Investigation of Biofilm Formation on Temporary push-on Rings of Implant Crowns

Temporary push-on Rings of Antimicrobial Alloys for Transmucosal Implant Abutment Systems: a Randomized Clinical Study on Early and Mature Biofilm Formation

Sponsor

University Hospital, Basel, Switzerland

Enrollment

33 participants

Start Date

Jan 11, 2022

Study Type

INTERVENTIONAL

Conditions

Peri-implantitis Oral Biofilm Dental Plaque

Summary

This in-vivo study investigates early (48h), mature (2 weeks) and long-term (3 months) biofilm formation and composition on temporary push-on cones (exchangeable conical rings) made of noble-alloy-based materials (Pagalinor, PA) in comparison to Titanium-6Aluminum-7Niobium alloy (TAN) presently used in the transmucosal portion of dental implant abutments.

Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This clinical trial is studying a medical device called Rings made of PA (test) and a medical device called Rings made of TAN (control) for people with dental plaque, oral biofilm, and other related conditions. The study is currently recruiting participants at 1 location. People eligible for this study include aged 18 Years and older.

This summary was AI-generated to explain the trial in plain language. It is not medical advice. Always discuss eligibility with your doctor before enrolling in a clinical trial.

Interventions

DEVICERings made of PA (test)

Rings made of PA (test) 0.2mm in thickness are pushed on the conical titanium base (abutment) of implant crowns and are removed and replaced after 48h, 2 weeks and 3 months for quantification of the bacterial biofilm. Test rings are applied in a split-mouth design provided that 2 implants are present (total of 4 months study period), or one after the other when only 1 implant is present (total of 8 months study period).

DEVICERings made of TAN (control)

Rings made of TAN (control) 0.2mm in thickness are pushed on the conical titanium base (abutment) of implant crowns and are removed and replaced after 48h, 2 weeks and 3 months for quantification of the bacterial biofilm. Control rings are applied in a split-mouth design provided that 2 implants are present (total of 4 months study period), or one after the other when only 1 implant is present (total of 8 months study period).
