“…The results demonstrated a decrease in Ra after the coating for almost all the groups. This finding was similar to the results of a previous study 35 with a similar experimental protocol in which lower Ra values were achieved as a result of the coating. Interestingly, the coating of specimens finished with 2400 grit initial finish had no effect on the surface roughness.…”

“…However, as the fitting surface cannot be exposed to finishing treatment and constitutes the main area of bacterial accumulation and growth, Parylene coating can still be beneficial by producing smoother surfaces, which may also be more abrasion-resistant. 35 The use of abrasive paper as the finishing medium allowed for standardization as a polishing machine was used to eliminate the potential errors of manual handling. The mean surface roughness (2.69 μm) achieved by the use of 1000 grit abrasive paper (Group A) represented more closely the expected roughness of a fitting surface of a removable dental prosthesis, which can vary between 3.4 and 7.6 μm.…”

“…The mean surface roughness (2.69 μm) achieved by the use of 1000 grit abrasive paper (Group A) represented more closely the expected roughness of a fitting surface of a removable dental prosthesis, which can vary between 3.4 and 7.6 μm. 22,35 A noncontact laser profilometer was used to measure surface roughness, and the Ra, arithmetic average height was calculated. Ra is the most common amplitude parameter used to characterize surface roughness 10,19,35 and was preferred over measuring the Rz (ten point height), which is more sensitive in cases of high peaks and deep valleys or the Rq (root mean square roughness), which is appropriate when a large deviation from the mean line is present.…”

“…Groups A and Ap1 were common to both experiments. The sample size per group (20 specimens) was determined from data from previous publications 34,35 and software (Sample Size Tables for Clinical Studies v1.0; National Cancer Center). All 160 specimens produced were finished with abrasive paper (Waterproof silicon carbide paper;…”

“…34 Parylene-coated PMMA has also demonstrated a significantly higher abrasion resistance to mechanical wear (brushing with toothpaste and pumice) compared wth the uncoated specimens. 35 Therefore, the potential use of Parylene as a coating material for PMMA intraoral prostheses warrants further investigation.…”

Statement of the Problem. The colonization of micro-organisms on acrylic resin dentures may result in denture-induced stomatitis. No efficient coating has yet been proposed to address this issue. Purpose. The purpose of this in vitro study was to assess the effect of various initial surface finishes and different Parylene (P) coating thicknesses on the surface roughness (Ra) and surface free energy (SFE) of Parylene coated polymethyl methacrylate (PMMA). Material and Methods. One hundred and sixty PMMA specimens were produced and divided into 8 groups as follows: Group A: uncoated-1000grit finish; group Ap1: 10 μm P coated -1000grit finish; group B: uncoated -1200grit finish; group Bp: 10 μm P coated -1200grit finish; group C: uncoated2400grit finish; group Cp: 10 μm P coated -2400grit finish; group Ap2: 20 μm P coated -1000grit finish; group Ap3: 30 μm P coated -1000grit finish. The Ra of all specimens was measured with a noncontact profilometer. To calculate the SFE, the Owens-Wendt approach was applied after measuring the contact angles with a goniometer. The topography of the specimens was observed by scanning electron microscope.

Poly(para‐xylylene) (PPX) is a robust and biocompatible coating material that is widely used in various applications, including electronics, aerospace and defense materials, automotive materials, and biomaterials. In this progress report, recent developments in PPX technology ranging from the advancement of physical chemistry properties and structural properties for device integration to the transformation of 3D monolith materials of PPX with controls in outer and inner structures at the micro‐ and nanometer scales are highlighted. Based on emerging chemistry studies on [2.2]paracyclophanes, which are primarily used precursors to synthesize PPX via vapor deposition polymerization, functionalization, and the creation of a wide variety of functional PPX derivatives are demonstrated without resistance. Widely used as an interface coating material, PPX is processed to form integrated structural materials and has already been found to be useful in the market as part of electronic and medical implant products. Using a newly innovated transformation to fabricate PPX through templates (metal‐organic frameworks, liquid crystal, ice crystal), 3D monoliths, nanoscale particles, hierarchical and gradient interior structures, and dynamically transformable shapes at the nanoscale are demonstrated. A vast landscape of novel applications and device products is expected based on the already established R&D and market maturity of PPX.
