Randomized and Controlled Clinical Trial to Evaluate Bacterial Adhesion on Multi-Im® Transepithelial Components

Randomized and Controlled Clinical Trial to Evaluate Bacterial Adhesion on Multi-Im® Transepithelial Components Placed on Implants

This study evaluates the efficacy of Mutli-Im® transepithelial components in the inhibition of bacterial adhesion.

The control group will be the Multi-Im® transepithelial component with the conventional surface (Multi-IM® Machined) and the experimental group will be the Multi-Im transepithelial components with the Ti-Golden® surface (Multi-Im Golden) or with the nanogolden surface (Multi-Im® nanogolden). Periodontal indices and biofilformation will be assessed during 2 months after implant loading. Metagenomic analysis and PCR technique will be implemented to assess the biofilm formation.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Multi-Im Machined	Device: Multi-Im Machined transepithelial component.; Once the implant is placed, the implant loading protocol will be decided following the clinical criteria. When implant loading is to be done, then the Multi-IM machined transepithelial component is connected to the implant.
Experimental: Multi-Im® nanogolden	Device: Multi-Im Nanogolden transepithelial component; Once the implant is placed, the implant loading protocol will be decided following the clinical criteria. When implant loading is to be done, then the Multi-IM Nanogolden transepithelial component is connected to the implant.
Experimental: Multi-Im T-Golden	Device: Multi-Im Ti-Golden transepithelial component; Once the implant is placed, the implant loading protocol will be decided following the clinical criteria. When implant loading is to be done, then the Multi-IM Ti-Golden transepithelial component is connected to the implant.
