Preparation of a Typical Dental Crown
A typical dental crown is prepared in two dental visits. It involves the following steps:
- During the first visit, the dentist will perform an oral and digital X-ray examination of your affected tooth and its surrounding gums.
- The affected tooth is shaped to provide a perfect structure to fit the dental crown over it.
- An impression of the prepared tooth is created using a paste or a putty. It is then sent to a technician to prepare a permanent crown for it.
- Till the time, a permanent crown is prepared, a temporary crown is attached on the damaged tooth using temporary cement or temporary glue.
- You may visit your dentist for a second visit after two-three weeks. During this period a permanent crown is prepared.
- During the second visit, the temporary crown is removed and replaced with a permanent crown.
- Before attachment of a permanent crown, certain adjustments are made to perfectly fit it over the damaged tooth.

What is Cerec?
Cerec is a high-tech dental device which prepares a dental crown. It is the fastest method for preparation of a permanent crown. A Cerec prepares a permanent crown during the first visit of a patient to a dentist’s clinic.
It is by far considered one of the best methods for a dental crown preparation, as it does not require multiple visits by the patient to the clinic. During the first visit, the dentist analyzes your affected tooth and cements the permanent crown on your tooth. It does not require any attachment of a temporary tooth as the permanent tooth is prepared in few hours only.
A Cerec crown is prepared using computer aided design (CAD) or computer aided manufacturing (CAM) technology. It is a digital mapping technology which takes a computerized image of the inner region of your mouth and the affected tooth. It involves a detailed and accurate technique for the preparation of a tooth crown as compared to manual methods of dental crown preparation.
Method of Cerec Crown Preparation
A Cerec crown is one of the fastest and easiest methods for preparation of a dental crown. It involves the following steps:
- The dentist may carry out oral and digital X-rays to examine your damaged tooth and determine if a dental crown is required for the treatment of the damaged tooth.
- The dentists will shave your tooth to give it an ideal structure, which allows perfect fitting of a Cerec crown over it.
- An intraoral camera is used to prepare a digital image or impression of your affected tooth. This is carried out using a device known as wand.
- On the basis of a digital image, Cerec software prepares a virtual 3D-model of your damaged tooth. This model is used by your dentist to construct tooth restoration on the screen. Then, the finished construction is wirelessly transferred to an in-office milling machine.
- The Cerec device carries out the milling or manufacturing of the Cerec crown using high-grade ceramic, plaque resistant material.
- Your dentist may add certain finishing touches to your tooth restoration and he or she will cement the Cerec crown on your affected tooth. In rare cases, certain fitting adjustments are required to attach the Cerec crown over the tooth.
This allows the preparation of a perfectly-sized, shaped and shaded Cerec crown in its optimal form and function.
