Evaluation of Monobond® Plus with SpeedCEM® Plus for Orthodontic Purposes
Objectives: The purpose of this study was to assess the efficacy of Monobond® Plus (Ivoclar Vivadent) in conjunction with SpeedCEM® Plus (Ivoclar Vivadent) as an acceptable orthodontic bonding resin in the application of orthodontic brackets to ceramic and zirconia materials.
Methods: To emulate porcelain crowns, IPS e.max® CAD rods (10mm x 10mm x 20mm) (Ivoclar Vivadent)) were created and for zirconia, Jensen XT rods (10mm x 10mm x 40mm) (Jensen Dental) were made. The control bonding agent is Assure PLUS® (Reliance Orthodontics), and the experimental is Monobond Plus. There were N=35 samples per group. For treatment 1, the surface was sandblasted, treated according to Table 1. For treatment 2, the surface was etched using IPS® Ceramic Etching Gel (5% HF) (Ivoclar Vivadent) for twenty seconds, washed, and treated according to Table 1. For treatment 3, the surfaces were sandblasted and light cured for 10 seconds, followed by treatment according to Table 1. For treatment 4, material was sandblasted, followed by treatment according to Table 1. All brackets were light cured for twenty seconds with radii Plus curing light (SDI Limited). Samples tested after 24 hours with an Instron® Universal Testing Machine (Norwood, Massachusetts) with 1K load cell and 1mm/min cross-head speed.
Results: Treatment 1 showed a statistically significant difference compared to Treatment 2 (p=0.038). Treatment 3 showed a statistically insignificant difference to Treatment 4 (p=0.715) (Table 2).
Conclusions: When zirconia is the substrate the bonding agents had similar bond strengths. On porcelain, a better bond was formed when Monobond Plus was used.
