Brief Summary

The goal of this 20-25-year observational study is to investigate the outcomes of bone regenerative surgery in peri-implantitis. Two different techniques will be compared: surgery with a bone substitute alone and surgery with a bone substitute combined with a membrane, to determine their effectiveness and assess whether one is more effective than the other. The intention of this observational study is to learn more about the long-term effects of bone regenerative surgery in patients with peri-implantitis. Patients will be called in for a clinical and radiographic examination of the surgically treated implant(s). Probing pocket depths, presence of pus, bleeding around the implant (s) and a radiograph of the implant (s). To be able to compare with the 1, 3, 5 and 10 year measurements.

Outcome Measures

Primary Outcomes (1)

  • Bone fill

    Radiographic bone fill measured mesial and distal at the implant on an intra oral radiograph. Measurements will be performed by a blinded radiologist.

    Ten years after surgical regenerative boneprocedures

Secondary Outcomes (1)

  • Probing pocket depths changes

    Ten years after surgical regenerative boneprocedures

Other Outcomes (2)

  • Bleeding

    Ten years after surgical regenerative boneprocedures

  • Graded bleeding

    Ten years after surgical regenerative boneprocedures

Study Arms (2)

Group 1

Bone regenerativ surgery with a bone graft material (Algipore) and a resorbable membrane (Osseoquest)

Procedure: Bone regenerative surgery with a bone graft substitute and a resorbable membrane

Group 2

Bone regenerativ surgery with a bone graft material (Algipore)

Interventions

Dental implants with a diagnosis peri-implantitis were treated with regenerative surgery.

Also known as: Bone regenerative surgery with a bone graft substitute

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Patients diagnosed with at least one dental implant with peri-implantitis

You may qualify if:

  • An implant demonstrating a progressive bone loss of ≥3 threads (≥1.8 mm) following the first year of healing
  • A vertical component needed to be present at the surgical intervention in order to justify the use of a bone augmentation procedure.
  • Bleeding on probing and/or suppuration should also be present
