The aim of the study was to evaluate the outcome of prosthetic treatment following treatment planning by a multidisciplinary team of specialists in young individuals with oligodontia.

Materials and methods

A multidisciplinary team comprising specialists in paediatric dentistry, orthodontics, oral and maxillofacial surgery, and prosthetic dentistry was formed in 1986 at the Institute for Postgraduate Dental Education, Jönköping, Sweden. The objective of the group was to draw up comprehensive treatment plans for children and adolescents with traumatized teeth or tooth agenesis. The overall strategy was to minimize the need for prosthetic therapy. The memorandums from the meetings of the team during the years 1986–2003 were used to identify patients with oligodontia (agenesis of six or more permanent teeth, third molars excluded). The patient records were reviewed, and the number of replaced teeth and type of treatment were recorded.


The memorandums comprised reports on 114 patients younger than 20 years with oligodontia, of which records of 100 patients were reviewed. Performed treatment comprised orthodontics/growth adapted measures, autotransplantation, replacement of missing teeth with onlay bridges, tooth-supported and implant-supported fixed partial dentures (FPDs), and removable partial dentures (RPDs). Planned treatment was carried out in 61 patients. Their total number of missing teeth was 624 (x=10.2; r=6-22), of which 260 (41.7%) teeth were replaced. Prosthetic treatment comprised 174 dental implants (r=1–11) in 40 patients, 19 onlay bridges in 12 patients, 5 FPDs in 3 patients, and 3 RPDs in 3 patients. Nine patients received only orthodontic treatment or autotransplantation and had no need for replacement of teeth. The remaining 39 patients were still growing, and the planned treatment was not finished.


In 61 young individuals with oligodontia and a total number of 624 missing teeth, only 260 teeth (41.7%) were replaced through prosthetic treatment. The most common treatment modality was dental implants. A multiprofessional team approach to treatment planning has proven valuable for the continuity and co-ordination of planning and may reduce the need for prosthetic rehabilitation.
