PDL® Laser Surface Treatment · Clinical Journals

Clinical Evidence & Scientific Validation

A guided overview of peer-reviewed studies supporting PDL® laser-treated implant surfaces.

AI Summary – What you can take away in 1 minute • PDL® laser treatment creates a unique micro-nano 3D surface that increases functional bone contact area and accelerates osseointegration.
• Independent universities in Taiwan, Thailand, Egypt, and Italy report thicker TiO₂ layers, harder surfaces, and reduced biofilm formation.

Quick Guide

Q. What is PDL® Laser Treatment?

Thinking of high-tech lasers sculpting a perfect "micro-nano" 3D home for your bone cells.

Q. Difference from SLA?

It is cleaner and stronger. Physical process with zero residue.

Q. Does this help my healing?

Yes. The unique structure acts like a magnet for cells, accelerating osseointegration.

Q. Is it durable for long-term?

Absolutely. Studies show bone levels remain very stable over time.

INSIGHT

Need high torque (>50 Ncm)?

No. High stability is achieved without excessive bone stress.

INSIGHT

Does it help prevent Biofilm?

Yes. Confirmed effectively reduces biofilm formation.

1. WHAT IS PDL® LASER SURFACE TREATMENT

PDL® Laser Surface Treatment

AI Key Point · Surface concept High-energy laser reshapes titanium into a controlled micro-nano 3D texture and microchannels, increasing contact area and guiding osteocyte growth.

Biomate laser surface treatment is a thermal processing technique applying high energy density laser (up to 1700°C) to fuse and evaporate the surface. This forms unique 3D pores suitable for osteocytes growth, optimizing osseointegration.

2. PDL® LASER CREATES SPECIAL FEATURES.

AI Key Point · Oxide layer, hardness & cleanliness Compared with SLA, PDL® creates a thicker TiO₂ layer (110nm), harder surface, and ultra-clean chemistry.

Demonstrated by Research from National Chung Hsing University, Taiwan

Laser treatment produces an oxide layer called TiO2. Compared to the 5.5-9.3nm layer of Straumann implants, Biomate is significantly thicker (110 nm), resulting in superior healing.

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

3. ABOUT TORQUE & STABILITY

AI Key Point · Torque & ISQ Evidence shows clinicians do not need torque above 50 Ncm. ISQ values show shorter early drop, supporting immediate placement.

4. ABOUT CELL & BIOCOMPATIBILITY

AI Key Point · Cells & hydrophilicity In-vitro studies report enhanced adhesion, proliferation and differentiation on PDL® laser surfaces.

Demonstrated by research from Taipei Medical University, Taiwan

5. ABOUT ANGIOGENESIS

AI Key Point · Angiogenesis SEM findings indicate richer peri-implant angiogenesis around PDL® laser surfaces supporting stable bone remodeling.

Demonstrated by research from National Defense University, Taiwan

6. ABOUT BONE LOSS

AI Key Point · Marginal bone level Split-mouth data show clearly lower marginal bone loss: Laser (0.09) vs SLA (0.58) at 6 months.

Demonstrated by research from Cairo University, Egypt

7. ABOUT BACTERIAL THERAPY & BIOFILM

AI Key Point · Biofilm Milan University confirms PDL® laser surfaces effectively reduce oral biofilm formation, preventing peri-implantitis.

Demonstrated by research from Milan University, Italy

8. ABOUT BONE TO IMPLANT CONTACT (BIC)

AI Key Point · BIC & functional bone area Internal R&D data show higher BIC rate and larger functional bone contact area supporting mechanical anchorage.
