This case report describes the intrusion of a natural tooth located between two implantsupported
crowns after 7 months in function. The intruded first molar was 2.5-3 mm infraoccluded
and tilted lingually. After 4 months of serial proximal contact adjustment, the intruded tooth was
gradually rebounded to its normal position in complete occlusion with the opposing tooth. A new
crown was fabricated for the molar to obtain the optimal proximal contact with the adjacent crowns. At
the six-month follow up the tooth was still in its normal position. The potential mechanisms of tooth
intrusion are described and discussed.
