Evaluation of Free Gingival Graft Timing in Staged Guided Bone Regeneration: A Randomized Controlled Trial

This clinical trial aims to compare and evaluate the clinical outcomes between two distinct treatment sequences: free gingival graft surgery preceding guided bone regeneration and guided bone regeneration followed by free gingival graft.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This clinical trial aims to compare and evaluate the clinical outcomes between two distinct treatment sequences: free gingival graft surgery preceding guided bone regeneration and guided bone regeneration followed by free gingival graft. The primary objective is to assess the influence of the tissue graft timing on the outcomes of the guided bone regeneration. The secondary goal is to compare the complications that may arise following the two procedures before implant placement.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

    • Must be able to read and understand the informed consent document.
    • Has a need for implants to replace missing tooth/teeth in at least 1 quadrant of the mouth.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Volumetric outcome assessment
Time Frame: Baseline to 12 months
The volumetric outcomes of interest will be volume change in mm3 (Vol) and the mean distance between the surface/mean thickness of the reconstructed volume in mm.
Baseline to 12 months
Buccal soft tissue profile
Time Frame: Baseline to 12 months
The assessment involves measuring the profile of the buccal soft tissue from the implant shoulder.
Baseline to 12 months

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
