Augmented Reality for Tooth Selection Augmented Reality for Tooth Selection

Completed

• Conditions: Mouth, Edentulous

• Registration Number: NCT03738189
• Lead Sponsor: University of Leeds

Brief Summary

A questionnaire based study to investigate the effectiveness of an Augmented Reality App in the selection of teeth for dentures. Patients dentists and dental technicians are asked to assess the effectiveness of the App in structured questionnaires.

Detailed Description

Background The selection of teeth for dentures has difficulties. The main problem is that patients find it hard to envisage how a particular shape or 'mold' of tooth will look in their mouth. They are currently shown a number of different shaped teeth asked to express their preference.

This research team has developed computer software which now offers an alternative way to assist patients in the selection of the different shaped teeth. The new method uses 'Augmented Reality' (AR) to show the patient a live image of themselves with a selection of teeth in position in the picture. Effectively the patient takes a live video 'selfie' and the image on the screen shows the chosen teeth in their smile. The investigators want to know if this new method of selection improves the process of tooth selection.

Investigation Design This is a prospective observational cohort study which follows selected patients over 2 clinical visits carrying out a questionnaire based investigation of the new Augmented Reality (AR) method to select teeth for dentures.

Objectives This aim of this research is to investigate the effectiveness of the technology. This will be undertaken using 5 questionnaire based outcome measures to be completed by patients, dentists and dental technicians.

Primary Objective The primary objective is to assess the use of Augmented Reality (AR) for tooth selection.

Secondary Objectives

The secondary objectives use structured questionnaires to determine:

1. the patients' assessment of using the Augmented Reality (AR) for tooth selection.

2. the clinicians' assessment of using the Augmented Reality (AR) for tooth selection

3. the dental technicians assessment of using Augmented Reality (AR) for tooth selection

4. the clinicians' assessment of the quality and reality of the images produced by the Augmented Reality (AR) for tooth selection

5. the dentists' assessment of the quality and reality of the images produced by Augmented Reality (AR) for tooth selection

Number of Patients 30 patients will be recruited

Informed Consent Witten Informed consent will be obtained from each participant.
