The Effect of Anterior Retraction on the Thickness of the Alveolar Bone Labial Teeth of the Maxillary Incisors

Introduction

Anterior dental retraction is a common treatment method used to correct Skeletal Class II Malocclusion, particularly in patients who have reached the final stage of growth. This procedure involves premolar tooth extraction to improve teeth irregularity, followed by anterior dental retraction to reduce overjet. However, the effects of this process on the alveolar bone and anterior tooth roots are not well understood. This study aims to assess changes in alveolar bone thickness after anterior retraction treatment and explore the relationship between these changes and the amount of incisors.

Background

Anterior dental retraction is a complex process that involves the movement of teeth and the surrounding bone. The alveolar bone, which supports the teeth, is a dynamic structure that can change in thickness and density in response to orthodontic treatment. Understanding the effects of anterior retraction on the alveolar bone is crucial for the development of effective and safe orthodontic treatment plans.

Methodology

This study used a cross-sectional study design to analyze changes in alveolar bone thickness in linear and angular direction after anterior retraction treatment. Digital cephalometry radiography was used to measure the alveolar bone thickness in 43 lateral cephalometric photos, both before and after treatment. The results showed differences in alveolar bone thickness at the 9 mm level of cementoenamel junction (CEJ) in linear direction, with a value of P <0.05, indicating statistical significance.

Results

The results of this study revealed that there was no difference in alveolar bone thickness at levels 3 and 6 mm from CEJs, both in linear and angular direction (P> 0.05). This suggests that the influence of anterior retraction is uneven in all areas of the alveolar bone, and only detected at deeper levels. Furthermore, the results showed that changes in alveolar bone thickness did not have a significant relationship with the number of incision retractions carried out (P> 0.05).

Discussion

The findings of this study have important implications for the development of effective and safe orthodontic treatment plans. The uneven influence of anterior retraction on the alveolar bone suggests that orthodontic treatment, especially those involving anterior retraction, needs to be done with more attention to alveolar bone health. Limitations of teeth movement and its impact on bone structure must be calculated to prevent unwanted effects.

Conclusion

This study highlights the importance of considering the effects of anterior retraction on the alveolar bone in orthodontic treatment planning. The results of this study should be taken into account by dentists and orthodontists when making clinical decisions, to ensure that treatment is not only effective in terms of aesthetic but also safe for the health of the patient's dental bones. Further research is needed to better understand the mechanisms involved in changes in alveolar bone thickness and how other factors, such as age and dental health conditions, can affect the final treatment.

Recommendations

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

Orthodontic treatment, especially those involving anterior retraction, should be done with more attention to alveolar bone health.
Limitations of teeth movement and its impact on bone structure must be calculated to prevent unwanted effects.
Further research is needed to better understand the mechanisms involved in changes in alveolar bone thickness and how other factors, such as age and dental health conditions, can affect the final treatment.

Limitations

This study has several limitations, including:

The sample size was relatively small, which may limit the generalizability of the findings.
The study only measured alveolar bone thickness at specific levels, which may not be representative of the entire alveolar bone.
The study did not control for other factors that may affect alveolar bone thickness, such as age and dental health conditions.

Future Directions

Further research is needed to better understand the mechanisms involved in changes in alveolar bone thickness and how other factors, such as age and dental health conditions, can affect the final treatment. This may involve:

Conducting larger-scale studies to confirm the findings of this study.
Measuring alveolar bone thickness at multiple levels to get a more comprehensive understanding of the effects of anterior retraction.
Controlling for other factors that may affect alveolar bone thickness, such as age and dental health conditions.

Conclusion

In conclusion, this study highlights the importance of considering the effects of anterior retraction on the alveolar bone in orthodontic treatment planning. The results of this study should be taken into account by dentists and orthodontists when making clinical decisions, to ensure that treatment is not only effective in terms of aesthetic but also safe for the health of the patient's dental bones. Further research is needed to better understand the mechanisms involved in changes in alveolar bone thickness and how other factors, such as age and dental health conditions, can affect the final treatment.
