Advantage of Simultaneous Immediate and Delayed Implants

Two and half months after #30,31 implant placement,  the 50-year-old male patient returns for #14 (immediate), 15 implant placement.  The tooth #14 is loose.  The socket will be treated with 2% Xylocaine; 1:50,000 Epinephrine as a control of antibiotic study.  His bone density is high in the mandible and expected to be so for the maxilla, especially at #15 (Fig.1).  Bone width is no problem from clinical observation.  The biggest challenge is bone height.  The septum at #14 should be low.  Anyway, the SM implants do not have to be wide as long as primary stability is obtained.  Bone harvested from the sites of #14 and 15 will be placed at the former site.  This is an advantage of simultaneous immediate and delayed implants.  The mesiodistal width of the site of #15 is narrow (Fig.1), probably due to mesial shift and tilt of the tooth #16 (arrow).  Therefore the diameters of the implants at #14 and 15 should not be large (Fig.2).
