Kulzer iCEM Universal Plus Review

Kulzer iCEM Universal Plus is a dual-cure resin cement that runs in two modes from one syringe. The FDA cleared it on December 19, 2025, and Kulzer presented it to US dentists at the Chicago Midwinter Meeting in February 2026. This review covers indications, protocols, independent evidence, and where the primer changes the outcome.

TL;DR

• Kulzer iCEM Universal Plus seats crowns, bridges, inlays, onlays, and veneers on natural teeth or implant abutments in self-adhesive or adhesive mode.

• The optional primer carries an acidic silane, so lithium disilicate and other glass ceramics need no separate silane bottle.

• Self-adhesive mode suits retentive zirconia and metal crowns, while onlays and veneers need the primer plus selective enamel etching.

• Independent long-term data on this specific cement are not published yet, so start with the trial kit on routine posterior crowns.

What Is Kulzer iCEM Universal Plus

Kulzer describes iCEM Universal Plus as a resin-based adhesive luting material for indirect restorations, prosthetic devices, and dental cores. It ships as an automix cement with a separate primer bottle, and the primer is what turns a quick self-adhesive protocol into a full adhesive one.

The product sits in a crowded category. Most US practices already stock at least one universal cement, so the useful question is where this system fits in the drawer and which cases it should take over.

Regulatory Status And Launch

The regulatory record is short and clean. The FDA cleared the cement under 510(k) K254063 on December 19, 2025, two days after Kulzer, LLC of South Bend, Indiana filed it.

It is a Class II dental cement under 21 CFR 872.3275, product code EMA. The FDA indications for use cover bonding of composite, all-ceramic, and metal restorations. Bonding of crowns, inlays, onlays, bridges, and veneers to cavities, abutment teeth, or implant abutments; and dental core bonding. The NIH device database holds separate records for each shade and for the primer, all published in January 2026. US dealer listings give Japan as the country of origin.

What Comes In The System

Everything is sold as separate refills, plus a trial kit that bundles cement, primer, and tips. The table below lists the US catalog numbers.

How The Chemistry Works

A handful of design choices explain how one cement covers so many substrates. The descriptions below come from Kulzer's product literature as published through its US dealers, and none of them has been tested independently yet.

The cement uses a double initiator system with hydrophobic and hydrophilic components. The hydrophilic side reacts with the moisture layer on dentin, so adhesion to the tooth begins before the curing light comes near it. That matters on a molar where the light guide cannot reach the distal margin at a useful angle.

The primer carries an acidic functional monomer that Kulzer calls high-PA technology, designed to penetrate enamel and dentin quickly. It also carries an acidic silane coupling agent. Kulzer claims this silane resists bond degradation better than systems built on more alkaline silanes, which is the reason no separate silane step appears in the protocol for glass ceramics.

Henry Schein's catalog copy adds a touch-cure effect, meaning the primer speeds polymerization of the cement where the two meet, even in deep areas the light misses. GC uses a similar idea in its G-CEM ONE Adhesive Enhancing Primer. For a clinician, the practical effect is a faster, more complete set at the bottom of a post space or under a 2 mm zirconia crown.

Indications And Compatible Restorative Materials

Kulzer lists zirconia, lithium disilicate, glass and hybrid ceramics, alumina, and resin-based materials as compatible, and US catalogs add metals. The table pairs each material with the mode most clinicians would choose. It reflects general adhesive principles rather than a Kulzer chart, so the IFU in the box has the final word on each pretreatment.

Material choice still drives most of the outcome. Our comparison of zirconia vs lithium disilicate walks through when each ceramic makes sense, and that decision should come before the cement decision.

Partial-coverage restorations deserve a specific warning. In a randomized split-mouth trial at the University of Regensburg, CAD/CAM partial ceramic crowns luted with a self-adhesive cement had significantly lower survival at 39 months than those placed with a universal adhesive and a conventional resin cement. The cement in that trial was RelyX Unicem 2, not iCEM, but the mechanism applies to self-adhesive chemistry in general. Onlays and overlays belong in adhesive mode.

Self-Adhesive Mode Vs Adhesive Mode

The same syringe works in both modes, and the clinician decides at the chair. Kulzer recommends self-adhesive mode for retentive preparations with lower adhesive demands and adhesive mode with the primer for less retentive cases that need maximum bond strength.

That flexibility is the reason to buy the system. It also creates a quiet risk, since a cement that works without primer tempts a busy team to skip the primer on the short molar prep where it matters most.

When Self-Adhesive Mode Is Enough

Self-adhesive mode fits full-coverage crowns that hold themselves on. Picture a zirconia first molar crown with 4 mm or more of axial wall height and a total taper close to the textbook 10 to 20 degrees. Mechanical retention does most of the work there, and the cement's job is to seal the margin and stay put.

The predecessor product gives some useful context. In a 2013 randomized trial at the University of Pennsylvania, 88 crowns on vital teeth were cemented with either the original Kulzer iCem self-adhesive cement or a resin-modified glass ionomer. The self-adhesive group reported significantly less sensitivity at day 1, and ice-spray scores stayed lower at every recall through 3 weeks. iCEM Universal Plus is a newer formulation, so those numbers cannot transfer directly. They do suggest the family's self-adhesive chemistry is gentle on vital dentin.

Uncut enamel is the weak point. Self-adhesive cements etch enamel poorly, and an Operative Dentistry study found that a 10-second phosphoric acid etch of enamel raised self-adhesive cement bond strength more than shorter or longer etch times. Keep the acid off dentin when using self-adhesive mode, because etched dentin removes the buffering that keeps these cements kind to the pulp.

When The Primer Earns Its Place

Adhesive mode is the right call whenever retention comes from the bond rather than the prep. That includes short clinical crowns on worn molars, over-tapered preps, lithium disilicate and feldspathic restorations, onlays, and veneers with enamel margins.

In adhesive mode, the primer goes on the tooth and, depending on the IFU, on the intaglio surface. Its acidic monomer conditions enamel and dentin, its acidic silane conditions glass ceramics and composite, and its touch-cure effect firms up the cement at the interface. Practices that already rely on a separate universal bond, such as the ones covered in our All-Bond Universal review, will notice one less bottle on the tray.

A simple rule keeps the team consistent. If the prep is not clearly retentive, or the restoration is a glass ceramic, the primer goes on.

Step-By-Step Clinical Workflow for iCEM Universal Plus

A predictable cementation with iCEM Universal Plus follows the same backbone as any resin cement. The protocol below reflects general adhesive practice and the published evidence, and the exact primer, tack-cure, and final-cure times must come from the IFU in the box.

Before Cementation Day

Good cementation starts at the provisional visit. Eugenol in temporary cement can leave residue in dentin and weaken resin bonds, and a meta-analysis of micro-bond studies found a measurable drop in bond strength after eugenol contact. A eugenol-free temporary cement, or a provisional such as the one in our J-Temp temporary resin review, avoids that problem.

A second systematic review found that temporary cementation lowered bond strength when dentin was sealed late, and that the removal method mattered. Gentle provisional removal helps, and a tool like the one in our TempOff review reduces the urge to lever on fragile margins.

Note the planned cementation mode in the patient's dental treatment plan. When the assistant sees "adhesive mode, primer, selective enamel etch" in the plan, the tray arrives set up correctly, and nobody has to stop mid-appointment.

Restoration Pretreatment

The intaglio surface decides as much of the bond as the tooth does. Each material gets its own preparation before the primer.

Zirconia needs air abrasion with 30 to 50 micron alumina at about 1 to 2 bar if the lab has not done it. Our guide on how to bond zirconia crowns explains why hydrofluoric acid does nothing useful on zirconia, and our explainer on air abrasion in dentistry covers the equipment side.

Try-in contaminates zirconia with saliva, and saliva phosphates bind tightly to the surface. A 2022 systematic review and meta-analysis in the Journal of Adhesive Dentistry found alumina air abrasion to be the most effective cleaning method, with a cleaning paste as a reasonable second choice. Alcohol and phosphoric acid performed no better than water. Many clinicians still wipe zirconia with alcohol after try-in, and the data say that habit does not restore the bond.

Lithium disilicate gets a 20-second etch with 4.5 to 5 percent hydrofluoric acid, a thorough rinse, and a dry surface before primer. Feldspathic porcelain needs a longer etch, usually 60 to 90 seconds.

Tooth Preparation And Isolation

Isolation decides whether the cement ever reaches its potential. A rubber dam is the gold standard, and our Nic Tone rubber dam review covers a practical option. Where a dam is not realistic, the system in our DryShield isolation review, combined with cord or a paste such as the one in our 3M Astringent Retraction Paste review, keeps crevicular fluid off the margins.

Clean the prep with pumice and rinse. In self-adhesive mode, dry gently and leave dentin slightly moist, since the hydrophilic initiator needs that moisture. In adhesive mode, apply the primer to enamel and dentin, agitate, and air-thin as the IFU directs. Selective enamel etching before the primer strengthens enamel margins on veneers and onlays.

Seating, Tack Cure And Cleanup

Gel-phase cleanup is the skill that separates a clean margin from a radiographic surprise. The steps below take about two minutes on a single unit.

1. Bleed the automix syringe once before attaching a new mixing tip, so both pastes flow evenly.

2. Load a thin, even layer into the restoration, or inject into a post space with an endo tip from the canal floor upward.

3. Seat with firm, steady pressure and hold the restoration in place.

4. Tack cure each surface for a few seconds, until the excess turns to a rubbery gel.

5. Remove the gel with a scaler or explorer and floss interproximally before the cement hardens fully.

6. Apply glycerin gel over the margins to block the oxygen-inhibited layer.

7. Light-cure every surface for the full time in the IFU.

8. Check occlusion and take a bitewing to confirm no radiopaque cement remains below the margin.

Curing light output matters more here than most teams assume. A light like the one in our VALO Grand curing light review delivers consistent irradiance, and our guide on when to upgrade dental LED curing lights explains how to test an older unit with a radiometer.

Curing Under Opaque Restorations

Light reaching the cement drops fast under thick or opaque ceramics, and dual-cure chemistry exists to cover that shortfall. The evidence shows how much the shortfall can be.

A 2023 laboratory study found that zirconia thicker than 1.5 mm inhibited polymerization of a dual-cured resin cement through light attenuation, leaving more residual monomer and triggering inflammatory responses in cell culture. An earlier study from KU Leuven found that standard yttria-stabilized zirconia still let enough light through to cure the tested cements, while a ceria-based zirconia was too opaque and required self-curing chemistry.

Two practical lessons follow. Cure each surface longer than feels necessary under full-contour zirconia molars, and treat the chemical cure as insurance rather than the plan. The primer's touch-cure effect gives iCEM Universal Plus an edge in adhesive mode here, though no independent degree-of-conversion data on this cement were available at the time of writing.

Shades, Handling And Esthetics

iCEM Universal Plus is built for low technique sensitivity, and the handling reflects that. The automix syringe removes hand-mixing errors and keeps the base-to-catalyst ratio constant.

Each automix tip wastes some material. On single units, that waste adds up, so the real cost per restoration depends on how carefully the team dispenses.

Shade Selection

Four shades cover most clinical needs. The guidance below is general, so a quick check against the actual restoration is worth the time on anterior teeth.

• Translucent suits most crowns and lets the restoration's own shade show through.

• White brightens high-value anterior restorations and bleached dentitions.

• Yellow warms a restoration that reads slightly gray or cool.

• Opaque masks discolored abutments, metal posts and cores, or titanium abutments under thin ceramic.

No matching try-in pastes appeared in the US catalogs reviewed for this article. For high-esthetic anterior work, ask a Kulzer representative or use a water-soluble try-in gel from existing stock.

Color Stability On Thin Restorations

Color stability is an open question for veneers. An in vitro study comparing amine-free light-cure and dual-cure resin cements found that light-cure versions held their color best after long-term aging.

Kulzer has not published the initiator details or color data for iCEM Universal Plus. Until it does, a light-cure veneer cement remains the safer pick for thin, highly translucent veneers, and iCEM Universal Plus fits best under restorations thicker than about 1 mm.

Implant Abutments And The Excess Cement Problem

iCEM Universal Plus is cleared for bonding restorations to implant abutments, which makes it a candidate for cement-retained implant crowns. That indication comes with a responsibility, because residual cement around implants is a recognized cause of peri-implant disease.

In a prospective endoscopic study, excess cement was found in 34 of 42 implants showing signs of peri-implant disease, and signs of disease cleared in 74 percent of test implants after the cement was removed. The study tested no iCEM product, but it applies to any cement placed around an implant.

Custom abutments with margins no more than 1 mm below the tissue make cleanup far easier. A minimal amount of cement, ideally loaded with an extraoral copy-abutment technique that squeezes out the excess before seating, keeps most of it out of the sulcus to begin with, and a radiograph after seating catches what the explorer missed, since the radiopaque cement shows clearly on film.

How iCEM Universal Plus Compares With Other Universal Resin Cements

Every major manufacturer now sells a self-adhesive cement with an optional booster. The table compares system concepts rather than lab numbers, since no independent head-to-head data on iCEM Universal Plus exist yet.

RelyX is the cement most US practices will compare against. Our review of RelyX resin cement covers its handling, and our Scotchbond Universal Plus review explains the adhesive it pairs with. For compromised preps that need the strongest adhesive protocol available, our Panavia V5 review describes a dedicated adhesive cement that still outranks most universal systems on evidence.

iCEM Universal Plus stands out for its single primer covering tooth and restoration, along with touch-cure behavior that helps under opaque crowns. The established brands lead on independent bond-strength data and published clinical survival, and some offer matched try-in pastes. Kulzer's own earlier iCEM Self Adhesive was a self-adhesive cement only, so the Plus version adds an adhesive upgrade path that the original never had.

Price And Value

US list prices in October 2026 put a 9 g syringe refill at about $174, a two-syringe value pack at about $318, and the trial kit at about $292. Dealer promotions regularly take 20 percent off those figures, and Kulzer's second-quarter 2026 offer gave a free refill with two trial kits.

Cement is a small line item on a crown that costs patients $900 to $2,500 in the US, according to our breakdown of dental crown cost. A remake caused by debonding or residual cement costs far more than any price difference between cements, so reliability should outweigh a few dollars per syringe. The full range of cements and bonds we have covered sits in our restorative materials reviews.

Bottom Line

Kulzer iCEM Universal Plus suits practices that want one resin cement and one primer to cover most indirect work, from zirconia crowns to lithium disilicate onlays and implant abutments. Its main value is consolidation. A drawer that once held a self-adhesive cement, an adhesive cement, a silane bottle, and a zirconia primer can shrink to a syringe and a 5 ml bottle, and assistants only need to learn one material's handling.

The two modes need a firm rule behind them. Self-adhesive mode works well on retentive full-coverage crowns, especially zirconia and metal, where the prep does most of the holding. Glass ceramics, onlays, veneers, and short or over-tapered preps belong in adhesive mode with the primer, and the Regensburg data on partial ceramic crowns show what happens when that line is ignored.

Evidence is the honest limit. The FDA cleared the cement in December 2025, and the earlier iCem formulation performed well on postoperative sensitivity in a 2013 randomized trial, but no independent clinical study of iCEM Universal Plus itself has been published. Color stability under thin veneers and long-term bond durability on lithium disilicate are the two questions worth watching as data appear.

A sensible rollout starts with the trial kit on a run of retentive posterior crowns in self-adhesive mode. Once the team has the gel-phase timing down, the next step is adhesive mode on lithium disilicate crowns and short preps, while a light-cure cement stays on hand for thin anterior veneers.
