PDL ® Laser Treatment

1. WHAT IS PDL® LASER SURFACE TREATMENT


PDL® Laser Surface Treatment

Biomate laser surface treatment is a thermal processing technique, which applies high energy density laser (up to 1700 C), focusing on the metal surface to fuse and evaporate the surface with heat. This technique can form unique 3D pores with micro-nano & microchannel texture on the implant surface, suitable for the adhesion and growth of osteocytes that help increase the contact surface area of the bone and fixture, optimizing the effect of cell proliferation and osseointegration.

2. PDL® LASER CREATES SPECIAL FEATURES.

A. Laser creates a thicker oxide layer

Demonstrated by Research from National Chung Hsing University, Taiwan
Laser treatment produces an oxide layer called TiO2. The TiO2 layer with anatase texture can effectively increase the adsorption of protein and enhance the osteoblast adhesion and proliferation, promoting calcification during the bone healing process.

Compared to the 5.5-9.3nm oxide layer of Straumann implants, the oxide layer of BiomateSWISS implants is significantly thicker (110 nm), resulting in superior healing capability.

B. Laser treatment creates a harder surface than SLA-treated one

Demonstrated by Research from National Chung Hsing University, Taiwan
Mahidol University's SEM studies found that Biomate Plus implants exhibit less damage (peeling, pits, deformations) compared to SLA-treated surfaces. The absence of sharp micro-irregularities makes Biomate surfaces more resistant to high torque stress during insertion and retrieval.

C. Laser creates an ultra-clean surface, with no harmful residues

Demonstrated by Research from National Chung Hsing University
Unlike SLA-treated implants that may leave chemical residues, XPS analysis confirms that PDL® laser-treated surfaces contain only Ti, N, O, and C — all naturally occurring elements. Other brands (e.g., Nobel Biocare, Straumann) show additional contaminants like Si, P, S, and Zr.

3. ABOUT TORQUE & STABILITY CREATING BONE FASTER HEALING


PDL® Laser treatment performs the faster bone formation effect

Demonstrated by Research from Cairo University
No need to pursue high torque above 50Ncm anymore, you can do immediate placement and loading! Laser-treated implants can shorten and reduce the initial ISQ drop time and decrease the chance of early failure.

The structure of PDL® Laser treated surface is enhancing Osseointegration

Demonstrate by research from Taiwan University, Taiwan 
The laser-treated surface significantly enhances pre-osteoblast proliferation, promotes mRNA and protein expression/secretion of COL1, SPP1, DCN, and TNFRSF11B, and facilitates extracellular mineralization. These findings strongly indicate that laser-treated titanium surfaces have profound beneficial effects on pre-osteoblast maturation and bone integration, highlighting substantial clinical application potential.

Demonstrate by research from Mahidol University, Thailand
The lack of cell maturity and cell adhesion in Biohorizons samples is still unknown. The presence of organic particles on the BIOMATE implants did not deter cell maturation in this invitro experiment. The advantages of laser surface treatments are numerous, but different structures also yield different cell

7. ABOUT BACTERIAL THERAPY & BIOFILM REDUCTION


PDL ®Laser-treated surfaces showed the lowest biofilm formation

Demonstrated by research from Milan University, ItalyBased on the research on bacterial membranes at the University of Milan, the PDL® laser-treated surface was compared with another Geass laser surface and a machined surface, a polished surface, and a sandblasted surface, a total of five surfaces to compare the formation and amount of biofilm. This study demonstrates that “Laser micro-texturing of titanium surfaces created surface microtopographies and influenced surface chemical composition. Both microtextures were equally effective in reducing biofilm formation and should be further investigated for their capacity of preventing peri-implantitis in vivo.”
