Making a crown includes four major steps: design, tooth preparation, mold taking, fitting and cementation, which usually takes about 1 week. 1. Design: The practitioner first selects a suitable restoration according to the gap and shape of the tooth, as well as its relationship with the opposite jaw and neighboring teeth. 2. Tooth preparation: The teeth are ground down to the appropriate thickness according to the choice of restoration. 3. Modeling: A model of the teeth in the mouth is reproduced using materials such as silicone rubber or alginate, and then sent to a fabrication shop for processing. The above steps usually take about 1 hour, and the fabrication process usually takes about 1 week. 4. Trying on and bonding: The crowns are tried on and adjusted in the mouth to observe the fit and to stabilize the occlusion comfortably, and then permanently bonded with a bonding agent. It should be noted that with the advancement of technology, some well-equipped units have chairside processing system, which can be completed instantly on the same day. It is recommended to visit the dental department of a regular hospital.
