Differences Between Two Type Implants in Post-extraction Alveolus

Portugal20 participantsStarted 2017-06-01

Plain-language summary

One of the challenges of current implantology involves the preservation or reduction of existing bone resorption, mainly in the buccal bone plate, after tooth loss, which becomes of special importance in the anterior region of the maxilla (aesthetic region). The study evaluates the macroscopic shape of neck implant influence in the results of immediate implants, in a population comprised of individuals from the clinic of the Faculty of Dental Medicine of the University of Porto in need of replacement of a single tooth. It is intended to evaluate the morphometric (direct measures and plaster models measurements), imaging, and photographic characteristics of the V3 implant in comparison with the C1 implant of Mis® by an evaluation period of 6 months when placing an immediate implant.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients aged 18 and over * Patients with understanding and free decision-making for informed consent * Patients who need rehabilitation of a tooth in the region of incisors, canines, or maxillary premolars * Patients with EDS-1 or EDS-2 dental sockets, according to Caplanis N. classification. Exclusion Criteria: * Patients with systemic pathologies that contraindicate the surgical procedure; * Prolonged Non-steroidal anti-inflammatory drugs (NSAIDs); * Bisphosphonate therapy; * Lack of opposing teeth on implant site; * Lack of adjacent teeth on implant site; * Dental-sockets with total loss of one of the cortical; * Untreated periodontal pathology; * Pathology or circumstance that prevents patients from attending routine check-ups; * Patients who smoke more than 10 cigarettes/day. Smokers are advised to reduce or stop smoking.

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.
