Atraumatic Zirconia Abutment Versus Customized Composite Healing Abutment in Maxilla or Mandible.
Latvia44 participantsStarted 2023-02-28
Plain-language summary
40 patients are included in the study, 20 patients in group 1 (=closure with composite material shaper; test group) and 20 patients in group 2 (=closure with custom-made zirconia oxide abutment; control group).
Randomisation envelopes will be used for randomisation. Device under study: Straumann BLX, Roxolid® , SLActive® dental implants with a diameter of 3.5, 3.75, 4, 4.5 mm are used.
Allogenic bone botiss maxgraft® cortical granules are used as graft material.
Inclusion criteria:
1. Males and females at least 18 years of age or older.
2. One implant per patient.
3. Prior to any study-related activity, the subject must voluntarily sign informed consent, be willing and able to attend scheduled follow-up visits, and agree to the collection and analysis of pseudonymised data.
4. Lateral individual teeth (premolars and molars).
5. Class I extraction socket (intact buccal wall) or class II (1/3 of buccal wall).
6. The gingival contour of the tooth to be extracted - without recession.
7. Adjacent anterior teeth have no periodontal loss.
8. There are no implants in the adjacent teeth.
9. Non-traumatic tooth extraction, which results in intact walls of the socket.
Exclusion criteria:
1. Deep occlusion (severe, class II).
2. The patient smokes a lot (more than 10 cigarettes per day).
3. Systemic disease (osteoporosis).
4. No initial stability has been achieved after the implant insertion procedure.

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.
