The aim of the present study was to follow‐up our previous prospective study that reported high implant survival in a group of Norwegian individuals with osteogenesis imperfecta. Our hypothesis was that implant treatment in these persons has approximately the same long‐term survival rate as in healthy individuals.
The previous study included seven participants (20 implants), four of them (11 implants) took part in the present study and the other three had died. The participants were followed up for an average of 93 months, subsequent to prosthetic loading. The implants were clinically and radiographically examined. Objective and subjective evaluations were recorded using an analogue scale ranging from 0 as the worst to 10 as the best score. A mean of these evaluations is presented as the subjective and objective overall satisfaction. In the previous study, no implants were lost and 1 mm bone loss was recorded around two implants. One implant was removed after 76 months due to an implant neck fracture. At the present study, four implants showed 1 mm bone loss, two of which had the same level of bone loss in the previous study. Four millimetre bone loss was observed around two other implants. No bone loss was detected around the remaining four implants. Objective and subjective evaluation of implant treatment showed an overall high satisfaction of 9.1 and 9.9 respectively.
The findings showed an implant survival rate of 91% (100%, excluding the implant neck fracture) and high recipient satisfaction towards implant treatment.
