3-D printed versus conventional overdentures for people with ectodermal dysplasia

Adaptation and Patient Satisfaction of 3-D Printed Versus Conventional Acrylic Overdentures in Patients With Ectodermal Dysplasia: A Crossover Prospective Clinical Trial

NA · Cairo University · NCT07468019

This project will test whether 3-D printed overdentures provide better fit, comfort, and satisfaction than conventional acrylic overdentures for people aged 10–35 with ectodermal dysplasia who have some remaining upper teeth.

What this trial studies

Participants aged 10–35 with ectodermal dysplasia and a few remaining maxillary teeth will receive either a 3-D printed overdenture or a conventionally processed acrylic overdenture and will be followed over time for denture adaptation and patient-reported outcomes. Clinical measures of fit and retention and standardized questionnaires of satisfaction will be collected at scheduled follow-up visits. The comparison focuses on whether digital 3-D printing reduces polymerization shrinkage and improves adaptation versus conventional processing. Oral health and any complications will be monitored throughout the follow-up period.

Who should consider this trial

Good fit: Ideal candidates are people aged 10–35 with ectodermal dysplasia who have a few remaining teeth in the upper jaw and can attend all follow-up visits.

Not a fit: Patients with large anatomical limitations requiring surgery, allergy to denture resins, active pathological changes of the residual ridges, or inability to cooperate with follow-up visits are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, 3-D printed overdentures could produce better-fitting, more comfortable dentures with higher patient satisfaction and fewer adjustment visits.

How similar studies have performed: Clinical evidence specifically in ectodermal dysplasia is scarce, but early reports of digitally manufactured and 3-D printed dentures in other populations have shown promising improvements in adaptation and workflow.
