Intrusion for Restoration

A 37-year-old man has sign of bruxism (short clinical crowns).  The crown at #18 has history of repeated dislodgement with periapical lesion (Fig.1 <), accompanied with supraeruption of the opposing tooth (#15).  Treatment consists of intrusion of #15 with 2 mini-implants, retreatment of RCT for #18 and new restoration and immediate implant at #2.  Fig.2 is taken 2 years after intrusion.

Without intrusion at #31, the implant crown at #2 needs recementation several times.
