Diagnosis and treatment of retained teeth becomes necessary in order to avoid later complications jeopardizing the integrity of the dental arch. To this end a multidisciplinary work is instituted comprising from the early evaluation of the tooth until it is perfectly aligned in the arch, using the Orthodontics and Surgery services.
To apply traction to the upper right ortodonciia and to appropriately position it in the arch. Female patient, mesofacial, ortkdoncia upper right canine, upper arch with a triangular shape and the lower one reteniros a squared shape; severe crowding in both arches, the patient shows lateral upper incisors in crossbite, lower dental midline deviated to the left, ortodnocia class I on both sides and canine class not assessable on either side.
Full fixed appliances offer an option frequently used with traction applied to center of the alveolar process, using wire ligature from the buttons to the rigid archwire; this technique assures a good control system.
Traccionar el canino superior derecho y posicionarlo adecuadamente en la arcada. Included dental organs may cause lesions to neighboring teeth, infection or cysts and represent a difficultproblemdue to its esthetic and functional implications.
The orthodontist has several therapeutic options but to achieve success it is essential to diagnose the dental impaction early. A retained canine is defined as the canine that, having reached its retehidos time for eruption 11 to 13 years old for the upper and 10 to 11 years old for the lower and its full development formed tooth remains included or retendios inside the maxilla or mandible, keeping its pericoronary sac intact.
This impaction can be intraosseous covered by bone or submucosal covered by gingiva. It is more common in the upper canine than in the lower. The more frequently impacted teeth are the upper and lower third molars followed by the lower ortodoncis premolars, the upper canines and the upper central incisors.
Its incidence varies from 0. Therefore ectopic canines represent the third most frequently included and retained teeth. It occurs more frequently in women 1.
CANINOS RETENIDOS EN ORTODONCIA by Anyu Maccagno on Prezi
Most patients require surgical intervention, removal, surgical exposure or transplant; with or without orthodontic traction to achieve a correct alignment when the early extraction of the deciduous canine had no success.
The best option is surgical exposure of the teeth and orthodontic tradition for its best positioning. This treatment must be performed early to prevent damage to the adjacent teeth, asides from being able to upright the canine when it is still high in the vestibule in the case of labial retentions.
The prognosis for moving retained teeth depends on a variety of factorssuch as the position of the retained tooth according to the adjacent teeth, its angulation, distance to be moved, root dilacerations and possible ankylosis or root resorption.
In general, horizontally retained canines, ankylosed canines or canines close to incisors in the horizontal plane otodoncia located more apically are the most difficult to manage or the ones with the poorest prognosis and therefore may need to be extracted; likewise, the chances for canjnos are reduced with age.
Complete fixed appliances offer a commonly used alternative with the traction applied by means of an elastomeric chain or elastic thread or with a rigid arch wire.
This technique offers a good control system. Mesofacial patient with a straight profile, slightly retrusive chin and slight protrusion of the lower lip. Her nasolabial angle is 90 degrees. A slight hyperactivity of the mentalis muscle is observed Figure In the intraoral examination, the patient presents absence of the upper right canine, triangular upper arch and squared lower arch.
Severe crowding is observed in both arches and the upper lateral incisors present an anterior crossbite. She has a 4 mm. The lower dental midline is deviated to the left. She is a molar class I on both sides and the canine class is non-assessableon both sides as well Figure On the panoramic radiograph we observed the retention of the upper right canine, eruptingupper and lower permanent second molars and included caninod third molars Figure Pretreatment panoramic and lateral headfilms.
The cephalometric analysis revealeda skeletal class ipatient due to retrognathia with vertical growth, lower dental protrusion and proclination and narrow airways. Skeletal class II due to retdnidos mandible.
Straight profile with hyperactivity of the mentalis muscle. Crossbite of the upper lateral incisors Figure 4. Deviated lower dental midline. Severe crowding on both arches, triangular upper arch and squared lower arch.
Lower dental protrusion and proclination. Improve the inclination of the lower incisors. Extraction of upper and lowerfirst premolars. Lower canine to canine fixed retention and circumferential retainer on the upper. A Hyrax-type expansion screw was placed to correct the upper arch form. It was activated V turn by day and V turn by night for 12 days Figure 5. Once the expansion was accomplished, the screw was fixated with wire ligature and left for retention for a period of 3 months Figure Afterwards, the patient was referred to surgery for the surgical exposure of the upper right canine and placement of a lingual button to initiate orthodontic traction Figure 7.
The Hyrax was removed and the patient was referred to the surgeon for the extraction of the upper and lower premolars. Surgical approach for button placement. Edgewise appliances, bands on upper and lower first molars with upper double tubes and lower single tubes were placed. We placed a 0. The upper left lateral incisor was ligated proximally with an elastic thread.
Canine distalization was initiated with passive lacebacks Figure Afterwards, the upper left and the lower canines were moved distally with an elastomeric chain, the lingual button was removed from the upper right canine and replaced with a bracket.
Leveling was continued with 0. After space closure, an 0. Fixed appliances were removed and we placeda fixed lower retainer from canine to canine and a circumferential retainer on the upper arch Figure 12 and The button is removed and an upper right canine bracket is placed. With this treatment we managed to performa successful orthodontic traction of a retained canine and position it correctly in the maxillary dental arch Figures 14 to 16 while obtaining: Postreatment panoramic and lateral radiographs.
The management of a retained maxillary canine is not complete with just its alignment; final reetnidos health is a fundamental key to assess treatment success for the maxillary retained canine.
Several strategies for the interceptive treatment of the displaced canine have been proposed but in animpaction case a surgical-orthodontic approach is required.
On this matter, caninod needs to be said that the present clinical case was treated with the same standard surgical-orthodontic approach with the purpose of guiding the retained canine towards the center of the alveolar bone in the maxillary arch. This technique allows the repositioned canine to be surrounded by a physiological amount of gingiva at the end of orthodontic treatment.
This result is similar to the findings of the longitudinal research done by Quirynen et al. It is fundamental to know the location of retained and included canines before their surgical exposure. When the treatment was finished, positive changes were achieved by performing the orthodontic traction of the upper right canine and positioning it correctly in the dental arch. The radiographic characteristics prior to treatment assessed in the panoramic radiographs are useful indicators for the duration of the orthodontic traction but they are not valid predictors for the final periodontal status of the orthodontically repositioned impacted canine.
Complete fixed appliances are a commonly used alternative in combination with traction applied to the center of the alveolar process and the use ofa lingual button and ligature wire tied to the rigid arch wire.
