Enamel Analysis by 3D Scanning after Three Orthodontic Clean-Up Procedures: An In-Vitro Test of a New Piezoelectric...

Area of Science:

• Dental Materials Science
• Orthodontic Technology
• Biomaterials Engineering

Background:

• Orthodontic treatment often requires adhesive removal from enamel.
• Residual adhesive can compromise oral hygiene and aesthetics.
• New instruments are needed for efficient and safe post-orthodontic clean-up.

Purpose of the Study:

• To evaluate the clinical safety and efficacy of a novel piezoelectric instrument for orthodontic adhesive removal.
• To compare the performance of the piezoelectric instrument against conventional methods.

Main Methods:

• An in-vitro study utilized 75 extracted teeth, divided into three groups (n=25 each).
• Tested methods included a new piezoelectric instrument, a one-step finisher/polisher, and a tungsten carbide bur with discs.
• A 3D scanner assessed residual adhesive volume and enamel volume loss.

Main Results:

• The piezoelectric instrument demonstrated effective adhesive removal with minimal enamel loss.
• Compared to other methods, the tested instrument showed favorable results in reducing residual adhesive and preserving enamel.
• Statistical analysis indicated asymmetrical distribution of results between groups.

Conclusions:

• The novel piezoelectric instrument is a safe and effective option for post-orthodontic clean-up.
• Its ergonomic design and speed offer advantages for both patients and clinicians.
• This instrument is particularly relevant with the increasing popularity of invisible aligners.
