PDL | Laser Surface Treatment
Biomate laser surface treatment is a type of thermal processing technique, which applies high energy density laser (up to 1700 ﾟ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.
The TiO2 layer with anatase texture can effectively increase the adhesion of protein. Studies show that the oxide layer on the
titanium surface can optimize the adhesion and regeneration of blood and osteocyte. National Chung Hsing University, Taiwan, conducted this SEM analysis.

The microchannel induced the precursor of osteoblast directional moving onto the implant surface, and the micro-nano
3D pore improved the efficiency of osteoblast adherence, proliferation, differentiation, and finally, bone formation.
This structure increases the contact surface area of the bone and fixture and optimizes the effect of cell proliferation
and osseointegration. Taipei Medical University conducted this study.
However, 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 in-vitro experiment.
The precision dimension laser (PDL) treated titanium surface shows higher affinity for periodontal stromal cells and induces better peri-implant angiogenesis ex vivo. This unique anglophilic surface treatment developed by Biomate may provide better peri-implant treatment outcomes for the aging population.

According to a pilot study conducted by Mahidol University, Biomate plus presented only a few damages over the implant.
The damage could be found as chipping, pit, and flattening. SLA implant presented pit, flattening, and fuse surface in larger
amount compared to Biomate Plus.
The defect could be easily found especially in apical thread corresponding to self-tapping design.
Biomate plus surface did not present the sharp asperities in micro level, therefore this might be the reason why it had minimal
surface alteration and more durable properties. Therefore, the macro-nano roughness is not easy to be damaged at the high
It demonstrates that the constructure of the surface is very firm.

The best Hemocompatibility
PDL Laser-treated implant shows hemocompatible characteristics. Some scholars said that hemocompatible fixture is beneficial
to cell proliferation and differentiation, improving the growth of osteocytes.
Blood testing (Dripping)
Due to the experiment of contact angle of blood,
it shows the contact angle of blood in BiomateSwiss is 0°.

Chung Shan University has conducted research to find that bacterial on the complex structure can be cleaned by the combination therapy
of Er: YAG laser and aPDT system can clean deeply and efficiently into microchannels for both SLA and PDL surface without altering the surface architecture, could be a useful cleaning method for peri-implantitis therapy, especially for a nano microtextured surface.
In addition, this research finds that bacterial, A. actinomycetemcomitans, attached to the deep site of the complex 3D structure is not a big difference between 4 hours an d48 hours.
It also shows that A. sctinomycetemcomitans doesn’t attach to the laser surface as much as on SLA surface. A. actinomycetemcomitans cause
After this preliminary, Prof. Dr. Amr conducted a clinical study and presented the result on June 6, 2021, "Implant Stability Changes for PDL Versus SLA Treated Surfaces in Immediate Extraction Cases: A Randomized Controlled Clinical Trial." This study finds that 1. Laser treatment of the implant surface seems to be a promising approach to promote faster bone healing, 2 PDL implant maintained higher implant stability levels in immediate implants compared to SLA, and 3. PDL implant can be a game-changer in immediate extraction sockets. Please refer to the attached studies.
