Summary

The purpose of this study is to see if OsseoSpeed™ implant 6 mm long is effective for rehabilitation of edentulism and if so, how it compares with OsseoSpeed™ implant 11 mm long. The primary hypothesis is that the alteration in bone level is equal in patients randomized to 6 mm as to patients randomized to 11 mm implants.

Eligibility Criteria

Inclusion Criteria

  • Provision of informed consent
  • Aged 20-70 years at enrolment
  • History of edentulism in the study area of at least four months
  • Neighboring tooth/teeth to the planned bridge must have natural root(s)
  • Presence of natural teeth, partial prosthesis and/or implants in the opposite jaw in contact with the planned bridge.
  • Deemed by the investigator to have a bone height of at least 11 mm and a bone width of minimum 6 mm
  • Deemed by the investigator as likely to present an initially stable implant situation

Exclusion Criteria

  • Unlikely to be able to comply with study procedures, as judged by the investigator
  • Earlier graft procedures in the study area

  • History of chemotherapy within 5 years prior to surgery
  • Systemic or local disease or condition that could compromise post-operative healing and/or osseointegration
  • Uncontrolled diabetes mellitus
  • Corticosteroids or any other medication that could influence post-operative healing and/or osseointegration
  • Smoking more than 10 cigarettes/day
  • Present alcohol and/or drug abuse
  • Involvement in the planning and conduct of the study (applies to both Astra Tech staff and staff at the study site)
  • Previous enrolment in the present study.
