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.
