1. Initial state
2. Before treatment, perform a jaw plaster model, rehearse, work on the future, and a wax. The wax model was based on the palatal silicon index of the teeth.
3. Very large gap
4. Initial state
5. Initial state
6. Side view
7. Gingival very large nipple
8. Small tool wear
9. When planning such clinical cases, it means looking forward to the shape of teeth in the future, it is important to understand what makes the proportion harmonious, so it is necessary to increase not only the width of teeth, but also their height. In most clinical cases, dentists can increase the height of teeth on the cutting edge. However, in order to protect the edge overload, in this case, the height of the dog must also be increased.
To create this form, it is necessary to make the material actually between the teeth under the gum. So what should we do?
10. Color selection
11. The first stage of treatment. Isolation is one of the two incisors
12. No preparation - sandblasting the near middle surface of the tooth, using etching and adhesive preparation.
13. Then a circular shape of the polyester film matrix composite is used, and a small part is added on the side surface of a small compression rubber tooth.

15. The same procedure was performed in the other central incisors.
16. As a result, a small effort, part recovery, shaping is more challenging. In addition, these composite add-on inserts allow the floss to be kept in place behind the rubber dam at the neck of the tooth.
17. Treatment - second stage tooth preparation.
18. In this process, it is necessary to control the amount of silicon removed based on wax.

25. Compound ceram-x binuclear E2 was applied to the palatal enamel of silicon bond.
26. The procedure was carried out in four incisors.
27. The space between the enamel layer and the teeth of the slit is filled with a small amount of flowing compound curtain oa3.
28. This can fill the space without pore formation.
29. Introduce the quality of composite ceram-x stack D2 to dentin.

38. Application layer enamel A1
39. Application layer enamel version A1
40. Apply a layer of translucent enamel CE.
41. Introduction of composite material on the side surface with transparent plate.
42. To obtain access to the gingival papilla in the most difficult place, we use the following method. A circular posterior metal matrix is introduced between the teeth. One edge of the matrix pushes the gingival papilla to make room where we need to enter the composite. First, the program is carried out with the first center knife, second.
43. There are very important conditions. The successful addition of this material is the careful grinding of subgingival composite material and the place where the composite material in the root transits.
44. This is with abrasive belt.
45. Grinding
46. At the end of the first visit, the rough contour was repaired. All the next steps in the next visit.
47. 3 days after the next occurrence.
48. Palatal milling cutter with large overhang and sharp edge.
49. This visit is the correction of defect repair, and the center line of slight displacement carries out complex repair of the whole project.
50. This stage is a special video.

conclusion
There is great potential in the direct method to repair the large tooth gap with composite materials. Making an indirect porcelain prosthesis is more difficult in this case. However, this technique can only be used for strict adherence to all phases. Finishing is very important
