Due to the rise over the years in patient emphasis on better esthetic outcomes, veneering the metal base of a restoration with composite resin or porcelain is widely used in dentistry. For the preservation of the opposing natural dentition and the potential for repair, the use of composite veneering materials has been suggested because of their resilience, low abrasive properties, and superior repair potential. Composites are not as popular as porcelain, but they are still widely used to cover metal because of low cost and because the laboratorial procedures are faster and simpler.

This article presents a case report of missing maxillary anterior teeth treated with FPD having laboratory composite resin veneer.

   Case Report Top

A patient reported with the chief complaint of missing anterior teeth. She had lost her both central incisors two years back due to an accident.

Clinical and radiographic examination did not reveal any periapical pathological condition. Fixed replacement was planned using the lateral incisors present on either side as abutments. Shade matching was done using shade guide. Preparation of the maxillary lateral incisors was done for FPD with labial composite facing. The labial margin was deep shoulder, and all the other margins were chamfer finish line.

Double step putty-wash impression was made for the preparation of the working model. It was poured in high strength die stone. The provisional prepared was cemented with temporary luting cement.

Wax patterns were made using inlay wax. Retention beads were used on labial aspect to provide mechanical retention for composite veneering material. Casting was done using Ni-Cr alloy in an induction casting machine. After finishing of metal framework, metal try-in was done [Figure 1].

The framework was sandblasted, and SR link was applied. The desired amount of opaquer paste (SR Adoro) was removed from the syringe and applied after slightly spreading out on a mixing pad using a disposable brush. Precuring was carried out for 20 seconds, using the Quick curing light [Figure 2]. Second opaquer layer was applied in such a way to completely cover the first layer and precured for 20 seconds with the Quick light curing unit. After precuring, the samples were polymerized using a special curing chamber Lumamat 100 (11 min). A disposable sponge was used to thoroughly remove the inhibition layer formed during the curing. It was made sure that the surface of the opaquer had a silky mat finish.

Sequential build up was done using Adoro dentin and cured using Quick cure unit. After obtaining the satisfactory shape and contour, SR gel was applied on the veneering composite to minimize the formation of an inhibition layer on the surface of veneering composite. All exposed alloy parts of the framework were covered homogenously with thermal conducting paste (Thermo Guard), thereby minimizing the internal tension at the interface between metal and veneering resin. The final curing was carried out using the special curing chamber [Figure 3]. A 22 minute curing cycle was carried out, which included precuring for ten minutes, tempering at approx 104°C/219°F for seven minutes and cooling for five minutes. After completion of the polymerization/tempering procedure, the specimen was cleaned using a steam blaster. The restoration was cemented using GIC luting cement [Figure 4].

   Discussion Top

Clinicians and patients have always sought restorations that closely resemble natural teeth. This esthetic demand has risen through the years and is achieved in many instances by veneering the metal base of a restoration with resin or porcelain. Clinicians have encountered problems with early generation methyl methacrylate resins, such as marginal percolation, discoloration, low abrasion resistance, and poor dimensional stability. [1] The metal-ceramic crown application has been a successful dental restoration for more than 30 years and the most popular indirect restoration; however, questions remain about the optimal condition of the alloy during application of opaque porcelain and firing procedures. [2] Porcelain facings do not wear, they have good color stability, and marginal leakage is not a problem, yet they have their limitations such as brittleness, abrasion of opposing teeth, subject to crack propagation, and difference in coefficient of thermal expansion between metal and porcelain. [3] To overcome the drawbacks of these materials, laboratory cured composite veneers have been introduced as an alternative veneering material to porcelain and acrylic resin. The advantages of light-cured veneering materials include favorable esthetics, abrasion characteristics similar to that of natural tooth substance, repairability, and fast, simple laboratory procedures.
