As a dental practice, your work can involve providing dentures, crowns, bridges, and other prosthetics for your patients. Providing high-quality prosthetics requires accurate impressions and precision in design and manufacturing. Sometimes the prosthetics don’t fit properly and require remakes or adjustments. Here are a few ways a dental lab handles such remakes and adjustments:
Case Documentation Review
Remakes and adjustments require detailed case documentation and effective communication. The dental lab reviews the original case details to analyze patient prescriptions, impressions, scans, and other details. If the initial impressions were not taken properly, the lab can provide additional resources to reduce the need for future remakes and adjustments. The resources include selecting the right impression materials and trays and how to avoid common impression errors. Labs also establish feedback loops involving regular communication with the dentist to explore the issue further.
Case documentation and clear feedback loops help the lab understand all instructions and requirements for the remakes and modifications. The documentation also shows details, such as the fit, shade, and functionality. Proper review of the original documentation and remake instructions allows the lab to identify specific corrections needed for the prosthetic. If your practice uses digital scanners and other software systems, the lab can adjust the data instead of starting the process from scratch. Information stored in digital systems allows for quicker remakes and adjustments with minimal resource waste.
CAD and CAM Modifications
Labs use digital impressions from the dentist to identify and minimize errors for accurate remakes. If the restoration is created using traditional dental molds, the lab can switch to computer-aided design, CAD, and computer-aided manufacturing, CAM systems. CAD and CAM systems use intraoral scanners to take accurate digital impressions of the patient’s teeth and gums. The digital impressions help to create accurate 3D images and representations of the patient’s teeth. Accurate impressions allow lab technicians to adjust the shape, fit, and bite of the prosthetics to match the patient’s needs.
All adjustments for fit, color, and aesthetics are achieved digitally. Simulations and adjustments are also done digitally to provide accurate outcomes of the procedure. Dentists can visualize the restoration outcomes before manufacturing begins, reducing the likelihood of improper fits, alignments, and aesthetics. After designing using CAD systems, the data is sent to CAM systems featuring milling machines and 3D printers for fabrication. The machines can fabricate dental prosthetics with extreme precision using zirconia, composite blocks, and other materials. CAD and CAM systems also enhance automation and provide consistent quality production.

Quality Control Checks
Labs hire skilled technicians trained in complex restorations and different materials and techniques. They use advanced technology for precision and have rigorous quality control processes featuring internal inspections and material checks. Before the prosthetics are sent back to your office, they undergo a thorough inspection to meet all specifications provided. Labs also work with high-quality zirconia, porcelain, alloys, and other materials to deliver durable products. They also offer expert material handling and test the fit and occlusion.
Skilled lab technicians can identify what went wrong with the initial prosthetic and collaborate with your practice to address underlying dental issues. They can adjust design files to improve fit, appearance, and final construction. Labs also handle polishing, contouring, shading, and other reworking requirements. Other quality control measures include having a streamlined workflow, recordkeeping, and collecting feedback. Outsourced labs also invest in state-of-the-art technology, adapt to new techniques, and perform thorough inspections before shipping.
