The Effect of Premolar Tooth Extraction on the Overall Bolton Ratio in Class I Malocclusion at the USU FKG RSGMP

Introduction

In orthodontic treatment, achieving a stable and harmonious occlusion is crucial for the overall health and well-being of the patient. One of the key factors in determining the success of orthodontic treatment is the Bolton ratio, which is a measure of the width of the mesiodistal width of the upper and lower jaw teeth. The Bolton ratio is an essential parameter in orthodontic diagnosis and treatment planning, as it helps to determine the balance between the width of the upper and lower jaw teeth. Premolar tooth extraction, although a common procedure in orthodontic treatment, has the potential to change the overall Bolton ratio, and this change is influenced by a combination of different extractions. This study aims to determine the effect of premolar tooth extraction on the overall Bolton ratio in class I malocclusion patients.

Methodology

This study involved 40 class I malocclusion study models, which were measured using digital calipers with an accuracy of 0.01mm. The overall Bolton ratio was determined before and after premolar tooth extraction. The subjects were divided into three groups based on the average value and standard deviation of Bolton: the Bolton group was small, normal, and large. Then, a simulation of revocation with four combinations was performed, namely:

First 4 Premolar Dear Evocation
Revocation of 4 second premolar teeth
Revocation of the first premolar of the upper jaw and the second jaw premolar
Revocation of the second jaw and the lower jaw's first jaw premolar

Data Analysis

Data analysis was performed using the Anova Oneway Test and the Wilcoxon Signed Rank test. The results showed that the overall Bolton ratio decreased after premolar tooth extraction in all combinations of extraction. The small Bolton group remained in the small category. The normal Bolton group changed, with some subjects entering the normal and small groups, while the large Bolton group almost entirely shifted into a normal Bolton value.

Conclusion

The four combinations of premolar extraction have a significant impact on the overall Bolton ratio. The overall Bolton ratio value is reduced after removal of all combinations of extraction.

Further Analysis

The Importance of Considering the Overall Bolton Ratio

This study shows that premolar tooth extraction significantly affects the overall Bolton ratio. This factor needs to be considered carefully by the dentist in planning orthodontic care. The Bolton ratio is a critical parameter in determining the success of orthodontic treatment, and any changes to this ratio can have significant implications for the patient's dental health.

Impact of Dental Harmony

Changes in the overall Bolton ratio can have an impact on dental harmony and occlusion. Dental harmony is essential for maintaining good oral health and preventing dental problems such as tooth wear, gum disease, and tooth loss. Therefore, it is crucial to consider the overall Bolton ratio when planning orthodontic treatment.

The Importance of Individual Evaluation

Although this research shows a general trend, each patient has a unique characteristic. Therefore, it is essential to evaluate each patient individually to determine the right treatment strategy. A one-size-fits-all approach to orthodontic treatment can lead to suboptimal results and may even cause harm to the patient.

Suggestion

Further research is needed to examine the long-term impact of premolar extraction on the overall Bolton ratio and dental harmony.
It is essential for dentists to understand the implications of changes in the overall Bolton ratio and to plan the right treatment strategy to minimize negative effects.

Limitations of the Study

This study has several limitations. Firstly, the sample size was relatively small, and further research is needed to confirm the findings of this study. Secondly, the study only examined the short-term effects of premolar extraction on the overall Bolton ratio, and further research is needed to examine the long-term impact of this procedure. Finally, the study only considered the Bolton ratio as a measure of dental harmony, and further research is needed to examine the impact of premolar extraction on other measures of dental harmony.

Conclusion

In conclusion, this study shows that premolar tooth extraction has a significant impact on the overall Bolton ratio in class I malocclusion patients. The Bolton ratio is a critical parameter in determining the success of orthodontic treatment, and any changes to this ratio can have significant implications for the patient's dental health. Therefore, it is essential to consider the overall Bolton ratio when planning orthodontic treatment, and individual evaluation is crucial to determine the right treatment strategy.

Recommendations

Based on the findings of this study, the following recommendations can be made:

Dentists should consider the overall Bolton ratio when planning orthodontic treatment.
Individual evaluation is essential to determine the right treatment strategy.
Further research is needed to examine the long-term impact of premolar extraction on the overall Bolton ratio and dental harmony.
Dentists should understand the implications of changes in the overall Bolton ratio and plan the right treatment strategy to minimize negative effects.

Future Research Directions

Future research should focus on examining the long-term impact of premolar extraction on the overall Bolton ratio and dental harmony. Additionally, further research is needed to examine the impact of premolar extraction on other measures of dental harmony, such as the Bolton ratio, the overjet, and the overbite. Finally, further research is needed to examine the impact of premolar extraction on the patient's quality of life and overall well-being.
Frequently Asked Questions (FAQs) about the Effect of Premolar Tooth Extraction on the Overall Bolton Ratio in Class I Malocclusion

Q: What is the Bolton ratio, and why is it important in orthodontic treatment?

A: The Bolton ratio is a measure of the width of the mesiodistal width of the upper and lower jaw teeth. It is an essential parameter in orthodontic diagnosis and treatment planning, as it helps to determine the balance between the width of the upper and lower jaw teeth. A good Bolton ratio is crucial for achieving a stable and harmonious occlusion.

Q: What is the effect of premolar tooth extraction on the overall Bolton ratio?

A: Premolar tooth extraction can significantly affect the overall Bolton ratio. The Bolton ratio decreases after premolar tooth extraction in all combinations of extraction. This change can have significant implications for the patient's dental health and overall well-being.

Q: What are the different combinations of premolar extraction, and how do they affect the overall Bolton ratio?

A: The four combinations of premolar extraction used in this study were:

First 4 Premolar Dear Evocation
Revocation of 4 second premolar teeth
Revocation of the first premolar of the upper jaw and the second jaw premolar
Revocation of the second jaw and the lower jaw's first jaw premolar

Each combination of extraction resulted in a decrease in the overall Bolton ratio.

Q: What are the implications of changes in the overall Bolton ratio for the patient's dental health?

A: Changes in the overall Bolton ratio can have significant implications for the patient's dental health. A decrease in the Bolton ratio can lead to dental problems such as tooth wear, gum disease, and tooth loss. Therefore, it is essential to consider the overall Bolton ratio when planning orthodontic treatment.
