COMPOSITE RESIN
1 resin matrix, filler, silane coupling agent
2 Non adhesive material - requires bonding agent
3 Hydrophobic, photophillic
4 polymerisation shrinkage
5 place in small increments - only cures at 2mm
5.1 pts can be hypersenitive to products
6 ADVANTAGES
6.1 Wear and compressive resistance matches tooth substance
6.2 command set - light cure
6.3 good aesthetics
6.4 more conservative of tooth tissue
7 DISADVANTAGES
7.1 polymerisation shrinkage
7.2 moisture control essential
7.3 technique of placement
7.3.1 2mm increments - time consuming
8 TECHNIQUES TO OVERCOME POLYMERISATION
8.1 keep field as dry as poss - will shrink away from water
8.2 ramped output from light source
8.3 place in oblique increments
8.4 direct light to gingival floor
9 CLINICAL INDICATIONS
9.1 Anterior - classIII, IV, V
9.2 Posterior - Class I, II, V
9.3 Deciduous restorations
10 ANTERIOR - outline form, access from palatal/lingual aspect
10.1 keep prep as min as possible - use small round bur
10.2 Remove caries from ADJ and as much stained dentine - better aesthetics
10.3 Bevel enamel edges for larger surface area of bonding
10.4 Apply comp in increments using clear matrix and cure for 30secs
11 CLINICAL HANDLING OF COMP IN ANT TEETH
