Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

, in this studythe investigator will compare between ready-made zirconia crowns and Computer-aided design and Computer-aided manufacturing (CAD/CAM) polymethyl methacrylate (PMMA) crowns to overcome the disadvantages of ready-made zirconia crowns.

ready made zirconia

the selected tooth will receive ready made zirconia crown

Group Type EXPERIMENTAL

preparation of the tooth to receive ready made zirconia crown

Intervention Type OTHER

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

Group Type EXPERIMENTAL

preparation of the tooth to receive CAD CAM PMMA custom made crown

Intervention Type OTHER

* 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 .
