Purpose: This study was conducted to measure the difference between Chrome Cobalt telescopic crowns and Poly ether ether ketone [PEEK] telescopic crowns retaining implant retained partial overdenture regarding implant stability, crestal bone height changes and periodontal pocket depths. Materials and Methods: This study was made on fourteen lower kennedy class I partially edendulous patients. All patients received posterior implant in the second molar area in each side. The patients were divided into 2 groups, the first group received chrome cobalt telescopic crown and the second group received poly ether ether ketone telescopic crowns over the implants. Partial overdenture was constructed for all the patients in the two groups. Patients were followed up clinically to measure crestal bone height changes using cone beam ct, implant stability test using osstell and periodontal pocket depths. Results: Both groups showed increase in implant stability, periodontal pocket depths and decrease in crestal bone height, however the difference between the two groups were non-significant except in the periodontal pocket depth, the chrome cobalt group showed increased pocket depths than the PEEK group. Conclusions: From the results of this study the, the following conclusions could be obtained. There was almost no difference in crestal bone height resorption between the CrCo and the PEEK telescopic crowns, the difference between implant stability in both groups were non-significant, at the end of the follow up period, the PEEK telescopic crown group showed lesser periodontal pocket depths than the CrCo group which suggests that the PEEK is more biocompatible than the metallic crowns.
