Semi direct Composite Indirect Composite Direct Composite -fabricated intraorally - photo thermic curing in small furnace -cementation -restoration is fabricated on a jypsum model. -Cured in small furnace. -cementation. Intraorally, 1 visit. -incremental technique. -sandwich technique. technique limited number of teeth with favorable mouth access . serial large restorations with limited cuspal coverage. -small to medium class I and II cavities. -class III, IV and V. indication -better wear resistance. -better dimensional stability . -better marginal adaptation. - Single visit. -better esthetics. -more effective contact points. -requires less clinical time. -Satisfied properties if applied carefully. advantages -multiple extra oral steps -affected by the type of cement used. -multiple visits. -higher costs. -affected by the type of cement used. Polymerization shrinkage. Marginal leakage. Postoperative sensitivity. disadvantage
