Patients may need a crown for a variety of reasons. Common reasons we might place a crown include fixing a fractured tooth, restoring a tooth with a large cavity, or protecting a tooth after a root canal. Crowns are used when a large part of the tooth is missing or damaged—which replaces the missing tooth structure. Patients undergo the procedure and receive a brand new crown in just one visit. That’s because Off Island Dental offers Planmeca, an innovative dental imaging technology that allows our dentists to construct your crown right here in our office. From start to finish, the procedure takes about two hours. Also, no more messy dental impressions. Because Planmeca uses computer-aided design, or CAD technology, Dr. Langehans scans the tooth and uses computer software to design your new crown.
