This series of cases depicts a new “all-at-once concept” described in 2016 for instantly placed single anterior implants that are immediately restored with a definitive Crown on type 1 socket.
The final crown is fabricated beforehand on the natural tooth to be extracted and then picked up with a polyvinyl siloxane (PVS) impression. In the laboratory, computer-guided or model-based implant surgery is simulated on the master cast. The final zirconia abutment is fabricated on the same model and retrofitted to the definitive crown to construct a screw-/ cement-retained implant restoration.
Critical aspects are explained in detail in this lecture with detailed videos of some of the cases presented at 5 years.
Benefits of the all-at-once concept:
- The all-immediate approach of the procedure allows for significantly faster healing and less trauma, which translates to patient satisfaction
- The ASC abutment design provides great versatility and ideal implant placement
One of the disadvantages is that this concept is technique-sensitive and requires a certain level of expertise as well as excellent communication between the clinician and the dental technician.
