Summary

Purpose: To evaluate the effect of adding nano ZrO2 and nano TiO2 nanoparticles on trueness and dimensional deviation of maxillary 3D printed denture base resin on completely edentulous patients.

Materials and Methods: This study was carried out on 24 completely edentulous patients. The patients were divided randomly into three equal groups; Group I: Patients received 3D printed maxillary complete denture without additives, Group II: Patients received 3D printed maxillary complete denture reinforced by Nano ZrO2 (0.4%) by Wt and Group III: Patients received 3D printed maxillary complete denture reinforced by Nano TiO2 (0.4%) by Wt. Trueness was evaluated by scanning the denture using an extraoral scanner after the printing process, before insertion. Dimensional deviation was evaluated by scanning the denture using an extraoral scanner at the time of insertion and after 6 months, 12 months, and 18 months. The trueness and dimensional deviation values were analyzed using repeated measure ANOVA, followed by multiple comparison Turkey test.

Conditions

  • Denture Hyperplasia

Interventions

OTHER

nanoparticles

Nanoparticles improve the dimensional stability of 3D printed denture base resin, so preventing instability of the denture over time
