Abstract
The aim was to present the successful esthetical and functional rehabilitation of partial anodontia
in a case of severe ectodermal dysplasia with complete atrophy of the jaws. A 17‑year‑old
male with Class III malocclusion with partial anodontia sought dental implant treatment.
His expectation was that of Class I occlusion. The challenge in the case was to match the
expectation, reality, and the clinical possibilities. Ridge augmentation was performed with a
combination of rib graft and recombinant human bone morphogenetic protein‑2. Simultaneously,
6 implants (Nobel Biocare™ ‑ Tapered Groovy) were placed in maxillary arch and 10 in the
mandible. Simultaneous placement ensured faster and better osseointegration though a mild
compromise of the primary stability was observed initially. After adequate healing, Customized
Zirconia Procera™ system was used to build the framework. Zirconia crown was cemented
to the framework. Radiological and clinical evidence of osseointegration was observed in
all 16 dental implants. Successful conversion of Class III to Class I occlusion was achieved
with the combination of preprosthetic alveolar ridge augmentation, Procera™ Implant Bridge
system. Abnormal angulations and or placement of dental implants would result in failure of
the implant. Hence conversion of Class III to Class I occlusion needs complete and complex
treatment planning so that the entire masticatory apparatus is sufficiently remodeled. Planning
should consider the resultant vectors that would otherwise result in failure of framework or
compromise the secondary stability of the dental implant during function. A successful case
of rehabilitation of complex partial anodontia is presented.
