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

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

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

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Obtained informed consent from the subject.
  • The subject shall be at least 18 years of age and has passed cessation of growth.
  • The subject must be in such a physical and mental condition that a 5-year follow-up period can be carried out without foreseeable problems.
  • The patient is willing and able to comply with all study related procedures (such as exercising oral hygiene and attending all follow-up procedures).
  • The subject requires a single unit implant restoration with guided bone regeneration in bony defects in the anterior and premolar areas of maxilla or mandible.
  • If two or more site single unit implant restorations requiring bone augmentation are required, only one will be included in the study, the other site will be treated with standard of care.
  • The subject shall be healthy and compliant with good oral hygiene.
  • Full-mouth bleeding score (FMBS) lower than 25% [20].
  • Full-mouth plaque score (FMPI) lower than 20% [21].
  • The implant site is free from infection and extraction remnants.
  • The subject shall have a favourable and stable occlusal relationship.
  • Natural roots are adjacent to implant site.
  • The subject is suitable for a 2-stage surgical procedure. Secondary inclusion criteria at time of surgery
  • Sufficient bone volume at the implant site for placing a NobelReplace CC implant.
  • Initial implant stability as assessed by hand testing.
  • Defect size for guided bone regeneration:

Height ≥ 3 mm and ≤ 7 mm as assessed with a UNC15 periodontal probe.

Exclusion Criteria:

  • Previous bone augmentation at the implant site.
  • Extraction site less than 3 months after extraction.
  • Soft tissue grafting at implant placement, soft tissue grafting is allowed only at re-entry.
  • Health conditions, which do not permit the surgical treatment.
  • Any disorders in the planned implant area such as previous tumours, chronic bone disease or previous irradiation
  • Infections in the planned implantation site or adjacent tissue.
  • Acute, untreated periodontitis in the planned implantation site or adjacent tissue.
  • Any ongoing application of interfering medication (steroid therapy, bisphosphonate, etc).
  • Alcohol or substance abuse as noted in subject records or in subject history.
  • Heavy smoking (>10 cigarettes/day).
  • Uncontrolled diabetes, i.e. a subject with diagnosed diabetes that has a history of neglecting doctor's recommendations regarding treatment, food and alcohol intake or A1c level above 8%.
  • Severe bruxism or other destructive habits.
  • Pregnant or lactating women at the time of collagen membrane insertion.

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
Time Frame
To demonstrate bone regeneration through measurement of defect height
Time Frame: 6 months
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
Time Frame
Adverse events (AEs)
Time Frame: 6 months
6 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Primary Completion

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.
