Click and you’re done. That’s how easily you secure the crown and cap with Acuris. And it takes less time than it does to read this article about a truly ground-breaking innovation.
A conometric revolution
Acuris is based on Professor Marco Degidi’s conometric concept.Unlike screw- and cement-retained solutions, it uses friction retention to secure the crown and cap onto the abutment, making it a prosthodontist’s dream come true.
This whole new way of thinking works really well, as the clinical studies of Dr. Degidi’s original conometric concept have proven[i]. Now a select team of experts, scientists and engineers from Dentsply Sirona Implants have developed it further. The results of our thorough tests show that all samples maintain their stability over time under cyclic loading[ii]. In other words, Acuris gives dental professionals a high quality solution for fixed retention.
Save 15–25 minutes per patient
An obvious upside is the time needed to place the final crown. With screw retention you typically need 30 minutes, while cement retention takes around 40 minutes. The total chair time with Acuris is 15 minutes. This time-saving of 15–25 minutes represents a significant economic gain and frees time to accept more patients or perform other procedures.
An easier procedure with fewer complications
Acuris offers the easiest possible way to secure the crown. Simply put the crown and cap on the abutment and click once using the unique Fixation Tool. The crown is secured. With this simple procedure you can expect more predictable end results and with no screw access holes to cover, you can also improve esthetics.
Furthermore, the risk of technical complications[iii], such as lost screws, lost screw access fillings or chipping of veneering ceramics is considerably lower with Acuris. Studies also suggest that cement residue is associated with signs of peri-implantitis in over 80 % of cases[iv]. Since you do not use cement that risk is eliminated.
Another smart feature is that Acuris, although it is a fixed retention, can be retrieved by the clinician for extra-oral cleaning or maintenance and then put back just as easily.
Good news for the laboratory and the patient
If you are a laboratory technician, Acuris improves your regular workday. The workflow is more efficient and cost-effective given that the final cap has a pre-defined margin and there is no need to create a screw access hole.
Patients are better off too, as less time spent in the chair and more predictable, high-quality end results increase satisfaction.
To summarize, Acuris is something new—and more than capable of redefining fixed retention.
