Staged autogenous calvarial bone grafting and dental implants placement in the management of oligodontia: a retrospective study of 20 patients over a 12-year period

Résumé

Oligodontia demands multidisciplinary management due to its repercussions on dentofacial growth. To place implants to realize implant-borne fixed denture, preimplant surgery may be necessary if bone volumes are insufficient. Our aim was to assess bone increase following autogenic bone grafting and to discuss prosthetic options. Twenty patients followed for oligodontia, who underwent bone grafting, were treated from 2008 to 2019. Transversal and vertical bone levels were measured pre- and postoperatively to assess alveolar ridge augmentation. Mean horizontal grafting increase was 4.60 mm [standard deviation (SD) 0.79 mm], mean sinus lift increase was 9.95 mm (SD 2.35 mm). Mean implants placed per patient was 9, mean implants placed on grafted site was 5 per patient. Overall implant survival rate was 100%. All patients benefited from prosthetic procedures when it was planned to perform implant-borne fixed dentures. Within the framework of a complete treatment plan (involving paediatric dentistry, dentofacial orthopaedics, oral and maxillofacial surgery, and prosthodontics), autologous bone grafting combined or not with orthognathic surgery is fully adapted to patients with oligodontia. It allows reconstruction of favourable bone volumes for placement of implants to realize implant-borne fixed dentures, with high implant survival rates and great improvements to quality of life.
