Fracture Resistance of Reattached Teeth: In Vitro Evaluation of Various Reattachment Techniques
Year: 2024
Type: article
Abstract: Aims and background: Fragment reattachment remains a preferred conservative treatment, offering a balance between esthetic recovery, patient satisfaction, and functionality.Understanding the reattachment technique options helps clinicians provide the best care tailored to individual cases.Materials and methods: Thirty permanent maxillary central incisors were mounted in acrylic resin and divided into 3 groups (n = 10) based on reattachment methods: Group A (Control), group B (Chamfer), group C (Overcontouring).Standardized crown fractures were simulated and reattached using a light-curable flow able composite.The specimens were stored, thermocycled, and tested for fracture resistance.Results: Intact teeth (Control) showed the highest fracture resistance (372 ± 17.45 N).Among reattached teeth, overcontouring (295.9 ± 24.00 N) performed best, followed by Chamfer (170.2 ± 28.39 N).Conclusion: None of the reattachment techniques matched the fracture resistance of intact teeth.Overcontouring yielded the best results, while the Chamfer technique is not recommended due to its low fracture resistance.Clinical significance: By understanding the strengths and limitations of various reattachment techniques, clinicians can make informed decisions to optimize both functional and esthetic outcomes for patients with anterior tooth fractures.
