New 3M Adhesives Build on a History of InnovationNewsIf any single technology has made 3M a household name, it is adhesives. As the world’s

leading adhesives manufacturer, 3M’s understanding of adhesives dates back to 1902 when

the company introduced its � rst product, sandpaper, which consisted of abrasive minerals

and paper held together by an adhesive developed by 3M scientists.

Global ImpactSeemingly mundane in purpose—to join materials—adhesives actually comprise one of

3M’s most sophisticated technology platforms. This platform has generated thousands of

innovative and useful products that span the full spectrum of stickiness with applications in

countless markets. In fact, 3M uses this technology in approximately 40 percent of its products,

from Post-it® Notes to 3M™ ESPE™ Adper™ Scotchbond™ Multi-Purpose Plus Adhesive.

Dental AdhesivesStarting with the introduction of Scotchbond™ Adhesive in 1983, 3M ESPE has served

the dental industry with new adhesive products to the market that deliver high-quality

performance. Scotchbond Adhesive was followed by 3M ESPE’s Light Cure Scotchbond™

Adhesive and then by Scotchbond™ Dual Cure Adhesive, which is cured both chemically and

with light. Then, 3M™ ESPE™ Scotchbond™ 2 Adhesive was introduced, the � rst adhesive to

employ an acidic primer material as the � rst step of the bonding process.

Scotchbond™ Multi-Purpose Plus Adhesive was the next step in adhesive technology, using

a polymer developed for Vitrebond™ Resin Modi� ed Glass Ionmomer (RMGI) Liner/base

to solve the variable dentin bond strengths seen with the Scotchbond 2 adhesive. Scotchbond

multi-purpose plus adhesive established dentin bonding agents as clinically proven materials

in the dental industry. In the years after the introduction of that industry-leading innovation,

3M ESPE continued to bring leading products to market.

Primer and Adhesive in OneIn 1997, 3M™ ESPE™ Adper™ Single Bond Adhesive was introduced. A two-component,

total-etch bonding agent, this generation of products combined primer and adhesive into a

single composition. Then in 1999, the original 3M™ ESPE™ Prompt™ Self-Etch Adhesive was

introduced and was one of the � rst self-etch adhesives on the market. It was the � rst product

available in the convenient, unit-dose, L-Pop™ delivery system, allowing the customer to etch,

prime and bond in a single step.

The Next Step: Nanotechnology3M’s investment in nanotechnology has resulted in major breakthroughs in the dental

restoration � eld. 3M ESPE was the � rst organization to commercialize true nanotechnology

with 3M™ ESPE™ Filtek™ Supreme Plus Universal Restorative. Since its landmark introduction

in 2002, Filtek Supreme Plus universal restorative continues to be a leading restorative

solution in the United States. 2004 saw the introduction of a nano� lled version of single bond

adhesive, Adper™ Single Bond Plus Adhesive.

Improving Self-Etch TechnologyGlobal adhesive trends show that self-etch adhesives are gaining popularity and growing at a

faster rate than total-etch adhesives. More customers today want products that offer reduced

postoperative sensitivity, fewer steps and easier procedures. In response to this, 3M ESPE has

launched two new options in self-etch dental adhesives. Adper™ Easy Bond Self-Etch Adhesive

is a one-bottle, one-coat self-etch adhesive that offers strength, simplicity and convenience.

[� g. 3] Adper™ Scotchbond™ SE Self-Etch Adhesive is a two-bottle, high-performance

self-etch adhesive with a color-change indicator and contains a zirconia nano� ller that gives

improved bond strength and radiopacity. [� g. 4]

A Future Built on Strong BondsThe dental industry is ever-changing, and 3M ESPE is committed to providing its customers

new, relevant products that offer unique advantages to their patients. With its own base of

proprietary technologies and global regulatory expertise —including many in the realm of

adhesives— quality, innovation and relevance are a given at 3M ESPE and will be in the

future as new challenges are met with industry-leading solutions. ■

3M ESPE Expands Implant Offeringswith Aquisition of IMTEC Corp. NewsWith the recent acquisition of IMTEC Corp., 3M ESPE is positioned to offer dental

professionals a new, complete approach to implants that will lead the industry. A manufacturer

of dental implants and Cone Beam Computed Tomography (CBCT) scanning equipment

for dental and medical radiology, gives 3M ESPE access to technology and products that

will signi� cantly enhance its implantology offerings. [� gs. 5 – 7] “Our combined digital

products and expertise will enable a digital ‘total restorative’ approach with more options

than ever, including IMTEC implants, 3M™ ESPE™ Lava™ Crowns, and 3M’s advanced digital

work� ow solutions,” said Jeffrey Lavers, Vice President and General Manager, 3M ESPE.

“Together, we will have an end-to-end implantology solution, making the process easier,

faster and better for dentists everywhere.”

Investing in Implantation Technology and the Future of DentistryDental implants are rapidly emerging as a standard of care for dentistry, and 3M ESPE is

committed to supporting the future of this proven technique. The acquisition of IMTEC will

allow 3M ESPE to not only offer more to dental professionals now, but also to develop cutting-

edge digital technology for the future.

For traditional implants, titanium screws replace the roots of extracted teeth and are

integrated into the bone over the course of a few months to become a highly stable platform

for a crown, bridge, or full-arch denture. IMTEC provides a more immediate solution with its

mini dental implants. These are small-diameter, single-unit dental implants that don’t require

invasive surgery—so bone trauma is minimal and patient discomfort is limited. Mini dental

implants are primarily used for denture � xation and allow for immediate loading. ■

Light Body VPS Impression Material

Imprint™ 3 Light Body VPS Impression Material Shown to Be Effective for Inexperienced UsersClinical StudyA study being conducted at the University of Alabama at Birmingham seeks to evaluate

the effectiveness of two impression materials when used by inexperienced clinicians—in

this case pre-doctoral dental students. It is a randomized clinical trial using a new Vinyl

Polysiloxane (VPS) impression material 3M™ ESPE™ Imprint™ 3 Light Body and Aquasil™

Ultra LV, LD Caulk, another VPS impression material.

To date, 110 patients at the University of Alabama in Birmingham School of Dentistry have

been recruited. The patients were randomly assigned to two groups. The pre-doctoral dental

students used one of the two products to create impressions for indirect � xed full-coverage

restorations. Examiners evaluated the impressions based on the criteria of position of the

tooth, type of preparation, preparation � nish line, and gingival bleeding score.

Researchers reported that “Imprint 3 light body impression material produced clinically

better � rst impressions compared to Aquasil Ultra LV.” The study has yet to be concluded and

further analysis will be completed, but they were able to con� dently report “the Imprint 3

light body impression material produced more clinically acceptable impressions with

inexperienced operators.” ■

Astra Tech Partnership Brings New Technology to Lava™ Milling and Design CustomersNews3M ESPE and Astra Tech AB have created a global partnership. Now, 3M ESPE will offer

Astra Tech’s Atlantis™ patient-speci� c abutments to 3M™ ESPE™ Lava™ Crown and Bridges

customers. The two companies have collaborated to develop an interface which will enable

the 3M™ ESPE™ Lava™ Scan ST Design System to communicate directly with Astra Tech’s

Atlantis technology.

This new development will make it possible for Lava Scan ST users to transfer digital scan

information of the patients’ oral geometry to Astra Tech’s Atlantis design and manufacturing

facilities worldwide. Shipment of physical models will no longer be necessary, lowering the

cost and reducing the overall turnaround time.

“This is an important step in 3M ESPE’s strategy to enable end-to-end digital work� ow

for our customers,” said Wayne Roen, Director of Digital Restorative Dentistry, 3M ESPE.

The companies anticipate a commercial launch in the United States later in 2008 with other

markets to follow.

Working together, 3M ESPE and Astra Tech hope to further enhance the ef� ciency of

dental laboratories with additional digital work � ow, and to continue delivering innovation

to the industry. ■
