Direct Laser Interference Patterning (DLIP) on PEEK Coating for Biomedical and Dental Applications.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Polyether ether ketone (PEEK) is widely recognized for its biocompatibility and mechanical stability, making it a promising coating material for dental implants. However, unmodified surfaces may lack optimal properties for osseointegration and antibacterial resistance. Direct laser interference patterning (DLIP) is an advanced technique for introducing controlled micro- and nanoscale surface features to enhance implant performance. This study aims to investigate the surface characteristics, antibacterial effect, and biocompatibility of DLIP-functionalized PEEK coatings electrophoretically deposited on 316L stainless steel (SS). Materials and Methods: PEEK was deposited onto 316L SS substrates via electrophoretic deposition and subsequently functionalized using DLIP to create periodic surface patterns with spatial periods of 1, 1.5, and 2 µm. The modified surfaces were characterized using scanning electron microscopy, contact angle (wettability), and surface roughness measurements. Antibacterial activity was assessed using the turbidity method against Results: The DLIP-functionalized PEEK surface with a 1.5-µm spatial period exhibited the most favorable surface features, with a contact angle of 92 ± 1° and surface roughness of 2.04 ± 0.03 µm. This configuration significantly inhibited Conclusion: DLIP is an effective technique for functionalizing PEEK coatings, improving key surface characteristics that support antibacterial activity and osteoblast cell compatibility. Among the tested configurations, a 1.5-µm spatial period yielded the most promising results. Clinical Relevance: This study supports the application of DLIP-functionalized PEEK coatings for dental implants, offering a novel and translatable surface.
