Concluding remarks Purists may su ce with a universal composite as the sole direct restoration material inpractice.However, for theroutine restoration of Class I and II restorations, I now see bulk- ll composites as the material of choice. Clinically equivalent to conventional composites, they facilitate the work and shorten the vulnerable period of the restoration, especially if no rubber dam is used for insulation. In addition, the 4mm Tetric PowerFill and PowerFlow composites shown here, together with the innovative Bluephase PowerCure, o er the possibility of ultra-short polymerisation if desired. In the anterior region and for aesthetically sensitive restorations in the posterior region, Tetric Prime complements all other indications that occur in everyday practice. u

occlusal contacts that lie directly on the proximal edge bars (Fig. 25) must always be completely removed in order to avoid the risk of proximal chipping under chewing load. e main reason for the failure of

composite restorations is the fracture of the restoration 7 . If you follow the rule just mentioned, you can reduce this problem considerably. Figure 26 shows the nished restorations.

Fig. 23: The separation ring is reinserted. This means that there is only one die left in the interdental space before the restoration of the 2nd cavity and a tight contact can be achieved effortlessly.

Fig. 22: The die of the filled tooth 34 is now slightly loosened and pulled out of the proximal space at the side. It is always pulled in the direction of the tip of the interdental wedge (yellow arrow). In this way, the die of the adjacent tooth remains in place. Tweezers are usually sufficient to pull out the die, otherwise the die can also be grasped with pliers.
