Isixhumi se-SC/PC sitholakala kuzo zombili izinguqulo zemodi eyodwa kanye ne-multimode, futhi sihambisana ngokugcwele ne-Bellcore.Zombili izinguqulo zemodi eyodwa kanye ne-multimode ziza ne-zirconia ceramic ferrule enephrofayili ye-PC epholishwe ngaphambili kanye nesiphetho esiyindilinga esiyi-convex.Lokhu kuvumela ukupholishwa ngokushesha kwefayibha futhi kwenza isifaki sifinyelele ukulahlekelwa okuphansi kokubona, kuyilapho siqinisekisa ukuphindaphinda okuphezulu.
Zonke izixhumi ze-SC/APC ziza ne-zirconia ceramic ferrule enenketho yezinhlobo zobuso bokugcina okuhlanganisa okujwayelekile, isinyathelo, nekhoni.Lezi zinhlobo zobuso bokugcina zivumela ukupholisha ngokushesha, nokulahlekelwa kokufaka okuphansi kanye nokubonakala kwangemuva, kuyilapho kuqinisekisa ukuphindaphinda okuphezulu.
