Removal of fixed appliances.

Area of Science:

• Dentistry
• Biomaterials
• Dental Materials

Background:

• The established technique for removing fixed orthodontic appliances involves debonding attachments and removing adhesive remnants with burs.
• This process frequently leads to enamel loss, compromising tooth surface integrity.
• Enamel alterations increase susceptibility to demineralization and dental caries.

Purpose of the Study:

• To evaluate alternative methods for removing adhesive remnants after debonding fixed appliances.
• To compare the efficacy and safety of non-bur techniques in preserving enamel structure.
• To identify methods that minimize iatrogenic damage to the tooth surface.

Main Methods:

• Review of existing literature on adhesive removal techniques post-orthodontic treatment.
• Analysis of proposed alternative methods including hand instruments, lasers, and abrasive pastes.
• Assessment of reported outcomes regarding enamel loss and surface changes.

Main Results:

• Tungsten carbide burs commonly result in significant enamel loss.
• Alternative methods such as hand instruments, lasers, and pumice/zirconium pastes show potential for reduced enamel abrasion.
• Surface changes from bur use can impair enamel's resistance to acid attacks.

Conclusions:

• Standard bur use for composite residue removal poses a risk of enamel loss and increased caries susceptibility.
• Exploring and adopting alternative debonding techniques is crucial for preserving enamel integrity.
• Minimizing iatrogenic enamel damage is essential for long-term dental health post-orthodontic treatment.
