A sectional precontoured metal matrix to improve the pontic contour and emergence profile for fiber-reinforced composite resin fixed dental prostheses
Fixed dental prostheses made with fiber-reinforced composite resin are a conservative and cost-effective option for replacing a missing tooth.1 This type of prosthesis can be fabricated directly or indirectly,2,3 but the direct technique is challenging and susceptible to error; in addition, shaping the pontic is difficult.4Use of extra-fine crosscut bur to produce horizontal texture in composite resin restorations
Reproducing the developmental lobes and perikymata of the anterior teeth of young patients with composite resin restorations is a clinical challenge.1-3 Different finishing and polishing systems and techniques are available, although a standard protocol is lacking. The selection of the correct instruments will depend on the position of the tooth and the type of surface to be reproduced. Multibladed and diamond rotary instruments and abrasive rubber points are commonly used for this procedure.4
