Deep overbite reduction in adolescent patients treated with Invisalign: A retrospective analysis

Area of Science:

• Orthodontics
• Dental Technology

Background:

• Efficacy data for deep overbite correction using clear aligners in adolescents is limited.
• This study addresses the lack of evidence by investigating Invisalign treatment outcomes.

Purpose of the Study:

• To evaluate the effectiveness of Invisalign clear aligners in reducing deep overbite in adolescent patients.
• To determine factors influencing the predictability of overbite reduction.

Main Methods:

• Retrospective analysis of 102 adolescent patients (aged 10-17) treated with Invisalign for overbite reduction.
• Utilized ClinCheck digital records for predicted, pre-treatment, and post-treatment overbite measurements.
• Employed linear modeling and Bland-Altman plots to assess age, bite ramps, and G8 protocol effects.

Main Results:

• Adolescents achieved an average of 41.38% of the planned deep overbite reduction.
• No significant differences in overbite reduction predictability were found based on age groups (<14 vs. 14-17 years).
• The use of bite ramps or the G8 protocol did not influence the achieved overbite reduction.

Conclusions:

• Invisalign treatment resulted in less than 50% of the planned deep overbite correction in this adolescent cohort.
• Age, bite ramps, and the G8 protocol showed minimal impact on the efficacy of overbite reduction.
• Further research may be needed to optimize clear aligner protocols for deep overbite correction.
