In fact 5x10 mm implant placement with guide requires using 5 mm cortical tap (Fig.1). When a 6x4 mm healing abutment is placed slightly supragingival, the clearance with the opposing supraerupted tooth is ~ 2 mm. It suggests that orthodontic intrusion is required for restoration. In fact the patient is incompliant with orthodontic mini-implant placement and retraction. When the implant at #31 is osteointegrated 4.5 months postop (Fig.2), it is used an anchor with an abutment and a provisional to intrude the opposing tooth.
