The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Dentsply Sirona Implants
  Purpose
The purpose of this study is to evaluate the outcome of implant OsseoSpeed EV compared to implant OsseoSpeed TX with regards to marginal bone level changes and implant survival rate up to five years after implant loading. The hypothesis is that there will be no clinically relevant differences in marginal bone level alterations one year after functional loading.

Condition Intervention
Partial Edentulism in the Maxilla or in the Mandible Device: OsseoSpeed EV Device: OsseoSpeed TX

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open, Prospective, Randomized, Multicenter Study Comparing OsseoSpeed™ EV With OsseoSpeed™ TX in Partially Edentulous Maxillae and Mandibles. A 5-year Follow-up Study.

Further study details as provided by Dentsply Sirona Implants:

Primary Outcome Measures:
  • Marginal Bone Level [ Time Frame: 12 months after implant loading ]
    Marginal bone level will be determined from radiographs and expressed as the distance from a reference point on the implant to the most coronal bone-to-implant contact on the mesial and distal aspect of the implant. Marginal bone level expressed in millimeters at the 12 months follow-up visit will be compared to values obtained at delivery of permanent restoration i.e. loading (baseline). Positive value denotes gain of bone. Negative value denotes loss of bone.


Enrollment: 120

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Provision of Informed Consent.
  2. 18 -75 years at enrollment.
  3. In need of implant(s) replacing missing tooth/teeth in the maxilla or in the mandible (no edentulous jaws).
  4. History of edentulism in the planned implant area of at least 3 months (at Visit 2).
  5. At least 4 months of healing after last grafting procedure in the planned implant area (at Visit 2).
  6. Deemed by the investigator to be suitable for one stage surgery and be likely to present an initially stable implant situation i.e. have a bone height and bone width suitable for the chosen study implants.
  7. Deemed by the investigator to be suitable for loading after 6-8 weeks.
  8. Deemed by the investigator to have a "functional" opposing dentition at the time of loading the implants i.e. an even distribution of contacts between the teeth in the opposite jaw and the planned permanent crown/bridge.

Exclusion Criteria:

  1. Unlikely to be able to comply with study procedures, as judged by the investigator.
  2. Uncontrolled pathological processes in the oral cavity.
  3. Untreated, uncontrolled caries and/or periodontal disease.
  4. Known or suspected current malignancy.
  5. History of radiation therapy in the head and neck region.
  6. History of chemotherapy within 5 years prior to surgery.
  7. Systemic or local disease or condition that would compromise post-operative healing and/or osseointegration, as deemed by the investigator.
  8. Uncontrolled diabetes mellitus.
  9. Corticosteroids or any other medication that would compromise post-operative healing and/or osseointegration.
  10. Smoking more than 10 cigarettes per day.
  11. Present alcohol and/or drug abuse.
  12. Current need for bone grafting and/or augmentation in the planned implant area. Local, minor soft tissue grafting will be allowed.
  13. Involvement in the planning and conduct of the study (applies to both Astra Tech staff and staff at the study site).
  14. Previous enrollment in the present study.
  15. Simultaneous participation in other clinical studies at enrollment (Visit 1) and during the subject's first year of this study.
