Osteointegrated Implant as Anchorage
The tooth #18 of a 22-year-old lady is tilted and shifted mesially (Fig.1 <). When the implant at #19 osteointegrated (3 months postop, Fig.2 I), a narrow abutment (A) is placed before the tooth #17 is extracted (X).
Four to five months of comprehensive orthodontic treatment, the tooth #18 is distalized (Fig.3 black arrowhead: >). Surprisingly, there is coronal growth of bone between the implant and the tooth #18 (white arrow, compare with Fig.1,2). These two changes are beneficial to the health of the tooth #18 .
Fig.4 is 5 years post cementation. A large abutment has been used for a better profile. Additional benefit of comprehensive orthodontic treatment is shown next.
