Short Implants in Unitary Implant-supported Rehabilitations in the Posterior Maxilla and Mandible: 5 Years of Follow-up

Brazil100 participantsStarted 2026-06-28

Plain-language summary

Implant-supported rehabilitation of regions with severe bone resorption is a challenge for implant dentists. Structures such as the maxillary sinus and the inferior alveolar canal often make it impossible to use implants of lengths considered standard in the literature. The use of short 7 and 8 mm implants with new macrogeometries and surface treatments, in addition to the application of Morse taper prosthetic connections, has shown results that increasingly encourage their use. However, the longevity of these rehabilitations needs to be constantly evaluated. In this work, unitary implant-supported rehabilitations in the posterior jaws, supported by short (7 and 8 mm) tapered Morse connection implants, will be followed for a period of 5 years. A total of 100 subjects rehabilitated with tapered Morse connection implants, with diameters between 3.5 and 4.5 mm, will be evaluated. Peri-implant bone remodeling, implant stability measured through ISQ and clinical parameters will be evaluated per implant and over the evaluation time. Periapical radiographs will be obtained and digitized, analyzed by software and compared with the initial data. The data obtained will be analyzed, allowing longitudinal evaluations and the success rate of implant restorations supported by short implants.

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

Inclusion Criteria: * Individuals (\> 21 years old), of both sexes, specifically rehabilitated with morse connection implants (Implacil De Bortoli, São Paulo, SP, Brazil) in the posterior region of the jaws for single-sided unsupported restorations, will be included in this study. Individuals will also need to have at least initial radiographic controls (immediately after implant placement) and 12 and 60 months of follow-up after implant placement. Individuals will be included in the population sample, with the following criteria observed: location, implant installation region, implant diameter, and adaptation. Exclusion Criteria: * Immediate implants will be excluded, individuals with clinical records who, throughout the study, do not have radiographs for evaluation and/or radiographs of poor quality that make radiographic measurements impossible; medical records with insufficient data, filled out inappropriately or that indicate doubt about the details of the procedure performed.

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
