Fig. 5 Fig. 6a Fig. 6b implant proceeds gradually and progressively. This helps avoid crown fractures due to internal or exter- nal tension between a ceramic crown and an all- ceramic abutment. Using a hybrid abutment approach, there is a choice of resin or ceramic base materials, from feld- spar ceramics to ceramics with a silicate base. This still leaves the interface to consider; here, the crown is best connected to the abutment using a res- in-based composite cement that facilitates the gradual transmission of forces; also, these cements are more stable bio mechanically than ionomer ce- ments or derivatives (Figs. 6a & b). Conclusion The establishment of a stable peri-implant seal to maintain gingival health around implant-supported restorations must be a primary objective of any im- plant treatment. The single-stage approach allows the establishment of an initial peri-implant soft-tis- sue attachment that will be preserved as the abut- ment is not removed; hence, no violation of the bio- logic space will occur, allowing for greater tissue stability and yielding better aesthetics and an im- proved bone and soft-tissue stability. The integration of digital technology (CEREC) in the implant/restorative process shortens the treatment time and reduces the cost for the patient. The SKY elegance abutment helps treat patients with predict- able results._ This article was first published in EDI Journal No 1/2016.
