Implants in the Same Arch with Guide Should be Placed Together    

Today schedule is to extract the teeth #4 and 5 and place an implant at #5.  When the latter is done, it appears that the implant at #15 should be placed at the same appointment (Fig.1).  Once an abutment is placed at #5 (Fig.2 A, 5) for temporary crown (Fig.4 T) , the guide may be not seated again unless the crown is removed.  Luckily the implant placement at #15 is quick and smooth with the guide (Fig.3,6).  The implants seem to be covered by the bone 4 months postop (Fig.7,8).  #15 abutment screw needs retightening because of long crown 1.5 months post cementation.  Access hole is palatal.  There is premature contact in lateral movement.  The buccolingual occlusal table is large at #14 and 15.  In fact there is more occlusal contact at #14 than #15 in centric occlusion.  Tissue level implants should have been placed to reduce implant/abutment loosening.  The incomplete abutment seating (Fig.5,7) is noted after retightening the loose cantilever FPD 1 year post cementation (Fig.9 <).  After removal of the FPD, the abutment is reseated  completely without interference of the proximal contacts (Fig.10).
