What is the clinician's preference? [Elektronische Daten] [Frits Perdijk, Gert Meijer, Ewald Bronkhorst, Ron Koole] Introduction: The aim of this study is to inventory in the Netherlands which therapy is the clinician's first choice when restoring the edentulous mandible. Material and methods: A questionnaire was sent to all Dutch Oral and Maxillofacial surgeons. As part of this, the surgeons were invited to treat five virtual edentulous patients, differing only in mandibular residual height. Results: In cases of a sufficient residual height of 15mm, all surgeons were in favour to insert solely two implants to anchor an overdenture. In case of a residual height of 12mm, 10% of the surgeons choose for an augmentation procedure. If a patient was presented with a mandibular height of 10mm, already 40% of the OMF surgeons executed an augmentation procedure. Most (80%) surgeons prefer the (anterior) iliac crest as donor site. The choice of ‘whether or not to augment' was not influenced by the surgeon's age; however, the hospital, where he was trained, did. Surgeons trained in Groningen were more in favour of installing short implants in mandibles with reduced vertical height. Discussion: As the option overdenture supported on two interforaminal implants is reimbursed by the Dutch health assurance, this treatment modality is very popular in the Netherlands. From a point of costs and to minimize bypass comorbidity, surgeons should be more reluctant in executing augmentation procedures to restore the resorbed edentulous mandible as it is dated in literature that also in mandibles with a residual height of 10mm or less, solely placing implants, thus without an augmentation procedure in advance, is a reliable treatment option.
