08 Feb Ceramic Overlay for the Cuspal Coverage
Performed by: Dr Naveed Anjum
Tooth no 36 presented with mesial chipping that was restored with Direct Composite filling before. Patient got that filling done 1 year before for the second time . He is looking for some treatment will last long enough. The old restoration was already wide and involving more than 2/3 of all cusps, so cusps coverage was planned. The treatment options considered were direct composite cusp coverage, Indirect ceramic overlay and full coverage crown. After discussing with patient about the mechanic properties, invasiveness, cost and long term outcome , Indirect ceramic overlay was selected.
Wedgeguard were placed to avoid the iatrogenic damage to adjacent teeth. Approximal reduction done after the approval reduction. Shoulder margins are created for the Lithium Disilicate Over Lay.
