CAD CAM
Pearl City, HI
Walk into a modern pediatric dental office today, and you may notice something that looks like a miniature 3D scanner sitting on a cart near the treatment chair. That device, along with the milling unit elsewhere in the office, is part of a CAD/CAM system, a technology that has changed how dental restorations are designed and delivered. For children and their parents, the most visible benefit is straightforward: a crown, inlay, or onlay that once required two or three appointments can now often be completed in a single visit.
What CAD/CAM Stands For
CAD/CAM is an abbreviation for Computer-Aided Design and Computer-Aided Manufacturing. In dentistry, CAD refers to the process of digitally designing a restoration using specialized software, while CAM refers to the automated milling or fabrication of that restoration from a solid block of material. These two steps, design and production, happen in sequence and are connected through the digital file they share. Together, they eliminate much of the manual labor and extended wait time associated with traditional crown fabrication.
Traditional restorations required a dentist to take a physical impression using putty-like material, ship it to an outside laboratory, and wait one to three weeks for the finished crown to return. During that time, patients wore a temporary restoration that was more fragile and less precisely fitted than the final product. For children especially, managing a temporary crown between appointments adds stress for both the child and the family. CAD/CAM replaces nearly every step in that process with a faster, more accurate digital workflow.
How the Process Works From Start to Finish
The process begins after the tooth has been prepared. Instead of pressing an impression tray into the mouth, our dental team uses a small handheld intraoral scanner to capture a precise three-dimensional image of the prepared tooth, the surrounding teeth, and the bite. This scan takes only a few minutes and is far more comfortable than traditional impressions, which is a meaningful advantage when treating younger patients who may already feel nervous in the dental chair.
The scan is sent directly to CAD software, where our doctors or a trained team member designs the restoration. The software can suggest an initial shape based on surrounding tooth anatomy, which is then reviewed and refined on screen. Margins, contours, contact points, and biting surfaces can all be adjusted before any material is touched. Once the design is approved, it is transmitted to a milling unit that carves the restoration from a solid ceramic or composite block, typically in 10 to 20 minutes. The finished piece is then adjusted for fit, polished, and bonded into place during the same appointment. From preparation to placement, the entire process can often be completed in roughly two hours.
Materials Used in CAD/CAM Dentistry
The quality of a CAD/CAM restoration depends significantly on the material being milled. Our doctors select the most appropriate option based on the tooth's location, the child's bite, and how much longer a primary tooth is expected to remain before natural shedding.
Lithium disilicate ceramic offers excellent translucency that closely mimics natural enamel, making it well-suited for visible teeth where aesthetics matter to older children and teenagers. It also provides reliable strength for most restoration types.
Zirconia is valued for its exceptional durability and performs well under the heavy chewing forces of back teeth. It is one of the hardest ceramic materials used in dentistry, and newer formulations have improved its natural appearance while maintaining that strength. For posterior primary teeth that need to last several more years, zirconia is often an excellent choice.
Hybrid composite materials, which combine ceramic and resin, are also available and offer a slightly more flexible feel that can be gentler on opposing teeth. As dental material science advances, the options available within CAD/CAM systems continue to grow.
Accuracy and Fit
A well-fitted restoration is especially important in pediatric dentistry, where a poorly fitting crown can contribute to sensitivity, bite problems, or early failure in a tooth that still has years of function ahead of it. CAD/CAM restorations consistently demonstrate accuracy that meets or exceeds what is achievable through conventional laboratory methods.
Digital impressions eliminate the distortion that can occur when traditional impression materials shift as they set. Software-guided design reduces variability in margin placement and contour. Milling machines operate with precision tolerances measured in microns. The result is a restoration that fits closely and integrates well with the surrounding bite and adjacent teeth.
This precision also benefits the bonding process. A well-fitted crown requires less cement to fill gaps, reducing the risk of marginal leakage over time. Children tend to adjust more comfortably to a well-fitted final restoration than to a temporary that may shift or feel unfamiliar during the weeks between appointments.
Benefits Beyond Convenience
The single-visit aspect of CAD/CAM dentistry receives the most attention, but it is not the only advantage worth noting. Eliminating the temporary crown removes one of the more common sources of post-treatment complications. Temporaries can loosen, fracture, or allow sensitivity to develop while the permanent restoration is being fabricated elsewhere. When the final restoration is placed the same day, that window of risk is removed entirely.
Fewer appointments also matter more in pediatric care than in almost any other dental specialty. Every trip to the dental office asks something of a child, whether that means managing nerves, missing school, or a parent rearranging work schedules. Completing care in one visit rather than two reduces that burden meaningfully. For children who experience anxiety around dental treatment, fewer cumulative appointments can make a lasting difference in how they relate to dental care as they grow.
Digital records stored in the CAD software also provide a useful reference. If a restoration needs to be replaced or adjusted in the future, the original design data can often be retrieved as a starting point, saving time at subsequent visits.
Ask Our Doctors About Same-Day Restorations
If your child has a tooth that needs a crown, inlay, or onlay, same-day CAD/CAM dentistry may be an excellent option. At Oahu Pediatric Dentistry, our doctors use advanced digital technology to design and deliver dental restorations with precision and efficiency, often in a single appointment.
