2023 ACP ANNUAL SESSION

Purpose: Describe a workflow for the fabrication of an interim complete denture for an ectodermal dysplasia patient.

Introduction:

•A 12-year-old male patient presented to the Advanced Prosthodontic Clinic at the Ohio State University needing a new complete denture.

•The patient was diagnosed with Ectodermal Dysplasia, an inherited disorder impacting the development of ectodermal-derived structure.

•An intraoral evaluation revealed teeth #3, 6, 11, 14, 15, 27, R.

•A complete maxillary and mandibular denture. Made when he was 9-years-old.

•After detailed assessment of patient’s medical history and dental condition, a comprehensive treatment was planned with maxillary and mandibular complete denture.

Methodology:

• A diagnostic maxillary and mandibular intraoral scan was taken for the design of new complete denture.

•Complete maxillary and mandibular denture scan was taken with the intaglio and the occlusal surface of existing patient’s complete denture.

•CAD software was used to align the intraoral scan to the denture intaglio scan using teeth as reference.

•Denture’s intaglio surface was closely aligned to the intraoral scan to create a new denture base was created by keeping the same occlusal surface.

•The denture was then printed with a modified intaglio surface for a new final impression.

•Final impression was taken for both maxillary and mandibular arch using light and heavy PVS material. Bite record was taken keeping the same vertical dimension but with a new centric relation.

•The denture was scanned with the new final impression and the occlusal surface for both maxillary and mandibular with the new bite record.

• The scans were then imported to the CAD software to design a new interim complete denture.

•A new denture was then designed, 3D printed, relined with a soft reline intraorally and delivered.

Result :

•The modified printed denture was used to fabricate a new interim complete denture for the patient is two steps.

Conclusions:

•Predictable results for a growing patient that may need multiple prostheses

•Digital technology like scanning and printing can lead to a much faster and predictable results.

3D printed dentures can be made in two or three clinical visits for the patient
