“…This high adhesion to dental enamel and less solubility in water makes resin adhesives more popularly used than acid-based cements. However, their intimate attachment, either used as the luting or bonding agent for dental prostheses or intraorally repairing restorations, respectively, mostly fail in adhesion with much less tensile bond strength (TBS) than that of tooth structure [ 12 , 13 , 14 , 15 , 16 ], which can lead to the high failure rates or short-term failure from prosthesis detachment [ 3 ]. Because of the low tensile bond strength between resin adhesive and prosthesis, more inner surface area for bonding is needed to provide the prosthesis retention against the masticatory load.…”

“…Airborne-particle abrasion with 50 µm aluminum oxide, hydrofluoric acid etching, or chemical primer application are routinely used on the prosthesis surface to improve the bond strength to resin adhesives [ 13 , 15 , 16 , 17 , 18 ]. Hydrofluoric acid, a common conditioner to decompose glass ceramics to increase surface roughness and area for higher retention of cemented prosthesis or intraoral ceramic repairing with resin composite, can injure soft tissues after exposure.…”

Although dental prosthesis materials such as metal alloys, ceramics, and cured resin composite have long been utilized to restore teeth, their bond strength and hardness values are not well matched to human enamel. Prosthesis detachment and opposing enamel wear are major concerns in restorative dentistry. An experimental biopolymer, hybridized enamel, was synthesized and utilized as a dental prosthesis to compare hardness and tensile bond strength (TBS) with those of commercial materials. Vickers hardness (VHN) with a 100 g loading for 15 s at eight indentations on each specimen (n = 20) was measured. TBSs between prostheses and two types of resin luting agents (n = 10), Super-Bond C&B and All-Bond2 + Duo-Link, were tested. Fractured surfaces and the luting resin-prosthesis interface were examined under a stereomicroscope or a scanning electron microscope (SEM). Statistically significant differences in the TBS and hardness were revealed (p < 0.05). The experimental biopolymer provided a hardness value comparable with human enamel and the highest TBS for both luting agent types. The SEM micrograph demonstrated a honeycomb-like pattern interface between the experimental biopolymer and luting resin. These results suggest that this experimental biopolymer may be a better restorative material to protect from natural enamel loss from tooth reduction or attrition and prevent prosthesis detachment during mastication.

Background:Resin-bonded fixed partial dentures appeared to prevent the excessive preparation of dental tissue. Investigation of surface treatments to improve the bond of resin cements to metals may contribute to the longevity of these restorations. Due to the potential lack of ideal preparation form, the type of alloy and its surface pretreatment may have clinically relevant correlations with the retentive strength of castings to minimally retentive preparations.Aim:The aim of this search is to study the bonding resin cement strength to different types of the metal alloy due to the surface treatment.Purpose:Evaluate the effects of two different surface treatments on shear bond strength (SBS) between a palladium-silver alloy (Pb-Ag) and commercially pure titanium (CP Ti) cast alloy with resin luting cements.Materials and Methods:A total of 120 cylinders having 5 mm in diameter and 4 mm in height were divided into two different main groups of metal type: 60 cylinders cast from CP Ti Grade I (Tritan - Reintitan - Germany-Dentaurum) as a base metal and 60 cylinders cast from Pb-Ag (Status-Yamakin, Japan) as a noble metal. 30 cylinders from each type were embedded in acrylic resin, and the rest were left without embedded in acrylic resin. All of the cylinders were smoothed with silicon carbide papers and sandblasting with 50-μm aluminum oxide. Specimens of each metal type were divided into two subgroups, which received one of the following luting techniques: (1) Multilink (Ivoclar Vivadent), (2) Multilink (Ivoclar Vivadent) plus metal zirconia primer (MZP). Every two cylinders from the same metal type and surface treatment were bonded to each other. All specimens were stored in distilled water at 37°C for 24 h and then thermal cycled (500 cycles, 5–55°C). After thermal cycling, the specimens were stored in 37°C distilled water for an additional 24 h before being tested in shear strength. Data (MPa) were analyzed using T-s tests to study the significance of various - means among groups and perform a comparison between each two groups of them.Results:The T-s tests indicated significant effect of combination of the sandblasting technique (aluminum oxide particles 50 μm) with the application of primer MZP before using resin cement (P < 0.05) independent of the metal type used. The metal type did not significantly affect SBS for any of the compared surface pretreatments.Conclusion:Metal primer application significantly enhanced SBS to base and a noble metal. No significant differences in shear strength were found between alloys.

“…They require a three‐step procedure (etch, bond and resin) as do the materials in our first division and display similar physical characteristics but they are uniquely different in that they have been chemically modified to have very high tensile strengths and tenaciously bond to etched enamel and electrolytic etched or micro‐abraded base metal and noble metal alloys. Bonding to tooth structure is very technique sensitive and bonding to metal varies with the alloy and is enhanced with the use of special metal primers 1,22,23 …”

A luting agent's primary function is to fill the minute void between an indirect restoration (definitive or provisional) and tooth (or implant abutment) and mechanically lock the restoration in place to prevent dislodgement during function. The purpose of this paper is to provide a clinically focused discussion on the broad spectrum of luting materials currently available to help the general practitioner make appropriate choices. Resins are typically formulated for a specific function or restoration and offer strength, aesthetics, flexible working times, and very low solubility yet are technique sensitive, expensive and often hard to clean-up. Glass-ionomers offer good strength and optical properties plus the potential for fluoride release ⁄ recharge but may have short working times, are sensitive to moisture or dehydration early on, and take time to fully set. Resin-modified glass-ionomers are hybrid, dual-phase materials which are manipulated like glass-ionomer but set quicker and are stronger. Zinc phosphate cement, used successfully for over a century to lute well-fitting metal and metal-ceramic definitive restorations, is a very inexpensive, rigid material which displays very high early compressive strength yet acidity and solubility can be problems. Polycarboxylate cement (a hybrid of zinc phosphate) has lower compressive strength but high tensile strength and may be less injurious to the pulp. Zinc oxide eugenol and zinc oxide noneugenol cements typically have good sealing abilities but their relatively low compressive and tensile strengths, inherent brittleness, and high solubility limit usage to provisional restorations or implant supported crowns. Claims for multipurpose or universal use by manufacturers can be somewhat confusing and overwhelming. Even so, the busy general practitioner must have sufficient knowledge to help choose an appropriate luting agent for each unique clinical situation.
