Copings are ready for veneering. |

| Venering and Cementation | ||||
| The final veneering of the Wol-Ceram restoration is done following standard procedures with any of the porcelains currently available such as Vita Alpha, Vita VM7, Noritake Cerabien, Jensen Creation AV, Vintage AL Esthetic Porcelain, and All-Ceram.
The strength of the Wol-Ceram coping allows it to be cemented with conventional cements used for PFM restorations. In-Ceram restorations can be bonded using Panivia 21 TC, Rely X from 3M, or by using most conventional cements. |
