Cement-Retained Implant PFM Crown

Cement-retained implant PFM (Porcelain-Fused-to-Metal) crown is fixed onto custom or stock titanium abutments with dental cement. Together with screw-retained crowns, it is one of the two mainstream options for single implant restorations. While monolithic zirconia implant crowns gain popularity, cement-retained PFM crowns remain widely prescribed for posterior sites and cases with unfavorable implant angulation, thanks to reliable strength and competitive pricing.

Structure

It consists of a metal substructure layered with porcelain veneer. Common alloys include cobalt-chrome and noble palladium alloys, compatible with most major implant systems such as Megagen, Zimmer and Neodent.

Key Clinical Benefits

Intact occlusal table. Without a screw access hole, natural occlusal anatomy, guidance and occlusal adjustment are easier to achieve, ideal for high-load molar areas.

Corrects poor implant angulation. Custom abutments can compensate tilted implant position, avoiding visible screw channels in high-esthetic smile zones.

Better passive fit, less lateral stress transferred to the implant fixture.

Cost-effective, suitable for patients with budget limitations, especially popular in Africa and Latin America.

Limitations & Risks

Residual cement is the primary hazard. Excess cement left subgingivally causes peri-implant mucositis and bone loss. Supragingival margins are strongly recommended for easy cement cleanup.

Poor retrievability. It is difficult to remove the crown non-destructively for future maintenance, with risk of porcelain chipping.

Esthetic compromise: metal margin may show a dark line at gingival level; porcelain chipping risk exists for heavy bruxers.

Cement-Retained VS Screw-Retained

Cement-retained: full occlusal anatomy, fixes angulation issues; risk of cement remnant, hard to remove.

Screw-retained: retrievable for easy maintenance, no cement risk; occlusal hole compromises anatomy and esthetics.

Global Market Trend

In North America, zirconia implant crowns are rising, yet PFM cement-retained crowns are still preferred for many budget posterior cases. High local lab costs drive outsourcing to Chinese dental labs. In emerging markets like Cameroon, cement-retained PFM implant crowns are the first choice for posterior implants due to affordable cost and sufficient strength. Most cases now pair with CAD/CAM custom titanium abutments for superior marginal precision.

Scanning & Prescription Notes

Complete margin, gingival contour and occlusal scan data are required. We suggest supragingival margin design. Please specify alloy type, margin level and occlusal clearance on your prescription. Indications: single posterior implant, tilted implant axis, cases wanting no occlusal screw hole. Caution for deep subgingival margins, severe bruxism, metal allergy and thin-gingival high-esthetic anterior sites.

Our lab fabricates cement-retained implant PFM crowns compatible with all major intraoral scanners and implant platforms. Cobalt-chrome and noble alloy options are available. Submit your scan files for case evaluation.
