Clinical and Dimensional Outcomes of Sealing Socket Abutment Combined to Alveolar Ridge Preservation

Belgium20 participantsStarted 2018-08-22

Plain-language summary

objectives The aim of this study was to assess the implant outcomes as well as hard and soft tissue dimensional changes of immediate implant placement in posterior sites using a custom-made sealing socket abutment (SSA) combined to alveolar ridge preservation (ARP). Material and methods Twenty posterior teeth were immediately replaced with implants in 20 patients. The remaining sockets were filled with Deproteinized Bovine Bone Mineral. Based on intra-oral scanners (IOS), custom-made SSAs were placed the same day. CBCT and IOS were performed to monitor hard and soft tissue dimensional changes. Moreover, implant survival rate, peri-implant bone changes, peri-implant health and pink esthetic score were recorded at 1 year, 3years and 5 years.

Inclusion Criteria: * good general health (ASA I/II), * more than 18 years old, * non smoker, * one hopeless tooth, * healthy periodontal condition, * the presence of at least 2 mm of keratinized gingiva, * adequate plaque control (FMPS ≤ 25%), adequate bone quantity in the septum if present and at least 5 mm of bone in the apical region Exclusion Criteria: * auto-immune disease or immunocompromised patients, * uncontrolled diabetes, * use of steroids or biphosphonates, * local or systemic infection (medical treatment needed prior to entrance to the study), pregnancy or breastfeeding, alcoholism or chronically drug abuse. Local exclusion criteria: * bone availability requiring an angulated abutment, * untreated local inflammation, * cyst, * mucosal disease or oral lesions, * local irradiation therapy, * oral communication with sinus after the extraction.

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.
