1. The occlusal margins of a composite restoration have begun to break down.  There is no radiographic evidence that decay has spread far beyond the surface.

 

 

 

 

2. A Fissurotomy bur (SSWhite) removes all decay and questionable tooth material.

 

 

 

 

3. The perimeter preparation is examined for any remaining decay.

 

 

 

 

4. Air abrasion increases the surface roughness and bondability of the cavity.

 

 

 

 

5. Beautibond (Shofu) 7th generation adhesive is applied to the cavity preparation.

 

 

 

 

6. The adhesive is thoroughly air-dried.

 

 

 

 

7. A brief 3-5 seconds of LED light curing is all that is required for the adhesive.

 

 

 

 

8. Beautifil Flow Plus (Shofu), indicated for posterior occlusal surfaces, is used to repair the perimeter cavity and light cured.

 

 

 

 

9. The completed Perimeter technique offers a restoration that will serve the patient effectively for many years.
