Summary

The study will evaluate the clinical performance and both patient and parent satisfaction of 3d printed crowns versus prefabricated Stainless-steel crowns (SSCs) in compromised first permanent molars

Conditions

  • 3D Printed Crowns

Interventions

PROCEDURE

3D printed crown

Reduction will be performed on the occlusal surface using a flame stone or a wheel stone, to perform occlusal clearance by 1 mm. Reduction will be performed by 1 mm on the mesial, distal, buccal and lingual surfaces of the tooth. Impression for the preparation will be taken using putty and light poly vinyl siloxane material. Temporary crown will be placed above the preparation as temporisation.The impression will be sent to the lab .The preparation will be optically scanned in the lab and the restoration will be digitally designed using computer designing software.The crown will be printed using 3D printer using hybrid resin(micro-filled hybrid material) material.The 3d printed crown is cemented with resin cement.

PROCEDURE

stanless steel crown

The occlusal surface of the tooth should be reduced by about 1.5 mm, maintaining its occlusal contour or until the tooth is out of occlusion with adequate room to fit a crown.Proximally, tooth reduction will be made through the mesial and distal contact areas, then roundation of line angles to avoid the creation of ledges or steps.The crown selection will be done by trial and error or by measuring the mesiodistal dimension of the tooth space with dividers. It can also be helpful to measure the dimension of the contralateral tooth. A correctly fitting crown should snap or click at try in.
