“…It normally happens in non-extraction cases, leading the soft tissue to move forward. 15 From this case report, it can be concluded that the treatment goal has been achieved to treat the malocclusion with impacted canine. The impacted canine could be retracted with gold chain combined with MBT orthodontic prescription into its physiological position and the patient was satisfied with the aesthetic result and stomatognathic function.…”

Background: Maxillary canines play a critical point in creating an aesthetic smile as they support the part of facial muscle. Canines are also the second most frequently impacted teeth after the third molars. In some cases, it is possible to retract canines into their correct position by orthodontics treatment. Purpose: This article highlighted a treatment option with surgical exposure, in which a maxillary canine was impacted. It presented gradual steps from pre-surgical to post-surgical orthodontic treatment. Case: A 16 years old female patient referred to Orthodontic Department by Oral Surgeon for pre-surgical orthodontic treatment of her impacted maxillary canine. Case Management: After pre-surgical orthodontic treatment, the impacted canine was surgically exposed by closed technique since open surgical exposure might need excessive removal of the surrounding bone. Traction was given through a gold chain which attached to the palatal surface of the impacted canine. The tooth was ideally positioned with fixed orthodontic appliances. The permanent right maxillary canine was successfully positioned into proper alignment with the remaining teeth. Aesthetic smile was improved. Conclusion: Malocclusion with impacted canine was successfully treated with MBT orthodontic prescription combined with gold chain that can retract the impacted canine into its physiological position and the patient was satisfied with the aesthetic result.

“…The minor change caused to mandibular intercanine width can be considered a factor that contributed to increased long-term alignment stability. (5) It is well-known that a Class I canine relationship is important for functional occlusion. In this situation, a canine-protected occlusion became a premolar-protected occlusion during the mandibular lateral or working excursions.…”

Male patient, at age 20, in good general health with no significant medical history. The main complaint was related to missing teeth in the upper arch and crowding especially in the lower arch. Tooth leveling and alignment were completed in 8 months by sequential changing of copper niti wires. At the end of this phase, the anterior overjet was increased, and the molar relationship was still Class I. Space was created between the central incisors and lateral incisors for the prosthetic tooth in the upper arch using open coil spring. Meanwhile, the lower extraction space of the lower incisors was closed by retraction. Space created for prosthetic crown and space closure in lower arch. Once the space was closed the overjet was increased to 2-3mm. And the upper missing central incisor was replaced with the prosthetic crown. Keywords: Single incisor extraction, Reduced overjet, Missing upper incisors, Prosthetic rehabilitation

“…4 Among all the factors contributing to oral-facial esthetics, dental crowding is considered an important issue, encouraging people to seek orthodontic treatment. 5 Dental crowding is a term used to illustrate the presence of dental irregularity or insufficiency of space within the dental arcade; 6 crowding with a discrepancy of greater than 3 mm is considered significant enough to warrant treatment. 7 Theories regarding the etiology of dental crowding are divergent and unclear.…”

Dental crowding is a prevalent problem in modern society. Various factors, including different bracket systems and geometry of wire, influence the outcome using superelastic wire in the alignment stage of treatment. Currently, the use of light round wire instead of large-sized rectangular wire is emphasized to avoid powerful torsional stiffness. However, these guidelines lack scientific evidence for support. They have been written predominantly based on clinical experience. Therefore, the purpose of this study was to evaluate how factors such as bracket systems and wire geometry affect the stress distribution at the root-bone interface. Models using a photoelastic material (PL-3) to simulate bone tissue were fabricated. The simulated teeth were arranged as in lower anterior crowding. Then, the crowded teeth were subjected to orthodontic treatment with various types of bracket, ligating approaches using ligature wires of different sizes, shapes, and materials. Photoelastic images of the bone area of the models were obtained and compared. The results showed that wire size plays a more significant role than the material or cross-sectional shape of the wire in affecting the stress distribution at the simulated root-bone interface. The teeth ligated with a larger cross-sectional diameter of wire showed the application of excessive torque, which may cause root resorption and slow down tooth movement. These results not only demonstrate the scientific evidence backing clinical experience but also can be a useful reference for further clinical application.
