Dental Studies Under the 2021 ZApprO – Structure, Exams and the State of Play in 2026

How is dental training structured under the 2021 ZApprO?

Dental studies in Germany comprise eleven semesters as the standard period of study under the ZApprO of 8 July 2019 and are divided into three study stages: semesters one to four, semesters five and six, and semesters seven to ten. Each stage ends with its own exam. Heidelberg University puts the total scope of training at 5,000 hours.

The shift in content is bigger than this structure suggests. Dental subject matter starts earlier, the medical subjects move closer to dentistry, and phantom-head and patient training increasingly overlap. Ludwig Maximilian University of Munich describes exactly this three-part structure as the core of the reorganisation. Heidelberg University lists the start of phantom-head work in the fourth semester and full-day courses in the fifth and sixth for its curriculum.

The scale of 5,000 hours is no coincidence. Article 34 of Directive 2005/36/EC requires basic dental training to comprise at least five years of full-time study at a university with at least 5,000 hours. Germany is thereby implementing the European minimum standard, no more and no less.

I studied dentistry in Sofia from 2015 to 2021 and remember the moment the phantom head stopped being a practice tool and became the real thing. It was not the anatomy exam that was the hurdle, but the first cavity that had to hold up under an examiner's eye. Anyone comparing degree programmes today should therefore look less at the number of semesters and more at when the hands start working.

What do Z1, Z2 and Z3 examine, and when do they take place?

Z1, Z2 and Z3 are the three stages of the state dental examination under the ZApprO. Z1 is an oral exam that takes place at the earliest at the end of the fourth subject-semester. Z2 follows at the earliest two subject-semesters later and is taken orally and practically on the phantom head. Z3 is the final state examination, made up of a nationally standardised written part and an oral-practical part.

• Z1 examines the natural-science and medical fundamentals and is taken during the lecture-free period.
• Z2 covers prosthodontics, orthodontics, oral surgery, and restorative dentistry including endodontics, paediatric dentistry, periodontology and dental hard-tissue science.
• Z3 covers fourteen medically oriented subjects in its written part; the nationally standardised dates fall in June and November.

Dates are organised by the individual federal states. In Saxony, Z1 dates in 2026 ran from 2 to 27 March and from 31 August to 25 September, with application deadlines of 10 January and 10 June at the state examination office. How much the exams tie up faculties is shown by a figure from the German Medical Faculty Association's position paper of 17 August 2017: the length of the oral-practical exam rose from a previous 30 to 45 minutes to a minimum of 45 and a maximum of 60 minutes per candidate.

What practical placements does the ZApprO require alongside coursework?

The ZApprO requires three practical placements that are easy to overlook in everyday study life. Before admission to Z1, evidence of first-aid training and one month of nursing placement work must be provided. After Z1 and before Z3, a four-week internship in a dental practice is added. On top of that comes the elective-subject system.

An optional elective can be taken up to the first exam, and a compulsory elective must be completed by the third stage. It sounds like a side issue. It is not: anyone who leaves the nursing placement and internship too late quickly loses an entire semester in the tightly scheduled curriculum, because admission to the next exam depends on this evidence.

Does the pre-clinical qualifying exam in dental studies still exist?

Not for students under the 2021 ZApprO. The natural-science and dental pre-qualifying exams belong to the old system that applied before 1 October 2021; Z1 and Z2 have taken their place. Many advice websites and some faculty pages still reflect the old status to this day.

The old regulations remain practically relevant only for students who started before the change, and the transition periods are tight. Saxony's state examination office notes that students not yet admitted to the second stage continue under the new curriculum until 30 March 2028 and no longer sit the Z2. Anyone researching this should therefore always check the date of the source.

What did the amending regulation of 25 November 2024 change?

The amending regulation to the ZApprO was published on 25 November 2024 in the Federal Law Gazette and has applied to exams since 2025. It allows electronic applications, clarifies the scope and duration of the Z1 to Z3 exams, organises the subject groupings more clearly, and eases transitional cases. It was prepared by Bundesrat document 438/24 of 5 September 2024.

This document is the most revealing source on the topic, and it is otherwise rarely cited. It states the reduction in burden concretely: for citizens, specifically for dental students, a reduction of 10,917 hours; no additional burden for business; for the federal states, an annual reduction of EUR 19,280 thousand against a one-off additional burden of EUR 529 thousand. Since then, Section 19(3) has stated that applications for admission may be submitted in writing or electronically.

A calculation of my own to make the number of hours tangible: setting the 10,917 hours against the 2,246 newly enrolled students of 2024 from the KZBV Yearbook 2025 works out at roughly 4.9 hours per student in a cohort. The comparison is deliberately imprecise, because the regulator adds up all affected cohorts rather than a single one. It nonetheless shows the order of magnitude: this is an afternoon of paperwork per person, not a structural relief.

The Association of University Teachers of Dentistry, Oral and Maxillofacial Medicine, the German Medical Faculty Association and the German Dental Association had campaigned since 2022 for workable exam conditions. The proposed change in wording from “Praktikum” (placement) to “Kurs” (course) was not adopted by the Bundesrat.

How many places are there in dental studies, and why do the figures not match?

Two figures circulate side by side. The KZBV Yearbook 2025 lists 2,246 newly enrolled dental students nationwide for 2024. The Foundation for University Admissions, by contrast, lists 1,526 new entrants for the winter semester 2024/25 against 10,954 applications. Both figures are correct, because they count different things.

The explanation: the Foundation for University Admissions records only the places it allocates itself in a single winter semester through the central procedure. The KZBV Yearbook counts new enrolments across a whole year and across all entry routes. Anyone unaware of this difference can read either a dramatic or a relaxed picture from the same statistics. This is my own interpretation of the two sources, not an official statement.

What is clear is how tight the central procedure is: around seven applications came in for every place allocated for the winter semester 2024/25. The number of licences issued stood at 2,448 in 2024, and the Federal Statistical Office recorded, according to the German Dental Association, 1,801 passed state exams, 1,210 by women and 591 by men, at an average age of 26.97.

The capacity question has accompanied the reform from the start. The German Medical Faculty Association noted on 17 August 2017 that the assumed cost-neutrality of the regulation rested, arithmetically, on a six percent reduction in dental study places, and described that assumption as unconvincing. In its position paper “Dental Studies of the Future” of May 2021, it pointed out that the curricular standard value had been lowered from a planned 9.67 to 8.86. No drop in entrant numbers is visible in the nationwide data up to 2024. Whether that is down to adequate funding or reallocation within faculties remains open; reliable data on this is lacking.

What does dental training look like in Hungary, Bulgaria, Croatia and Romania?

Basic dental training is harmonised across the EU by Article 34 of Directive 2005/36/EC: at least five years of full-time study at a university. Article 35 governs specialist dental training. Anyone holding a qualification listed under item 5.3.2 of Annex V is entitled to automatic recognition in all member states, including Germany.

Two things stand out in this comparison. Study length is not the same everywhere: Hungary runs dentistry over five years, Croatia and Romania over six, and Bulgaria over five years plus a subsequent six-month internship. And the programmes are internationally oriented: Semmelweis University teaches dentistry in Hungarian, English and German, while Cluj-Napoca has advertised 100 places on its English-language and 75 on its French-language programme for 2026/27.

One limitation is worth stating plainly: several universities do not publish their fees at all, and the Pécs figure dates from the 2022/23 academic year. A clean price comparison across all locations is not currently possible from public sources. Which location fits which profile is therefore something we prefer to look at together: book a free consultation.

What do these figures mean for starting out as a dentist?

According to German Dental Association statistics, 103,998 dentists belonged to the chambers in Germany in 2024, of whom 73,511 were practising: 43,663 in their own practice, 29,848 employed. The number of panel dentists fell from 45,676 in 1992 to 43,166 at the end of 2024, and to 42,548 in the first half of 2025.

Care density remained high. The KZBV Yearbook 2025 lists 1,137 residents per practising dentist for 2024, compared with 1,496 in 1991 in the former West German states. What has shifted above all is the timing of setting up in practice. A study by the German Institute of Dentists, reported on by zm in 2026, puts the average age of establishing a practice at 36.3, with an average of 8.7 years between licensing and setting up in practice and 12.6 months between the decision and its implementation. Around 90 percent of respondents chose self-employment out of conviction.

There is therefore a long period of employment today between finishing exams and running your own practice. I know this transition from my own experience, and it feels different from what you expect during your studies. In the exam, what is assessed is what you know. In practice, what counts is how fast you decide when a patient is sitting in the chair in pain and the findings do not match the textbook. That adjustment takes months, not days. This is exactly what the ZApprO is aiming for with its earlier focus on practical work, which is why I consider the direction of the reform to be right.
