Deep Bite Correction with the Invisalign System: A Case-Series Study

Area of Science:

• Dentistry
• Orthodontics
• Biomedical Engineering

Background:

• Deep bite malocclusion affects dental and facial aesthetics.
• Clear aligner therapy offers a less invasive alternative to traditional braces.
• Understanding treatment-induced changes is crucial for effective orthodontic care.

Purpose of the Study:

• To assess dental and skeletal changes from Invisalign treatment for deep bites.
• To evaluate the efficacy of clear aligners in correcting deep bite malocclusion.

Main Methods:

• Retrospective case series of 37 adult deep bite patients.
• Analysis of pre- and post-treatment cephalograms.
• Statistical comparison of 19 dental and skeletal variables using Wilcoxon analysis.

Main Results:

• Significant changes in 14 of 19 variables (p < 0.05).
• Key findings include decreased overjet/overbite, posterior extrusion, anterior intrusion, and lower incisor proclination.
• Minimal skeletal alterations observed, with a slight increase in the sella-nasion-mandibular plane angle.

Conclusions:

• Invisalign is effective for correcting dental deep bites via posterior extrusion and anterior intrusion.
• Clear aligner therapy results in minimal skeletal changes for deep bite correction.
• This study provides insights into expected dental and skeletal outcomes of Invisalign deep bite treatment.
