Manual Digital Smile Designs Outperform AI in Aesthetic Appeal

Human-crafted digital smile designs are currently perceived as more aesthetically pleasing than AI-generated designs across various user groups.

BDJ Open · 2025

01

Key Findings

  • 01Manually crafted smile designs were consistently preferred over AI-generated designs by all participant groups.
  • 02AI-generated smiles showed higher acceptance rates in specific clinical cases (Cases 3 and 4) compared to others.
  • 03No significant aesthetic preference differences were found based on participant demographics (sex, age, occupation).
02

Application

Design takeaway

Prioritize human aesthetic judgment and artistic skill in the design process, especially for applications where subjective beauty and emotional connection are paramount.

How to apply

When developing or utilizing AI-assisted design tools, ensure a robust human review and refinement stage to optimize aesthetic outcomes.

Project actions

  • 01When comparing design options, consider both objective performance and subjective user preference.
  • 02If using AI in your design process, clearly articulate how human input enhances the final output.
03

Method & Evidence

AimTo compare the aesthetic preferences for conventionally designed digital smiles versus AI-generated digital smiles among dental professionals and laypersons.
MethodCross-sectional questionnaire-based study
ProcedureParticipants evaluated paired digital smile designs (manually crafted vs. AI-generated) for four clinical cases and indicated their aesthetic preferences. Demographic data were also collected.

Strengths & Limitations

Strengths

  • +Inclusion of diverse participant groups (students, professionals, laypersons).
  • +Evaluation across multiple clinical scenarios.

Limitations

The study was specific to dental aesthetics and may not apply to all design fields. The AI used might not represent the most advanced current capabilities.

Reliability & validity

The study's validity is supported by a clear methodology and statistical analysis. Reliability could be enhanced by testing across a wider range of AI tools and design styles.

Think critically

To what extent will future AI advancements bridge the aesthetic gap, and what new criteria will define 'superior' design in an AI-augmented world?

05

Design Principles

"Human aesthetic intuition is currently superior to AI in achieving nuanced and personalized visual appeal."

This research highlights the enduring importance of human artistic judgment and nuanced understanding in design, even with the advent of advanced automation. For designers, it underscores that while AI can offer efficiency, the 'human touch' remains a critical differentiator for achieving superior aesthetic outcomes that resonate with users.

06

What This Means for Your Design

People still like human-made digital smiles more than computer-generated ones because they look more natural and beautiful.
