The Effect of Vertical Dimensional Changes on Facial Harmony Value in Skeletal Class I Malocclusion

Introduction

The vertical dimension of the face is a crucial aspect that needs to be considered in orthodontic treatment to achieve an ideal face balance. Changes that occur in the vertical dimension can significantly affect aesthetics, where soft tissue profiles become a measure of the success of treatment. In this study, we will examine the effect of changes in the vertical dimension on the value of facial harmonization after orthodontic treatment, using Arnett and Bergmann analysis in the class I skeletal malocclusion.

Understanding Facial Harmony

Facial harmony is a critical aspect of orthodontic treatment, and it is essential to understand the factors that contribute to it. Facial harmony is a subjective measure that is influenced by various factors, including the position of teeth, facial contours, and interactions between other facial elements. In the context of class I skeletal malocclusion, facial harmony is often compromised due to the abnormal alignment of teeth and the facial structure.

The Importance of Vertical Dimensional Changes

Changes in the vertical dimension can have a significant impact on facial aesthetics. A vertical dimension that is too short or too long can lead to an unbalanced facial profile, which can affect the overall appearance of the face. In orthodontic treatment, the vertical dimension is often adjusted to achieve an ideal face balance. However, the impact of these changes on facial harmony is not well understood, and this study aims to investigate this relationship.

Research Purposes

The purpose of this study is to determine the impact of changes in vertical dimensions on facial harmonization values after orthodontic treatment, based on Arnett and Bergmann analysis in class I skeletal malocclusion. This study involves two groups of samples, namely extraction and non-extraction groups. The extraction group consists of patients who underwent extraction of the first premolar teeth, while the non-extraction group consists of patients who did not undergo extraction.

Materials and Methods

The research sample consists of a lateral cefalometry photo before and after the treatment of 60 adult patients, which are divided into two groups: extraction and non-extraction of the first premolar teeth. Measurements were made using image J version 1.52A in 2018. The statistical test was then applied to analyze the effect of changes in vertical dimensions on facial harmonization values after orthodontic treatment of class I skeletal malocclusion, by comparing the results between the two groups.

Results

Based on the results of the paired T test in two groups of samples, no significant differences were found in the impact of face vertical changes (MP-SN) on facial harmonization values, with overall p value > 0.05 in class I malocclusion. In addition, there was no significant difference between the two sample groups, with a total P value > 0.05.

Conclusion

Changes in the vertical dimensions of the face do not have a significant effect on the total value of facial harmonization, both in groups of extraction and non-extraction. This finding shows that, although vertical dimensions are an important factor in the face aesthetics, in the context of class I malocclusion, these changes do not directly affect the value of facial harmonization after orthodontic treatment.

Additional Analysis and Explanation

Further analysis shows that although changes in the vertical dimension can be an important consideration in orthodontic practices, the results of this study indicate that not all of these changes have a significant impact on facial aesthetics. This may be caused by the complexity of other factors that play a role in aesthetic assessment, such as the position of teeth, facial contours, and interactions between other facial elements.

In addition, the selection of appropriate maintenance methods, both extraction and non-extraction, must be fixed based on the needs of individual patients, not just consideration of vertical dimensions. In the future, further research can be done to explore how other factors, such as the influence of age, sex, or certain medical conditions, also contribute to facial harmonization in the context of orthodontic care.

Implications for Orthodontic Practice

The findings of this study have significant implications for orthodontic practice. Orthodontic practitioners need to consider a comprehensive approach in designing treatment plans, which not only focus on changes in vertical dimensions, but also the overall facial aesthetics and balance of the patient's facial features. This is important so that the treatment results not only look good on paper, but also provide satisfaction to the patient as a whole.

Limitations of the Study

This study has several limitations. The sample size is relatively small, and the study only focuses on class I skeletal malocclusion. Further research is needed to investigate the impact of vertical dimensional changes on facial harmony in other types of malocclusion.

Future Research Directions

Future research can be done to explore how other factors, such as the influence of age, sex, or certain medical conditions, also contribute to facial harmonization in the context of orthodontic care. Additionally, further research can be done to investigate the impact of vertical dimensional changes on facial harmony in other types of malocclusion.

Conclusion

In conclusion, this study found that changes in the vertical dimensions of the face do not have a significant effect on the total value of facial harmonization, both in groups of extraction and non-extraction. This finding has significant implications for orthodontic practice, and it highlights the importance of considering a comprehensive approach in designing treatment plans. Further research is needed to explore the impact of vertical dimensional changes on facial harmony in other types of malocclusion and to investigate the influence of other factors on facial harmonization in the context of orthodontic care.
Frequently Asked Questions (FAQs) about the Effect of Vertical Dimensional Changes on Facial Harmony Value in Skeletal Class I Malocclusion

Q: What is the significance of vertical dimensional changes in orthodontic treatment?

A: Vertical dimensional changes are crucial in orthodontic treatment as they can significantly affect aesthetics, where soft tissue profiles become a measure of the success of treatment. Changes in the vertical dimension can lead to an unbalanced facial profile, which can affect the overall appearance of the face.

Q: What is facial harmony, and how is it related to orthodontic treatment?

A: Facial harmony is a subjective measure that is influenced by various factors, including the position of teeth, facial contours, and interactions between other facial elements. In the context of class I skeletal malocclusion, facial harmony is often compromised due to the abnormal alignment of teeth and the facial structure.

Q: What are the implications of this study for orthodontic practice?

A: The findings of this study have significant implications for orthodontic practice.
