To become an active member of W.S.L.O. the candidate must present the documentation of minimum 3 clinical cases treated by the lingual orthodontic appliance. All cases should be treated using the lingual multibracket appliance on both arches. The clinical documentation must strictly correspond to the rules imposed, which are explained in detail further on. The case is evaluated entirely upon the results of treatment. No evaluation is made upon the kind of lingual appliances or auxiliaries used during treatment. Patient appearance and smile should improve after treatments and emphasis is placed upon the over-correction of dental facial abnormalities. Application to become an active member is limited to those who have a degree in medicine or dental surgery and who have legal rights to practice orthodontics according to laws and regulations of their country. Candidates must hold a degree in Medicine or dentistry for at least 5 years. Examining Model Display Commission will be composed by active or founder members of W.S.L.O. selected by the Scientific Committee. Candidates must declare that the cases presented have been treated exclusively by the candidate and declare that any decisions of the Model Display Scientific Committee will be accepted as final. At the discretion of the Model Display Scientific Committee the candidate may be requested an oral explanation of the cases presented. The official language is English. At least one of the cases presented the treatment must involve extractions. Each of the cases requires the following records in English. 1. (a) A diagnostic description of the malocclusion and the functional status (b) Treatment plan including the reasons for it (c) A resume of the actual treatment carried out including any difficulties encountered 2. Dental casts taken immediately before treatment and post treatment. An initial lateral skull radiograph with the teeth in habitual occlusion is mandatory. 3. 4. Such other skull radiographs as may be necessary for subsequent monitoring. 5. Tracings of the lateral skull radiograph (S) traced according to the candidate’s usual practice. 6. Periapical or panoramic radiographs of adequate diagnostic quality before and towards the end of treatment. 7. Orientated full face, profile and intra-oral color photographs (at least 5 x 8 cms) taken before, after treatment (optional: one year after the completion of treatment). 8. At least two intermediate treatment steps must be shown in both arches in all cases presented. 9. Any additional patient records as may seem desirable. When the candidate applies for the examination they are sent forms on which to present their records as this helps the examination process. Each of the presented cases is evaluated by the examiners using the evaluation form.
The result of the examination could be “pass”, “incomplete” or “deferred”. If a candidate presents cases which are not complete in the required records they are told that the records are incomplete and none of the cases are examined. When a candidate is deferred the Model Display Scientific Committee will advise the candidate on re-examination.
INSTRUCTIONS TO CANDIDATES
In order to examine a large number of cases fairly and accurately, it is important that case presentations are standardised as this helps the work of the Model Display Scientific Committee members. Candidates must limit written summaries, in English, to the space provided. The size of the type can be changed, but the spacing should remain constant. Each page should be placed in transparent protective cover and the pages placed in a suitable binder or file. Tracings should be made in the prescribed colors – black, red and green, on transparent material and placed inside the protective covers. White background paper should not be included as the tracings will be removed for checking and comparison. Superimposition should not be written by using computer. Each of the cases presented should have the following details, which, unless otherwise stated, are mandatory, on each of the succeeding pages. Each candidate will be judged by a number and not by his name: the number will be assigned to the candidate by the Secretary at t the moment of the candidate’s inscription to assure anonymities and in order to avoid any influence on the Model Display Scientific Committee decision.
