Clinical Outcomes of Resective Surgical Treatment of Peri-Implantitis With or Without Implantoplasty

January 7, 2021 updated by: Hom-Lay Wang, DDS, MSD, Ph D, University of Michigan

Clinical Outcomes of Resective Surgical Treatment of Peri-Implantitis With or Without Implantoplasty. A Retrospective Study

The aims of the current study are 1) to assess the therapeutic resolution of the peri-implantitis after resective surgical treatment with or without implantoplasty procedure (no further radiographic bone loss, no erythema of the peri-implant mucosa, PD <6mm), and 2) to evaluate the survival rate of the peri-implantitis treated dental implants.

Detailed Description

The records of patients who underwent resective surgical treatment for peri-implantitis at the University of Michigan Graduate Periodontics clinic will be examined and analyzed. Patients who meet the inclusion/exclusion criteria will be contacted and invited to participate in the study to measure the following in a single visit: bleeding on probing, edema, redness of the peri-implant mucosa, and peri-implant probing pocket depth. Additionally, patients will be asked to complete a survey during their study visit regarding their implant(s) and previous peri-implantitis.

Study Population

Patients who underwent resective surgical treatment for peri-implantitis at the University of Michigan Graduate Periodontics clinic from January 1, 1990 through July 1, 2018

Description

Inclusion criteria:

  1. The patient is at least 18 years of age,
  2. was initially diagnosed with peri-implantitis at ≥1 implant (peri-implant probing depth (PPD) ≥ 6 mm together with bleeding and/or suppuration on probing (BOP/SoP) and bone loss progression over physiological bone remodeling radiologically assessed or marginal bone loss ≥ 3 mm radiologically assessed in case of absence of baseline radiographs),
  3. had received treatment for peri-implantitis at least 1 year ago at the Graduate Clinic of Periodontics at University of Michigan, and
  4. documentation from ≥ 1 year of clinical and radiological follow- up is available from U of M patients records.

Exclusion criteria:

  1. Has received or is currently receiving radiotherapy,
  2. are currently pregnant, unsure of their pregnancy status, or are lactating (as reported by the patient),
  3. has health condition(s) or takes medication(s) that are known to affect soft tissue or bone (e.g., Phenytoin)
  4. Received any kind of bone graft during the treatment of the peri-implantitis

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Therapeutic resolution of the peri-implantitis as measured by radiographic bone loss
Time Frame: Up to 30 years after the implant was treated for peri-implantitis
The implant has no further radiographic bone loss when compared to previous radiographs.
Up to 30 years after the implant was treated for peri-implantitis
Therapeutic resolution of the peri-implantitis as measured by erythema
Time Frame: Up to 30 years after the implant was treated for peri-implantitis
The implant has no current erythema of the peri-implant mucosa.
Up to 30 years after the implant was treated for peri-implantitis
Therapeutic resolution of the peri-implantitis as measured by probing depths
Time Frame: Up to 30 years after the implant was treated for peri-implantitis
The implant has probing depths less than or equal to 5 millimeters.
Up to 30 years after the implant was treated for peri-implantitis
Survival rate of the peri-implantitis treated dental implants
Time Frame: Up to 30 years after the implant was treated for peri-implantitis
Survival rate will be determined by the duration of implant survival (functioning, non-symptomatic implant after peri-implantitis treatment).
Up to 30 years after the implant was treated for peri-implantitis
