Finishing effectiveness of different archwires using SmartClip™ self-ligating brackets: a clinical study

Area of Science:

• Orthodontics and Dentofacial Orthopedics
• Biomaterials in Dentistry

Background:

• Self-ligating brackets are increasingly used in orthodontic treatment.
• Archwire selection is crucial for effective finishing in orthodontics.

Purpose of the Study:

• To compare the finishing effectiveness of stainless steel (SS) archwires versus titanium molybdenum alloy (TMA) archwires in conjunction with self-ligating brackets.
• To evaluate changes in incisor inclination, irregularity index, interdental widths, arch length, and arch depth.

Main Methods:

• A prospective clinical trial involving 32 patients divided into two groups: SS archwires (n=21) and TMA archwires (n=12).
• Used .019 × .025" SS and TMA archwires with SmartClip™ self-ligating brackets.
• Assessed changes using lateral cephalometric radiographs and dental cast measurements from T1 (beginning) to T2 (end).

Main Results:

• No significant differences were observed in incisor proclination or arch length changes between the groups.
• Statistically significant differences favored the SS group for a greater decrease in irregularity index, increased maxillary arch depth, and wider interdental widths.
• These statistically significant differences were deemed clinically negligible.

Conclusions:

• Both SS and TMA archwires demonstrated good finishing effectiveness when used with self-ligating brackets.
• No clinically significant differences were found between SS and TMA archwires in this study.
• The choice between SS and TMA archwires may not critically impact clinical outcomes in self-ligating bracket systems.
