Single Crowns

The crown arrives with scan, verified shade, and complete prescription — ready to design.

TrazaLab structures every single crown case so the lab knows material, margin type, shade with photo reference, and abutment details — before opening a single file.

Crown Types

Four scenarios. One prescription.

Each crown type has different clinical requirements. TrazaLab captures the right fields for each one — so nothing is assumed.

Screw-Retained Implant Crown

Direct connection to implant through screw access hole. No cement risk. Retrievable for maintenance. Preferred in posterior zones and where tissue management allows.

97.2% implant crown survival 5yr

Pjetursson et al. 2018 — PMID 30328190

Cement-Retained Implant Crown

Custom abutment with cemented crown. Superior esthetics in anterior zone — no screw access hole visible. Requires careful margin placement to manage excess cement risk.

96.4% cemented implant crown 5yr

Sailer et al. 2015 — PMID 25842099

Tooth-Supported Crown

The most common restoration worldwide. Crown cemented or bonded over a prepared natural tooth. 93-95% survival at 5 years across all materials and indications.

97.1% metal-ceramic 5yr survival

Pjetursson et al. 2026 — PMID 41489982

Crown on Ti-Base

Hybrid approach: lab bonds ceramic crown to a titanium base. Combines the precision fit of a machined titanium interface with the esthetics of a full-ceramic crown. Screw-retained.

Precision fit + full-ceramic esthetics

Raigrodski et al. 2012 — PMID 22385693

Platform

This is how a crown case arrives at your lab

The surgeon fills out the crown prescription in TrazaLab. You receive the complete case: tooth number, material, shade with photo, margin type, abutment details, and all files attached.

No phone call. No WhatsApp audio. No guessing if shade A2 means the same thing to both of you. Everything structured, everything in one place.

Materials: what the data says

Not marketing claims. Published systematic review data comparing the four main single crown materials.

Material	Strength	Esthetics	Best For	5yr Survival
Monolithic Zirconia	900–1200 MPa	Very good	Posterior, bruxism	96.8%
Layered Zirconia	900–1200 MPa core	Excellent	Anterior esthetic zone	97.3%
E.max (Lithium Disilicate)	360–400 MPa	Superior	Anterior single crowns	98.5%
PFM	500–800 MPa	Good	Universal, proven	97.1%

Monolithic designs show significantly fewer ceramic fractures and chipping than veneered alternatives. In single crowns, monolithic lithium disilicate achieves the highest 5-year survival (98.5%), but material selection should always match the clinical scenario — strength for posterior, esthetics for anterior.

Outcomes

Clinical data, not promises

Every number below comes from a peer-reviewed systematic review. Click the source to verify on PubMed.

E.max monolithic 5yr

Monolithic lithium disilicate single crowns — highest reported 5-year survival for single crowns.

Pjetursson 2026 →

Monolithic zirconia 5yr

Monolithic densely-sintered zirconia single crowns — excellent survival with minimal chipping risk.

Pjetursson 2026 →

All-ceramic fracture rate

Ceramic fracture rate for all-ceramic single crowns at 5 years — primarily in veneered designs.

Digital Rx fields required

Every crown case in TrazaLab requires all 7 prescription fields — material, shade, margin, tooth, abutment, retention, and files.

Prescription Flow

The surgeon's prescription, step by step

Six structured fields. No free-text guessing. The surgeon selects, the lab receives — complete and validated.

Tooth Number Selection

Select the specific tooth from the odontogram. Universal numbering (#1-32) or FDI (11-48). No ambiguity about which tooth receives the crown.

Restoration Type

Crown, Inlay, or Onlay. Each type triggers different validation rules and required fields downstream in the prescription flow.

Implant Details (if applicable)

If the crown is implant-supported: implant system (Straumann, Nobel, Zimmer, etc.), abutment type (stock, custom, ti-base), and retention method (screw-retained or cemented).

Material Selection

Monolithic Zirconia, Layered Zirconia, E.max (Lithium Disilicate), PFM, or other. Each material has different minimum thickness requirements and clinical indications.

Shade with Photo Gate

Shade system (VITA Classical or 3D-Master) and specific shade selected. Photo gate: the surgeon must upload a shade reference photo before the case can be submitted. No more "A2... I think."

Margin Type + Prep Photo

Chamfer, Shoulder, or Knife Edge — selected explicitly, not assumed. Preparation photo required showing clear margins. The lab sees exactly what was prepared.

Quality Control

Validation before fabrication

8 crown-specific checks the lab runs before milling or pressing. Structured in TrazaLab so nothing is missed.

Scan Quality

Prep margins clear and fully captured — no artifacts

Full arch scan available for occlusal verification

Photography

Prep photo clear with visible margin line

Shade reference photo distinguishable and under calibrated light

Prescription

Material specified and appropriate for tooth location

Margin type documented (Chamfer / Shoulder / Knife Edge)

Shade selected with matching photo reference

Implant (if applicable)

Implant system confirmed with abutment type specified
