The fundamental principles and the role of surgeons and orthodontists to produce successful results in orthodontic treatment combined with orthognathic surgery is not different from those of conventional procedures and FOS: surgery-first-orthodontic-treatment-later approach. The communication and cooperation between surgeon and orthodontist is of crucial importance. In FOS, the pre-surgical orthodontic preparation is not carried out in the patient's mouth, but in the mounted stone model and in addition to the simulation of tooth movement, to get a precise surgical occlusion, the entire steps of treatment should be simulated on the articulator as well. Right after the surgery, due to the instability of the occlusion, appropriate post operational care should be given according to the surgical technique applied to the mandible by use of final surgical wafer about 8 weeks.

As the demand for natural and beautiful smiles increases, the demand for anterior aesthetic treatment is increasing. Orthodontic treatment is often necessary for esthetic, healthy and natural treatment outcome. Particularly, in the case of middle-aged patients, minor tooth movement limited to anterior teeth is more effective than comprehensive orthodontic treatment which requires a long-term treatment period. Clinician who is in charge of aesthetic dentistry should have the ability to select a case that can be treated with partial orthodontic treatment and to determine the most effective treatment method. This article provides decision flowchart for case selection and choosing the best treatment modality for anterior teeth alignment.

The author measured the degree of development and the eruption pattern of first permanent molars with orthopantomography in 553 Korean children(male; 302, female; 251) from 4 to 9 years old. The orthopantomographs were obtained from dept. of pedodontics, college of dentistry, Seoul National University. The results of the studies were as follows: 1. Upper first permanent molars were erupted with distal inclination of about 30 degrees in the early stage and they gradually moved in the mesial direction by bodily movement of the tooth to be in contact with the disto-proximal surface of primary secondary molars in the late stage. 2. Lower first permanent molars were erupted with mesial inclination in the early stage and moved mesially by tipping movement of the tooth to be in contact with the disto proximal surface of the second primary molars in the late stage. 3. The eruptive forces were considered to be main etiologic factors of space closure after the premature loss of primary molars.

The incorporation of technological advances in the field of clinical orthodontics to increase treatment efficiency has led to the development of customized appliances (Insignia$^{(R)}$), archwires (Suresmile$^{(R)}$), and the production of devices to enhance tooth movement (Acceledent$^{(R)}$). This review presents a comprehensive study of the literature concerning these products, and analyzes the available evidence of their efficiency. To date, one pilot study has evaluated the efficiency of the Insignia$^{(R)}$ system, three retrospective studies have assessed the efficiency of the Suresmile$^{(R)}$ system, and a few Acceledent$^{(R)}$ reports have described its effect on treatment time. Critical appraisal of the reviewed papers revealed that the efficiency of the Insignia$^{(R)}$ system cannot be confirmed based on the available evidence, while the use of Suresmile$^{(R)}$ can reduce overall treatment time in simple cases. The acceleration of tooth movement by Acceledent$^{(R)}$ devices has not yet been confirmed.

A treatment should be functional, esthetic, conservative and periodontally healthy in order to meet criteria of an ideal dental procedure. In a prsthodontic patient with horizontal and/or vertical space deficiency, orthodontic tooth movement should be considered as a pre-prosthetic procedure. With a conventional technique, orthodontic treatment is a time-consuming and uncomfortable procedure. Pre-prosthetic orthodontic treatment, however, is no longer difficult procedure with the help of recently developed techniques, such as passive bracketing. The present article outlines the problems and causes of horizontal and vertical space deficiency in prosthodontic patients, and presents efficient pre-prosthetic orthodontic treatment modalities with typical clinical cases.

Exposing sound structure of a subgingivally fractured tooth using orthodontic extrusion is considered to be a conservative way to re-establish biologic width without sacrificing esthetics or jeopardizing periodontal support of neighboring teeth. When a misaligned tooth is traumatically involved, a more comprehensive approach combining tooth extrusion and re-alignment may be necessary for a successful restorative outcome. This case report describes a successful esthetic management of a patient with complicated crown-root fracture on the maxillary right central incisor and pre-existing malocclusion in the maxillary anterior region. Forced eruption along with re-alignment of teeth by orthodontic movement seems to allow re-positioning of the fracture line to a favorable position and correction of crowding, providing a better esthetic result.
