All-on-X Stackable Guides for Maxillary Terminal Dentition

Egypt40 participantsStarted 2024-01-01

Plain-language summary

This retrospective study will evaluate the clinical performance of maxillary All-on-X(full-arch implant-supported rehabilitation) implant rehabilitation using stackable guided surgery and immediate loading. Implant survival and peri-implant outcomes will be assessed over a 2-year follow-up, with regression analysis will be used to investigate the influence of surgical and prosthetic variables, including basal seating guide design.

Inclusion Criteria: Adult patients presenting with terminal dentition of the maxillary arch Rehabilitation with a maxillary All-on-6 implant-supported complete fixed dental prosthesis Treatment performed using a fully digital stackable guided surgery workflow Immediate loading with a provisional fixed prosthesis Availability of complete clinical and radiographic records Minimum follow-up period of 2 years Prosthetic design classified as (Fixed prosthesis) FP-1 or FP-2 according to Misch classification Exclusion Criteria: Uncontrolled systemic conditions contraindicating implant surgery History of head and neck radiotherapy Presence of untreated periodontal or peri-implant infection at the time of surgery Incomplete or missing clinical or radiographic records Cases requiring simultaneous bone grafting procedures Severe maxillary atrophy (Cawood and Howell Class III-V) Cases requiring FP-3 prosthetic design Rehabilitation performed without guided surgery or without immediate loading

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.
