“…The MnP2 shows great variation in its developmental pattern [6] The degree of root development is an important consideration when choosing a treatment strategy [1,8]. An immature root is beneficial for spontaneous eruption.…”

“…To correct the position of an ectopically located tooth germ, intentional extraction of primary predecessors, surgical exposure, and surgical repositioning are considered [1]. Many case reports have described the spontaneous eruption of an ectopically located permanent teeth following a combination of simple extraction of the primary predecessor and subsequent use of space maintainers [1,7,8]. However, Fux-noy [9] reported that the premature loss of mandibular primary second molar could lead to distal migration and ectopic eruption of the first premolar despite placement of a space maintainer.…”

Distal displacement of the tooth germ of the mandibular second premolar (MnP2) leads to its impaction and obturation of the eruption path of the mandibular first molar delaying its eruption. The present case report describes the treatment of 2 cases of eruption guidance for distally displaced developing MnP2 that caused delayed eruption of the mandibular first molar. Intentional extraction of primary predecessor results in the mesial shift of the displaced MnP2. However, unfavorable distal ectopic eruption of the mandibular first premolar after the premature loss of primary second molar has been previously reported. Hemisection and sequential extraction of the mandibular primary second molar were performed to mesially shift the distally displaced MnP2, while preventing unfavorable distal ectopic eruption of the mandibular first premolar.
