The Efficacy of Different Gingival Displacement Methods Before Definitive Digital Impression

Egypt32 participantsStarted 2022-06-01

Plain-language summary

This study aims to evaluate and compare the efficacy of four methods in achieving vertical and horizontal gingival tissue displacement to be captured by optical digital impression. Moreover, the effect of the gingival displacement methods on the periodontal tissues around the final restoration will be assessed.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients having normal occlusion. * Good oral hygiene with no signs of periapical pathology or periodontal disease (plaque index score ≤10). * Clinically and radiographically healthy gingiva and periodontium around the abutments with no evidence of attachment loss. * Thick gingival biotype (determination using color coded probe). * Patient having natural teeth as opposing dentition. * Gingival sulcus of the abutment teeth (≤ 3mm). * Adequate abutment tooth length for retention without deep subgingival extension (not more than 0.5mm) Exclusion Criteria: * Pregnancy, which prevents the use of diagnostic x-rays. * Parafunctional habits. * Mobility of abutment teeth. * Gingival Recession * Patient presenting allergy to materials being used. * Smoking. * Medical history that could affect their periodontal condition.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
