Brief Summary

Study type: cross over within subject clinical trial Primary aim: To compare patient satisfaction among three different RPDs: conventional cast Co-Cr, 3D-printed Co-Cr, and PEEK RPDs. Secondary aim: To evaluate the impact of these RPDs on oral health-related quality of life and patient preference among these RPDs

Conditions

Partially Edentulous Patients

Keywords

Removable partial denture; Patient satisfaction; Digital partial denture; PEEK; 3D printed printed denture; Oral health quality of life

Outcome Measures

Primary Outcomes (1)

• Patient satisfaction using VAG

  Visual Analogue Grade 100 mm scale is used to measure patient satisfaction and comfort as zero indicates the worst and 100 indicates the best response

  Delivery of the first denture type 1st questionnaire 30 days after receiving the first denture 7 days wash out Delivery of the second denture type 2nd questionnaire 30 days after using the denture 7 days wash out Final questionnaire after 30 days

Secondary Outcomes (2)

• Oral Health related Quality of Life OHRQoL

  Delivery of the first denture type 1st questionnaire 30 days after receiving the first denture 7 days wash out Delivery of the second denture type 2nd questionnaire 30 days after using the denture 7 days wash out Final questionnaire after 30 days

• Patient preference

  After all the three dentures treatment phase 30 days after the delivery of the last denture according to sequence randomisation Study time line was 6 months from recruitment to final questionnaire

Study Arms (3)

Conventional cast Co-Cr removable partial denture

ACTIVE COMPARATOR

This type of RPD is constructed from Cobalt Chromium metal framework using the lost wax technique conventional casting of a wax pattern made on an investment cast.. Each participant used the conventional denture for 30 days then they received the VAS and OHIP-14 questionnaire about their denture experience..Then wait one week without any dentures until they received the second denture type

Device: Conventional cast Cr-Co RPDs

3D Printed Cr-Co removable partial denture

EXPERIMENTAL

This is a digital RPD made from Cobalt Chromium metal which is printed by a 3D printer using selective laser melting technique..Each participant used the 3D printed denture for 30 days then they received the VAS and OHIP-14 questionnaire about their denture experience..Then wait one week without any dentures until they received the next denture type

Device: 3D Printed Cr-Co RPDS

Milled PEEK removable partial dentures

EXPERIMENTAL

This is a digital type of RPD made by milling polyetheretherktone discs using a milling machine..Each participant used the PEEK denture for 30 days then they received the VAS and OHIP-14 questionnaire about their denture experience..Then wait one week without any dentures until they received the other denture type

Device: Milled PEEK RPDs

Interventions

Conventional cast Cr-Co RPDs DEVICE

Conventional Cr-Co RPD is constructed by the standard lost wax technique to act as active comparator being the traditional way of RPD construction

Conventional cast Co-Cr removable partial denture

3D Printed Cr-Co RPDS DEVICE

3D Printed Cr-Co was constructed digitally using Laser Melting technology to 3D print the Cr-Co RPD to the same design used with the conventional and the patient used every denture for 30 days with one week wash out

3D Printed Cr-Co removable partial denture

Milled PEEK RPDs DEVICE

PEEK disc was milled using milling machine to construct RPD framework to the same design as other 2 groups, each patient will use all the 3 dentures for one month but with different sequences, after each type one week washout separated between the groups

Milled PEEK removable partial dentures

Model Details: 3 intervention arms will be used as participants are randomly assigned to one of the 3 dentures Conventional, 3D printed, or PEEK for one month then after one week washout every patient will switch to another type of dentures for another one month, the final phase after a week of rest each patient will try the third type
