Computer Guided Simultaneous Implant Placement With Tri-cortical Ridge Augmentation Using Chin Cortical Bone Struts in Anterior Atrophic Maxilla: A Case Series
Egypt10 participantsStarted 2023-08-27
Plain-language summary
10 patients having deficient anterior maxilla will be recruited and a preoperative CBCT will be done to evaluate the vertical and horizontal dimensions of the intended alveolar ridge. pre-operative manufacturing of the digital surgical guides performed for Harvesting of the chin cortical bone struts from the symphysial area in the donor site and for Placement of the grafted cortical bone struts and the implant in the recipient site. Intra operatively the donor site (Chin) will be prepared to harvest autogenous bone from the chin aided by the patient's prefabricated bone harvesting guide. The recipient site (Maxillary anterior defect) will be prepared to receive the chin grafts. Grafts will be screwed in position and implants will be screwed in its preparation until it gains primary stability from basal bone, using the prefabricated bone fixation-implant placement guide. Any gaps will be filled with autogenous bone particulates from the chin. A healing tie base Abutment will be screwed into the implant through the third cortex.
Primary stability will be assessed using Osstell device. An immediate postoperative CBCT will be done and superimposed on the preoperative CBCT to measure accuracy of plan transfer to make sure the planning was followed accurately.
Follow up after 6 months and CBCT will be done for bone formation and density assessment and implant exposure for implant stability measurement-using osstell and removal Healing abutment and consecutive prosthetic 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.
