About this study
Official title: Comparison of Patient Satisfaction and Chewing Efficiency Between Conventional and 3D Printed Complete Dentures. A Randomized Crossover Clinical Trial
Twenty completely edentulous patients were enrolled in this study. Each patient received two types of prostheses. 1) Conventional complete dentures. 2) 3D printed dimethacrylate-based resin complete dentures. Patient satisfaction was assessed using the oral health impact profile (OHIP-EDENT-N) survey questionnaire, and masticatory performance was evaluated with the two-colored chewing gum mixing ability by evaluation of the standard deviation of hue at (T0) at the time of complete denture insertion, (T3) after 3 months of denture use and (T6) after 6 months of denture use.
Read the detailed description
For each patient, conventional maxillary and mandibular complete dentures were constructed, followed by 3D printed complete dentures construction as follows: Scanning of maxillary and mandibular complete dentures and scanning of master casts were done using 3D scanner (VDSL Home Gateway model EchoLife DG8045 China) after lightly coated with anti-glare spray (Siladent Marmoscan spray basic Ref. 250022). The resultant data in STL format were transmitted to the CAD-CAM complete denture provider using a purpose-built software program (Exocad DentalIDB 2.4 plovdiv7290[version 2.4 Enginebuld 7290]). The anatomic landmarks were identified, and the peripheral limits were marked on a virtual model in the design software, which then were served to design the definitive complete denture.
The scanned STL image of the conventional complete denture which have been previously constructed was superimposed on the newly designed denture for comparison of polished surface, teeth alignment, size, and form of teeth. A digital preview was generated and sent for approval before fabrication.
Printing Preparation: The denture base shade was selected, and then the cassette of the 3D printer (RASDENT 3D printer) was filled with fresh DENTCA Denture Base II dimethacrylate-based resins with photo-initiator). Then the printer door closed. Printing procedures: The denture base model STL file was uploaded into the software. The denture base was oriented vertically on the build platform. Supports were generated around the perimeter of the denture base. The desired slice thickness was selected and then the printing was started. Cleaning, Bonding teeth to the denture base, Post-curing procedures, Finishing Evaluation of patient satisfaction: The OHRQoL of the patient was assessed using an instrument called OHIP-EDENT-N10.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
conventional complete dentureOther
conventional complete denture. The succession of complete denture insertion was randomized to reduce the impact of the order of the complete denture on patient satisfaction outcomes. Each denture was used for 3 months followed by 2 weeks rest period without wearing the denture then the other type of denture was delivered and used for another 3 months and vice versa.
3D complete dentureOther
3D complete denture. The succession of complete denture insertion was randomized to reduce the impact of the order of the complete denture on patient satisfaction outcomes. Each denture was used for 3 months followed by 2 weeks rest period without wearing the denture then the other type of denture was delivered and used for another 3 months and vice versa.

What is being measured
The primary outcome is the main question the study is designed to answer.
Patient satisfaction
The Oral health-related quality of life (OHRQoL) of the patient was assessed using an instrument called OHIP-EDENT-N A simple score was calculated by adding the responses to all the questions (0 = never; 1= seldom; 2 = fairly often; 3 = often; 4 = very often)
Measured: 6 months
Secondary outcomes (1)
chewing efficiency
two-color mixing ability test (colorimetric method)
Measured: 6 months

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Patient satisfaction (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Dec 2023.
