A well-aligned maxillary midline with the facial midline is a prevalent characteristic of aesthetically pleasing smiles in Caucasian populations. This classic design research insight is drawn from a 2020 study published in BMC Oral Health. Using Observational study with 140 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize symmetry and alignment with the facial midline in designs that are intended to be aesthetically pleasing when viewed on or interacting with the face.

Key Findings
- 0194.3% of participants had a maxillary interincisal midline that coincided with the facial midline.
- 0280% of participants exhibited a consonant smile line.
- 03The upper lip curve was upward in 47.1% of cases, followed by a straight curve in 41.4%.
- 0484.3% of subjects had a medium smile line with tooth exposure up to the second premolar.
- 05No significant gender differences were found for the studied parameters.
Application
Design takeaway
Prioritize symmetry and alignment with the facial midline in designs that are intended to be aesthetically pleasing when viewed on or interacting with the face.
How to apply
When designing products like virtual reality headsets, face masks, or even graphical user interfaces that are positioned relative to the user's face, ensure that key visual elements align with the natural facial midline for optimal aesthetic appeal.
Project actions
- 01When documenting your design process, consider how your product's visual elements align with human facial features.
- 02If your design involves user interaction with their face, research anthropometric data relevant to facial proportions.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Prospective study design.
- +Adequate sample size for statistical analysis.
Limitations
This study's findings are specific to Caucasian individuals and may not apply universally. The subjective nature of aesthetics can also be a limitation.
Reliability & validity
The study used statistical tests (chi-squared) to analyze data, and a defined confidence level (95%) and significance level (5%), contributing to its statistical validity. Reliability would depend on consistent measurement techniques by the researchers.
Think critically
How might cultural differences influence the perception of ideal facial midline alignment and other smile aesthetics, and how would this impact product design for a global market?
Design Principles
"Symmetry and midline alignment contribute to perceived aesthetic harmony."
Understanding established aesthetic norms, like midline alignment, is crucial for designers creating products or interfaces that interact with the human face, such as virtual reality headsets, eyewear, or even user interfaces on mobile devices. Adhering to these principles can enhance user comfort, perceived beauty, and overall product acceptance.
What This Means for Your Design
Most people's smiles look best when their front teeth are centered with their face. This is a good rule to follow when designing things that go on or near a person's face.
How to use in your project

Paragraph starter
Research indicates that a strong aesthetic preference exists for designs that exhibit symmetry and alignment with natural human proportions. Specifically, a study on smile aesthetics found that over 94% of participants had their maxillary midline aligned with their facial midline, suggesting that symmetry and central alignment are critical factors in perceived facial harmony. This principle can be applied to product design, particularly for items worn on or interacting with the face, to enhance user acceptance and aesthetic appeal.
