Study Type: Interventional

Official Title: Evaluation of Changes of Hard and Soft Tissues After Epi-crestal and Sub-crestal Placement of Ankylos Dental Implants.

Current Primary Outcome: Changes in mid-facial bone levels. [ Time Frame: 18 months and 30 months after implant placement. ]

Changes in mid-facial bone levels to be measured by CAT scan.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Changes of interproximal levels after loading. [ Time Frame: 18 months and 30 months after implant placement. ]
    Measured by periapical radiographs.
  • Changes in buccal soft tissue level. [ Time Frame: 18 months and 30 months after implant placement. ]
    Measured by CAT scan and clinically from a fixed reference point to the mid buccal soft tissue level using a stent.


Original Secondary Outcome: Same as current
