Intra-alveolar surgical uprighting of impacted teeth: a case report

Canine transposition as an alternative to trauma of the maxillary incisors: case report

Objective:

The present article aims at reporting the clinical case of a patient who suffered trauma at two years of age, causing almost complete apical displacement of the deciduous maxillary left central incisor and of the permanent incisor.

Methods:

Ectopia secondary to intrusion was minimized by surgical removal of the ectopic tooth, and the left permanent canine was submitted to orthodontic traction to replace the extracted tooth.

Results:

The treatment period lasted 36 months, resulting in correct occlusion and a good aesthetic outcome.

Conclusions:

Dental transposition carried out by means of orthopedic traction is a good alternative in cases of a very unfavorable ectopic tooth position.

Influence of repeat surgery on treatment time in the interdisciplinary management of impacted maxillary canines: A retrospective cohort study

PURPOSE

To evaluate the effect of repeat surgery on treatment time in the interdisciplinary management of impacted maxillary canines.

MATERIAL AND METHODS

This retrospective cohort study enrolled patients referred for computed tomographic examination for impacted maxillary canines within a 5-year observational period. The occurrence of repeat surgery was analysed with regard to treatment time, canine location, and surgical exposure technique.

RESULTS

A total of 55 patients with 79 impacted maxillary canines were analysed. Of those, 83.6% did not present with complications that would have prompted repeat surgery during their treatment. For patients requiring repeat surgery, time until clinically visible movement of the canine was significantly longer (p < 0.001), whereas time between initial movement and eruption into the oral cavity was significantly shorter (p < 0.001). Overall treatment time did not differ significantly (p = 0.13). An open surgical exposure technique was associated with a significantly lower occurrence of repeat surgeries (p = 0.03). Bilateral impaction of canines significantly prolonged overall treatment time (p = 0.01).

CONCLUSIONS

In the event of initial treatment failure during the interdisciplinary management of impacted maxillary canines, repeat surgery should be considered, which has limited effect on overall treatment time. An open surgical exposure technique is preferable.

Reimplantation, bone augmentation, and implantation procedures for impacted maxillary canines: A clinical report

Single tooth implant-supported restorations have become a common procedure for the restoration of missing teeth. This clinical report describes the treatment and long-term follow-up of 2 maxillary implant-supported crowns in the canine region placed after unsuccessful reimplantation and successful bone augmentation procedures. In spite of the complicated procedures presented, a good long-term clinical result was achieved.
