Bone Quality and Quantity Following Guided Bone Regeneration Prior to Dental Implant Placement

November 26, 2017 updated by: Hadassah Medical Organization

Bone Quality and Quantity Following Guided Bone Regeneration With Bio-Oss Alone or Combined With BondBone, Prior to Dental Implant Placement

Amongst the consequences of missing teeth are change of appearance and difficulties in mastication and speech. Dental implants in the maxilla or mandible provide a common treatment modality by offering anchorage to fixed or removable fixtures. In many cases, the lack of teeth is accompanied by lack of appropriate bone volume in the desired area for dental implant placement. Possible causes for this lack of sufficient bone volume are varied and include earlier bone atrophy, traumatic tooth extraction and bone resorption due to periodontal disease. In such cases, dental implant placement is preceded by alveolar bone augmentation . Guided Bone Regeneration (GBR) is a common bone augmentation technique in which a bulk of bone substitute is placed in the area which needs more volume before placing a dental implant. The bone substitute is covered with an inert membrane and may provide a scaffold and encourage cells from the patient to reach the area and build new bone volume. A common bone substitute in use for that matter is Deproteinized bovine bone mineral (DBBM) which resembles human bone and helps encourage new bone formation. On the contrary its structural stability during placement and early healing is low. Bi-Phasic Calcium-Sulphate is another common bone substitute with easy handling properties and good structural stability during early healing. Its replacement by natural bone contributes to the augmentation process. Although DBBM efficacy in GBR process has been investigated, using DBBM in combination with bi-phasic calcium-sulphate as a binding material during GBR was not examined. This prospective study will examine augmented bone quality and quantity following a GBR procedure with common approved bone substitutes: DBBM (Bio-Oss, Geistlich) alone or in a combination with bi-phasic Calcium-sulphate (BondBone, Augma). The GBR procedures will precede dental implant placement as custom. The quality and quantity of the new formed bone will be assessed by a C.T (computerized tomography) which is done routinely before dental implant placement and by further analyses of bone residues which will follow drilling the dental implant placement site while preparing it (as common).

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.

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.

Intervention / Treatment

Experimental: Bio-Oss
In this arm,GBR will be performed with DBBM (Bio-Oss, Geistlich) in 25 patients.
Device: Bio-Oss (by Geistlich)
Guided Bone Regeneration (GBR) will be done with no changes from the common (Dahlin 1988). Patients will be given local anasthesia, full thickness mucoperiosteal flap will be raised to expose the bone area that needs augmentation, bone substitute will be placed over the bony crater and covered with a collagen membrane (Bio-Gide, geistlich, FDA and CE approved). Mucoperiosteal flap will be sutured and patients will be instructed to a check-up routine as accepted after this kind of procedure.

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
Volume of the new bone formed after a GBR procedure
Time Frame: Volume of the new bone formed after the GBR procedure will be determined up to 7 months after the GBR procedure and before the insertion of dental implants.
Bone volume obtained following a GBR procedure will be detemined through a comparison of a 3 dimensional analysis of computed tomography images done before and after the GBR procedure.
Volume of the new bone formed after the GBR procedure will be determined up to 7 months after the GBR procedure and before the insertion of dental implants.

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
Bone quality
Time Frame: Bone quality will be assesed through histological analysis that will be carried out at the time of implants insertion (up to 8 months following the GBR procedure).
The collected bone sample will be subjected to histo-morphometric analysis in order to determine the size, shape and orientation of the bony trabeculae,the size and porosity of the bony cortex in addition to the new bone/ bone substitute ratio.
Bone quality will be assesed through histological analysis that will be carried out at the time of implants insertion (up to 8 months following the GBR procedure).
