application with the tip of a probe, (D) adhesive resin application, (E) repair of the cusp with resin composite 13.4 Metal Ceramic Fixed Dental Prosthesis Failures and Repair Protocol Despite the increased effort to improve the bond between ceramic materials and metal substrate, fractures of ceramic-fused-to-metal FDPs still occur The reasons for failures cover a wide spectrum from thermal mismatch between the veneering ceramic and the metal framework, lack of calibration of the ceramic oven, laboratory mistakes, to iatrogenic causes, or that they are merely related to the inherent ă zcan, 2003a) The reasons for such failures are usubrittleness of the ceramics (O ally, due to lack of slow cooling of the furnace, lack of anatomical support of the framework, inadequate framework-veneer proportion, inadequate firing procedures, lack of compatibility in thermal expansion coefficients of framework While early fractures are due to technical problems, the late fractures are frequently due to www.ajlobby.com Maintenance care and repair of dental restorations using fiber-reinforced resin composites 219 Figures 13.2 (A) Large amalgam exposure associated with cusp fracture on a maxillary molar, (B) intra-oral air abrasion of amalgam, (C) silane coupling agent application, (D) opaque resin application and the addition of E-glass woven fiber (0.6 mm) for interfacial reinforcement, (E) adhesive resin application, (F) repair of the cusp with resin composite (buccal view), (G) repair of the cusp and refurbishment of the old amalgam in an attempt to prolong service life of a defect restoration (occlusal view) ă zcan, 2003a) Repairing repeated stresses and strains during chewing or trauma (O FDPs in vivo can increase the clinical longevity of the failed restorations, thereby offering the patient and the dentist a cost-effective alternative to replacement However, the repair of fractured metal-ceramic FDPs represents a potential clinical challenge, particularly when the metal substructure has been exposed, and when ă zcan and Niedermeier, 2002) bonding of resin to metal alloy is required (O (Fig 13.3) The use of E-glass fiber weaves impregnated with polymer-monomer gel resin in case of large metal exposure was shown to increase repair strength and cause excluă zcan et al., 2006b) (Fig 13.4) sively cohesive failure between in the FRC itself (O This indicates that FRC provides a strong bond of the veneering repair resin on the metal/ceramic surface Polymethylmethacrylate enrichment on the fiber weave surface needs to be treated with a resin having a dissolving parameter of PMMA, or extensive resin treatment times are needed which may be in some cases not possible for direct repairs The higher results obtained with the use of FRC weaves in metalceramic repairs imply the following: the stress concentrations in the repaired crowns cause initiation of a crack, and it propagates through the resin until it meets the FRC layer with continuous fibers that stop the crack or deviate the direction ă zcan et al., 2006b) (O Repair actions could be performed multiple times One could expect that after each repair cycle, the repair surface area changes Nevertheless, air-abrasion of the metal surface, HF etching the ceramic margins, and application of 0.6 mm E-glass ă zcan woven fiber increases the adhesion of the repair composite to metal-ceramic (O et al., 2006b) www.ajlobby.com 220 Clinical Guide to Principles of Fiber-Reinforced Composites in Dentistry Fracture strength (final failure) 1400 1200 Original crowns

using different surface condition methods Note that the use of E-glass woven fibers at the metal-repair resin interface restored the fracture strength to the original fracture strength of the metal-ceramic crown Figures 13.4 (A) Adhesive failure type with metal exposure when metal surface was only air-abraded, silanized and with opaque resin coated, (B) Cohesive failure type in the fiber when two layers of E-glass woven fibers of 0.6 mm were used to increase the interfacial strength Both metal and ceramic substrates require different conditioning methods with etching gels, adhesive promoters, and/or abrasives Thus, the sequence of repair protocol may affect durable adhesion of repair composite to these substrates Chippings or fractures of veneering ceramic are multifactorial, one of which is the presence of premature contacts This could be the underlying cause for failure and should be eliminated prior to repair procedures The color match between www.ajlobby.com Maintenance care and repair of dental restorations using fiber-reinforced resin composites 221 ceramic and resin composites, especially in the visible anterior areas, is crucial as the two materials have different surface properties and color stability Rubberdam will protect the soft tissues from hazardous hydrofluoric acid (HF) that will be used later for conditioning the veneering ceramic Ceramic and metal surface should be cleaned using fluoride-free paste or pumice Glaze of the veneering ceramic surface at the margins to be repaired should be removed using fine grit diamond bur under water-cooling and bevel should be created Undisturbed glaze layer with concentrated glass particles will not react with HF and subsequent application of silane coupling agents Removal of the glaze layer would also increase the surface area on ceramic for mechanical retention and allow for the reaction of silane with the glassy matrix Accidental deposition of particles during conditioning the exposed metal by air-abrasion may remove the glaze on the veneering ceramic Thus, the veneering ceramic, except the bevelled area, should be coated using glycerin gel The metal surface should be air-abraded using a chairside air-abrasion device, preferably with alumina particles coated with silica or silica only (particle size range: 30À50 µm; blasting pressure: 2.5 bar), for approximately seconds until the metal surface turns matte, from a distance of approximately 10 mm in circling motion, rotating the nozzle After washing and rinsing under copious water and drying, the ceramic margins where the repair composite will be adhered to should be etched with 5% or 9.6% HF for 20 or 90 seconds depending on the ceramic type After rinsing and neutralizing the surface, silane coupling agent should be applied on both the metal and the ceramic surface, one layer, and a minute wait for its reaction The metal surface would be then masked with opaque resin based on the powder-liquid system as described above At this stage, in case of largely exposed metal surfaces, one or two sheets of 0.6 mm woven E-glass fiber could be applied to increase interfacial strength Then, adhesive resin should be applied and photo-polymerized for 20 seconds After completion of incremental repair resin application, and polymerization, premature contacts should be eliminated and finishing and polishing should be performed accordingly 13.5 Concluding Remarks and Future Trends Repair of failed restorations due to technical reasons or fatigue could prolong the survival of functioning restorations However, it has to be made sure that the underlying reason for the failure does not constitute the fundamental reason for failure If this is the case, restoration needs to be replaced Nevertheless, in addition to the use of physical, chemical, and physicochemical conditioning methods, the use of woven E-glass fiber sheets increases interfacial strength and thereby contributes to more durable repair actions Although interfacial strength is increased in repairs, degradation of repair resin surface may again require additional repairs during the whole course of service life of a
