Ihrer Meinung nach ist die Guided Biofilm Therapy die beste Zahnreinigung um eine gesunde Mundflora aufrechtzuerhalten.

Im Jahr 2007 begann sie ihre Ausbildung als Zahnmedizinische Fachangestellte (ZFA). Bereits während ihrer Ausbildung wurde ihr bewusst, dass sie in dieser Berufsspate eine höhere Qualifikation anstreben möchte. Nachdem Sie ihre Ausbildung im Jahr 2010 erfolgreich abgeschlossen hatte, absolvierte sie, neben ihrer Tätigkeit als ZFA ihre Fachhochschulreife über ein Abendgymnasium in zwei Jahren.

Im Oktober 2019 erlangte Sie nach zweijährigem dualem Studium (Dentalhygiene und Präventionsmanagement) mit sehr gutem Abschluss den akademischen Titel „Dentalhygienikerin Bachelor of Science“.

In dem Berufsbild einer ausgebildeten Prophylaxe-Fachkraft stehen nicht nur Maßnahmen zur Behandlung von Erkrankungen des Zahnhalteapparates und der Zahnhartsubstanz im Vordergrund, sondern die Aufrechterhaltung der Mundgesundheit und allgemeinen Gesundheit durch gezielte Maßnahmen in der zahnmedizinischen Prophylaxe.

All diese wichtigen Dinge vereint das Konzept der Guided Biofilm Therapy (GBT) auf höchstem Stand der Wissenschaft, mit minimalinvasiven Technologien für den größtmöglichen Behandlungskomfort für Ihre Patienten und bietet die optimale Prophylaxe mit System!

"Nel 2016 mi sono laureata presso l'Università degli Studi di Siena con tesi: “La terapia fotodinamica nel trattamento delle mucositi nei pazienti portatori di protesi totali ancorate su impianti”. Durante questi anni ho individuato i miei maggiori ambiti di interesse, focalizzando lo studio sulla terapia Parodontale non chirurgia.

Nel 2018 ho conseguito la laurea magistrale in Scienze delle Professioni Sanitarie Tecnico Assistenziali presso l'Università La Sapienza di Roma. Durante questi anni ho ampliato la mia formazione spaziando dal diritto all’economia presentando così una tesi con impronta giuridica dal titolo: “L’igienista dentale tra subordinazione e libera professione”.
Dal 2019 ho svolto il Master di I livello in Igiene Orale ad Indirizzo Parodontale Estetico ed Ortodontico in collaborazione con la Fondazione Istituto Stomatologico Toscano con tesi: “Malattia Parodontale e problematiche sistemiche: una correlazione pericolosa?”.
Nel 2020 ho intrapreso il master di Patologia Orale presso la Dental School di Torino presentando come caso clinico: “Herpes Virus: Manifestazioni Intraorale"". Ho cercato di affinare il mio bagaglio che sentivo carente su tutto ciò che interessava le patologie delle mucose gengivali non indotte da placca batterica.

Ad oggi, sono iscritta regolarmente all’Albo degli Igienisti e faccio parte del mondo EMS dal 2018."
