Effect of Adding Silicon Dioxide (SiO₂) Nanoparticles to a Printable Acrylic Resin Denture Base
Sponsor: Mansoura University
Summary
This clinical study evaluated whether adding a small amount (0.5 wt%) of silicon dioxide (SiO₂) nanoparticles to a 3D-printable acrylic denture material could improve the clinical performance of implant-retained mandibular overdentures. the results showed that the SiO₂-modified denture bases had smoother surfaces and were associated with better peri-implant soft tissue measurements than the conventional 3D-printed denture bases. The modified denture bases also showed lower bacterial counts and reduced Candida albicans levels during follow-up. No implant failures were reported during the study period.

Interventions
Standard 3D-printed acrylic resin denture base
Fabrication of mandibular overdentures using standard 3D-printable acrylic resin without any nanoparticle modification. The dentures are retained by two bilateral mandibular implants with ball attachments.
SIO2 nanoparticle-modified 3D-printed acrylic resin denture base
Fabrication of mandibular overdentures using 3D-printable acrylic resin incorporated with $0.5 wt% silanized SIO2 nanoparticles (homogenized using a high-speed homogenizer). The dentures are retained by two bilateral mandibular implants with ball attachments.
