Summary
This study compared the shear bond strength (SBS) of Admira and Transbond XT orthodontic adhesives. No significant difference was found, suggesting Ormocer materials may offer biocompatible alternatives for bracket bonding.
Area of Science:
- Orthodontics
- Dental Materials Science
- Biocompatibility
Background:
- Advancements in dental adhesives and bonding techniques have led to innovations in orthodontic materials.
- Orthodontic treatment relies on effective bracket bonding, necessitating evaluation of new adhesive systems.
Purpose of the Study:
- To compare the shear bond strength (SBS) of an organically modified ceramic matrix adhesive (Admira) with a traditional Bis GMA matrix adhesive (Transbond XT).
- To assess the potential of new, more biocompatible materials with lower wear rates for orthodontic applications.
Main Methods:
- Forty molar teeth were randomly assigned to two groups: 20 bonded with Admira and 20 with Transbond XT.
- Shear bond strength (SBS) was measured for both adhesive systems.
- Student's t-test was used for statistical comparison with significance set at P < or = .05.
Main Results:
- The mean SBS for Admira was 5.1 +/- 3.3 MPa, and for Transbond XT was 4.6 +/- 3.2 MPa.
- Statistical analysis (t = 0.489) showed no significant difference in SBS between the two adhesives (P = .628).
Conclusions:
- Organically Modified Ceramics (Ormocer) show potential for orthodontic applications due to their biocompatibility and low wear rate.
- Admira and Transbond XT demonstrated comparable shear bond strength in this study.
- Further development, such as improved flowability, may enhance Ormocer suitability for clinical orthodontic use.
