To evaluate the influence of different materials on the load-bearing-capacity of inlay-retained fixed-dental-prosthesis (FDP). Ten types of FDPs were evaluated (n=7/group): Group PEEK: CAD-CAM polyetheretherketone (PEEK-TechnoMed), Group RC, made of discontinuous-fiber-composite (EverX Posterior); Group FRC1, made of discontinuous-fiber-composite (EverX Posterior) with two-bundles of continuous-unidirectional fiber-reinforced-composite (FRC) (Everstick C&B); Group FRC2, made of discontinuousfiber-composite (EverX Posterior) with two-bundles of continuous-unidirectional-FRC (Everstick C&B) covered by two-pieces of short-unidirectional-FRC (Everstick C&B) placed perpendicular to the main-framework; Group FB, CAD-CAM fiber-block (FibraComposite Bio-C); Group PMMA, CAD-CAM polymethyl methacrylate block (Temp basic); Group RP, resin-paste; Group FRP1, made of resin-paste (G-Fix) with two-bundles of continuous-unidirectional-FRC (Everstick C&B); Group FRP2, made of resin-paste (G-Fix) two-bundles of continuous-unidirectional-FRC covered by two-pieces of short unidirectional-FRC placed perpendicular to the mainframework and Group exp-FRC, experimental CAD-CAM FRC. The bridges were statically-loaded until fracture. Fracture modes were visually examined. ANOVA revealed that significant differences were observed between FDP-materials (p<0.05). In addition, fiber addition to the framework significantly affected load-bearing-capacity (p<0.05).

“…21 One study has examined the impact of plasma with cold active inert argon gas for 20 seconds (0.2 MPa) at a distance of 10 mm on adhesion between PMMA and composite resin cements. 19 Another study examined the influence of plasma pretreatment between PEEK surface and self-adhesive resin cements with the same parameters and reported no effect. 7 In the latter study, different plasma treatment parameters were tested, such as different plasma treatment times (5 to 120 seconds), pressures (0.05 to 0.6 MPa), and different gas (argon/helium),;however, no impact on the fracture load results was observed.…”

“…3 Plasma treatment offers another approach to raising the wettability of materials and could be an alternative approach to ensure higher bond strength to resin materials. 19,20 Plasma is an ionized gas with essentially equal density of positive and negative charges, whereas an alternating electrical field at microwave or radio frequencies to electrodes can applied by using the latter. A new surface layer is then built through excited molecules that will excite other species, which leads in a chemical way to an interaction with the surface.…”

STATEMENT OF PROBLEM Polyetheretherketone (PEEK) can be used as a framework material for fixed dental prostheses (FDPs). However, information about the fracture load of veneered PEEK FDPs is still scarce. PURPOSE The purpose of this in vitro study was to investigate the influence of different PEEK surface pretreatments and adhesive systems on the fracture load of 2 differently veneered FDPs. MATERIAL AND METHODS Four hundred eighty anatomically shaped 3-unit PEEK frameworks were milled, airborne-particle abraded with 50 m alumina powder, and divided into 4 groups according to the following surface pretreatment (n=120): plasma treatment, etching with either sulfuric acid or piranha solution, and no further treatment. All groups were then allocated to 4 conditioning groups: visio.link, Ambarino P60, Signum PEEK Bond, or no conditioning. They were veneered with Signum Composite (n=15) or Signum Ceramis (n=15). Upon completion, the FDPs were thermally aged, and fracture loads and failure types were determined. Statistical analysis was performed with 3/2/1-way ANOVA with the post hoc Tukey HSD test (=.05). RESULTS The highest fracture loads were achieved without treatment in combination with visio.link (737 ±138 N). The lowest values were obtained after piranha acid etching and conditioning with visio.link (277 ±71 N); both groups were veneered with Signum Composite. The results, however, indicated no clear influence of either pretreatment or conditioning. With few exceptions, FDPs veneered with Signum Composite showed higher fracture load values compared to Signum Ceramis. After thermocycling, all FDPs showed cracks in the veneering composite resin material in the pontic region, regardless of the PEEK pretreatment or the adhesive system used. After loading, no fractures of the PEEK frameworks were evident in any FDPs, but chipping of the veneering material was observed. CONCLUSIONS With respect to the fracture types after thermocycling, pretreatment, conditioning, or veneering resin cement did not affect the fracture results.

“…A variety of studies of bond strength between veneering resin composite and PEEK-framework have been performed already, in which different pre-treatments of the airborne-particle abraded surface with piranha-etching [13,14,15,16], sulfuric acid [5,9,12,17] and cold plasma treatment [18,19] were tested, providing, however, some conflicting results. Some of these studies examined the influence of the adhesive on the bond strength to PEEK and the vast majority showed nevertheless adequate bonding results with MMA-based adhesive materials comparable to those of conventional framework materials like ceramic or metal alloys [14,15,16,20,21,22].…”

OBJECTIVE The aim of this study is to investigate the fracture load of different veneered PEEK 3-unit fixed dental prosthesis (FDPs) after different aging regimens. METHODS Congruently anatomically shaped 3-unit FDPs were milled using a master stl-data set and randomly divided into four groups (N = 120, n = 30 per veneering group), which were veneered using different veneering methods: (i) digital veneering with breCAM.HIPC, (ii) conventional veneering with crea.lign, (iii) conventional with crea.lign paste, and (iv) using pre-manufactured veneers visio.lign. The FDPs were then adhesively cemented on a metal abutment and fracture loads were measured in a universal testing machine (1 mm/min) before and after aging (10,000 thermal cycles, 5/55°C). Two-and one-way ANOVA followed by post hoc Scheffé tests were used for data analysis (p < 0.05). RESULTS This investigation showed an influence of the veneering method on the fracture load results independent of the aging level. The highest fracture load was measured for the FDPs with digital veneering (1882 ± 152 N at baseline, 2021 ± 184 N after thermocycling). The remaining groups showed comparable results, and no impact of thermal aging was observed. Digital and conventional veneers showed cracks in the pontic region starting from the connector area as a main failure type after loading, while the pre-manufactured veneers showed predominantly adhesive failures. CONCLUSIONS The digital veneering method showed the highest fracture load resistance. Thermal aging showed no impact on the fracture load of all tested veneered PEEK 3-unit FDPs. CLINICAL RELEVANCE According to this study results, reliable veneering of PEEK FDPs can be achieved with digital veneering. Clinical relevance According to this study results, reliable veneering of PEEK FDPs can be achieved with digital veneering.
