About this study

Official title: Clinical and Optical Evaluation of Self-filling Osmotic Tissue Expander in Augmenting Keratinized Tissue Around Dentulous Region

The present study is a human, prospective, single centre, single blind randomised controlled clinical tria conducted to explore the feasibility and efficacy of self-inflating hydrogel expander (Osmed®) to gain keratinised tissue around the dentulous area. The trial is in accordance to the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.

Read the detailed description

Ten healthy individuals satisfying the inclusion and exclusion criteria were recruited for the study. A detailed, thorough medical and dental history was obtained and each patient was subjected to comprehensive clinical and radiological examination. All patients were informed about the nature of the study, surgical procedure involved, potential benefits and risks associated with the surgical procedure and a written informed consent was obtained from all patients.

All the patients were implanted with self-inflating hydrogel expander (Osmed®) in subperiosteal positions using the pouch technique in the mandibular anterior region. The clinical parameters were recorded at baseline, two weeks post expander retrieval, three months and six months post-operatively.

Osmed® hydrogel expander implantation

What participants receive

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

  • Osmed® hydrogel expander implantationDevice

    Under local anaesthesia, a small vertical incision, adapted to the diameter of the Osmed® sself-inflating hydrogel expander, was made with #15 scalpel blade at the mesial line angle of the adjacent tooth which started below the gingival margin extending from the keratinized tissue above the MGJ to the non-keratinized tissue beyond the MGJ. A minimally invasive preparation of a subperiosteal pouch was performed with KPA tunnelling knife. Size of the pouch was controlled with the specific surgical template to ensure the device easily fits into the prepared pouch without tension. Expanders were secured in the correct position with a bone fixation screw, at the flat end, which does not possess an expansion capability. The wound was closed with 3-0 silk suture using simple interrupted sutures.

What is being measured

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

  1. Keratinized tissue width (KTW)

    measured from the most apical gingival margin to the mucogingival junction (MGJ), with the MGJ location determined using the visual method (Schiller's potassium iodide solution).

    Measured: 6 months

  2. Keratinized tissue thickness (KTT)

    measured at the mid-buccal aspect of the study tooth just below the marginal gingiva using an endodontic file.

    Measured: 6 months

  3. Optical scanning for analysis of tissue thickness

    alginate impressions were made at the baseline prior to expander placement, immediately after the removal of expander and 6 months post-augmentation. The prepared casts were assessed for soft tissue changes by optical scan using 3D camera (Intellidenta AG, Basel, Switzerland). The obtained digital images of the casts reflecting the different treatment time were then superimposed and matched in one common coordinate system. The buccal surfaces of the study teeth were used as a reference point for the superimposition of different images. Subsequently, a defined area of interest at each site were measured and the difference in the linear distance between the time points were calculated.

    Measured: 6 months

Secondary outcomes (3)
  1. Gingival recession depth (GRD)

    measured at the mid-buccal aspect of the study tooth from the CEJ to the most apical extension of gingival margin (using UNC-15 probe)

    Measured: 6 months

  2. Vestibular depth (VD)

    measured from cemento-enamel junction (CEJ) to the deepest part of vestibular mucosa. Measurements were taken with the UNC-15 probe while exerting a firm facial pull on the lip or cheek at a 90° angle to the surface of the teeth.

    Measured: 6 months

  3. Color and texture match to the surrounding tissue

    binary ratings of "equal or not equal to surrounding native tissue" assigned upon clinical examination

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Osmed® hydrogel expander implantation in people with Soft Tissue Augmentation, run by Krishnadevaraya College of Dental Sciences & Hospital.

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 7 inclusion and 8 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 1 Mar 2019. 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?

Keratinized tissue width (KTW) (time frame: 6 months). The study lists 3 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 1 Mar 2019.
