable appliances are used during mixed dentition through correct diagnosis and fixed appliance are used in permanent dentition.

Gingival recession is one of the common mucogingival problems during the orthodontic treatment. The causes of the gingival recession are similar to gingival recession in patients with periodontal diseases. Accumulation of bacterial deposits around the natural teeth induces the gingival inflammation and gingival recession occurs in the teeth with the lack of the supporting bone. However, malpositioned teeth which are labially positioned teeth or rotated teeth are more risky for gingival recession. Once root is exposed to oral cavity due to gingival recession, the orthodontic tooth movement is compromised and esthetic problems appeared. In addition, excessive gingival recession over the mucogingival junction jeopardizes the oral hygiene control, which has a risk of further gingival recession and bone loss around the tooth. To cover exposed root or to prevent further gingival recession, mucogingival surgery with gingival graft is recommended for the patients under orthodontic treatment. This case report aimed to present the mucogingival treatments of gingival recession observed during orthodontic treatment. Case I had had initial slight gingival recession before the orthodontic treatment. However, during the retraction phases, the gingival recession progressed and the periodontal treatment was referred. In case II, miller Class III gingival recession was occurred after correction of rotation. Both cases were treated by coronally advanced flap with free gingival grafts and recovered to the level of adjacent teeth despite of complete root coverage was not achieved in Case II. After periodontal treatment, orthodontic treatment was successfully completed. In conclusion, mucogingival surgery during the orthodontic treatment is recommended for the successful orthodontic treatment as well as periodontal health.

The purposes of early orthodontic intervention are to correct obvious problems, to intercept developing problems and prevent them from becoming worse. Myofunctional influence on facial growth and the dentition change in muscle function and initiate morphologic variation in the normal configuration of the teeth and enhance an already existing malocclusion. Myofunctional therapy has been advocated since 1960's as the treatment for tongue thrust and other oral habits. Pre-orthodontic $TRAINER^{(R)}$ is introduced as functional device usable in children of mixed dentition to correct functional problems concerning soft tissue, tooth and skeleton. The most common cases to treat with Pre-orthodontic $TRAINER^{(R)}$ are lower anterior crowding, anterior open bite, Class II malocclusion and deep bite. Also, it can be used as correction of oral habits. Patients in this cases visited Department of Pediatric Dentistry, School of dentistry, Dankook University for orthodontic treatment. Pre-orthodontic treatment with Pre-orthodontic $TRAINER^{(R)}$ was carried out for correction of the oral habits.

If orthodontists and restorative dentists establish the interdisciplinary approach to esthetic dentistry, the esthetic and functional outcome of their combined efforts will be greatly enhanced. This article describes satisfying esthetic results obtained by the distribution of space for restoration by orthodontic treatment and porcelain laminate veneers in uneven space between maxillary anterior teeth. It is proposed that the use of orthodontic treatment for re-distribution of the space and the use of porcelain laminate veneers to alter crown anatomy provide maximum esthetic and functional correction for patients with irregular interdental spacing.
