NCT05810558

Brief Summary

The purpose of this research study is to determine the impact of glycine powder air-abrasive debridement (GPAD) on the microbiology of the tissues surrounding dental implants with health and inflammation (peri-implant mucositis).

Conditions

Outcome Measures

Primary Outcomes (1)

  • gingival inflammation

    presence of redness, bleeding on gentle probing from the peri-implant sulcus

    6 months

Study Arms (2)

Arm 1 Ultrasonic

PLACEBO COMPARATOR

Subjects will receive cleaning of the peri-implant sulcus using ultrasonic instrumentation

Procedure: Ultrasonic instrumentation

Arm 2 Glycine

EXPERIMENTAL

Subjects will receive cleaning of the peri-implant sulcus using glycine powder air-powered debridement

Procedure: glycine powder air-powered debridement

Interventions

The intervention treatment consist sof glycine powder air-abrasive debridement (GPAD) using a handheld air polishing device, disposable subgingival nozzle, and glycine powder The nozzle is inserted to the depth of the pocket and all surfaces of the implant (mesial, buccal, distal, lingual) debrided for 5 seconds.

Arm 2 Glycine

The control treatment consists of supragingival and root debridement using an ultrasonic scaler on low-medium power and coronal polishing with fine grit paste

Arm 1 Ultrasonic

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age \> 18 years
  • Must have \>1 tooth-borne, non-splinted single dental implant
  • Signs of healthy dental implants (pocket probing depth \<4mm and a lack of bleeding upon probing at peri-implant site) OR
  • Signs of peri-implant mucositis (\> 4mm probing pocket depths at the dental implant site, bleeding upon probing at \>1 peri-implant site, pre-brushing plaque score of \> 1.9 (modified Plaque Index (mPI)), and radiographic evidence of bone loss less than 2mm).

You may not qualify if:

  • Uncontrolled medical condition (i.e. Diabetes, History of smoking \<5 years)
  • Pregnant or lactating females
  • Untreated periodontal conditions
  • Use of antibiotics in the past 3 months
  • Subjects treated with medication for \>2 weeks with known effects to the oral tissues (i.e. coumadin, phenytoin, nifedipine, cyclosporine, non-steroidal anti-inflammatory drugs)
  • Signs of peri-implantitis (pocket probing depth of 4-6mm with bleeding upon probing at \>1 peri-implant site AND radiographic bone loss)
  • Dental implant mobility
