Clinical Evaluation of 3-D Printed Partial Denture Space Maintainer

Tanta University

Status: Enrolling

Conditions: Gingival Health; Space Maintenance

Identifiers

NCT06825273

# R-PED-1-25-3169

Details and patient eligibility

About

Primary dentition is the most suitable space maintainer for permanent teeth. However, as infants often lose their primary teeth too soon, using a space maintainer is the most efficient, long-lasting, and economical way to prevent malocclusions and function impairment in the future. Regarding personalized appliances, space maintainers in digital pediatric dentistry have made significant progress. Digital technology decreases the manual manufacturing stages that take a long time and increases the reliability and durability of digital fabrication procedures.

40 participants in 2 patient groups

conventional acrylic partial denture space maintainer

Active Comparator group

Description:

an elastomeric impression will be done to produce a plaster cast then a conventional acrylic partial space maintainer will be fabricated and delivered for the child patient.

3-D printed partial denture space maintainer

Experimental group

Description:

A 3-D intraoral scanner will be used to produce digital models. STL file will be used to design a 3-D printed partial denture space maintainer which will be delivered to the child patient.
