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

The patients' treatment will be randomly assigned by coin toss done by the mentor immediately after flap reflection. The examiner will be blinded to the treatment and will not have access to information indicating treatment assignment. The examiner will never see the patient between the time of grafting and complete healing at 4 months. The surgical procedure will consist of the reflection of a split-thickness flap to expose the alveolar ridge. Following complete exposure of the surgical site, vertical measurements will be taken with the acrylic occlusal stent in place, and horizontal measurements with a specially designed digital caliper. After initial surgical measurements, numerous cortical perforations will be performed with a round bur in the area of the augmentation. The control group will receive a block graft and bone screw for stabilization, with voids being filled by the Optecure+CCC®. The test group therapy will include graft with the Optecure+CCC® and the use of Bone Pin® for space maintenance. Horizontal dimension will be established by graft dimensions, bone screws, or bone pins when necessary, for each planned implant area. Longer span edentulous spaces will be divided into individual sites as follows: 5 mm from natural teeth to future mid-implant sites and 7 mm between two future mid-implant sites. The bone pins and bone blocks with bone screws will be placed to allow enough exposure for augmentation to achieve 9 mm horizontal width available for implant placement. Vertical and horizontal measurements will again be taken with the acrylic occlusal stent and calipers prior to flap closure. An resorbable membrane will cover both test and control groups. A monofilament suture material will be used. The surgical procedures will be documented with clinical photographs.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

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
Site width (horizontal) changes by comparing the pre- to post-augmentation dimensions of hard tissues.
Time Frame: 4 months
Measurement of the horizontal changes will be completed with a manual periodontal probe
4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Site height (vertical) changes by comparing the pre- to the post-augmentation dimensions of hard tissues.
Time Frame: 4 months
Measurement of of height will be used with an acrylic stent and a manual periodontal probe.
4 months
Histologic composition of the healed ridge.
Time Frame: 4 month
At the time of re-entry, a trephine core specimen will be taken. This specimen will be examined under a microscope to determine the vital bone characteristics.
