About this study
Official title: Patient's Expectation and Satisfaction of Implant-supported Prostheses After Excision of Pathological Jaw Lesions: A Prospective Follow-up Study
Objective: The aim of this prospective study was to investigate the patient-reported outcome measures (PROMs) of implant-supported prostheses (ISP) among patients who had excised pathological jaw lesions.
Material and Methods: Patients who met the inclusion/exclusion criteria in a dental teaching hospital were recruited. Data pertaining to sociodemographic factors, conditions requiring surgery, surgical procedures and related complications, and types of ISP were collected. Patients' expectation and satisfaction to the ISP including oral health, self-perceived appearance, speech, chewing ability, oral comfort and ease of cleaning were assessed using the visual analogue scale (VAS, 0-100) and global transitional scale/judgement (Likert scale). Data were analysed using t-test and chi-square tests at the significance level α=0.05.

What is being measured
The primary outcome is the main question the study is designed to answer.
Patient expectation of implant-supported prosthesis
Visual analogue scale 0-100 which 0 is "No expectation" and 100 is "High expectation"
Assess general satisfaction, appearance, speech, chewing hard/soft/fibrous foods, comfort, cleaning, occlusion, stability and in comparison to natural teeth
Measured: Before receive implant-supported prosthesis (baseline)
Patient satisfaction of implant-supported prosthesis in 3-point Likert transition scale
Assess changes in oral condition, appearance, speech, chewing hard/soft/fibrous foods, oral comfort and cleaning following jaw surgery and oral rehabilitation
Global transition judgements: Better, No difference, Worse
Measured: Before (baseline) and 3 months post-insertion of implant-supported prosthesis
Patient satisfaction of implant-supported prosthesis in 0-100 visual analogue scale
Visual analogue scale 0-100 which 0 is totally unsatisfied and 100 is totally satisfied
Assess oral health, appearance, speech, chewing hard/soft/fibrous foods, comfort, cleaning, occlusion, and the ability to chew and bite
Measured: 3 months post-insertion of implant-supported prosthesis
Patient satisfaction of implant-supported prosthesis in 5-point Likert scale
Assess
- Feeling of health of own teeth, lips, jaw and mouth Global transition scales: Very good, Good, Fair, Poor, Very Poor
2: Extent of oral health affecting overall life Global transition scales: Very much, A lot, Some, Very little, Not at all
Measured: 3 months post-insertion of implant-supported prosthesis

Questions about this trial
What is this clinical trial studying?
An observational study of Missing Teeth, run by The University of Hong Kong.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 May 2021. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 expectation of implant-supported prosthesis (time frame: Before receive implant-supported prosthesis (baseline)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04873635, which also lists 31 linked publications.
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 10 May 2021; AzTrials last refreshed its copy on 8 Nov 2026.
