Clinical Performance of Dentals Implants With Hydrophilic or Hydrophobic Surfaces

Brazil44 participantsStarted 2021-04-01

Plain-language summary

The aim of the study is to compare longitudinally the clinical performance of dental implants with different surfaces placed in single tooth gaps at the posterior maxilla and mandible of adults. It is a randomized clinical trial, in which participants will be randomly allocated to two groups: test group (implants with hydrophilic surface) and control group (implants with hydrophobic surface). The null hypothesis is that the implant stability quotient of hydrophilic and hydrophobic dental implants show a similar progression after placement in posterior tooth gaps.

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

Inclusion Criteria: * Present single or multiple intercalated untreated tooth gaps in the posterior region of the mandible or maxilla; * Agree to participate in the study by signing the informed consent form. Exclusion Criteria: * Unavailability for participation or signs that they could not comply with the schedule of follow-up visits; * Presence of general and/or local contraindications that could prevent the surgical procedure for implant placement; * Presence of conditions that may interfere with the prognosis, such as current treatment with bisphosphonates or report of use for less than 2 years, presence of rheumatic diseases, among others; * Absence of the minimum bone quantity of 8 mm in length and 3.75 mm in diameter for installation of an implant in the tooth gap; * Absence of a mesio-distal space of at least 4.6 mm in the single tooth gap required to place the surgical guide; * Do not present a mouth opening of at least 12mm required for the proper of the guided surgical kit together with the surgical guide; * Do not present a band of keratinized tissue favorable for maintaining peri-implant health. * Present motor difficulties that compromise adequate oral hygiene.

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.

What they're measuring

Change of implant stability

Timeframe: 10 time-points will be considered and divided in two phases: surgical and prosthetic. The last measure will occur 1 year after the placement of the definitive implant restoration.
