Association Between Restorative Emergence Profiles and Peri-implant Bone Loss in Different Implant Systems:

Lebanon76 participantsStarted 2022-12-01

Plain-language summary

The goal of this observational study is evaluate the association between different emergence profile angulation on marginal bone loss progression around different implant systems (bone level, tissue level and switching platform). Does different emergence profile angulation have the same effect on peri-implant marginal bone loss? Standardized periapical radiograph that were captured after crown placement on implants will be compared with the new radiographs done after recalling the patient.

Inclusion Criteria: * Patients who have undergone the initial phase followed by implant placement. * Implants placed and prosthesis delivered for more than 3 years. * Implants placed in premolar/molar region * No reconstructive bone procedure done on the site of study * Presence of opposing occlusion * Non-smokers Exclusion Criteria: * Systemic diseases (uncontrolled diabetes, drugs that can affect bone metabolism). * Total edentulousness. * Inappropriate, unavailable, or distorted x-rays. * Implants placed at a supra or infra bone level. * Implants placed immediately after an extraction. * Poor oral hygiene (High plaque score FMPS control record \> 30%) * Smokers * Signs of peri-implantitis development during the first year following functional loading * Lack or incomplete information regarding peri-implant conditions (clinical and radiographic documentation at the required study time-points) * Surgical treatment on the study implants during the first 2 years after peri-implantitis diagnosis

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.
