The European Board of Aligner Orthodontics established two membership categories, achievable after passing the qualification exam:

Certification as Clinical Master member of the European Board of Aligner Orthodontics is conferred after display of the required number of treated clinical cases demonstrating the high standard demanded.

Certification as Honorary member of the European Board of Aligner Orthodontics is conferred, in exceptional circumstances, to those who distinguished themselves providing a clinical and/or scientific contribution to the establishment, ideas, purpose or persistency of the European Board of Aligner Orthodontics.

The pathways to successful Board Certification are summarized in the figure below:




Terms and conditions related to the successful exe- cution of the EBAO certification examination process comprise:

  • English is the only language allowed for the EBAO certification process; the candidate has the right to use an interpreter at his/her expense.

T1 records are mandatory.

Follow-up (T2 records after at least 24 months would be appreciated)

Stage 1
Two (2) cases shall be presented as requested by EBAO Scientific Committee. These 2 cases must fall into the types of cases listed in 2.4

Stage 2
A further there (3) cases shall be presented as requested by EBAO Scientific Committee. These 3 cases must fall into the types of cases listed in 2.4 but should not be of a similar type as presented in Stage 1.

The case display EBAO membership shall include 5 cases chosen among the listed categories (only one case per category):

1) Early treatment in a Growing Patient
Treatment must be started in primary or mixed dentition. A completed Phase I treatment could be eligible.
The treatment could be carried out in one or more phases: if the treatment consists of more than one phase, interim records are required following the competition of the various stages.

2) Adult malocclusion
Treatment must be started in permanent dentition when craniofacial growth is already finished. Interdisciplinary cooperation is hereby accepted.

3) Class I malocclusion
Class I malocclusions have mostly normal anteroposterior tooth relations combined with a discrepancy between tooth size and dental arch length. The discrepancy is usually crowding and less often excessive spacing between the teeth. Patients with Class I crowded malocclusions have larger than normal teeth, smaller than normal arch lengths, and smaller than normal arch widths. Overbite and overjet vary in Class I malocclusions. Anterior and posterior crossbites appear in this type of malocclusion as well as eruption problems.

4) Class II division I malocclusion
In Class II/1 malocclusions, the lower teeth are distal to the upper teeth, usually resulting in larger than normal overjet. The upper incisors often have increased labial inclination, making the incisor crowns susceptible to accidental fractures. The distobuccal cusp of the upper first molar occludes with the buccal groove of the lower first molar. The maxillary canine crown tip is located near the mesial surface of the mandibular canine. Patients with these malocclusions may or may not have crowded arches and vary in the degree of overbite from open bite to deep overbite. On average, maxillary arch widths are narrower in Class II/1 patients than in persons with normal occlusion. Also, end to end molar and canine occlusions are included.

5) Class II division II malocclusion
In Class II/2 malocclusions, the upper incisor crowns, especially those of the upper central incisors, are inclined to the lingual, in contrast to the excessive labial inclination observed in many Class II/1 malocclusions. The number of maxillary incisors with lingual inclination varies from one to four. The lingual inclination of the upper central incisors results in small to moderate overjet measurements. Overbite is often deeper than normal because of the lingual inclination of the upper incisors. The collum angle between the long axis of the crown and the long axis of the root in maxillary central incisors has been shown to be larger in a sample of Class II/2 patients compared with other occlusion groups. Class II/2 patients with large collum angles are predisposed to larger than nor mal overbites. The maxillary arches of patients with this malocclusion are narrower than normal but significantly larger than the widths observed in Class II/1 patients. Few of these patients have posterior crossbites. Also, end to end molar and canine occlusions are included.

6) Class III malocclusion or Class III tendency
In this class of malocclusion, the lower teeth are mesial to the upper teeth, usually resulting in anterior crossbite. The mesiobuccal cusp of the upper first molar occludes with the embrasure between the lower first and second molars. Overbite varies from open bite to deep overbite. The alignment of the teeth in the arch varies from good to severe crowding, with the upper arch being more prone to crowding than the lower arch. On average, the maxillary arch widths of these patients are narrower than those in normal occlusions. The narrowness of the upper arch and the anteroposterior displacement of the arches are often associated with posterior crossbites.

7) Transversal Discrepancy
Includes posterior crossbite malocclusion (full or partial) and scissor bite malocclusion (full or partial). In posterior crossbite malocclusions, the buccal surfaces of lower teeth project farther buccally than the buccal surfaces of the upper posterior teeth. Scissors bite is the term used to describe the condition when the upper molars are positioned outward, or the lower molars are positioned inward so that the molars miss each other and overlap when the mouth is closed.

8) Vertical Discrepancy
Includes anterior or posterior openbite or deep bite. Anterior open bite (AOB) represents a failure of vertical overlap between maxillary and mandibular incisors. Posterior open bite (POB) occurs when the teeth are in occlusion there is a space between the posterior teeth. Cross bite exists where a tooth (or teeth) has a more buccal or lingual position (that is, the tooth is either closer to the cheek or the tongue) than its corresponding antagonist tooth in the upper or lower dental arch.

Each of the presented cases will be evaluated by the Scientific Committee, which will be unknown until the day of examination. Each case may be evaluated as follow:

“Case approved”: it meets all the excellence standards requirements for EBAO membership.

“Case accepted”: it meets the standards requirements for EBAO membership partially, so it needs to be revised or replaced.

“Case to be revised / replaced”: the case only partially meets the standards requirements for EBAO membership, so the case needs to be amended or replaced.

If the candidate collects two (2) approvals by the scientific committee, he/she will be awarded the Proficiency Award.

If the candidate collects a further 3 (3) approvals by the scientific committee, in combination with the two (2) stage 1 approved cases, he/she can move forward to the oral presentation.
If the oral presentation is deemed successful, he/she will be awarded the EBAO Certification of Clinical Excellence.

If one (1) or more cases will be revised or replaced, the candidate has the possibility for the following twentyfour (24) months to take part in case presentation.

Minimum records to be included in case presentations are the following:

T0 records (before any active treatment, including extractions) = “black” label

  • Dental models (digital model)
  • Orthopantomogram
  • Lateral radiograph of the skull
  • Cephalometric assessment of lateral radiograph of the skull
  • Extra-oral Photographs
  • Intra-oral Photographs

T1 records (at the conclusion of major active treatment) = “red” label

  • Dental models (digital model)
  • Orthopantomogram
  • Lateral radiograph of the skull (can be made prior to the suspension of treatment or prior to any refinement)
  • Cephalometric assessment of lateral radiograph of the skull (can be taken prior to the cessation of treatment or prior to any refinement) with T0 superimposition
  • Extra-oral Photographs
  • Intra-oral Photographs

T2 records (retention records, after at least 24 months after the conclusion of treatment) = ”green” label

  • Dental models (digital model)
  • Orthopantomogram (optional but appreciated)
  • Lateral radiograph of the skull (optional but appreciated)
  • Cephalometric assessment of lateral radiograph of the skull with T2 superimposition (optional but
  • Extra-oral Photographs
  • Intra-oral Photographs

Please note that the T2 set of records is mandatory only for two (2) out of five (5) presented cases.

Please also note that all digital images presented by candidates must be original high quality images with no alterations except peripheral cropping. Presentation of pictures with unauthorized modification (including but not limited to “instant alpha” or similar, background elimination, or like manipulations) will result in automatic disqualification of the candidate and forfeiture of the examination fee.

Please also note that the radiographic records at least two years after active treatment are optional because they present no benefit to patients to justify their execution. In recognition of good radiation hygiene practices (ALARA principle), the Scientific Committee emphasizes that it does not wish to imply that radiographs should be taken solely to satisfy case requirements for presentation. All the radiographic records should be accurately standardized, oriented and processed and could be presented in digital form; the original x-ray could be requested if it is necessary. The essential anatomical structures should be easily identified through the radiographic records; The soft tissue profile should be visible on lateral cephalograms.

The cephalometric tracing should face to the patient right. Computer tracings with complete anatomical lines constructed are preferable, but also drawn by hand tracing is well accepted. Every cephalometric tracing must have the proper color depending on the treatment phase (pretreatment black, treatment progress blue, pos or near the end of treatment red, retention or post retention green).

To assist with cephalometric analysis and the recording of the cephalometric readings required by EBAO examination, EAS has come to an agreement with Major Partners, which allows EBAO applicants to purchase a demo licence for those who are interested in using Dolphin Imaging to prepare their cases for the EBAO Examination.

The EBAO Oral examination aims to demonstrate critical thinking, clinical decision-making-ability, competence in the field of orthodontics with special regards in aligner orthodontics.

The oral examination consists of about 30 min debating one of the presented cases (if the oral exam follows the case presentation).

EAS has established the Robert Boyd Award in acknowledgement of the huge contribution Dr Robert Boyd has made to the inception of orthodontic aligner therapy.
The Boyd Award will be awarded every 2 years, during the year of EAS Congress.

The Award is open to candidates who are:

  • an orthodontist (or post-graduate orthodontist)
  • full- or part-time teachers of orthodontics in a graduate program or be a department chair in an orthodontic program
  • persons associated with orthodontic research, such as that of a primary investigator or a member of agroup research program
  • persons who have published his/her work
  • persons making an essay-presentations at the constituent or national aligner societies level will beviewed more favourably
  • the nominee must be living at the time of the nomination
  • the nominee must belong to a National Orthodontic Society.

In addition to the Award, it will be included a monetary award of Euro 2,000 (two thousand Euro). Candidates are expected to provide a curriculum vitae/resume, which outlines such areas as orthodontic teaching/research accomplishments, orthodontic teaching/research positions held, orthodontic publications,and orthodontic scientific presentations, with each nomination.

The Robert Boyd Award recipient may be a citizen of any country, and in years divisible by three (e.g. 2001) nominations must be citizens of countries other than Europe.
