Quality Control for Dental Restorations

HeZhan Dental Laboratory checks each dental case at key production stages to support accurate fit, proper function, natural aesthetics, and consistent restoration quality.

From file review to final inspection, our quality control process helps reduce communication errors, production issues, unnecessary adjustments, and remake risks for global dental clients.

Why Quality Control Matters

Dental restorations require accuracy at every stage. Small issues in file information, material selection, margin design, contact, occlusion, shade, or finishing can affect the final result.

At HeZhan Dental Laboratory, quality control is not only a final check before shipping. It is part of the whole production workflow, from case review and material confirmation to technician inspection and final delivery preparation.

Quality Checks at Key Production Stages

Case and File Review

Before production, we review case instructions, STL files, scan data, shade information, margin details, occlusion records, implant components, and special requirements.

Clear and complete case information helps improve production accuracy and reduce delays before manufacturing begins.

Material Confirmation

Materials are selected according to the restoration type, client requirements, shade needs, strength expectations, and case conditions.

We work with recognized dental materials and digital systems to support stable restoration results across different case types.

Design and Production Check

During design and production, technicians check anatomy, contact, occlusion, margin fit, framework structure, and restoration requirements based on the client’s instructions.

For digital cases, CAD/CAM design and case review help support better consistency before the restoration moves through production.

Fit, Function, and Aesthetic Review

Each case is checked for fit, function, contact, shade, shape, surface texture, and overall appearance according to the client’s requirements.

Our goal is to support restorations with accurate fit, proper function, natural aesthetics, and stable quality from case to case.

Final Inspection Before Delivery

Before packing and delivery, each case receives a final inspection to confirm finishing details, case information, and delivery readiness.

This final check helps ensure that the completed restoration matches the submitted requirements before it is prepared for international delivery.

What We Check Before Delivery

Fit: margin, seating, internal fit, and model fit.

Function: occlusion, contact, and bite relationship.

Aesthetics: shade, shape, translucency, surface texture, and overall appearance.

Material: material type, restoration indication, and case requirements.

Case Details: client instructions, shade notes, special requirements, and delivery information.

Finishing: polishing, contour, surface smoothness, and final surface details.

Packing: case protection, labeling, and delivery preparation.

Quality Control by Restoration Type

Zirconia Crowns and Bridges

For zirconia crowns and bridges, we check margin fit, contact, occlusion, anatomy, shade, surface finishing, and bridge framework strength.

E.max Restorations

For E.max restorations, we focus on shade, translucency, contour, bonding surface, marginal accuracy, and aesthetic requirements.

Implant Restorations

For implant restorations, we review implant component information, scan body data, emergence profile, occlusion, screw access, and restoration fit.

Removable Dentures

For removable dentures, we check fit, bite relationship, tooth arrangement, base finishing, comfort-related design details, and client instructions.

Surgical Guides

For surgical guides, we review digital planning requirements, guide fit, sleeve position, case data, and production accuracy before delivery.

Connected with Our Digital Workflow

Quality control starts before production.

By reviewing digital files, case instructions, material requirements, and technical details early, HeZhan helps reduce communication errors and unnecessary adjustments later in the process.

Our digital workflow supports STL-based cases, CAD/CAM design, production coordination, quality checks, and international delivery for dental labs, clinics, distributors, and dental service providers worldwide.

Materials and Systems Support Stable Quality

HeZhan works with recognized dental materials and digital systems to support stable restoration results across different case types.

Materials and systems may include 3Shape, IPS e.max, VITA, Noritake, SHOFU, Argen, Aidite, and Ivoclar Vivadent.

These materials and systems help support different restoration needs, including crowns, bridges, implant restorations, removable prosthetics, frameworks, surgical guides, clear aligners, and digital dental cases.

Remake Support and Case Communication

If a case requires adjustment or review, our team communicates with the client to understand the issue, review case information, and provide practical support based on product type, material, and case conditions.

For selected restoration types, warranty support may be available depending on product category, material, and agreed case conditions.
