The lingual multibracket appliance was developed to overcome the unesthetic nature of traditional fixed orthodontic labial appliances; however, treatment with this appliance was regarded as very difficult as well as a time-consuming. Recently, these problems have been reduced because of advances in lingual bracket systems, improved indirect bonding technique and the development of more flexible wires. There has been a marked increase in the number of adults desiring orthodontic treatment over recent years and many of these patients tend to seek invisible orthodontic appliances due to esthetic reasons. Although the lingual multibracket treatment is not ideal, this form of treatment is currently the best option for the patients with esthetic concerns. Here, I would like to present a case treated successfully with lingual multibracket appliance.

Orthodontic extrusion is usually performed by means of a fixed orthodontic appliance that utilizes arch wire attached to adjacent teeth and transfers the desired force by elastic from the wire to the root. However, clinicians often encounter cases where the bonding required for tooth traction is not possible because the adjacent teeth have been restored with ceramic or veneer. The purpose of this case report is to describe a modified orthodontic extrusion appliance that is useful when conventional orthodontic treatment is not possible. The modified appliance was fabricated using an artificial tooth, clear plastic sheeting, and a braided fiber-reinforced composite strip that covered adjacent teeth without bonding. It satisfied the esthetic and functional needs of the patient and established the optimal biologic width.

저자는 3명의 제1급 부정교합 환자를 소구치 발치를 동반하여 설측교정장치로 치료한 결과 비교적 만족할 만한 치료결과를 얻을 수 있었다. 설측교정장치에 의한 치료는 순측장치에 의한 치료보다는 적절한 치아이동에 어려움이 있으며 아직 해결해야 할 많은 문제점이 있으나 향후 재료 및 치료기술의 개발로 대부분의 문제점들이 해결될 수 있을 것으로 생각한다. 앞으로 설측교정장치는 교정치료동안 심미성인 문제로 교정치료를 포기하는 많은 사람들에게 교정치료에 대한 동기유발과 함께 기회를 제공해 줄 수 있는 미래의 교정치료장치라고 생각한다.

매복치는 기능적, 심미적 장애 뿐 아니라 인접치의 치근흡수 등의 문제를 유발할 수 있으므로 적절한 처치가 필요하다. 매복치의 치료 방법으로는 주기적 관찰, 외과적 노출술, 외과적 노출 후 매복치를 교정하는 방법, 치아이식술, 발치 등이 있다. 이 중 교정적 견인에 사용되는 modified Nance appliance는 환자의 협조를 필요로 하지 않으면서, 견인 와이어를 쉽게 교체할 수 있어서 임상적으로 유용하게 사용될 수 있다. 본 증례들에서 modified Nance appliance를 사용하여 전치, 견치, 대구치 등 상악 내 다양한 위치에 존재하는 매복치의 수술을 동반한 교정적 견인을 시행하여 양호한 결과를 얻었기에 보고하는 바이다.

A clear overlay appliance is a type of a removable appliance made from transparent thermoplastic plastic film that covers the entire dentition to move the teeth. It is one of the most favored orthodontic methods opted for by adult patients; this treatment is esthetic, does not cause discomfort and allows oral hygiene to be easily managed when compared to other conventional fixed treatment methods. However, the use of clear overlay appliances, such as invisalign or clear aligner, is associated with various clinical challenges. In particular, the appliances require longer treatment periods compared to fixed treatment, and due to the structural characteristics of the appliances, it is difficult to make proper posterior occlusion and certain type of tooth movement, including extrusion, rotation and tip. Thus, the clear overlay appliances are regarded as supplementary appliances by most orthodontists and have been used for simple orthodontic treatments, such as partial anterior alignments or orthodontic relapse cases. Owing to the remarkable advancement in the field of 3D digital technology over a period of 15 years, the accuracy and convenience of modern clear overlay appliances have continuously improved. Moreover, orthodontic outcomes have also been greatly improved by the introduction of new materials and successful application of various biomechanical methods from conventional orthodontic treatments in the design of clear overlay appliances. This study investigates the clinical limitations that should be considered during the application of clear overlay appliances and also examines the efforts and methods used to overcome these challenges.

Patients who have impacted tooth are found commonly in orthodontic treatment. Although it is difficult to find the cause of impacted teeth, the most common, causes are prolonged retention of the deciduous teeth, trauma, aberrant sequence of eruption, lack of space and deficiency of Vitamin D. Impacted teeth may lead to esthetic and functional problems and root resorption of adjacent teeth, so we should treat it as soon as possible. Commonly used treatment method is the following: After surgically uncovering of the impacted teeth, a bond of orthodontic appliance is established, and orthodontic traction is started with a removable or fixed appliance. We used the modified lingual arch with a soldered auxiliary appliance in lingual arch for traction of lower impacted teeth. The modified lingual arch could control the magnitude and direction of the applied force with one-arch treatment, and also could give continuous force to impacted tooth without patient patient cooperation. We achieved good results with the modified lingual arch.

The orthodontic surgery including lingual orthodontics has recently attracted a person's attention due to its functional and esthetic appreciation. The skeletal anchorage with the miniscrew is newly adopted in the lingual orthodontics to assist the upholding ability. The appliciation needs to understand the mechanism of the orthodontic appliance and its related orthodontic correction for optimal orthodontic treatment. There is, however, few information about the qualitative and quantitative effect of the orthodontic appliance with the miniscrew has not been well identified. In this paper, three dimensional finite element analysis is introduced to the lingual orthodontics in order to investigate the effect of the anterior retraction force on the miniscrew and transpalatal arch wire. The analysis determines the adequate location of the miniscrew and the point of force application of the anchorage system in the lingual orthodontics. The analysis results demonstrate the effect of the position of the miniscrew and the transpalatal arch wire on the lingual orthodontics.

Cleft lip and palate is the most common malformation in the craniofacial region. The patients with cleft lip and palate have functional problem such as, speech, feeding and respiratory as well as esthetic problem. So, treatment should be done by multidiciplinary team approach. The role of pediatric dentist in the team is advicement for feeding method, guidance of normal growth, caries control and preventive orthodontics. In cleft lip and palate patients, maxillary arch after cheiloplasty is usually collapsed by excessive tension of the scar. This collapse increase the difficulty of later orthodontic treatment. Therefore, the maxillary arch segments should be moved and retaind to normal position as soon as cheiloplasty is done to reduce the need and difficulty of orthodontic treatment. This concept is called by the early orthopedic treatment in cleft lip and palate. Also, this orthopedic appliance works as feeding applince to normal feeding and weight gain We reported two cases of early orthopedic treatment with favorable result in complete bilateral cleft lip and palate patients after cheiloplasty. Patients showed normal weight and their maxillary arch widths were increased.
