About this study

In this study patients are randomized to receive either the experimental implant system or the control Nanotite Certain Tapered (standard abutment connection) and assessed for integration success measured by lack of implant mobility and lack of bone loss obtained at various study time points

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • patients of either sex and older than 18 years of age
  • patients needing at least one dental implant to treat partial edentulism
  • patients physically able to tolerate surgical and restorative dental procedures
  • patients agreeing to all protocol visits

Exclusion criteria

  • patients with infection or severe inflammation at the intended treatment sites
  • patients smoking greater than 10 cigarettes per day
  • patients with uncontrolled diabetes mellitus
  • patients with uncontrolled metabolic diseases
  • patients who received radiation treatment to the head in the past 12 months
  • patients needing bone grafting at the intended treatment sites
  • patients known to be pregnant at screening visit
