This study found that bonded space maintainers are effective for preserving space after primary molar extraction in children. The appliances showed a low failure rate and maintained space without significant changes.

Area of Science:

  • Pediatric Dentistry
  • Orthodontics
  • Biomaterials

Background:

  • Space maintainers are crucial for preserving arch length after premature loss of primary teeth.
  • Traditional space maintainers can be time-consuming and costly to fabricate and fit.
  • Bonded space maintainers offer a potentially more efficient chair-side solution.

Purpose of the Study:

  • To clinically evaluate the efficacy and durability of a novel bonded space maintainer.
  • To assess the reduction in chair-side time and cost associated with bonded space maintainers.
  • To determine the impact of bonded space maintainers on the maintained space over a 6-month period.

Main Methods:

  • Sixty bonded space maintainers were fabricated using 0.7 mm stainless steel round wire and light-cured composite.

  • Appliances were bonded to adjacent teeth following posterior primary molar extraction in 36 children (ages 5-9).
  • Space measurements were taken from study models before and after 6 months of appliance wear.

    • Main Results:

    • A low failure rate of 8.3% was observed, primarily due to occlusal or facial trauma.
    • No statistically significant alterations in the maintained space dimensions were detected using the Student t-test.
    • The bonded appliance design proved clinically manageable for space maintenance.

    Conclusions:

    • Bonded space maintainers represent a viable and efficient alternative to traditional appliances.
    • These appliances demonstrate good clinical performance with minimal failure rates.
    • Further research could explore long-term efficacy and patient comfort.
