Study on OsseoSpeed™ Implants in Patients Missing 2-5 Teeth in the Posterior Lower Jaw, Restored With Permanent Teeth Attached 6-7 Weeks Later
Study Details
Study Description
Brief Summary
The purpose of the study is to evaluate Astra Tech Dental Implant System, Fixture Osseospeed™, in patients with tooth loss in the posterior mandible in an early loading protocol. Primary objectives are implant stability, marginal bone adaptation and survival rate.

Outcome Measures
Primary Outcome Measures
- Implant Survival Rate [At 5 year follow-up]
An implant that has failed to osseointegrate, lost its osseointegration or fractured will be considered a failure effective from the date of removal. The survival rate for individual implants will be analyzed at each visit. Cumulative implant survival rate will be calculated using Kaplan-Meier life-table estimation and reported as percentage of survived implants.
- Implant Stability [At 1 year follow-up]
Implant stability will be evaluated using Resonance Frequency Analysis (RFA). The RFA value is automatically translated into an Implant Stability Quotient index (ISQ), which runs from 1 to 100.
- Marginal Bone Adaptation [At 5 year follow-up]
Marginal bone adaptation will be expressed as the distance from the implant reference point to the most coronal bone-to-implant contact on the mesial and distal side of the implant. Bone adaptation in millimeters at follow-up visit will be compared to values obtained Baseline (loading). Positive value indicates bone gain and negative value bone loss.
Eligibility Criteria
Criteria
Inclusion Criteria:

Need for systemic corticosteroids or any other medication that would compromise post-operative healing and/or osseointegration
-
Present alcohol or drug abuse
-
Unable or unwilling to return for follow-up visits for a period of 5 years
