Evaluation of Implant Abutment-Level Digitalization Techniques

Turkey (Türkiye)12 participantsStarted 2025-03-21

Plain-language summary

This methodological clinical study aims to evaluate digital workflows used for the intraoral digitalization of cement-retained implant abutments in situations where implant impression components are unavailable and abutment replacement is not feasible. Three digital impression workflows were compared through quantitative analysis of three-dimensional implant positions derived from digital datasets obtained using scan bodies and abutment-level scans. Implant positions were defined by virtual implant axes and analyzed using reverse engineering software. The study evaluates whether combined intraoral-extraoral abutment scanning provides comparable accuracy to direct intraoral abutment scanning.

Inclusion Criteria: 1\. Voluntary participation in the study after reading and signing the informed consent form 2. Adult patient over the age of 18 who has completed growth and development 3. Having healthy dental and periodontal conditions 4. Presence of partial edentulism in the functional region requiring two-implant-supported restorations with two or three occlusal units 5. Having a fixed dentition in the arch with edentulism 6. Having a fixed dentition in the opposing arch 7. No need for vertical or horizontal prosthetic correction in the interarch occlusal relationship 8. Presence of bone-level implants placed with "straightforward" surgical approach (as defined by the SAC classification system \[195\]), without advanced surgical techniques \- Exclusion Criteria: 1\. Refusal to participate voluntarily in the study after reading the informed consent form 2. Presence of any absolute contraindication to implant treatment (e.g., history of radiation therapy, bone cancer, metabolic disorders) 3. Presence of systemic risk factors for implant treatment (e.g., steroid therapy, uncontrolled diabetes, immunological disorders, pregnancy) 4. Presence of local risk factors for implant treatment (e.g., periodontal disease, bruxism, poor oral hygiene) 5. Presence of temporomandibular joint disorders that limit jaw movements \-

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.
