Influence of the Primary Stability and Temporary Prosthetics

90 participantsStarted 2026-05-07

Plain-language summary

The goal of this clinical trial is to to determine how different primary implant stability and loading management affect implant osseointegration and further function after one year. The main questions it aims to answer are: is primary stability of inserted implant needed for implant integration? Does primary stability and restoration mode of the implant influence marginal bone stability of that implant? Researchers will compare crestal bone levels and primary stability of the implant after insertion in 3 groups. Subjects will be assigned to groups, acoording to primary stability developed during insertion of the implant. Study groups - (1) If stability is low (5-10 N/cm), Megagen BlueDiamond implants will be inserted, and a temporary prosthesis will not be placed; the implant will be sutured; (2) If stability is moderate (15-35 N/cm), Megagen BlueDiamond implants will be inserted, and a custom plastic gingiva-forming healing abutment will be placed; (3) If stability is high (40 N/cm and higher), Megagen BlueDiamond implants will be inserted, and a temporary plastic crown will be placed. Primary outcome of the study will be implant integration, secondary ourtcomes - implant insertion depth during insertion and after osseointegration, marginal bone stability after prosthesis delivery and after one year, determination of the PES (pink esthetic score) index after prosthesis delivery and after 1 year, determination of the ISQ value after implant insertion and after osseointegration, changes in gingival volume around the implants after 1 year, determination of the Plaque Index (PI) after prosthesis delivery and after 1 year, determination of the Probing Pocket Depth (PPD) after prosthesis delivery and after 1 year, determination of the Bleeding on Probing (BOP) index after prosthesis delivery and after 1 year.

Inclusion Criteria: * ≥ 18 years old. * healthy patients without medical contraindications for dental implantation surgery. * removable and non-molar teeth indicated for extraction in both jaws * healthy soft tissues (bleeding on probing \< 20%, plaque index \< 25%); * intact alveolar bone walls post-extraction * signed informed consent form and permission to use the obtained data for research purposes. Exclusion Criteria: * Smokers (≥ 10 cigarettes per day); * history of uncontrolled periodontitis; * uncontrolled diabetes/alcoholism; * use of drugs that may affect healing; * persons who, due to health status, cannot be considered capable of reasonably assessing their interests;

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.
