Clinical and microbial study of reinforced 3D-printed maxillary denture base resin: a randomized trial.

ABSTRACT:

Statement of problem

The 3D-printed denture base resin needed reinforcement.

Purpose

To evaluate the effects of adding nano ZrO2 and nano TiO2 on microbial colonization and patient satisfaction with 3D-printed maxillary complete dentures.

Materials and methods

Twenty-four patients who needed complete dentures were randomly distributed into three equal groups. Group I: Patients used maxillary complete dentures 3D printed without the addition of any additives. Group II: Patients used maxillary complete dentures 3D after reinforcement by Nano-ZrO₂ (0.4%) by weight. Group III: Patients used maxillary complete dentures 3D printed after reinforcement by Nano-TiO₂ (0.4%) by weight. For microbial evaluation, a cotton swab was taken from the mucosa of the
