Bio-implant Root Analogue Versus Conventional Screw-type Implant for Management of Pier Abutment in Mandibular Distal Extension Cases
Egypt8 participantsStarted 2022-12-19
Plain-language summary
reviewing literature was lacking for bio implant and management of pier abutment in distal extension bases for this reason the aim of this research will be to use the bio implant in the management of pier abutment cases for distal extension denture base cases Aim of the study the aim of this study was to evaluate and compare the bioimplant root analogue implant with the conventional screw type implant the evaluation was done 0,3 and 6months of definitive prosthesis insertion regarding the following
1. radiographic evaluation of the alveolar bone hight as related to the bio implant ,conventional screw implant , pier abutment and RPD abutments : this will be done using standardized periapical digital radiographs
2. soft tissue evaluatins related to the bio implant ,conventional screw implant , pier abutment and RPD abutments this will be done using : A . modified plaque index (MPI) B . modified gingival index (MGI) C . peridontal pocket depth

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* The patients had bilateral mandibular free-end partially edentulous cases with a pier abutment or a planned presence of pier abutment.
* The edentulous space mesial to the pier abutment has a hopeless tooth or root that was used for bio-implant insertion or conventional screw-type implants.
* Healthy patients with no systemic disease that can affect the implant surgery. This was verified by medical history in addition to a report from the physician.
* The patients have had dentulous maxillary jaw and mandibular free-end saddle for at least 6 months.
* Class I maxillo-mandibular relationship with adequate inter-arch distance.
Exclusion Criteria:
* Patients with metabolic disorders that affect osseointegration such as uncontrolled diabetes mellitus, immune disorders, and osteoporosis.
* Patients with heavy smoking habit
* Patients complaining of severe temporomandibular joint disorder.
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
