Facial Midline Alignment is Crucial for Aesthetic Smiles
A significant majority of young adults exhibit a lack of midline coincidence between their dental arch and facial features, impacting the perceived aesthetic of their smile.
International Journal of Dentistry · 2020
Key Findings
- 0159.3% of young adults lacked a coinciding dental and facial midline.
- 0253.2% of young adults had a nonparallel smile (incisal curve and lower lip line).
- 0362.5% of young adults had no visible buccal corridors.
- 04Gender differences were observed in smile parallelism and upper lip line position.
Application
Design takeaway
Incorporate principles of symmetry and alignment, akin to classic aesthetic ideals, into design to enhance visual harmony and user perception.
How to apply
When designing products with a visual component, such as consumer electronics, furniture, or digital interfaces, pay close attention to the alignment of elements and overall symmetry.
Project actions
- 01Consider how symmetry and alignment contribute to the perceived quality of a design.
- 02Explore classic design principles and how they are applied (or intentionally broken) in contemporary products.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Objective measurement using photographic analysis and software.
- +Inclusion of both male and female participants.
Limitations
The subjective nature of aesthetic judgment and the cultural specificity of beauty standards can be limitations.
Reliability & validity
The use of standardized photographic equipment and software for analysis contributes to reliability. Validity is supported by the focus on established aesthetic parameters in dentistry.
Think critically
To what extent are 'classic' aesthetic principles universally applicable across different cultures and demographics, and how might designers navigate these differences?
Design Principles
"Symmetry and alignment are foundational to aesthetic appeal."
Understanding established aesthetic principles, like facial midline alignment, is fundamental in design, especially in fields like product design or even user interface design where visual balance and harmony are key. Deviations from these principles can lead to a less pleasing or even jarring user experience.
What This Means for Your Design
Many young people's smiles aren't perfectly straight or aligned with their face, which can make them look less 'perfect' or 'classic'.

Paragraph starter
The study by Mohan et al. (2020) on dentogingival smile analysis reveals that a significant majority of young adults exhibit deviations from ideal midline alignment and smile parallelism. This underscores the importance of established aesthetic principles, such as symmetry and balance, which are often rooted in classic design canons, and their impact on perceived visual harmony.

- How strong is the evidence?
- Evidence strength is rated Strong effect, based on a 2020 journal from International Journal of Dentistry.
- What should I do differently in my next project?
- When designing products with a visual component, such as consumer electronics, furniture, or digital interfaces, pay close attention to the alignment of elements and overall symmetry.
- What are the limitations?
- The study focused on a specific demographic and geographic region, limiting generalizability. The assessment of aesthetics is subjective to some extent.
- Is there evidence that facial midline affects design outcomes?
- A substantial portion of young adults do not possess ideal smile aesthetics, particularly concerning the alignment of their dental midline with their facial midline and the parallelism of their smile. Understanding established aesthetic principles, like facial midline alignment, is fundamental in design, especially in Source: International Journal of Dentistry (2020).
