Shear Bond Strength in Stainless Steel AISI 316L Reconditioned Brackets (In Vitro)

Introduction

Stainless Steel (SS) brackets are one of the most commonly used types of brackets in orthodontic treatment. However, a significant problem faced by clinicians is the release of brackets during the treatment process. To overcome this issue, clinicians often choose to recondition the released bracket through heating and reinstallation. This method is taken to reduce the costs borne by the patient. The aim of this study is to assess the value of Shear Bond Strength (SBS) in new SS brackets and SS brackets that have been reconditioned once and twice.

Background

Orthodontic treatment is a complex process that requires careful planning and execution. The success of orthodontic treatment depends on various factors, including the type of bracket used, the bonding material, and the bonding technique. One of the critical factors that affect the success of orthodontic treatment is the shear bond strength (SBS) between the bracket and the tooth. SBS is the force required to break the bond between the bracket and the tooth. A higher SBS value indicates a stronger bond, which is essential for the stability of the treatment.

Methodology

In this study, a total of 27 sets of upper jaw premolar teeth were used, where each set of teeth was equipped with an SS bracket attached using an adhesive material. The sample grouping consisted of 9 new SS brackets (as control), 9 SS brackets that had been reconditioned once, and 9 SS brackets that had been reconditioned twice. Before the SBS testing was carried out, the entire sample was immersed in aquadestilation at 37°C for 24 hours. SBS testing was carried out using a Universal Testing Machine (UTM) device with a crosshead speed of 0.5 mm/minute.

Results

The test results show that the new SS bracket (control) has the highest SBS average value, which is 9.95 ± 4.35 MPa, followed by SS brackets that had been reconditioned once with a value of 7.35 ± 2.40 MPa, and finally, the SS brackets that had been reconditioned twice with a value of 6.87 ± 3.23 MPa. Although there are differences in the SBS value between groups, statistically, these differences are not significant.

Discussion

The results of this study indicate that the SS brackets that had been reconditioned, both once and twice, still have an acceptable SBS value to ensure success in orthodontic care. This shows that reconditioning brackets through heating is a valid and economical alternative and does not reduce the effectiveness of the bracket during treatment. The understanding of shear bond strength is very important in the practice of orthodontics because the strength of the bond between brackets and teeth directly affects the stability of the treatment. Thus, the decision to recondition brackets can be a good step, especially in the context of saving maintenance costs.

Conclusion

In conclusion, this study has demonstrated that reconditioning SS brackets through heating is a valid and economical alternative that does not reduce the effectiveness of the bracket during treatment. The results of this study have also shown that the SBS value of reconditioned brackets is still acceptable, indicating that reconditioning is a viable option for clinicians. Further research can be carried out to explore various other reconditioned methods that might increase the value of SBS, as well as the long-term influence on the success of orthodontic care.

Recommendations

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

  1. Further research: Further research can be carried out to explore various other reconditioned methods that might increase the value of SBS, as well as the long-term influence on the success of orthodontic care.
  2. Development of new reconditioning methods: New reconditioning methods can be developed to improve the SBS value of reconditioned brackets.
  3. Clinical trials: Clinical trials can be conducted to evaluate the effectiveness of reconditioned brackets in orthodontic treatment.
  4. Education and training: Clinicians should be educated and trained on the proper use of reconditioned brackets and the importance of SBS in orthodontic treatment.

Limitations

This study has several limitations, including:

  1. Small sample size: The sample size of this study was small, which may limit the generalizability of the findings.
  2. Limited reconditioning methods: This study only evaluated two reconditioning methods, and further research is needed to explore other methods.
  3. Short-term evaluation: This study only evaluated the SBS value of reconditioned brackets in the short-term, and further research is needed to evaluate the long-term influence on the success of orthodontic care.

Future Directions

Future research can be carried out to explore various other reconditioned methods that might increase the value of SBS, as well as the long-term influence on the success of orthodontic care. Additionally, new reconditioning methods can be developed to improve the SBS value of reconditioned brackets. Clinical trials can be conducted to evaluate the effectiveness of reconditioned brackets in orthodontic treatment. Clinicians should be educated and trained on the proper use of reconditioned brackets and the importance of SBS in orthodontic treatment.
Frequently Asked Questions (FAQs) about Shear Bond Strength in Stainless Steel AISI 316L Reconditioned Brackets (In Vitro)

Q: What is Shear Bond Strength (SBS)?

A: Shear Bond Strength (SBS) is the force required to break the bond between a bracket and a tooth. It is an essential factor in the success of orthodontic treatment, as a higher SBS value indicates a stronger bond.
