Control cellular migration - control esthetic outcomes

Only the Laser-Lok surface has been shown using light microscopy, polarized light microscopy and scanning electron microscopy to also be effective for soft tissue attachment. 1,2

better implants, better biology

Laser-Lok has been shown to reduce crestal bone loss to as little as 0.35mm over 3 years.4 Studies comparing traditional and competitor implants to Laser-Lok have shown Laser-Lok to be superior in maintaining crestal bone.5,6
 

"Laser-Lok gives us the opportunity to maintain crestal bone and maintain the interproximal papilla" 3

better biology, better results

The Laser-Lok surface has been shown to reduce probing depths by 1.21mm compared to Nobel Replace Select implants.6 Increased probing depths have been associated with increased risk of peri-implant disease and implant failure.7

What are Laser-Lok microchannels?

Laser-Lok is an organized surface treatment

Laser-Lok is a series of precision-engineered cell-sized channels laser-machined onto the surface of dental implants and abutments.

different than other surface treatments

Dental implants gained notoriety after Prof. Branemark discovered osseointegration in the 1950's using a machined surface.

To improve the osseointgration of dental implants manufacturers began producing randomly roughened surfaces, typically by blasting or acid etching titanium. Random topographies lack connective tissue attachment, causing proliferation and apical migration of epithelial cells.8

Laser-Lok is the only dual affinity dental implant surface, designed to osseointegrate12 and attract a true, physical connective tissue attachment.1

Virtually all dental implant surfaces on the market are grit-blasted and/or acid-etched. These manufacturing methods create random surfaces that vary from point to point on the implant and alter cell reaction depending on where each cell comes in contact with the surface.9 While random surfaces have shown higher osseointegration than machined surfaces,5 only the Laser-Lok surface has been shown using light microscopy, polarized light microscopy and scanning electron microscopy to also be effective for soft tissue attachment.1,2,9,10,11,12,13,14,15

the clinical advantage

The Laser-Lok surface has been shown in several studies to offer a clinical advantage over other implant designs. In a prospective, controlled multi-center study, Laser-Lok implants, when placed alongside implants with a traditional surface, were shown at 37 months post-op to reduce bone loss by 70% (or 1.35mm).5 In a retrospective, private practice study, Laser-Lok implants placed in a variety of site conditions and followed up to 3 years minimized bone loss to 0.46mm16 In a prospective, University-based overdenture study, Laser-Lok implants reduced bone loss by 63% versus Nobel Replace Select®.6

latest discoveries

The establishment of a physical, connective tissue attachment to the Laser-Lok surface has generated an entirely new area of research and development: Laser-Lok applied to abutments. This provides an opportunity to use Laser-Lok abutments to create a biologic seal16, 18 – a solution that offers the best of both worlds. Alternatively, Laser-Lok abutments can support peri-implant health around implants without Laser-Lok.17 Multiple pre-clinical and clinical studies support both of these concepts. Most recently, the combination of Laser-Lok abutments, implants and platform switching was shown to regenerate crestal bone surrounding the implant.2,12,13,14,15
