Gunter Flatischler

Introduction

Günter Karl Rudolf Flatischler is a former UK dentist — qualified as a tandläkare at Sweden’s Karolinska Institutet in 1996 and registered with the General Dental Council (GDC) under number 72439 — whose registration was ended in December 2025, when the GDC’s Professional Conduct Committee found his fitness to practise impaired by reason of misconduct and directed erasure. The case concerned his orthodontic treatment of two child patients and his failure to cooperate with the regulator’s investigation. He did not attend the 1–4 December 2025 video-link hearing, and the committee proceeded in his absence.

Background Information

At the relevant times Flatischler practised at a dental practice — not named in the published determination — where he provided orthodontic treatment to two children: Patient 1, then 12, and Patient 3, then 11, whose treatment began in August 2019. Patient 1’s mother complained to the GDC in May 2021; Patient 3’s mother complained in October 2021, after a final appointment on 30 October 2021 at which she learned that Flatischler was closing the practice and returning to Austria the following day. An investigation begun on 14 August 2021 produced repeated requests for his patient records and his employment and indemnity information, none of which was ever provided. His only substantive contacts were an email enquiring about voluntary removal from the register and a voicemail on 1 October 2025.

The Controversy or Incident That Led to Their Cancellation

Adjudicated vs. alleged. The findings against Günter Karl Rudolf Flatischler were made by the GDC’s Professional Conduct Committee on the balance of probabilities, at a hearing he chose not to attend. They are regulator findings, not criminal convictions; no criminal allegation is recorded on this page.

The committee heard evidence from both mothers and from the GDC’s expert, Professor Nigel Hunt of UCL Eastman Dental Institute, and found every head of charge proved. For Patient 1, it found that between October 2020 and late 2021 she was not seen regularly — a gap of almost a year, during which her mother telephoned the practice around twenty times and attended in person on four occasions, each time finding it locked; that between March and May 2021 he did not respond to her concerns in a timely manner; and that after removing Patient 1’s braces in late 2021 he did not arrange supervision of the retentive period. Head of charge 1(c) was amended under Rule 18 to add “and/or arrange for supervision of the retentive period”, because messages between the mothers suggested a retainer had in fact been posted to Patient 1 — it was more likely than not provided — but it proved the charge on the supervision failure. Professor Hunt’s evidence was that supervision is required for up to a year after brace removal and that not supervising the retentive period is “a failure of basic skills” that could result in relapse.

For Patient 3, the committee found he did not carry out sufficient treatment planning for the boy’s unerupted second molars — x-rays later taken by his subsequent orthodontist showed both lower second molars impacted — and provided a poor standard of treatment by never fitting the twin block appliance in his own treatment plan, using elastic bands instead. Professor Hunt’s accepted opinion was that the treatment actually supplied “was incapable of achieving the treatment objectives and the patient’s dentition has been left in a potential harmful and unsatisfactory state”. It also found proved that he failed to advise Patient 3 in a timely manner that he could not complete treatment and that the practice was closing: the mother learned of it at the last appointment, only because she asked, and was told “I won’t forget you”. Patient 3 has since had five teeth removed. Finally, the non-cooperation charges were proved: from August 2021 onwards, Flatischler gave the GDC neither access to patient records nor employment or indemnity information.

Public Reaction and Consequences

No public or media reaction to the case is recorded in the determination, so the consequences that matter are the committee’s. At the second stage it found the proved facts amounted to misconduct and current impairment. Its findings record that Flatischler “placed Patient 1 at risk of harm and caused actual harm to Patient 3”, that his risk of repetition was high, and that members of the public “would be shocked” if no impairment finding were made in a case involving two vulnerable child patients. The aggravating factors it listed included actual harm or risk of harm, premeditated misconduct in the manner in which he told Patient 3 of the closure, and financial gain — Patient 3’s mother had paid in advance for treatment never completed. The only mitigation was previous good character. The GDC submitted that a 12-month suspension with review would suffice, but the committee went further: his behaviour, including the lack of any insight and his continued non-engagement, was “fundamentally incompatible with being a dental professional”, showing “complete disregard for the patients in this case, for his regulatory body and for the public’s perception of the dental profession”. It directed erasure and imposed an immediate order of suspension on 4 December 2025.

Current Status

Flatischler is struck off the GDC register. The regulator record carries a decision date of 5 December 2025 and the outcome erasure; unless he appeals, his name will be erased from the Dentists Register 28 days from deemed service of the determination. The immediate suspension order covers the appeal period and remains in force should he appeal, so he may not practise as a dentist in the United Kingdom in the interim either way. No appeal is recorded in the published record.

Impact on Their Career/Life

The erasure direction ends Flatischler’s ability to practise dentistry in the United Kingdom. It is the regulator’s highest sanction, imposed on a finding of high risk of repetition with no evidence of insight or remediation, and any restoration would have to be sought through the GDC’s processes. The determination also fixed the character of the case: not one clinical error but a pattern — nearly a year without review for a child in braces, no supervision after brace removal, a treatment plan abandoned without telling the family, four years of ignoring the regulator. His non-cooperation shaped the case itself: no patient records were ever provided, so the committee decided it on the mothers’ evidence and Professor Hunt’s, and the withholding of records was a proved charge in its own right. The record is otherwise silent about his life beyond the register.
