From Magic Split to Magicore

The ridge is wide at #14 11 months post socket preservation.  Access and bone expansion (BEB) starts with Magic Split, followed by Magic Expanders 3.0, 3.8 and 4.3 mm from 8 to 9 mm for sinus lift.  No bone is removed for osteotomy.  Instead bone condensation occurs.  After placement of a 4.5x11 mm dummy FC implant (Fig.1 with sinus lift (without bone graft)), a 5x9(2) mm Magicore (2 mm cuff) is placed with >55 Ncm with cuff margin at the gingival margin (Fig.2); a 5.5x3 mm solid abutment tries in.  There is no occlusal clearance; trimming of the solid abutment will be needed.  Later a healing screw is placed (Fig.3 *).  There is no bone loss 5.5 months postop (Fig.4).  A healing cap is placed without much tissue blanching.  Instead a 5.5x3 mm solid abutment is placed; after height adjustment, impression is taken.  A permanent crown is temporarily cemented 6 months postop (to rule out food impaction) and permanently re-cemented 7 months postop (Fig.5,6).  CBCT taken 3-4 months post cementation shows that the implant threads are within the bone (Fig.7) and that the implant barely enters the sinus (Fig.8 *).  That is significant since the patient has chronic sinusitis with thickened sinus membrane (Fig.9 *).  The tooth #18 seems to have crazing line 10 months post cementation of the crown at #14 (overloading, Fig.10).
