TL;DR
This study compares the strength and failure patterns of telescopic overdentures made from PEEK and zirconia materials.
Contribution
The novel contribution is evaluating the fracture load resistance of PEEK and zirconia telescopic overdentures after thermocycling.
Findings
Zirconia overdentures showed significantly higher fracture load resistance than PEEK overdentures.
PEEK overdentures exhibited more favorable and repairable failure patterns compared to zirconia.
Abstract
Edentulous patients often face challenges with denture retention and stability, making telescopic overdentures a preferred prosthetic option. The choice of material critically affects the strength and longevity of these restorations. Therefore, it is of interest to compare the fracture load resistance of telescopic overdentures fabricated with PEEK and zirconia copings after thermocycling. Zirconia demonstrated significantly higher fracture load values (1298.4 ± 110.7 N) than PEEK (845.6 ± 92.3 N, p = 0.002), though PEEK showed more favorable, repairable failure patterns. While zirconia provides superior fracture resistance, PEEK remains advantageous for its light weight, flexibility and ease of repair, emphasizing the need for material selection based on clinical demands.
