Orthodontic & Restorative Intrusion
Fig.1 is taken 5 days post implant placement at #18-20 with periodontal dressing in place (D). The tooth #15 is supraerupted (Fig.1,2 arrow) with limited vertical space for restoration. Two mini-implants are being placed (Fig.3). Two months later, the affected tooth appears to have been intruded with formation of a diastema between the molars (Fig.4 *). A single unit provisional is fabricated at #18 with more occlusal contact distally (Fig.5 <) so that when the patient occludes, there is clearance between the rest of the dentition (Fig.6 *). The lingual mini-implant is removed at the patient's request. In approximate 1 month, the tooth #15 appears to have been intruded further with closure of the diastema. The buccal mini-implant is removed. The single-unit provisional is easily broken and dislodged. It is then splinted to the two anterior splinted units (Fig.5: #19 and 20).
