About this study

Official title: Phase I/II Trial of Alveolar Bone Engineering Using Bioactive Glass (Sol-Gel) Immediately After Premolar Extraction in Patients Requiring Orthodontic Treatment

The purpose of the present research is to evaluate the effect of bioactive glass in bone regeneration immediately following extraction of mandibular and maxillary premolars.The hypothesis of the study assumes that this treatment would promote the healing of the extraction socket while preserving both the height and width of the bone. Furthermore, it would allow more effective tooth movement during orthodontic treatment.

Read the detailed description

Bioactive glass has long been known as a bone graft substitute capable of bone augmentation. The current proposal introduces a newly tailored bioactive glass scaffold with multi-scale porosity prepared using the sol-gel technique to regenerate bone in extraction sockets with the aim of preserving the alveolar ridge. This novel material has the potential to enhance angiogenesis and osteogenesis thereby preserving the overall height and width of the alveolar bone by regenerating new bone that closely mimics the adjacent healthy one. Thirty patients requiring myofunctional therapy including premolar extraction as part of a two stage orthodontic treatment (class II division I) will be enrolled in this phase I/II clinical study. Patients will undergo extraction of their maxillary and mandibular premolar teeth. This will serve as a split-mouth study where on one side the extraction sockets will be left empty while on the other side they will receive the bioactive glass as a bone graft substitute. Clinical and radiographic assessment of healing will be performed at the following time intervals; 1,2,4,12,24 weeks. Clinical criteria will include scoring for pain, inflammation, and occurrence of any post-operative complications using a well-defined scoring system. Radiographic assessment will monitor the changes in crestal bone height and bone mineral density. Computed tomographic scans will also be taken preoperatively and at 6 months for each patient for 3D assessment of bone changes. A core biopsy will also be taken after informed consent at the 6 months time-point to evaluate the quality and quantity of new bone formed.

What is being measured

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

  1. Change in Alveolar Crestal Bone Height

    The primary objective of the study is to determine the effect of using bioactive glass in preservation of alveolar crestal height and width surgical sockets immediately after premolar extraction assessed at baseline, 1,2,4,8,12,24 weeks post-extraction, baseline ,4 and 12 weeks reported. This change was analyzed by subtracting the values of each interval from the baseline values.the positive values indicate that the alveolar crest is coronal to the cemento enaml junction (reference point) , while the negative values indicate that the alveolar crest in apical to the cemento enamel junction (reference point)

    Measured: assessed at baseline, 1,2,4,8,12,24 weeks post-extraction, baseline,4 and 12 weeks reported.

  2. Bone Mineral Density

    The primary objective of the study is to determine the effect of using bioactive glass in inducing alveolar bone regeneration safely and effectively in surgical sockets immediately after premolar extraction assessed at baseline, 1,2,4,8,12,24 weeks post-extraction, baseline,4 and 12 weeks reported.

    Measured: assessed at baseline, 1,2,4,8,12,24 weeks post-extraction, baseline,4 and 12 weeks reported.

Questions about this trial

What is this clinical trial studying?

A study testing bioactive glass (sol-gel) and empty extraction socket in people with Bone Loss and Vertical Alveolar Bone Loss, run by Alexandria 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 6 inclusion and 7 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 2020. 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?

Yes. Results are posted in the registry (first posted 18 Feb 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

What does the primary outcome measure?

Change in Alveolar Crestal Bone Height (time frame: assessed at baseline, 1,2,4,8,12,24 weeks post-extraction, baseline,4 and 12 weeks reported.). 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?

On the ClinicalTrials.gov record for NCT01878084, which also lists 1 linked publication.

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.
