Raytops Post Core Dental
At Raytops, we design and craft high-quality post and core restorations. This process involves placing a small rod, known as the post, into the prepared root canal, while the core material is used to rebuild the decayed area. Together, the post and core provide essential stability and strength to support a dental crown or bridge.
While implant systems offer an alternative solution, they are often more expensive and require a longer treatment time. Raytops’ post and core restorations are a reliable and cost-effective choice for restoring function and maintaining oral health.

Choosing the right post & core material impacts not just crown fit — but long-term success, esthetic outcome, and tissue health. At Raytops, we guide our partners based on prep, position, and prosthetic plan.
🔍 Material Comparison Chart
| Feature | Metal Post & Core | Zirconia Post & Core |
|---|---|---|
| Flexural Strength | Very High (>800 MPa, depending on alloy) | High (~900–1200 MPa) |
| Esthetics | Low – may shadow or reflect through crown | High – tooth-colored, ideal under ceramics |
| Biocompatibility | Moderate – some alloys may cause reaction | Excellent – inert, gingiva-friendly |
| Chairside Adjustability | Easy to trim, grind, polish | Limited – requires diamond tools, more brittle |
| Indications | Molars, deep preps, high-load zones | Anterior teeth, esthetic crowns, metal allergies |
| Workflow | Cast or milled from wax-up/model | Designed & milled from scan (CAD/CAM) |
| Cementation Compatibility | Conventional cements (GI, RMGI) | Adhesive cementation recommended |
🧩 Lab-Guided Selection Advice
If the prep is deep and occlusal load is high (molar): Go metal. It’s more forgiving, especially if margins are subgingival or ferrule is minimal.
If esthetics matter (anterior, premolar): Choose zirconia — especially when planning all-ceramic crowns. It blends with core and supports better gingival harmony.
If patient has known metal sensitivity: Go zirconia. We track material batches and can supply documentation for patient records.
If you’ll need to adjust intraorally: Metal is faster and more forgiving chairside — especially in multi-unit preps.
🧠 Lab Tip: Let us know the intended crown material (PFM, zirconia, lithium disilicate). We’ll design the core for optimal ferrule exposure and emergence profile to suit it.
Dental lab Digital Workflow
Precision Starts in the Canal – Raytops’ Workflow for Post & Core Restorations
Post & Core restorations demand more than just a fit — they require a workflow that respects root anatomy, crown strategy, and cement compatibility. At Raytops, we’ve built a canal-to-core process that eliminates guesswork and maximizes retention.
🧩 Our Digital Workflow, Step by Step
1. Data Collection & Prep Analysis
Accept STL/PLY files from 3Shape, iTero, Medit, or traditional impressions
Evaluate canal visibility, taper, depth, and ferrule height
Request intraoral photos for margin zone if gingival coverage is tight
2. Post & Core CAD Design
Canal geometry modeled in 3D for passive fit, retention grooves, and venting
Core morphology adapted for planned crown type (PFM, full-zirconia, E.Max)
Margin design adapted to your prep: shoulder, chamfer, or beveled
3. Material-Specific CAM Processing
Metal Post & Core: Wax-up → Press or mill from alloy based on span/load
Zirconia Post & Core: Milled from high-density blocks with precision pin fit
All post stems smoothed, vented, and edge-rounded to reduce stress points
4. Fit & Finish Check
Passive-fit verified on 3D printed internal root analog (lab-printed)
Core contours checked against planned emergence profile
Each unit polished and labeled with material type, patient ID, and quadrant
✅ Raytops Lab Differentiators
Root-Focused CAD Knowledge
Our designers are trained to build retention not just on core shape, but on canal taper behavior and cement flow.Margin Integrity Guarantee
Cores are finished to <30μm tolerance at margin, reducing crown misfit.Post-Ferrule Matching
We match core emergence to your prep ferrule — ensuring full coverage without crown overhangs.Cement Compatibility Mapping
We can pre-define post surface roughness or vent channels based on adhesive system provided.
🧠 Lab Tip: If you’re combining crown + post/core in one case, we recommend sending both scans upfront. We’ll co-design core emergence and crown margin for a seamless transition — with less chairside grinding.
Customization - Product Fits Reference
Customization That Supports Structure – Post & Core Design Built Around the Tooth
Every post & core case is a structural equation. It’s not just about fitting inside the canal — it’s about supporting a crown, matching the prep, and restoring bite forces. At Raytops, we customize every post & core based on what you prep, what you plan, and what your patient needs.
🦷 Canal-Adaptive Post Geometry
Taper Matching:
Each post is designed to your canal prep angle and verified against scan or model taper — reducing seating pressure and dislodgement risk.Length Control:
Post length adapted based on tooth length, remaining structure, and radiographic reference (if provided).Stress Zone Modification:
Rounded shoulders and venting grooves can be added for cases with known fracture risk (e.g., thin roots, history of post failure).
📐 Crown-Driven Core Customization
Ferrule Height Mapping:
Core emergence built to match shoulder/chamfer line, ensuring consistent 360° support for your crown margin.Anatomical Support Zones:
We reinforce core volume where crown connectors or pontic loads will apply (especially for bridges or splinted restorations).Cementation Flow Channels:
Optional internal relief and vent lines for better cement escape — especially useful in tight-fitting zirconia post cases.
🧩 Your Preferences, Remembered & Applied
Material-Specific Defaults:
We store whether you prefer high-opacity zirconia or standard alloy for post cases by zone (anterior/posterior).Margin Style Storage:
If your clinic consistently preps shoulder bevels or deep chamfers, we match that across cases.CAD/CAM Integration with Your Lab Team:
If you outsource crown work, we can align post/core designs with your crown lab’s emergence profile and contact zones.
🧠 Lab Tip: Let us know if you need diagnostic wax-up or crown stumps first. We can co-design core shape to follow future restoration path — especially useful for high-value anterior teeth or full-arch sequencing.
Clinical Applications & Indications
When Is a Post & Core the Right Choice? And How We Help Make It Work.
Post & Core restorations aren’t for every RCT case — but when used correctly, they can rescue compromised structure and prevent future failure. At Raytops, we assist clinicians and labs by matching post-core strategy to actual prep and occlusal needs.
🧩 Common Indications We Support
| Clinical Scenario | Recommended Post Type | Lab Considerations |
|---|---|---|
| Severely broken-down posterior with deep RCT | Metal Post & Core | Casted design with long passive stem, reinforced core bulks |
| Anterior esthetic case with thin labial walls | Zirconia Post & Core | Custom-tapered post, reduced light-blocking core |
| Lack of ferrule height on remaining structure | Metal Post & Core | Core flared to maximize prep contact; request gingival photos |
| Metal-sensitive or cosmetic-sensitive patient | Zirconia Post & Core | Biocompatible, shade-matched, digitally milled |
| Bridge abutment with post-retained terminal | Metal Post & Core | Core reinforced at connector zone, margin thickening |
| Temporary post to hold crown in provisional phase | Optional (resin/metal) | Request if temporary crown prep is pre-designed |
🔎 Risk Zones We Help You Control
Canal taper mismatch → We simulate insertion digitally and flag post binding risk
No or minimal ferrule → We adapt core height and shape to avoid crown rocking
Over-extended post risk → We base post length on STL depth + crown planning; alert if near apex
High bite force patient → We switch to bulkier core, shorter post, or suggest cast metal base
🤝 Lab-Coordinated Adjustments in Complex Cases
Multiple post-core restorations across arch → We stage seat order, sync margin lines, and contact emergence
Combo crown + post in same scan → We co-design crown margin to fit final core emergence
Esthetic zone / thin tissue cases → We soften emergence angle to prevent shine-through or core show
Post-over-core revision cases → We support reverse-scan & replica-fit from removed failed post
🧠 Lab Tip: For borderline cases (deep post, thin root, no ferrule), let us know your prep rationale. We’ll flag risk, suggest options, and adjust before it becomes a chairside problem.
Product & Material Selection Guide
Choosing the Right Post & Core – A Practical Guide for Labs and Clinicians
Not every endo-treated tooth needs a post. But when a post & core is required, the right material and design can mean the difference between long-term success and repeated chairside frustration.
Here’s how we help you choose smart, based on case type and restoration plan:
🔍 Decision Guide – Do You Need a Post & Core?
| Condition | Recommended Action |
|---|---|
| ≥ 2mm ferrule, strong remaining walls | Crown only – no post needed |
| Thin remaining walls, deep canal, no ferrule | Post & Core – consider cast metal |
| Esthetic zone, visible prep, full ceramic crown planned | Zirconia Post & Core preferred |
| Wide, short canal with minimal resistance | Post & Core – reinforce with passive taper and long stem |
| Short clinical crown, patient grinds at night | Metal Post & Core – high strength base |
| Multiple abutments with crown-bridge plan | Coordinate post-core with final bridge path |
⚙️ Material Selection Reference
| Factor | Choose Metal | Choose Zirconia |
|---|---|---|
| Functional loading (molars, premolars) | ✅ Best under compressive force | ⚠ Only if esthetic override required |
| Esthetics / translucency needed | ❌ May shadow through ceramic | ✅ High translucency, blends with crown |
| Patient metal sensitivity | ⚠ Use high-noble alloy or avoid | ✅ Biocompatible and inert |
| Core shape complexity / splinting | ✅ Easy to reinforce, adjustable | ⚠ More fragile under connector stress |
| Fast chairside adjustment needed | ✅ Quick polish & trim | ❌ Needs slow-speed, risk of fracture |
| Cement used: conventional | ✅ Compatible (GI/RMGI) | ⚠ Requires resin bonding |

Frequently Asked Questions
Frequently Asked Questions – Post & Core Workflow with Raytops
❓ What type of impressions or scans do you accept for post & core?
We accept STL, PLY, and OBJ files from all major intraoral scanners. For analog submissions, a clean model with visible canal path and ferrule is required. For deeper canal cases, a putty pickup of the post space is recommended.
❓ Can you help me decide between zirconia and metal?
We do not diagnose or prescribe, but we’ll advise based on your prep, photo, scan, and intended crown material. We often flag esthetic or strength-based risks and suggest options with pros/cons.
❓ How do you design the post length?
Post length is determined by canal scan or model depth and adjusted to avoid apex contact. We maintain passive fit zones and flag any excessive depth concern.
❓ Do you polish or roughen the post surface?
Yes — zirconia posts are delivered with mild surface texture for bonding. Metal posts can be delivered polished or micro-roughened based on your cementation preference.
❓ Can you deliver the post-core with the crown?
Absolutely. If you submit both post-core and crown prep scans together, we design them in tandem — ensuring emergence, ferrule height, and margin continuity.
❓ Do you provide seating models?
Yes, on request. We can deliver 3D printed root analogs for passive-fit verification, or stone models for chairside guidance.
❓ What’s your typical turnaround time?
Standard turnaround is:
Metal Post & Core: 4–5 working days
Zirconia Post & Core: 5–7 working days
Rush cases are available — let us know your deadline.
❓ What if the post doesn’t fit?
If the post doesn’t seat due to lab-side fit issue (not prep error), we remake at no charge. We request return of original to assess insertion resistance and adjust design protocol.
🧠 Lab Tip: Always include intraoral photos if prep margins or canal paths are not well captured — we’ll flag any concerns before fabrication starts.
Trends & Future Outlook in Implant Restorations
