This 77-year-old patient was already supplied with multiple implants and wanted the gap 23 to 25 to be filled with a fixed bridge (Fig. 30). Since it was a FP 3 option or indication according to C.E. Misch and hygiene deficits of patients had to be corrected with thehelpofaprofessionaldentalcleaning,inthiscase we decided to manufacture, similar to the previous case,aremovablebridgewhichwasneithercemented nor bolted. Theprocesswascorrespondingtothecasebefore. Thedifferencewasthatwewereusingporcelainfused tometal.Thebridgewasgluedinthemouthtothetwo PEEK caps (Figs. 31, 32a & b). Now, the patient has a verygoodchewingcomfort.Theprosthesiscanbere- moved from the prophylaxis assistant very well. The problem of a cemented bridge with the appropriate cement residues, a possibly too strong adhesion and a difficult retrieve possibility was avoided as well as thedisadvantagesofscrewing.Theuseofceramicve- neers fused to the secondary parts is possible and chipping avoided (Fig. 33).
