A 77-year-old man has multiple restorations.  His teeth have long roots (suggesting bruxism, Fig.1).  The #11-14 FPD dislodges.  Twenty days postop, he will travel to his home country and stays for 2 months.  Four months postop, he will leave again.  To strengthen provisional FPD stability and early final restoration, each implant will be placed at each edentulous area.
