26 I I case report _ veneering technique nation with the fixing composite is a 100 per cent bond, which means that there is only one homo- genous coating of composite on the tooth, thereby increasing the strength of the final result and re- ducing the tendency to discolour. For an appropriate aesthetic success SYNERGY D6 is recommendable, which is ideally matched in shade to COMPONEER. It can also be used with other systems, in which case testing the shade result before use is highly advisable. If it is necessary to remove fillings first, COMPONEER can be applied with the correspond- ing dentine mass and filled from the palatal direc- tion after the initial lightcuring. This can also be done for tooth extensions or diastema closure. On the other hand, cavities can be filled beforehand with dentine mass to establish a homogenous base. Enamel mass can be used for shape corrections or simple shading corrections. Too much enamel will make the restoration grey and too transparent. The composite is applied to the side of the composite shell that is to be fixed with a suitable instrument, e.g.theincludedMB5spatula(Fig.7).Thecomposite isalsoappliedtothetoothtopreventairinclusions. Then the COMPONEER is carefully placed in its final positionwithconstantgentlepressurebytheplacer (Fig. 8). The placer has been specially developed for positioning veneers. The working tip is a silicone knob, which provides ideal force distribution. For complete front tooth restorations, I recommend startingwiththetwocentralincisors.Withtheshell held in position, large residues are removed and the composite is shaped to match the margins. The light-curing process is not started until the correct position of the veneer has been verified. Then obvi- ous residues are removed or the preliminary con- touring is carried out. Finishing and polishing strips can be used for the proximal regions. Flexible discs are the best tools for shaping interincisal angles. Duetoitssmoothanatomicalstructureitispossible to individually characterize the surface or to adapt the shape to the face, bipupillary plane or lip line (Figs. 9 & 10). Microbrushes used without water are ideal for the final polishing to achieve the optimum high gloss (Fig. 11). The complete homogeneity of the composite shells means that the final finishing is in no danger of bringing unwanted porosities to the surface (Figs. 12 & 13). A glossy composite sur- face of the highest quality for longlasting aesthetics is the final result. The COMPONEER, manufactured from high-quality composite, can be considered as aids for shaping. They are primarily used for making the complete anterior region of the teeth more attractive and guarantee an easily achieved and high-quality result. At the same time, they promote efficient working and reduce treatment time by as much as 40 per cent. This is good for the dentist and also more comfortable for the patient. _Conclusion The innovative composite veneering technique optimises and simplifies restorative dentistry and offers new options for function, economy and aesthetics that benefit both patients and dentists.
