Mandibular Growth Patterns Influence Facial Aesthetics in Adolescents with Distal Bites

Adolescents with distal bites exhibit distinct facial aesthetic characteristics that are directly influenced by their specific patterns of mandibular growth.

Wiadomości Lekarskie · 2023

Key Findings

01Vertical and neutral-vertical mandibular growth is associated with narrow (leptoprosopic) faces.
02Neutral, horizontal, and neutral-horizontal growth patterns are linked to medium (mesoprosopic) and wide (europrosopic) faces.
03All adolescents with distal bites, regardless of mandibular growth type, present with a shorter lower facial third.
04The most significant aesthetic changes are observed in individuals with a predominantly horizontal mandibular growth pattern.

Application

Design takeaway

How to apply

When designing products that are worn on or interact with the face, consider creating adjustable features or offering variations that accommodate different facial proportions, especially if the target demographic is known to have specific skeletal characteristics.

Project actions

01When analyzing user data, look for correlations between physical characteristics and user preferences or performance.
02Consider how underlying biological or physical factors might influence user interaction with a designed product.

Method & Evidence

AimTo investigate how different types of mandibular growth affect the facial aesthetics of adolescents aged 10-13 years who have a distal bite.

MethodPhotostatic image analysis and morphological index calculation.

ProcedureResearchers analyzed photostatic images of 74 adolescents (aged 10-13) with distal bites, categorizing them by mandibular growth type. They calculated facial indices such as gl-me: zy-zy (face width), Izar facial-morphological index, facial tapered angle (FTA), gl-sn:sn-me (ratio of middle to lower face), and transverse indices (p-p:zy-zy, p-p:go-go) to assess facial shape and proportions.

Sample74 participants

ContextOrthodontics and facial morphology research.

Variables

IVType of mandibular growth

DVFacial aesthetic parameters (e.g., face shape indices, proportions)

CVAge (10-13 years), presence of distal bite

Strengths & Limitations

Strengths

+Investigated a specific demographic and condition, providing targeted insights.
+Utilized quantitative methods (index calculations) for objective analysis.

Limitations

The specific indices used in this study might not be universally applicable or easily measured without specialized tools. The aesthetic perception is subjective and can be influenced by cultural factors not explored here.

Reliability & validity

The use of established photostatic image analysis methods and morphological indices suggests good validity for measuring facial proportions. Reliability would depend on consistent image acquisition and measurement techniques.

Think critically

How might cultural perceptions of beauty interact with or override the influence of underlying skeletal structures on facial aesthetics?

Design Principles

"Facial aesthetics are a complex interplay of skeletal structure, soft tissue, and growth patterns; design solutions should account for this variability."

Understanding these correlations is crucial for designers involved in creating products or interventions that interact with the face, such as medical devices, protective gear, or even digital avatars. It allows for more tailored and aesthetically sensitive design solutions.

What This Means for Your Design

This study shows that how a teenager's jaw grows affects what their face looks like, especially if they have a certain type of bite. People with a distal bite tend to have a shorter lower face, and the way the jaw grows horizontally causes the biggest changes.

How to use in your project

1.Use this research to justify design choices related to facial anthropometry or aesthetic considerations in your design project.
2.Cite this study when discussing how user physiology impacts design requirements.

Paragraph starter

Research indicates that specific physiological characteristics, such as mandibular growth patterns, significantly influence facial aesthetics in adolescents with distal bites. This suggests that design interventions targeting the face should account for such underlying anatomical variations to ensure appropriate aesthetic outcomes and user acceptance.
