Influence of Neck Design on Peri-implant Hard and Soft Tissues

Spain36 participantsStarted 2016-06-15

Plain-language summary

The goal of this clinical trial is to test two different implant neck designs in 36 patients. The main question\[s\] it aims to answer are: * do triangular neck designed implants placed immediately after dental extraction have the same influence on peri-implant hard and soft tissues than regular neck designed implants at one year? * do triangular neck designed implants placed immediately after dental extraction have the same influence on peri-implant hard and soft tissues than regular neck designed implants at three years? Participants that present an unrepairable tooth on the anterior upper maxilla will be asked to take a CBCT scan in order to verify the presence of the buccal bone. Once this is verified the patients will enter in the study and the day of the surgery they will be assigned to either control or test group. * Control group: C1 round-neck implant * Test groups: V3 triangular-implant neck Researchers will compare test and control groups to see if they have the same effects on hard and soft tissues at 4 months, 1 year and 3 years.

Inclusion Criteria: * healthy non-smokers or light smokers (\< 10 cigarettes/day) * adults (\> 18 years of age), * need for single tooth extraction of a maxillary incisor, canine or premolar * adequate oral hygiene * ability to follow instructions and attend the required appointments * presence of a length of at least 3 mm of buccal bone measuring ≥ 0.5 mm in thickness, apical to the extraction socket * stable and intact socket walls Exclusion Criteria: * patients with acute infections in the area of interest * individuals with large occlusal discrepancies and/or occlusal overload para-functions * smokers of more than 10 cigarettes/day * patients with any medical condition or medication contraindicating dental implant treatment

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.
