Brief Summary

Erythritol is a natural sugar alcohol (a four-carbon polyol) produced by the reduction of erythrose. It is considered safe as food additive and has many of the functional properties that are important for subgingival debridement. Current evidence includes no prospective studies comparing the outcomes of a low abrasive erythritol air-polishing as an adjunctive therapy to conventional titanium and ultrasonic debridement of patients in a maintenance program with peri-implantitis. Thus, the main purpose of this randomized, single-masked controlled trial (RCT) is to assess whether low abrasive erythritol air-polishing has an adjunct effect to conventional non-surgical treatment of peri-implantitis.

Outcome Measures

Primary Outcomes (2)

  • Changes in probing depth (PD)

    PD as the distance in mm from the implant mucosal margin to the probable base of the pocket at six sites;

    12 moths

  • Crestal bone level (CBL)

    Intraoral digitalized radiographs will be taken with customized Eggen-holder and long cone, parallel technique to assess CBL. The distance from implant platform to the mesial and distal bone levels will be measured by using the software program DIGORA (Soredex, Helsinki).

    12 months

Secondary Outcomes (3)

  • Bleeding on probing (BoP)

    12 months

  • Gingival crevicular fluid (GCF)

    12 months

  • Visual analogue scale (VAS)

    12 months

Study Arms (2)

Titanium curette and ultrasonic.

ACTIVE COMPARATOR

You may not qualify if:

  • Surgical treatment of peri-implantitis the last 6 months
  • Supportive periodontal therapy within 3 months
  • Use of systemic antibiotic within 6 months
  • A history of non-compliant behavior
  • Inflammation around implant without evidence of bone loss
  • Periapical peri-implantitis
  • Subjects with implant fracture, ceramic implants, or detectable subgingival cement

Masking Details
Forty patients diagnosed with peri-implantitis on at least one implant will be randomly allocated by tossing a coin into test or control group. Two different operators will participate in the study (ML and AS). ML masked to the treatment assignment, will collect the data, and AS will perform the treatment.
