Evaluation of Trabecular Microarchitecture of the Alveolar Bone by Micro-computed Tomography and of Osseointegration of Dental Implants by Resonance Frequency Analysis

May 18, 2018 updated by: Centre Hospitalier Universitaire de Saint Etienne

Evaluation of Trabecular Microarchitecture of the Alveolar Bone by Micro-computed Tomography and of Osseointegration of Dental Implants by Resonance Frequency Analysis: Correlation Study.

Dental implants are a prosthetic rehabilitation device whose success depends of the bone morphology and quality, in more the surgical procedure.

This study aims to assess whether the parameters of the trabecular microarchitecture of alveolar bone taken from the site of the placement of the dental implant, calculated by micro-CT are correlated with ISQ (implant stability quotient) using the Osstell according the principle of the resonance frequency analysis at the 10th postoperative week during the osseointegration of dental implants (secondary stability).

The cortical alveolar bone is a recognized factor in the phase of primary stability of osseointegration. The role of trabecular bone in the secondary stability is not clearly determined.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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 aim of this study is to check whether the trabecular bone with its microarchitecture plays a predictive role in osseointegration of dental implants precisely in its biological stability phase or its secondary stability phase.

If this correlation is established, a larger study must be conducted to identify a profile of patients at risk for failure of osseointegration of the dental implant.

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

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients who need a dental implant

Description

Inclusion Criteria:

  • affiliated patient or entitled to a social security scheme
  • requiring the installation of one or more dental implants
  • partial or total loss teeth, the height and width od the alveolar bone does not require bone grafting or guides regeneration

Exclusion Criteria:

  • patient who underwent pre-implant surgery (bone grafting, elevation of the maxillary sinus, guided regeneration)
  • patient under corticosteroid therapy in the long term
  • patient who benefited from the head and neck radiotherapy
  • patient under bisphosphonates intravenously treatment
  • all cases immediate implantation and extraction of all implant put into immediate expenses

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
Implant Stability Quotient (ISQ)
Time Frame: 10 weeks
The Osstell is a portable hand instrument used to measure the stability of the dental implant according to the principle of the resonance frequency analysis. It is allow to measure the ISQ.
10 weeks

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.
