Abstract:
BACKGROUND AND OBJECTIVES: Unwanted post treatment tooth movements are known as relapse. To counter such relapse, the employment of bonded retainers to the mandibular or maxillary incisors has become an established part of Orthodontic practice. Therefore, the purpose of this in- vitro study was to investigate the shear bond strength offered by the various combinations of lingual retainer wires and composite and the Yield strength (Y), Ultimate tensile strength (UTS) andw4 Modulus of Elasticity (E) retainer wires used. MATERIALS AND METHOD: The materials used for the study included different orthodontic retainer wires and composite. The orthodontic retainer wires used was Ortho Flextech - Stainless Steel(Group 1), OrthoClassic Dead Soft Retention Wire(Group 2), and custom made twised wire (0.010” Stainless Steel Ligature)(Group 3). Composite that was used Transbond Lingual Retainer (3M Unitek,).The light cure unit used was from Elipar-3M ESPE. 90 human incisors with no visible enamel defects were used. Retainer wires were bonded on the lingual surfaces of the teeth. 45 samples were divided into 3 groups, which were subjected to debonding with a chisel head in UTM. Each retainer wire was tested for the flexural properties through tensile testing. Comparisons of the means of SBS values and flexural properties values were made with one way ANOVA & Post Hoc Tukey’s. RESULT: The SBS values of the three groups indicated statistically significant difference (P< 0.05) in which bond strength (MPa) is highest in the Group 2 followed by Group 1 and Group 3. In flexural properties custom made twised wire (0.010” Stainless Steel Ligature) was highest CONCLUSION: The present study concluded that although there is significant difference in the mechanical properties of the different lingual retainer wires, they are still suitable for clinical use.
