  • To restore a tooth with a fracture line extending below the marginal bone level, a surgical crown lengthening procedure accompanied by ostectomy could be considered to expose the fracture line and reestablish the biologic width. However, this procedure could lead to esthetic failure, especially in the anterior teeth. Therefore, orthodontic extrusion, which elevates the fracture line from within the alveolar socket without sacrificing the supporting bone and gingiva, is recommended. This technique allows for the proper placement of the crown on a sound tooth structure, with the reestablishment of the biologic width. Alternatively, surgical extrusion is an one-step procedure that is simpler and less time-consuming than orthodontic extrusion; placing and adjusting the orthodontic appliance does not require multiple visits. This study presents successful restoration in 2 cases with a crown-tooth root fracture of the maxillary central incisor treated using a multidisciplinary approach through orthodontic extrusion or surgical extrusion followed by successful restoration.

  • The purpose of this study was to research into the satisfaction with orthodontic treatment and the psychologically satisfactory condition to be expected, and to offer information in order to enhance medical-treatment service, by surveying the influential factors upon satisfaction with treatment targeting patients who receive orthodontic treatment. Targeting 382 patients who are under treatment at S dental clinic in Gyeonggi Province, B dental clinic in Daegu Metropolitan City, and Y dental clinic in Busan Metropolitan City, which specialize in orthodontic treatment, it carried out the direct interview survey of using the structured questionnaire from January 20, 2009 to February 28. The collected data was analyzed by using SPSSWIN 17.0 K. The following conclusions were obtained. 1. In the satisfaction with orthodontic treatment according to aesthetic factor, the group with bad aesthetic health condition was higher than the group with good health condition(p<0.05). As for the factor of tooth alignment, a case of good health condition was indicated to have higher(p<0.05) satisfaction than a case of being bad. 2. As for satisfaction according to necessity for orthodontic treatment, the satisfaction was high in a case of recognizing necessity much and of understanding medical-treatment contents much, and in a case of being well adjusted to the progression of orthodontic treatment. As for a psychological change after orthodontic treatment, the satisfaction was high in a case with a positive change(p<0.001). 3. The factors of influencing satisfaction with orthodontic treatment had significant influence in order of necessity for orthodontic treatment(p<0.001), adjustment to progression of orthodontic treatment(p<0.001), psychological change after orthodontic treatment(p<0.01), expectation level of dental health after orthodontic treatment(p<0.01), and understanding about treatment contents(p<0.01). As a result of research, the satisfaction with orthodontic treatment in patients with orthodontics is indicated to be relatively high. Thus, the careful consideration is considered to be probably necessary on qualitative part in medical treatment and on patients' expectation by grasping patents' mentally psychological condition.

  • One of the most common oral surgical procedures is the extraction of the lower third molar (LTM). Postoperative complications such as paresthesia due to inferior alveolar nerve (IAN) injury are commonly observed in cases of horizontal and vertical impaction. The present report discusses a case of a vertically impacted LTM associated with a dentigerous cyst. An intimate contact between the LTM roots and the mandibular canal was observed on a panoramic radiograph and confirmed with cone-beam computed tomographic (CBCT) cross-sectional cuts. An orthodontic miniscrew was then used to extrude the LTM prior to its surgical removal in order to avoid the risk of inferior alveolar nerve injury. CBCT imaging follow-up confirmed the success of the LTM orthodontic extrusion.

  • Impacted or unerupted permanent teeth have many problems in making a diagnosis and treatment plan in dental clinic. There are several methods to treat impacted teeth. The combination of surgical exposure and orthodontic traction is usually the treatment of choice in cases with impacted teeth. Two cases are reported, which were treated with surgical intervention and orthodontic movement. and one case is treated with orthodontic movement alone. To improve esthetic problem and maintain periodontal health, We should avoid loss of attached gingiva in surgical exposure, and excessive orthodontic force during the traction of the impacted tooth.

  • Patients who have a moderate periodontitis with pathologic tooth migration of maxillary incisors, it is necessary not only periodontal treatment for reduce periodontal inflammation, but also orthodontic treatment to teeth repositioning. For orthodontic treatment, it is necessary to apply less force and careful considerations of the center of resistance of the tooth and optimal force of tooth movement. At this time, the segmental arch applied only to the target teeth, is more effective and predictable, because applied force and direction can be controlled. In addition, to design the orthodontic appliance that can prevent the unwanted tooth movement that used as an anchorage is important. In recent years, various types of skeletal anchorage system have been used for preventing loss of the anchorage. We reported the patient who had extruded maxillary central incisor due to pathologic tooth migration, treated by a successful periodontal-orthodontic multidisciplinary treatment using an orthodontic appliance designed to apply less traumatic force and reduce an anchorage loss.

  • The aim of this study was to evaluate the amount and interrelationship of the soft and hard tissue changes after simultaneous maxillary clockwise rotation and mandibular setback surgery in skeletal class III malocclusion. The sample comprised of 16 adult patients who had anteroposterior skeletal discrepancy. These patients had received presurgical orthodontic treatment and surgical treatment which consisted of Le fort I Osteotomy and bilateral saggital split ramus osteotomy. The presurgical (T1) and postsurgical (T2) lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/PC program. The results demonstrated a decrease in the vertical dimension in the soft and hard tissue. The nasolabial angle was increased and the mentolabial angle was decreased. The results showed also many statistically significant correlations(p<0.05). The lower lip closely followed the skeletal movement of the B- point in the horizontal plane. The double jaw rotation surgery can afford a good solution to solve the problems of class III malocclusion cases.
