Outcome Measures

Primary Outcomes (1)

  • MBL,marginal bone level change

    To evaluate and compare the clinical marginal bone level change (change MBL)in relation to defined implant reference point and different time points in the maxilla and mandible(between baseline at implant insertion and follow-up time points at 1 month, 6 month, 1 year, 2 year, 3 year and 5 year after implant insertion) of observation.

    6 month, 1, 2, 3, 5 year

Secondary Outcomes (7)

  • CSR implants

    6 month, 1, 2, 3, 5 year

  • CSR prosthetics

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The subject is at least 18 years of age (or age of consent) and has passed secession of growth
  • The subject is not older than 70 years
  • Obtained informed consent from the subject
  • Edentulous mandible or maxilla providing sufficient bone whereas removable NobelProceraTM Implant Bar Overdenture on four (4) implants is regarded as an appropriate treatment solution
  • The subject has an osseous architecture enough to receive four implants and a sufficient amount of bone for placing in healed or extraction sites implants with a length of at least 10mm
  • The implant site is free from infection and extraction remnants
  • Implants will be placed in healed or extractions sites, defined as a site with 8 weeks of healing following tooth extraction, respectively 6 months after major bone augmentation or soft tissue grafting
  • Good gingival / periodontal / periapical status of opposing teeth/implants
  • The subject fulfills the prerequisite that a harmonic, stable occlusal relationship can be achieved with opposing natural teeth resp. fixed or removable opposing dentition (tooth or implant based
  • The subjects as well as the implant site(s) fulfill the criteria for early loading (6 weeks until 3 months after implant placement)
  • The subject is in such a physical and mental condition that a 5-year follow-up period can be carried out without foreseeable problems
  • The subject is available for the 5-year term of the investigation
  • The subject is compliant with good oral hygiene

You may not qualify if:

  • The subject is not able to give her/his informed consent of participating
  • Health conditions, which do not permit the surgical (including anesthesia) or restorative procedure
  • Reason to believe that the treatment might have a negative effect on the subject's overall situation (psychiatric problems), as noted in subject records or in subject history
  • Any disorders in the planned implant area such as previous tumors, chronic bone disease or previous irradiation in the head/neck area
  • Alcohol or drug abuse as noted in subject records or in subject history
  • Smoking of \>10 cigarettes/day
  • Uncontrolled diabetes, i.e. a subject with diagnosed diabetes that has a history of neglecting doctor's recommendations regarding treatment, food and alcohol intake
  • Pathologic occlusion, e.g. severe bruxism or other destructive habits
  • Lack of opposing dentition or unstable occlusion
  • Ongoing infections, endodontic or periodontal problems in opposing teeth or implants
  • Subject shows an unacceptable oral hygiene
  • Subject has allergic or adverse reactions to the restorative material.
  • Bone augmentation of more than 3mm vertical height performed less than 3 months prior to planned implant placement.
  • Long-term bis-phosphonate therapy
