Primary failure of eruption ( PFE ) is a sporadic or inherited disorder of dental eruption that can be caused by mutations in the PTH 1R gene. PFE typically manifests as a severe posterior open bite. Orthodontic treatment is considered ineffective in PFE . Case presentation Here, we report two unrelated PTH 1R ‐negative cases of severe eruption disorders presenting several of the typical clinical features of PFE , and where we tracted the impacted teeth using Bollard bone anchors. Management We managed to obtain a satisfactory occlusion in both cases without extended ankylosis induced by the orthodontic movements based on bone anchors. Outcome These cases underline the need for a better understanding of the genetics of dental eruption disorders related to PFE before establishing strict clinical guidelines ruling out potentially efficient orthodontic management protocols within the PFE spectrum.
