Mi nombre es Erik Regidor y soy licenciado en Odontología y especialista en Periodoncia e Implantes por la Universidad del País Vasco. Desde entonces me dedico en exclusiva a Periodoncia e Implantes en PerioCentrum Bilbao. Adicionalmente participo en proyectos de investigación relacionados con mi campo dado que formo parte de los grupos de investigación Arrow Development y ThinkingPerio Research. Fruto de ello estoy actualmente realizando mi doctorado enfocado en el tratamiento quirúrgico de la peri-implantitis. Esto me ha llevado a participar en publicaciones científicas a nivel nacional e internacional dándome la oportunidad desde hace unos años a impartir cursos de formación. Entre otros, soy Trainer de EMS desde el año 2020 y tengo el honor de participar en proyectos de formación tanto para odontólogos como para higienistas.

Nach meinem Abschluss zur Zahnarzthelferin 1998 habe ich mich für den Bereich Prophylaxe entschieden. Selbstständiges Arbeiten macht mir Spaß, und so ging mein Weg über ZMP zur DH weiter. Als ich die Leitung einer Prophylaxe Abteilung übernahm, machte ich noch eine Weiterbildung zur Prophylaxe Managerin der IHK. Um meine Patienten intensiver unterstützen zu können, entschied ich mich noch die Weiterbildung zur dentalen Ernährungsberaterin zu absolvieren. Neben meiner Tätigkeit als GBT Trainerin der SDA bin ich in Teilzeit in München als DH angestellt. Somit dreht sich mein berufliches Leben um Zähne und GBT. Ich bin ein großer GBT Fan, weil es ein Benefit für Patient und Behandler ist. Und wenn ich nicht mit der Zahngesundheit beschäftigt bin, dann sitze ich auf dem Fahrrad und genieße die Natur. 

Higienista dental y protésica. Actualmente practica privada y gerente de Vemar Dental. Ponente MBA dental.

Soy odontóloga generalista y he trabajado en el campo dental desde el 2012 desempeñando roles que cubren toda la cadena de valor del servicio de salud dental: desde asistente en sillón, pasando por auxiliar en gabinete, atención al paciente, agente comercial, higienista y finalmente como dentista. Todo esto me ha permitido estar al día con los avances científicos y tecnológicos, a la vez que me ha dotado de una perspectiva global del funcionamiento de las clínicas dentales, lo que aporta dinamismo, profesionalidad y eficacia a mi trabajo.

Persigo el ideal de ejercer una odontología de alta calidad, y además, tengo profunda vocación para la enseñanza, por lo que me encantaría que ese ámbito formara parte del día a día en mi práctica profesional. Soy una apasionada de la periodoncia y la estética dental, y tengo muchas ganas de aprender y crecer.

Ihrer Meinung nach ist die Guided Biofilm Therapy die beste Zahnreinigung um eine gesunde Mundflora aufrechtzuerhalten.
Ihr Statement ist, dass eine gute Parodontologie bedeutet den Dentalhygienikerinnen genügend Zeit zu geben. Auch in den Trainings geht Sie sehr darauf ein. Vorbeugen ist besser als Heilen! Zudem ist Vanessa Yogalehrerin und bildet sich zur Zeit in Ayurvedischer Medizin fort.
