Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
ready made zirconia
the selected tooth will receive ready made zirconia crown
preparation of the tooth to receive ready made zirconia crown
Occlusal reduction 1 to 2 mm using flame bur . Open the interproximal contacts. The tooth should be reduced circumferentially by approximately 0.5-1.5mm . The preparation margin should be carefully extended and refined to a feather-edge approximately 1-2mm subgingivally .
Crown size will be determined using try in kit .
pmma crown
the selected tooth will receive cad cam custom made pmma crown
preparation of the tooth to receive CAD CAM PMMA custom made crown
* Open the interproximal contacts .
* The tooth should be reduced circumferentially by approximately 0.5-1mm .
* The preparation margin should be carefully extended and refined to a feather- edge approximately 1-2mm subgingivally .
* Rubber base impression will be taken by BMS additional silicone kit to the prepared tooth and will be sent to the laboratory to be scanned and to design the crown .
* The final crown will be cemented using glass ionomer cement .
