Summary
The self-etch Transbond Plus Self-Etching adhesive demonstrated superior bracket survival rates compared to the conventional Transbond XT adhesive over a six-month period in orthodontic patients.
Area of Science:
- Orthodontics
- Dental Materials Science
- Adhesive Dentistry
Background:
- Orthodontic bracket bonding relies on effective adhesives.
- Conventional etch-and-rinse adhesives require multiple steps.
- Self-etch adhesives offer a simplified bonding procedure.
Purpose of the Study:
- To compare the clinical performance of Transbond Plus Self-Etching (self-etch) with Transbond XT (etch-and-rinse) over six months.
- To evaluate bracket survival rates and failure modes between the two adhesive systems.
Main Methods:
- A total of 567 metallic brackets were bonded in 30 adolescent patients (12-18 years).
- Homologous teeth received either the self-etch or conventional adhesive.
- Bracket failures were classified, and survival rates were analyzed using Kaplan-Meier and log-rank tests.
Main Results:
- The self-etch adhesive exhibited a lower failure rate (7.4%) compared to the conventional adhesive (10.6%).
- The conventional system's failure rate was 0.43 times greater than the self-etch system.
- Higher bracket survival rates were observed with the self-etch adhesive (P < .05).
Conclusions:
- Transbond Plus Self-Etching adhesive is a safe and effective option for orthodontic bracket bonding.
- The self-etch system provides superior bracket survival rates compared to conventional etch-and-rinse adhesives.
- Clinical application of self-etch adhesives in orthodontics is supported by these findings.
