USING COMPOSITE RESIN 2

USING COMPOSITE RESIN 2

1. POSTERIOR CLASS I

   • Do not remove unaffected tooth tissue
   • Unsupported enamel can be left
   • Do not bevel enamel edges
   • LA, Shade, rubber dam

2. OUTLINE FORM - access caries

   • Remove from ADJ
   • Place comp in small increments and cure for 30 secs
   • each increment only touches 1 wall of prep
   • final increment and contour shape
   • Remove rubber dam and check occlusion
   • Finish and polish - remove oxygen inhibited layer

3. CLASS II

   • OUTLINE FORM - access caries
   • Lesions generally saucer shaped
   • Contact areas must be cleared
   • Same as before - matrix, fill in increments etc
   • Run probe round marginal edge to ensure no overhangs

4. CLASS V

   • Same as before - LA, shade rubber dam etc
   • OUTLINE FORM - gain access and remove decalcified enamel
     • bevel enamel edges and line as appropriate
   • Contour, finish and polish

5. CLINICAL HANDLING

   • Don not condense like amalgam
   • where possible use composite instruments
