Brief Summary

This study aims to investigate the relationship between facial type and relapse of dentition post-orthodontically during the retention phase. According to the retention theorem "teeth which have been moved through orthodontic treatment tend to naturally return to their original position. It is hypothesized that significant differences will exist in tooth movement patterns between horizontal and vertical growers, with horizontal growers exhibiting more pronounced tooth movement in the vertical plane particularly in the overbite as compared to the vertical growers . Furthermore, it is expected that facial type will influence the stability of orthodontic treatment outcomes, with long-faced individuals showing more relapse of mandibular incisor alignment and crowding. By exploring this relationship, this study aims to provide valuable insights into the factors influencing orthodontic treatment outcomes and stability. With long-faced individuals exhibiting more mandibular backward rotation and short-faced individuals showing forward rotation, which increases the risk of deep bite . Additionally, understanding these factors is crucial for orthodontists to predict and prevent potential relapse, ensuring optimal treatment results and long-term stability. Hence, the present trial will be undertaken to assess the changes and compare If there is any difference in tooth movement in 3-Dimensional superimposition in the dentition in horizontal and vertical growers post orthodontically over a period of retention phase.

Conditions

Retention; Relapse

Outcome Measures

Primary Outcomes (1)

• To compare 3 dimensional dentitional changes in dentition in 3 planes of space

  To compare 3 dimensional dentitional changes in dentition in 3 planes of space using superimposition software • Antero-posterior plane (Y-axis) • Vertical plane (Z-axis) • Transverse plane (X-axis) at, T0(at the time of retainer delivery), T1(1 month of retainer delivery), T2(3 months of retainer delivery) and T3 (6 months of retainer delivery) ,T4 (12 months of retainer delivery) time interval.

  12 months

Study Arms (2)

vertical grower

OTHER

Patients belonging to group 1 will be patient with vertical growth pattern who have undergone fixed orthodontic cases and are ready for debonding with FMA of 26 0 or more. Begg's Retainer will be formed by conventional method and delivered within 24 hours of debonding. To compare 3 dimensional dentitional changes post orthodontically treated patients with vertical growth pattern over a 12 month retention period.

Other: 3 planes of space

Horizontal grower

OTHER

Patients belonging to group 2 will be patient with horizontal growth pattern who have undergone Fixed orthodontic cases and are ready for debonding with with FMA Of 24 o or less. Begg's Retainer will be formed by conventional method and delivered within 24 hours of debonding. To compare 3 dimensional dentitional changes post orthodontically treated patients with horizontal growth pattern over a 12 month retention period.

Other: 3 planes of space

Interventions
