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.
No residues of harmful substances on the surface. It is the cleanliest implant surface in the world
Energy focused on one spot. It is rapid, extremely clean, and suitable for the selective modification of surfaces and allows the generation of complex microstructures/ features with high resolution. These advantages make the technique interesting for geometrically complex biomedical implants. The only residues on BiomateSwiss implants are Ti, N, O, C. The implants on the market have residues of various elements. Titanium is an element that has been scientifically proven to be beneficial to osseointegration. The analysis of chemical bond by National Chung Shing University, Taiwan shows :
Laser creates a thicker oxide layer
The laser produces an oxide layer called TiO2, which is formed on the surface of the pure titanium when contacting oxygen. 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.

Laser creates 3D pore and MicroChannel
First, Biomate patented Precision Dimensional Laser (PDL) creates a unique microchannel with a micro-nano complex 3D pore. 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.
Mahidol University conducted a study designed to analyze the surface chemistry and topography of laser-irradiated Titanium implants and evaluate the cell morphology and cell adhesion of Human Fetal Osteoblasts(HFOB) seeded on the implants. HFOB cell adhesion is possible after 48 hours in laser-irradiated titanium.
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.
PDL laser-treated implant reveals more MSCs attachment and more angiogenesis
Assistant Prof. Dr. Yuh of National Defense University presented that PDL laser-treated implants reveal more MSCs attachment and angiogenesis. The precision dimension laser (PDL) treated titanium surface shows a 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 an aging population.
The structure of the surface is substantial
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 enormous 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, it had minimal surface alteration and more durable properties. Thus, the macro-nano roughness is not easy to damage at the high torque force. It demonstrates that the constructure of the surface is very firm.
The best Hemocompatibility
Fixture with Hemocompatible surface improves the adhesion of protein in the blood, increasing the coagulation of blood. 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.
Contact Angle of Blood
Blood testing (Dripping)
Due to the experiment of contact angle of blood,
it shows the contact angle of blood in BiomateSwiss is 0°.

Higher BIC (Bone to Implant Contact) rate
PDL Surface treatment applies precise parametric design. Through high efficacy laser luminous energy to strike qualitative micro-nano, complex 3D texture that helps increase the contact surface area of the bone and fixture optimizes the effect of cell proliferation and osseointegration.
laser-treated surfaces showed the lowest biofilm formation
We worked with Milano University, Italy in 2019. The research title is, "Laser micro texturing of titanium implant surfaces to reduce oral biofilm formation." Because of COVID19, this research has been delayed. On September 16-18, 2021, the researcher Dr. Anderi Ionescu has just been presenting at the hybrid meeting of the Continental European Division of the International Association for Dental Research with most of this data on September 16, 2021. His research demonstrates that “Laser micro texturing of titanium surfaces created surface micro topographies and also influenced surface chemical composition. Both (Geass and Biomate) macrotextures were equally effective in reducing biofilm formation." From 48 hours viable oral microcosm (optical density units) we can see Biomate is much less than Geass because of the different surface structure“ Please refer to his poster,
Biomate implant is very suitable for Immediate replacement & loading
A preliminary study at the master program of oral implantology Cairo University conducted by Refky A, and Elkhadem A and presented on Bangkok International Dental Implant Symposium 2019, “The impact of PDL versus RBM implant surface treatment on implant stability during healing: A preliminary clinical study Aim: Compare changes in ISQ values of PDL versus RBM surfaces during the healing period.” This study finds that: Conventional sandblasted implant surfaces show implant stability dip from week 2-6 while PDL implants show gradual increase instability throughout the healing phase. Please refer to the attached studies.
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.
