Impact of a Alveolar Ridge Preservation Technique on the Need of Performing Guided Bone Regeneration for Dental Implant Placement

March 4, 2020 updated by: Simone Lumetti

Impact of Alveolar Ridge Preservation on Optimal Implant Placement

The aim of this study is to investigate how a socket preservation procedure may reduce the need of guided bone regeneration surgery after tooth extraction and facilitate the placement of a dental implant in the optimal, prosthetic-driven position.

Study Overview

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 main gol of the study is to assess the efficacy of a socket preservation procedure in reducing the need of additional surgeries in order to augment alveolar bone volume before placing a dental implant in optimal position. Bone volume at 6 months will be compared to initial volume in order to assess volume variations and how they affect the positioning of a prosthetically driven, implant.

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)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Alveolar Ridge Preservation
Patients in this arm will undergo atraumatic extraction of an hopeless tooth and a socket preservation procedure. Alveolar ridge preservation will be performed using a slow-resorption bone substitute and a collagen membrane that covers the graft.
Procedure: Tooth extraction and Alveolar ridge preservation
Tooth extraction and alveolar ridge preservation with deproteinized bovine bone mineral and a collagen matrix seal
Other Names:
  • Socket preservation
Active Comparator: Natural healing
Patients in this arm will undergo atraumatic extraction of an hopeless tooth. The socket will follow natural healing.
Procedure: Tooth extraction
Tooth extraction and socket natural healing
Other Names:
  • Socket natural healing

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
Number of implants ideally placed
Time Frame: 6 months
The main goal is to determine if alveolar ridge preservation affects optimal implant positioning. This is defined as the implant position allowing to fulfill the ideal prosthetic design of the crown to be restored.
6 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
Peri-implant bone variation
Time Frame: 6 months
Crestal bone levels (CBL): distances from the implant shoulder to the most coronal bone to implant contact measured on X-rays with a millimeter ruler to the nearest 0.5 mm. Two measurements will be taken for each implant: mesially and distally
6 months
Ridge volume at 6 months after tooth extraction
Time Frame: 6 months
The comparison of baseline and control cone.beam computed tomography and of clinical data in test and control groups will allow to determine volumetric effects on bone and soft tissues of socket preservation.
6 months
