简要总结

The goal of this study is to evaluate whether a new 3D-printed dental device can effectively maintain space after premature loss of primary teeth in children, compared to the traditional stainless-steel device. It will also assess safety and comfort. The main questions it aims to answer are:

  1. What is the clinical success rate of 3D printed space maintainers compared to traditional metal band and loop space maintainers over a 12-month period?
  2. How do 3D printed space maintainers compare in maintaining space and preventing rotation of abutment teeth?
  3. What are the differences in gingival health outcomes between the two types of space maintainers?

Participants (13 children aged 6-9 years) will:

Receive both devices in a "split-mouth" design (one on each side of the mouth), totaling 26 treated tooth spaces (13 per group).

Attend checkups every 3 months for a year to monitor the devices' performance.

结局指标

主要结局

Clinical Success Rate of Space Maintainers

时间窗: 12 months

Percentage of space maintainers remaining functional without failure Unit of Measure: Percentage of participants

Gingival health index

时间窗: at 3-month follow-up, 6 months follow-up , and 1 year follow-up

measuring Gingival index for both space maintainers to compare the a ability of plaque to attach to both devices. scale 0-3, higher scores indicate worse gingival health

次要结局

  • Wong-Baker FACES Pain Rating Scale(immediately after cementation,at 3-month follow-up)
