Customized CAD/CAM Titanium-Milled Abutments Vs. Custom Abutments Over Immediate Implants in Class II Extraction Sockets in the Esthetic Zone: a Randomized Controlled Clinical Trial

Egypt48 participantsStarted 2024-01-22

Plain-language summary

Background: Immediate implant placement in esthetic zones, particularly Class II and III extraction sockets, presents challenges related to soft and hard tissue changes post-extraction. Customized abutments may offer advantages over stock abutments in managing these changes and improving clinical outcomes. Objective: This study aims to evaluate the comparative effectiveness of customized cad cam titanium milled abutments versus stock abutments on dental implants in Class II extraction sockets in terms of soft and hard tissue integration and aesthetic outcomes. Methods: A randomized controlled clinical and radiographic trial will be conducted at the Oral Medicine, Periodontology, Oral Diagnosis, and Radiology Department of Tanta University. Forty-eight patients requiring immediate implants in the maxillary anterior region will be randomly assigned to receive either a stock abutment or a customized titanium milled abutment. All implants will be placed using a computer-assisted surgical guide and treated with a collagen plug. Clinical and radiographic evaluations will be performed at baseline, 6 months, and 12 months, utilizing intraoral scanning and cone beam computed tomography (CBCT) to assess peri-implant mucosal levels and crestal bone thickness.

Inclusion criteria

. Adults (20 -50)
. Patients will be included if they have one or more of hopeless teeth without signs of acute infection in the maxillary anterior region.
. Remaining roots or non-restorable teeth with sufficient bone apically and palatably to allow proper implant positioning with sufficient primary stability.
. Optimal compliance as evidenced by no missed treatment appointments and a positive attitude towards oral hygiene.
. Medically-free

Exclusion criteria

. Medically compromised patients and systemic conditions precluding implant and periodontal surgery.

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.
