The dentist will administer local anesthesia (see Chapter 14). The assistant will prepare and assist in the type of moisture control (cotton roll, dry angles, dental dam) to be used for the procedure (see Chapter 10). The dentist will prepare the tooth, including using dental hand instruments and dental handpieces with rotary instru- ments (see Chapter 19). The dentist will specify which dental materials are to be used (see Chapter 20). The assistant will prepare and assist in the placement of the dental materials. The assistant will prepare and assist in checking the occlusion. The dentist will finish and polish the restoration. See Procedure 21-4: Assisting in a Class II Amalgam Restora- tion, and Procedure 21-5: Assisting in a Class III or IV Com- posite Restoration. Complex Restorations If the loss of tooth structure is greater than the remaining natural tooth, then the dentist must decide whether to (1) move ahead and restore the tooth with an amalgam or a composite material, or (2) change the treatment plan and replace the tooth structure with a cast restoration. Bonding techniques and reten- tion pins are best suited for use in teeth that require very large restorations with little tooth structure remaining to provide strength and retention for the amalgam. Retention pins provide internal strength to the placed mate- rial (Figure 21-7). These pins are available in a variety of diam- eters (widths) and styles to fit all sizes of teeth. Because all retention pins are very small (approximately one half the size of a bur) and are easily dropped, the dental dam should be indicated for this procedure. Veneers A veneer is a thin layer of tooth-colored material that can be directly bonded onto the tooth or fabricated in the laboratory using a porcelain material and then cemented to the tooth surface (Figure 21-8). Veneers are used to improve the appearance of teeth that are slightly abraded, eroded, or discolored from stains or from endodontic treatment. Veneers can also be used to improve the alignment of teeth or to close a diastema. Vital Bleaching Vital bleaching, also referred to as tooth whitening, is a tech- nique that involves the whitening of the external surfaces of the teeth. This desired whitening is completed for esthetic purposes, not for restorative purposes (Figure 21-9). FIGURE 21-8 Veneers placed on teeth #8 and #9 to reduce discoloration and to cover stain.

A B CHAPTER 21 Restorative Procedures 335 bonding material may be required before the amalgam or com- posite is placed. Matrix Systems A tooth that is to receive a Class II, III, or IV restoration will have a minimum of one interproximal wall or surface of the tooth removed during the cavity preparation stage. By including the use of a matrix system, a temporary wall is created, against which the restorative material is placed until the material has set. The universal retainer and matrix band is the system most commonly used when placing posterior restorations (Figure 21-1). The retainer firmly holds the matrix in place. A matrix is a metal or clear plastic band used to replace the missing proximal wall of a tooth during placement of the restorative material. (Matrix is singular. The plural form is matrices.) Clear plastic matrices are used for anterior composite restorations. A wedge is triangular or round and is supplied in wood or plastic (Figure 21-2). The wedge is available in different sizes, depending on the location space between the teeth. By Cavity Preparation Regardless of the type of dental material selected, understand- ing the steps of a restorative procedure is important. The steps include removal of the decay by the dentist, preparation of the tooth cavity, placement of dental materials, and finishing the restoration. The most detailed part in restoring a tooth is the cavity preparation. The purpose of cavity preparation is to remove the decay along with a small amount of healthy tooth structure, which, when completed, provides a solid foundation for the restorative dental material to be placed as a final restoration. To understand the different types of tooth preparations, you can review the types of cavity classifications in Chapter 12. The dentist will use a high-speed handpiece with a variety of burs and hand instruments to accomplish this preparation step. Once the decay is removed, the dentist will use the high- speed handpiece with a different-shape bur to place retentive grooves in the preparation. These small grooves in the tooth allow the material to flow into the groove area, harden, and create the retentive result. In the next step, the dentist determines the type of restorative material that will be used. This decision is based on the size, shape, and location of the preparation. With small preparations, an amalgam or composite material can be directly placed over sound dentin. With deeper preparations, a cavity liner, base, and FIGURE 21-1 Matrix and wedge correctly positioned. FIGURE 21-2 Assortment of wedges.

The common types of pro- cedures include amalgam restorations, composite resin restora- tions, and complex restorations. Esthetic dentistry is directed on improving the appearance of teeth by restoring imperfections with direct and indirect restorative materials or with the use of whitening techniques. The common types of procedures are composite resin restora- tions, resin veneer restorations, and tooth whitening. 336 PART Eight Restorative Dentistry FIGURE 21-3 Assorted matrix bands.

To contour the band, place the band on a paper pad, using a burnisher or handle end of cotton pliers. Rub the inner surface of the band until the ends begin to curl. This thins the band and provides a normal curvature of the band to fit around the tooth. Universal Retainerthealso The universal retainer, referred to as Tofflemire retainer, is a device that holds matrix band in position. The compo - nents of the universal retainer are described in the box titled Components of a Universal Retainera.”Matrix See Procedure 21-1 : Assembling Band and Univer- sal Retainer. 1. Spindle: This internal screwlike pin fits into the diagonal slot to hold the ends of the matrix band. When the retainer is assembled, the spindle point must be clear of the slot while the band is slid into the slot and then tightened. 2. Outer guide slots: Also known as guide channels,andretainer these slots are located at the end of the serve as channels to guide the loop of the matrix band. The channel selected is determined according to the quadrant that is being treated. 3.
