Morphological Pattern of the Atrophic Posterior Maxillae

Spain180 participantsStarted 2016-07

Plain-language summary

Overcoming the vertical and horizontal bone deficiency in the posterior maxillae are considered as the most challenging scenarios for implant-supported oral rehabilitation in modern implant dentistry. Therefore, a comprehensive and precise understanding of such anatomical structures are needed to avoid potential complications that ultimately might jeopardize the treatment outcome. Cone-beam computerized tomography (CBCT) offers some advantages to conventional CT-scan such as lower-dose radiation with high isotropic spatial resolution and cost. Therefore, it offers a viable and reliable tool to study anatomical structures such as the posterior atrophic maxillae

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

* Images were included if: 1. Pristine maxillary posterior atrophic ridges (between premolars and molars) as a result of missing single or multiple teeth for over than 12 months. 2. Residual ridge height (RH) was \< 10 mm. 3. Presence of teeth adjacent to or opposing the edentulous area so the location of the edentulous ridges corresponding to the tooth site could be identified. 4. The maxillary sinus to be measured was visible from its floor to at least 15 mm from the alveolar crest of the edentulous ridge. * Images were excluded if: 1. Images were unclear or incomplete due to scattering or other reasons 2. Edentulous ridge height was more than 10 mm 3. Ridge preservation/augmentation simultaneous/delayed to tooth extractions 4. Grafted maxillary sinus for implant-supported prosthesis 5. The location of the edentulous ridge cannot be determined 6. Implants or other prosthetic device restoring the posterior ridge 7. Presence of sinus pathology that made the measurement impossible 8. The outline of the edentulous ridge cannot be identified due to low 'grey scale' density

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.
