简要总结

The purpose of this study is to evaluate the outcome of prosthetic survival of the Acuris conometric concept 1 year after permanent restoration, since this is a new mode of retention using friction for seating the crown of single tooth restorations without using cement or screws.

  • Neighbouring tooth to the planned implant must have
  • a natural root or an implant supported restoration mesially
  • a natural root or an implant supported restoration distally Exemption: If the planned implant is in the second molar position, an edentulous space is accepted distally.
  • Presence of natural tooth, partial prosthesis and/or implant supported restoration in the opposite jaw in contact with the planned crown
  • Deemed by the investigator as likely to present an initially stable implant situation

排除标准

  • Unlikely to be able to comply with study procedures, according to Investigators judgement
  • Subject is not willing to participate in the study or not able to understand the content of the study

  • Simultaneous participation in another clinical study, or former participation in a clinical study during the last 6 months that may interfere with the present study
  • Previous enrolment in the present study
  • Uncontrolled pathological process in the oral cavity
  • Known or suspected current malignancy
  • History of radiation therapy in the head and neck region within 12 months prior to surgery
  • Systemic or local disease or condition that could compromise post-operative healing and/or osseointegration
  • Uncontrolled diabetes mellitus
  • Corticosteroids, iv bisphosphonates or any other medication that could influence post-operative healing and/or osseointegration
  • Current need for major bone grafting and/or augmentation in the planned implant area (minor grafting and soft tissue grafting are allowed)

结局指标

主要结局

Prosthetic Survival

时间窗: 1 year after permanent restoration

Evaluation of presence of original permanent restoration, remained retention between abutment and final cap, and occurrence of fracture/loss of abutment. Prosthetic survival will be categorized as No/Yes. It will be categorized as "Yes" if all of the following criteria are fulfilled: * Permanent restoration is remaining in situ. * No loss of conometric retention between abutment and final cap. * No fracture of abutment. * No loss of abutment.

次要结局

  • Implant Survival(1, 3 and 5 years after permanent restoration)
  • Prosthetic Survival(3 and 5 years after permanent restoration)
  • Bleeding on Probing(1, 3 and 5 years after permanent restoration)
  • Marginal Bone Levels Alterations(1, 3 and 5 years after permanent restoration)
  • Plaque(1, 3 and 5 years after permanent restoration)
  • Probing Pocket Depth(1, 3 and 5 years after permanent restoration)
