Partial Dentures | Removable Partial Denture Lab
HeZhan Dental Laboratory manufactures removable partial dentures (RPDs) for partial edentulism cases. We work with both traditional impressions and digital workflows to produce cast metal, flexible, and CAD/CAM frameworks with accurate fit and retention.
Our focus is on framework precision, material selection, and case communication—delivering partial dentures that seat correctly, engage abutment teeth properly, and provide long-term function.
Partial Denture Types We Produce
| Type | Description |
|---|---|
| Cast Metal Framework | Traditional cobalt-chromium RPDs with high strength and durability |
| Titanium Framework | Lightweight, biocompatible, CAD/CAM milled |
| PEEK Framework | Non-metal, aesthetic, CAD/CAM milled thermoplastic polymer |
| Flexible Partial Dentures | Acetal resin / Valplast, tooth-colored clasps for improved aesthetics |
| Acrylic Partial Dentures | Simple, economical option with wire clasps |
| Interim / Treatment Partials | Temporary prostheses during healing or treatment planning |
Framework Materials
| Material | Key Properties | Indications |
|---|---|---|
| Cobalt-Chromium (CoCr) | High strength, durable, cost-effective | Most RPD cases; standard choice for long-term use |
| Titanium | Strong, biocompatible, lightweight | Patients with metal allergies or preference for lighter frameworks |
| PEEK | Aesthetic, non-metal, CAD/CAM fabricated | Patients concerned about visible metal clasps; Class III Kennedy cases |
| Acetal Resin | Tooth-colored, flexible | Esthetic zones requiring invisible clasps; single-tooth replacements |
| Acrylic | Economical, simple fabrication | Temporary or low-cost treatment options |
Digital Workflow for Partial Dentures
We support both conventional and digital workflows for partial denture fabrication. Digital workflows have been shown to enhance patient comfort and work efficiency while achieving good fit.
Digital File Types We Accept
- STL files from intraoral scanners (iTero, Medit, Trios, etc.)
- Conventional impressions (alginate, PVS) for cast pouring and scanning
- Bite registrations
- Shade information
Digital Production Process
- Case Review: We check framework design, clasp placement, rest seat preparation, and survey line requirements before production
- Digital Framework Design: CAD design of framework on the digitally surveyed cast
- Framework Milling/Printing: Precision manufacturing using 5-axis milling or 3D printing
- Framework Try-in (if requested): Resin pattern try-in available for fit verification before final milling
- Teeth Setup: Acrylic teeth placement with appropriate shade and occlusion
- Processing and Finishing: Denture base processing, trimming, and polishing
- Fit Verification: Checked for fit, contact areas, occlusion, and path of insertion
Quality Control for Partial Dentures
Accuracy is critical for partial dentures. Even a small discrepancy in seating can result in open contacts, excessive pressure on abutment teeth, or rocking.
Our QC process includes:
- Scan Data Validation: Confirming impressions or scans accurately capture abutment teeth and soft tissue
- Framework Fit Check: Verifying framework seats completely on the model without rocking
- Clasp Retention Verification: Checking passive fit of retentive clasps on abutment teeth
- Occlusal Contact Preset: Adjusting contacts before delivery
- Path of Insertion Verification: Confirming unobstructed insertion and removal
Important Note for Dentists: For partial denture relines, we require an in situ impression with the denture seated in the mouth to accurately capture the true clinical position. Inaccurate impressions lead to poor fit, incorrect contacts, and occlusal discrepancies.
Implant System Compatibility
We manufacture implant-retained and implant-supported partial dentures compatible with all major implant systems. Please provide your implant system and attachment type (Locator, ERA, Conus, etc.) with your case submission.
What We Need From You
To start a case, please send:
- Impressions or STL files from intraoral scan
- Bite registration
- Shade requirements
- Framework material preference
- Framework design specifications (survey line, clasp placement, rest seats)
- Any specific clinical notes
We review each case within 24 hours and confirm feasibility before production begins.
Common Questions
Do you accept digital scans for partial dentures?
Yes. We accept STL files from all major intraoral scanners. Studies show digital workflows for PEEK RPDs achieve good fit and enhanced patient comfort.
What material do you recommend?
Depends on the case. Cast metal (CoCr) is the most common and cost-effective choice. PEEK or flexible partials are preferred for patients requesting improved aesthetics.
Can you match tooth shade?
Yes. Please provide shade information with your case submission.
Can you do a framework try-in?
Yes. Resin try-in frameworks are available for fit verification before final milling.
What are your lead times?
Cast metal frameworks: 5-7 working days. Complete partial dentures: 7-10 working days. Expedited options available on request.
