A 1-year retention period using Hawley retainers significantly reduces orthodontic relapse compared to a 6-month period. Longer retention improves long-term maxillary incisor alignment and stability.

Area of Science:

  • Orthodontics
  • Dental Biomaterials

Background:

  • Post-treatment orthodontic relapse is a common concern.
  • Maxillary retention strategies vary, impacting long-term stability.

Purpose of the Study:

  • To compare the efficacy of two different maxillary retention durations on posttreatment relapse.
  • To evaluate the impact of Hawley retainer wear schedules on incisor stability.

Main Methods:

  • A comparative study involving 38 orthodontic patients divided into two groups.
  • Group 1: 6-month retention (3 months full-time, 3 months nights-only).
  • Group 2: 12-month retention (6 months full-time, 6 months nights-only).

Main Results:

  • Group 2 (1-year retention) showed significantly less relapse (23%) compared to Group 1 (6-month retention) (50%) three months after retention cessation.

  • Mean relapse was 0.23 mm in Group 2 versus 0.77 mm in Group 1.
  • Only one patient in Group 2 experienced >3 mm relapse, versus seven in Group 1.

    • Conclusions:

    • A 1-year maxillary retention period is clinically superior to a 6-month period for maintaining orthodontic treatment outcomes.
    • Extended retention duration significantly reduces the risk and severity of incisor relapse.
