Brief Summary:

The objective of the study is to evaluate the safety and effectiveness of Arestin (minocycline HCl) 1 mg Microspheres in the treatment of subjects with peri-implantitis, when used in combination with mechanical debridement.

The hypothesis of the study is that Arestin in combination with mechanical debridement is more effective in the treatment of peri-implantitis when compared to mechanical debridement alone. The primary efficacy measure will be the reduction of probing depth at Day 180 as measured at qualifying implant sites.

Arm Intervention/treatment
Experimental: Treatment
Treatment (minocycline HCl microspheres, 1mg) administered at Baseline (following randomization) and Day 90 to qualifying implant sites, plus full-mouth mechanical debridement (deep cleaning) at Baseline and Day 180.
Drug: Minocycline HCl Microspheres
Other Name: Arestin (brand name)

No Intervention: Control
Full-mouth mechanical debridement (deep cleaning) at Baseline and Day 180; no treatment

Primary Outcome Measures :
  1. Change in mean Probing Depth of qualifying implant sites [ Time Frame: Baseline to Day 180 ]

Secondary Outcome Measures :
  1. Change in percentage of qualifying implants with Bleeding on Probing [ Time Frame: Baseline to Day 180 ]
  2. Change in mean Probing Depth of qualifying implant sites [ Time Frame: Baseline to Day 90 ]
  3. Change in percentage of qualifying implants with Bleeding on Probing [ Time Frame: Baseline to Day 90 ]
