The recementation of orthodontic bands using different cements

Area of Science:

• Orthodontics
• Dental Materials Science

Background:

• Orthodontic bands are crucial for dental alignment.
• Band failure can disrupt treatment and increase costs.
• Optimizing cementation protocols is essential for successful orthodontic outcomes.

Purpose of the Study:

• To evaluate and compare the clinical failure rates of orthodontic bands cemented with different materials.
• To identify factors influencing band failure in orthodontic practices.

Main Methods:

• A clinical study involving 5949 bands cemented on 293 patients across three orthodontic practices.
• Bands were cemented using Durelon cement, oxyphosphate cements, and an experimental polycarboxylate cement.
• Failure rates were recorded and compared between different cement types and practices.

Main Results:

• Overall band failure rates varied significantly, from 7% with Durelon cement to 19% with oxyphosphate cements.
• Durelon cement demonstrated a lower failure rate than an experimental polycarboxylate cement in controlled prospective studies.
• Maxillary central incisors exhibited the highest frequency of band failure.
• Practices using oxyphosphate cements or different procedures showed higher failure rates compared to those using Durelon.

Conclusions:

• Durelon cement is associated with a lower orthodontic band failure rate compared to oxyphosphate cements.
• Variations in band types, cements, and operator techniques may contribute to differing failure rates across practices.
• Further research into optimal cement selection and application is warranted to minimize band failures.
