Step-by-step:

1. During the first session the old fillings were removed from the upper first premolar and molar. Using dental floss as a measurement two-pieces of EverStick fibers were cut and pressed together using tweezers. The fiber bundle was moistened with flow-micro hybrid composite. After etching and bonding, the borders of the proximal cavities were sealed with a layer of flow composite that was light cured. Then a thin layer of flow composite was applied on the cavities and the EverStick fiber bundle was positioned to its place. Finally, the light curing of the fiber bundle was done using the Turbo-curing tip. The pontic and the associating structures on the supporting teeth were constructed using universal micro hybrid composite in layers.
2. Occlusion was checked and all the other surfaces, including the base of the frame, were finished and polished. The whole bridge was then treated with phosphoric acid gel and non-filler resin and light cured. Oxygen inhibition layer was removed with ethanol saturated cotton balls. The occlusion of the upper jaw was checked a week later. In the same session a fiber reinforced bridge was constructed for the lower jaw.
3. The amalgam was removed from the lower second molar and the provisional glass ionomer protection was then removed from the lower first premolar. The lingual surface of the lower canine and the lower incisor were prepared with a finishing-diamond bur. Two EverStick fibers for the bridge frame were cut to suitable length with the help of dental floss as measurement. In addition, an extra piece of fiber for joining together lower second premolar and lower second molar was cut. The fiber bundles were joined and moistened with flow composite. The prepared fiber was placed in a light protected container.
4. Some height was built with composite to the lower second premolar prior to the placing of the fiber. After light curing the adhesive the base and the proximal edges of the cavity were contoured with flow composite. The proximal cavity of the second molar was sealed and contoured with flow composite. After light curing a thin layer of flow composite was applied into the cavities and on the lingual surfaces of the lower incisor and the lower canine. The fiber bundle was placed into the cavities. The fiber bundle was light cured gradually the final light curing was done with a Turbo curing tip. The pontic and the associating structures on the supporting teeth were prepared with micro hybrid composite. After light curing a primary finishing was done for the bridge. Occlusion was controlled and all the other surfaces finished. Following finishing and polishing the bridge was treated with phosphoric acid gel and resin as described above. It was then light cured and the oxygen inhibition layer was removed with ethanol.
5. Two further appointments were arranged in one week's intervals to control the occlusion level. After six months during a control appointment both bridges are found to be in a faultless condition. A slight reduction of the upper and lower second premolars intercuspidation for the side movements was done.
