About this study

Official title: Compraing the Effect of Placement of Collagen Membrane Inside the Extraction Socket and Outside it During Immediate Implant Placement

evaluation of the use of collagen membrane inside the socket and outside it during immediate implant placement

Read the detailed description

Twenty patients, who are candidates for immediate implant placement, will participate in this prospective clinical trial.

Group 1(10 patients) :

immediate implant placement with bone graft and collagen memebrane outside the buccal plate

Group 2 (Control group)(10 patients) :

immediate implant placement with bone graft and collagen memebrane inside the buccal plate assessment of the buccal bone thickness assessment of soft tissue thickness

  • Esthetic outcome evaluation Will be done using the root coverage esthetic score (Cairo et al. 2009) that include

Both evaluations will be done at 3, 6 and 9 months

Being tested
Collagen membrane inside, Collagen membrane outside
Keywords
immediate implant placement, badly decayed tooth in esthetic zone, collagen membrane, xenograft, temporization

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Collagen membrane insideProcedure or surgery

    during immediate implant placement the collagen membrane will be placed in the jumping gap

  • Collagen membrane outsideProcedure or surgery

    during immediate implant placement the collagen membarne will be placed on the surface of the buccal plate of bone

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. buccal plate of bone thickness

    assessment of the buccal plate of bone will be determined in mm from CBCT

    Measured: baseline 12 months

Secondary outcomes (1)
  1. soft tissue thickness (Volumetric assessment)

    Preoperative scanning will be done. At 6,12 months after surgical procedure the same procedure will be done to determine the soft tissue thickness after the surgery. The difference between the tissue thickness before and after

    Measured: baseline, 6 and 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Collagen membrane inside and Collagen membrane outside in people with Immediate Dental Implant Placement and Immediate Implant Placement, run by Ain Shams University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

buccal plate of bone thickness (time frame: baseline 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Feb 2026.
