It is our foremost aim and duty to protect your personal data with which you entrusted us and to protect you from unauthorized access. Therefore, we are very careful and use the most modern safety standards in order to guarantee maximal protection of your personal data.

To guarantee this, we inform you of the single legal terminologies that are also used in this GDPR:

Restriction of processing

‘restriction of processing’ means the marking of stored personal data with the aim of limiting their processing in the future.

‘pseudonymization’ means the processing of personal data in such a manner that the personal data can no longer be attributed to a specific data subject without the use of additional information, provided that such additional information is kept separately and is subject to technical and organisational measures to ensure that the personal data are not attributed to an identified or identifiable natural person.

Wichtige Information zu Ihrem Besuch
Dr. Quidenus und Team mit Mundschutz bei der Behandlung.

Liebe Patientinnen, liebe Patienten.

Mein Team und ich waren und sind für Sie und Ihre Familie da. Auch während der Hochphase der Pandemie war unsere Ordination geöffnet und alle notwendige Behandlungen wurden durchgeführt. Auch heute ist der Besuch unserer Ordination absolut sicher und wichtig für Ihre Gesundheit.

Schauen Sie doch bitte, was ich Ihnen dazu persönlich zu sagen habe:
Jetzt ansehen

Sicher und geschützt behandeln

In Zeiten von Corona sind Sie bei uns genauso sicher wie zuvor und in Zukunft. Strengste Hygienemaßnahmen sind von jeher Standard in unserer Ordination, in der wir regelmäßig chirurgisch behandeln. Auch jetzt führen wir jede chirurgische und zahnmedizinische Behandlung durch. Dabei gilt maximale Sicherheit für Sie uns unser Team, so wie Sie es von uns gewohnt sind.

Wichtig für Ihre Gesundheit: Gesunde Zähne für ein starkes Immunsystem

Schieben Sie notwendige Behandlungen wie die Mundhygiene oder die Parodontitis-Therapie nicht unnötig auf. Gerade jetzt ist unser Immunsystem gefordert. Bakterielle Entzündungen im Mund belasten den Organismus und die Abwehrkräfte zusätzlich.

Ich kann Ihnen versichern, dass meine Assistentinnen und ich alles notwendige tun, um Sie und uns bestmöglich zu schützen.

Die folgenden Maßnahmen sind dabei besonders wichtig:

  1. Jeder Patient betritt die Ordination bitte nur mit Schutzmaske.
  2. An der Rezeption wird dem Patienten Händedesinfektionsmittel zur Verfügung gestellt und mit einem elektronischen Thermometer am Ohr die Temperatur gemessen.
  3. Danach wird der Patient zum WC begleitet, um sich gründlich die Hände zu waschen.
  4. Jetzt kann der Patient im Wartebereich Platz nehmen.
  5. Hier halten sich nie mehr als zwei Patienten auf – mit genügend Sicherheitsabstand.
  6. Begleitpersonen werden gebeten sich in der Zwischenzeit im schönen Börsenviertel die Beine zu vertreten.
  7. Jetzt füllt der Patient einen Fragebogen zur Covid-19 Risikoabschätzung aus und wird dann von meinen Mitarbeiterinnen in den jeweiligen Behandlungsraum begleitet.

Zur Behandlung per se:

  1. Der Notbetrieb wurde von der Regierung wieder eingestellt
  2. Alle notwendigen zahnärztlichen Leistungen bieten wir wieder an:
  3. Mein Team und ich haben uns mit spezieller Schutzausrüstung an die neue Situation angepasst. An dieser Stelle möchte ich mich bei meinen Assistentinnen bedanken, die mich mit Ihrem unfassbaren Engagement, in dieser Zeit ständig unterstützt haben.

Ich hoffe, Sie bald wieder in unserer Ordination begrüßen zu dürfen. Mein Team und ich wünschen Ihnen und Ihren Familien alles Gute:

Bleiben Sie gesund und kommen Sie gut durch diese Zeit!

Bei uns sind Sie sicher.

Ihr Dr. Andreas Quidenus und das Team aus dem Börsenviertel
