Chart Review: Comparing the Position and Tilt of Dental Implants Versus Those of Natural Teeth
400 participantsStarted 2026-02
Plain-language summary
Background:
When placing a dental implant, it is not always possible to place it exactly in the same position as the tooth that it replaced. That might be because of how the gums and mouth are shaped, since some bone is always lost after a tooth is extracted. Researchers want to study the records of people who have had dental implants. They want to check to see how much difference there is between how the implant is positioned and how the same tooth on the other side is positioned. They also want to compare how the implant is positioned compared to the tooth it replaced, when that is possible in the dental record.
Study design:
This study will not enroll any participants. The researchers will search the database of patient records at the study clinic to find people who have had dental implants of a single molar tooth. Then they will look at them to find records that include good images that they can use to compare the implant and tooth positions.
Researchers will then analyze the findings and write a review article.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients with mandibular molar implant placement.
* Presence of contralateral natural mandibular first, second molars or both.
* Availability of pre-extraction CBCT scans of the corresponding or contralateral mandibular molar tooth or panoramic radiographs for mesiodistal angulation.
* Availability of post-implant CBCT scans or panoramic radiographs for mesiodistal angulation
Exclusion Criteria:
* Incomplete or low-quality CBCT scans.
* History of mandibular trauma or pathologies altering tooth or implant alignment.
* History of reconstructive mandibular surgery in the implant region.
* History of periapical pathology
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.
What they're measuring
1
Replaced Tooth Comparison
Timeframe: Baseline (prior to tooth extraction), day 1 of implant placement, day 1 of crown placement (4-6 months after implant placement)
2
Contralateral Tooth Comparison
Timeframe: Day 1 of implant placement, day 1 of crown placement (4-6 months after implant placement)
