Children and adolescents with oligodontia – a 10 year evaluation of a multidisciplinary approach to oral habilitation

Norderyd J*, Bergendal B, Olson L


Multiple tooth agenesis, oligodontia, is a rare condition and can be considered an oral disability. When planning oral habilitation in a growing child, attention has to be paid to dental status as well to the child's physical and psychological development. With the objective of minimising the future need for prosthetic treatment, a multidisciplinary group of specialists at the Institute for Postgraduate Dental Education in Jönköping, Sweden, have met regularly in order to plan treatment for children with hypodontia.


The aim of this study was to analyse the diagnoses of the children with oligodontia and the choice of treatment options presented by the multi-disciplinary group.

Materials and methods

This is a retrospective study of the records of the 90 patients with 6 or more con-genitally missing teeth that have been subjects of multi-disciplinary treatment planning by a group of specialists in orthodontics, paediatric dentistry, oral and maxillo-facial surgery, and prosthodontics between 1990 and 1999.


26 of the children had, in addition to oligodontia, a medical and/or a psychiatric diagnosis. Among these diagnoses, ectodermal dysplasia was the most frequent. The treatment strategies discussed included supervised occlusal development, guide extractions of primary teeth, orthodontic treatment, autotransplantation of permanent teeth, removable partial dentures, tooth- and implantsupported fixed partial dentures, and orthognathic surgery.


  • One-third of the children had oligodontia combined with a syndrome or medical diagnosis.
  • A multidisciplinary approach is beneficial for an optimal treatment outcome.
  • Early treatment planning is favourable for strategic decisions on therapy.
