Case in brief
A 56-year-old woman with extensive mandibular tooth loss received a tooth-supported telescopic prosthesis made with a polyetherketoneketone (PEKK) primary crown and framework. The prosthesis was designed and fabricated digitally using intraoral scanning, computer-aided design, milling, and 3D-printed casts. At four-year follow-up, retention, mastication, aesthetics, and biological outcomes were favorable, with no significant wear or decline in retention force reported.
What made this case unusual
The case demonstrates a digitally fabricated PEKK telescopic prosthesis for extensive mandibular tooth loss, with retention maintained and no significant wear reported over four years.
Diagnostic / clinical pearl
PEKK can be used in a digitally fabricated, natural-tooth-supported telescopic prosthesis; this case reported sustained retention and no significant wear at four-year follow-up.
