ABSTRACT

A misaligned tooth can cause serious aesthetic and functional challenges. Customized springs are indeed a practical remedy for aligning such teeth. The skill to provide an ideal system of forces to reach the desired movement, as well as the management of potential side effects, is directly linked to a successful outcome. One such approach is shown in this case report.

The prevalence of impacted maxillary canines is 2%–3%. The position of the canine germ should be evaluated between 9 and 11 years of age group. In addition to the clinical examination, radiographic evaluation of the canine site will aid in gathering additional data such as the position of the canine, its relationship with the adjacent teeth, and any oral pathology associated with the site. It becomes imperative to have an early diagnosis of the ectopically positioned canine. Orthodontic considerations which include orthodontic traction for the malpositioned canine tooth along with surgical exposure assume significance, if the permanent canine is deviating from its normal eruption pathway trajectory within its specified timeline of erupting into the dental arch. The objective of reporting the following two cases is to analyze a successful 1-year follow-up outcome of an interdisciplinary, evidence-based approach in managing impacted canines in two female patients in their second decades of life.

This study aimed to report a case of skeletal Class I adult with anterior open and transposed upper canines with premolars and lower right canine transposed with lateral incisor, retained upper deciduous C, B, and lower right C. With congenital missing upper right lateral incisor, upper spacing arch, and lower mild crowding arch, a patient complains about her smile esthetic. The case was treated using temporary anchorage devices and three-dimensional retraction loops designed primarily for upper canine transposition with an accepted esthetic reshaping of lower canine using composite restoration. The missing lateral had been implanted with smile makeover using microesthetic post-orthodontic treatment. After 16 months of treatment, it was possible to see a significant improvement of the patient's facial profile, with overcorrection in overjet and preservation of the tissues and integrity of dental roots.

Introduction: The gonial angle plays to be one of the significant indicators for the diagnosis of growth pattern of orthodontic patients. It is a known fact that lateral cephalograms are commonly used for the measurement of gonial angle, but panoramic radiographs (PRs) can display both the gonial angles simultaneously and as accurately as lateral cephalograms. The aim of this study is to develop an equation for the prediction of the skeletal pattern of nongrowing participants from gonial angle values on PR.

Materials and Methods: PRs and lateral cephalograms of 75 orthodontic patients were selected. The gonial angle was measured on PR and Sella Nasion-mandibular plane (SN-MP) angle was measured on lateral cephalograms. The values obtained were analyzed using paired Pearson's correlation test and regression analysis was done.

Results: The relationship between the gonial angle measurements obtained from each radiograph was represented as, “SN-MP angle (Skeletal pattern) = −44.297 + 0.6318 × Gonial angle (PR) in the linear function.”

Conclusion: Hence, PR could be used to determine the gonial angle as accurately as a lateral cephalogram and a useful tool for examining the skeletal pattern of patients.
