About this study

Official title: Comparison of Dehydrated Human Amnion-Chorion and Type 1 Bovine Collagen Membranes for Guided Bone Regeneration (Socket Augmentation) : A Clinical and Histological Study

The objective of this randomized clinical study was to evaluate the use of dehydrated human amnion-chorion membrane as an exposed barrier for guided bone regeneration (GBR) after tooth extraction and to determine whether intentional exposure of this membrane to the oral environment compromises ridge dimensions and bone vitality for implant placement.

Read the detailed description

Forty-three patients requiring extraction of at least one tooth and delayed implant placement were randomly assigned to either an experimental or a control group. For both groups, demineralized freeze-dried bone allograft was used to graft the socket. For the control group, Type I bovine collagen was used as a membrane; for the experimental group, human amnion-chorion membrane was used. For both groups, the barrier membranes were left exposed, and no primary closure was achieved. Patients returned for implant placement after a mean healing period of 19.5 weeks, at which time a core bone biopsy specimen 2 mm in diameter was obtained for histomorphometric analyses. Clinical ridge dimensions were measured at the times of extraction and implant placement.

Dehydrated Human Amnion Chorion MembraneExperimentalThis membrane was investigated to evaluate its use as an open barrier for guided bone regeneration (GBR) after tooth extraction and to determine whether intentional exposure of this membrane to the oral environment compromises ridge dimensions and bone vitality for implant placement.

Type I Bovine Collagen MembraneActive comparatorThis membrane has been tested as an open barrier for GBR after tooth extraction. The intentional use of this membrane to the oral environment did not compromise ridge dimensions and bone vitality for implant placement.

What is being measured

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

  1. Alveolar Ridge Dimensional Changes

    Clinical ridge height changes were taken with a thermoplastic triad stent, and a University of North Carolina (UNC) 15 periodontal probe. Ridge width changes measurements were taken with a metal bone caliper. Alveolar ridge dimensional changes in height and width were measured at the times of extraction and at the time of implant placement.

    Measured: Alveolar Ridge Dimensional Changes were taken at the extraction time and at the time of implant placement. Mean = 19.5 weeks

  2. Alveolar Ridge Bone Vitality

    a core bone biopsy specimen 2 mm in diameter was obtained from the center of the root at the time of implant placement for histomorphometric analyses

    Measured: Mean= 19.5 weeks after tooth extraction and bone grafting

Secondary outcomes (1)
  1. Ridge Healing Evaluation

    Pictures of the healing ridges were taken using clinical macro lens photography

    Measured: Two weeks form the time of the extraction

Questions about this trial

What is this clinical trial studying?

A study testing Guided Bone Regeneration (GBR) in people with Ridge Deficiency, run by Samer Faraj.

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 3 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 25 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Alveolar Ridge Dimensional Changes (time frame: Alveolar Ridge Dimensional Changes were taken at the extraction time and at the time of implant placement. Mean = 19.5 weeks). The study lists 2 primary outcomes in all. 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 25 Sep 2017.
