Efficacy of a New Coating of Implantabutment Connections in Reducing Bacterial Loading: An in Vitro Study

BACKGROUND: Titanium is the gold standard for dental implants, since it has demonstrated excellent biocompatibility and osseointegration properties. The rate of osseointegration is however affected by the surface morphology and peri-implant infections may affect fixture and the long-term osseointegration outcome. Thus chemical composition of a coating at the implant-abutment junction (IAJ) surface is expected to play a key role in preventing bacterial infection. PURPOSE: model. MATERIALS AND METHODS: Twenty implants were coated in the internal chamber with PXT and twenty were used as controls. RESULTS AND CONCLUSIONS: (PG), leads to the conclusion that the coating is capable of inactivating the microbial species penetrating the internal of the implant through the implant abutment junction.
