Effect of tetrabutylammonium dihydrogen trifluoride treatment on durability of resin–titanium bond strengths

Abstract

This study investigated the effect of titanium surface treatment with tetrabutylammonium dihydrogen trifluoride (TDTF) on the bond between the titanium and resins for dental applications. Commercially pure titanium (cpTi) specimens were air-abraded with alumina particles, surface-treated with an etchant containing TDTF (Monobond Etch & Prime; ETCH) for 10 s (ETCH10) or 30 s (ETCH30), rinsed with water, treated with a phosphoric monomer-based primer, and bonded to an indirect resin composite. Non-ETCH-treated specimens (no-ETCH) were prepared as a control. The shear bond strengths were determined before and after 100,000 thermocycles, and the means and standard deviations for eight specimens were calculated and statistically analyzed using a non-parametric Steel–Dwass test (α = 0.05). The ETCH10 and ETCH30 specimens exhibited the highest bond strengths, which were maintained for 100,000 thermocycles, while significantly lower values were obtained for no-ETCH specimens. In conclusion, the surface treatment with a TDTF-containing etchant considerably improved the durability of the resin–cpTi bond strength. Appropriate surface treatment of cpTi should be selected for achieving longer-lasting treatments and better clinical solutions for patients.

Influence of Different Conditioning Protocols on Bond Strength to Glass Ceramic

“…13 The combination of TDTF and silane has been introduced to the market as a clinically acceptable product for glass-ceramic reinforced bonding. 14 Thermal cycling and mechanical loading have been shown in laboratory experiments to predict clinical failures, although it appears that appropriate validation for individual materials is required. 24 In this study, we used microtensile bond strength test because it can concentrate on three-dimensional surfaces that are clinically relevant and has a high capability for discrimination than the ordinary macroshear bond test.…”

“…7 The combination of TDTF + silane has been marketed as a clinically acceptable product for strengthening the bonds of glass ceramics. 14 TDTF is also acidic and has some dangerous effects. Therefore, due to the potential danger to human tissue, care must be taken when handling and applying self-etching primers containing less than ten percent TDTF .…”

Surface characteristics of additively manufactured CoCr and Ti6Al4V dental alloys: The effects of carbon and gold thin film coatings, and alkali‐heat treatment

“…In other applications, such as metal frameworks, these alloys are veneered with resin‐based materials to meet aesthetic preferences. However, conventional bonding systems do not always provide adequate protection against issues, such as localized detachment of veneering materials from the metal frameworks, microleakages, or discolorations and staining at the interfaces (Kamada et al, 2023). As a result, extensive research has focused on physical, chemical, and biological surface modifications for CoCr and Ti6Al4V alloys, utilizing diverse methodologies with the goal of modifying morphology, roughness, crystalline phase, and wettability (Jambhulkar et al, 2023; Kunrath et al, 2021).…”
