A two-arm, parallel group, randomized controlled clinical trial on adult human subjects receiving divergent or concave Atlantis™ abutments to assess peri-implant mucosa changes from prosthesis delivery to 1 year.
- (Primary) Compare the influence of experimental concavities in the subgingival transition zone of Atlantis™ abutments on peri-implant mucosal dynamics from final restoration delivery to one year, as compared to current Atlantis™ abutments with linear divergent transition profiles.
- (Secondary) Quantify the horizontal soft tissue thickness changes around concave and divergent abutment transition profiles from final restoration delivery to one year.
- (Secondary) Evaluate changes in peri-implant health indicators, such as Gingival Index (GI), Probing Pocket Depth (PPD), and Bleeding on Probing (BOP).
If you are currently missing a single tooth located on your upper jaw you may be eligible to participate in a study comparing two dental prosthetic parts. You will receive a dental implant and the corresponding prosthetic parts at reduced cost if you are eligible. You must meet the eligibility criteria below:
- Be 18 years old or older
- Have good oral health
- Require a replacement tooth in the upper jaw from first premolar to first premolar on either side (the first premolar is one tooth behind your canine, also known as the eye tooth)
- Have stable natural teeth directly adjacent and opposing the site of interest
- Be a non-smoker with no current alcohol or drug abuse
- Not have uncontrolled diabetes or any other significant chronic condition
- Not currently taking corticosteroids or bisphosphonates
- Not currently pregnant or wish to become pregnant in the next year
