As a result of an increasing demand for fabricating metal-free restorations and parallel with the developments in computer-assisted design and computer-assisted manufacturing (CAD-CAM) technology and materials, CAD-CAM high-performance polymers (HPPs) have been introduced as alternative materials to titanium and zirconia. 1-8 HPPs have been increasingly used as a framework material for fixed and removable prostheses and for implant-supported prostheses. These materials have been reported to have favorable thermal and mechanical properties. 1,9-11 Polyaryletherketones (PAEKs) and modified composite resin (MCR) polymers are currently available HPP materials. 6,11-17 Polyetheretherketone (PEEK) and polyetherketoneketone (PEKK) are 2 main groups of the PAEK polymer family that contain an aromatic backbone molecular chain, interconnected by functional ketone and ether groups. 1,2,10-12,16,18-20 PEEK and PEKK are high-temperature semicrystalline thermoplastic polymers with linear chain structures. 10-12,16,18-20 PEEK has been reported to be easily machinable, have low solubility and water absorption, and have high polishability and stability in terms of hardness, rigidity,

“…Researchers have recently focused on laser application to enhance the bonding of different dental materials such as ceramics and resin-based materials. 15,17,28,31,[40][41][42][43] The Er:YAG laser is the most commonly used laser type for the surface treatment of dental materials. 29,31 Different energy levels of the Er:YAG laser have been used by investigators.…”

“…[25][26][27] On the other hand, the majority of studies on the surface treatment of PEEK with lasers have focused on the bond strength of PEEK to resin cement and have reported controversial results. 15,17,28 A search of the literature by the authors revealed one previous study on the effect of Er:YAG laser treatment on bond strength of composite resin veneers to PEEK. They observed that a combination of airborne-particle abrasion or silica coating with Er:YAG laser irradiation provided a durable bond while the Er:YAG laser beam alone did not enhance the bond strength.…”

Effect of Surface Treatment With Er:YAG and CO2 Lasers on Shear Bond Strength of Polyether Ether Ketone to Composite Resin Veneers

Introduction: Polyether ether ketone (PEEK) has low surface energy and high resistance to chemical surface treatments. Therefore, different surface treatments such as laser conditioning should be investigated. There is a gap of information regarding the efficacy of laser irradiation in the surface treatment of PEEK, and the efficacy of several laser types needs to be evaluated for this purpose. This study aimed to assess the effect of surface treatment with erbium-doped yttrium aluminum garnet (Er:YAG) and carbon dioxide (CO2) lasers on shear bond strength (SBS) of PEEK to composite resin veneers. Methods: In this experimental study, 60 rectangular-shaped PEEK samples (7 x 7 x 2 mm) were used. The samples were mounted in auto-polymerizing acrylic resin in such a way that only one surface measuring 7x7 mm remained exposed. The samples were then randomly divided into 3 groups (n=20) of control, Er:YAG laser surface treatment (Power=1.5 W, energy density=119.42 J/cm2 , irradiation time=20 s) and CO2 laser surface treatment (Power=4 W, energy density=159.22 J/cm2 , irradiation time=50 s). The bonding agent and PEEK opaque were applied on the surface of samples and they were veneered with a composite resin using a hollow plastic cylinder with an internal diameter of 4 mm. The SBS was then measured and the data were analyzed using one-way ANOVA, Tukey HSD test and Dunnett’s test at 0.05 level of significance. Results: The SBS of the 3 groups was significantly different (P<0.001). The Tukey HSD test revealed that the Er:YAG laser had higher SBS than the CO2 laser group (P<0.001). The Dunnett’s test showed that both Er:YAG and CO2 laser groups yielded higher SBS than the control group (P<0.001). Conclusion: The Er:YAG and CO2 laser treatments can increase the SBS of PEEK to composite resin veneers, although the Er:YAG laser seems to be more effective for this purpose.

“…In the last decade, with the advancement of laser techniques, the use of lasers as an alternative pretreatment method for dental procedures has become prevalent, such as by applying laser treatment to dental materials to improve the bonding properties between materials and resin-based luting agents [24] or materials and porcelain [25]. This resulted in the attempted use of lasers as a surface treatment method for zirconia ceramics, in order to enhance the bonding strength and durability of a number of dental materials by altering the surface microstructures [26][27][28].…”

Laser-Milled Microslits Improve the Bonding Strength of Acrylic Resin to Zirconia Ceramics

Heightened aesthetic considerations in modern dentistry have generated increased interest in metal-free “zirconia-supported dentures.” The lifespan of the denture is largely determined by the strength of adhesion between zirconia and the acrylic resin. Thus, the effect on shear bond strength (SBS) was investigated by using an acrylic resin on two types of zirconia ceramics with differently sized microslits. Micromechanical reticular retention was created on the zirconia surface as the novel treatment (microslits (MS)), and air-abrasion was used as the control (CON). All samples were primed prior to acrylic resin polymerization. After the resin was cured, the SBS was tested. The obtained data were analyzed by using multivariate analysis of variance(α = 0.05). After the SBS test, the interface failure modes were observed by scanning electron microscopy. The MS exhibited significantly higher bond strength after thermal cycles (p < 0.05) than the CON. Nevertheless, statistically comparisons resulted in no significant effect of the differently sized microslits on SBS (p > 0.05). Additionally, MS (before thermal cycles: 34.8 ± 3.6 to 35.7 ± 4.0 MPa; after thermal cycles: 26.9 ± 3.1 to 32.6 ± 3.3 MPa) demonstrated greater SBS and bonding durability than that of CON (before thermal cycles: 17.3 ± 4.7 to 17.9 ± 5.8 MPa; after thermal cycles: 1.0 ± 0.3 to 1.7 ± 1.1 MPa), confirming that the micromechanical retention with laser-milled microslits was effective at enhancing the bonding strength and durability of the acrylic resin and zirconia. Polycrystalline zirconia-based ceramics are a newly accessible material for improving removable prosthodontic treatment, as the bond strength with acrylic resin can be greatly enhanced by laser milling.
