Intervention Model: Parallel Assignment

Primary Outcome Measures:
  • Overall PD Reduction [ Time Frame: Baseline to Day 180 ] [ Designated as safety issue: No ]
    Mean reduction of probing depth (PD) of qualified implant sites is derived by calculating the change of PD per qualified implant site (PD at baseline minus PD at post-baseline), and then averaging the site-specific PD changes per subject


Secondary Outcome Measures:
  • Initial PD Reduction [ Time Frame: Baseline to Day 90 ] [ Designated as safety issue: No ]
    Mean reduction of probing depth (PD) of qualified implant sites is derived by calculating the change of PD per qualified implant site (PD at baseline minus PD at post-baseline), and then averaging the site-specific PD changes per subject

  • BOP Percent Reduction From Baseline [ Time Frame: at Day 90 and Day 180 ] [ Designated as safety issue: No ]
    Bleeding on Probing (BOP) percentage is calculated as the number of implant sites with bleeding divided by the number of implant sites per subject times 100% at each visit; reduction of BOP percentage is the BOP percentage at baseline minus the BOP percentage post-baseline


Enrollment: 44
Study Start Date: April 2008
Study Completion Date: April 2009
Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Minocycline HCl
1 mg microspheres of minocycline hydrochloride
Drug: Minocycline HCl
1mg microspheres for professional subgingival administration into periodontal pockets two times throughout the duration of the trial
Other Name: antibiotic
No Intervention: No Intervention
Control group receiving no drug intervention

Detailed Description:

At Visit 1, the dentist will:

  • do an oral exam
  • ask some questions
  • decide if the person qualifies for being in the study
  • make an appointment for Visit 2 if they qualify

At Visit 2 (Baseline), the dentist will:

  • do a special cleaning of the implants
  • examine the whole mouth
  • collect some fluid
  • take x-rays
  • put the people into one of two groups (taking into account whether or not they smoke)

    1. one group will have the study antibiotic put on all the areas in their mouth with gum problems
    2. the other group will not receive the antibiotic At Visit 3 (about a month later), only fluid samples will be collected.

At Visit 4 (about 3 months later), the dentist will:

  • collect fluid samples
  • examine the whole mouth
  • apply the antibiotic again for people in that group

At Visit 5 (about 6 months later), the dentist will:

  • collect fluid samples
  • examine the whole mouth
  • take x-rays
