The Technology Behind Same-Day Crowns
CEREC is the computer-aided design and manufacturing system that powers our same-day crown service. At Williamsburg Dental Health, we use CEREC to design and mill custom ceramic restorations right in our office, eliminating the need for messy impressions, temporary crowns, and multiple appointments.
The process starts with a 3D digital scan of your tooth. CEREC software creates a precise digital model and designs your restoration on screen. Our in-office milling unit then carves the crown, inlay, or onlay from a solid block of medical-grade ceramic in about 15 minutes.
The result is a durable, stain-resistant restoration that is color-matched to your natural teeth. CEREC is available at our Williamsburg and Marengo offices and is used for crowns, inlays, and onlays. It is one of the most advanced tools in our practice and a major convenience for patients who value their time.
Before CEREC, a crown or inlay typically required two visits separated by two to three weeks. The first visit involved a putty impression, a temporary restoration, and a wait while an outside lab fabricated the permanent piece. The second visit involved removing the temporary, checking the fit, and bonding the final restoration. CEREC compresses that entire process into a single appointment, saving you a trip to the office and eliminating the discomfort of a temporary crown.
The ceramic material used by CEREC is remarkably similar to natural tooth enamel in both strength and translucency. It resists staining, bonds securely to the prepared tooth, and distributes bite forces evenly. Because the restoration is designed from a digital scan rather than a physical impression, the fit is precise and the margins are tight, which reduces the risk of future decay around the edges.
CEREC is also an excellent option for patients who have lost a filling or crown unexpectedly. Rather than wearing a temporary for weeks while waiting for a lab, you can leave the office with a permanent, custom-fitted restoration the same day. Patients from Williamsburg, Marengo, and the surrounding Iowa County communities appreciate the convenience of finishing in a single appointment — and the peace of mind that comes with knowing the work is done right, right away.
