Following insertion of a piece of Osteogen plug for sinus membrane repair, a 8x14 mm implant is placed with >40 Ncm with allograft (*) placed around the unpolished portion of the implant (Fig.3,4).  A 6x3 mm abutment is placed to hold periodontal dressing in place.  If the implant is shorter (11 mm), there will be less sinus issue.  In fact there is no postop sinus infection; the implant threads seems not be exposed 3 months postop (Fig.6).  Because of the large implant, it is loaded early (Fig.7 Temp Bond).  The crown dislodges and is recemented with resin cement 1 year 5 months post cementation (Fig.9).
