The purpose of this study was to investigate the biomechanical causes of hydroxyapatite (HA) coated blade implant fracture. The results of three-dimensional Finite Element Analysis (3 D-FEA) indicated that the cause of these fractures was the connection of osseointegrated implant and tooth with a poor periodontal condition.
