Disadvantages of Directly Placed Resin Composites

Probably the most significant disadvantage with directly placed resin composites is the clinical time needed to produce an aesthetic result. Even though porcelain veneers involve a laboratory phase and consequently additional cost, it is the technician who spends the time shaping, contouring and colouring the restoration. The clinician need only lute the restoration into place. For some clinicians, the concept of a directly placed resin composite veneer is challenging and clinically satisfying, while for others this time is not well spent and they prefer the support of a technician.

Until recently, directly placed resin composite veneers lacked depth or variation in colour. Microhybrid resin composites overcome this to a large extent, but the clinical time needed to place these materials to good effect has increased significantly. More translucent enamel shade on the incisal tips can produce very acceptable results but can produce unacceptable ones if too much is used or they are used indiscriminately (Fig 4-2). Readers are referred to the Further Reading section for advice on selection of resin composites.
