Purpose: To evaluate the clinical performance of tooth supported crowns fabricated with Bio-High Performance Polymer® polyetheretherketone (BioHPP® PEEK) material copings processed by CAD/CAM technology and veneered with compatible indirect composite materials.
Materials and Methods: Sixty patients with endodontically treated teeth in the posterior region of oral cavity were selected and divided in to two groups. Group A (Control Group) with 30 teeth rehabilitated with conventional tooth supported porcelain fused to ceramic (PFM) crowns. Group B (Test group) with 30 teeth rehabilitated with CAD/CAM processed BioHPP® PEEK tooth supported single crowns. Crowns were assessed on functional and biological parameters at baseline; 06 months and 12 months posttreatment follow up. The inter-group statistical comparison was tested using ‘Chi-Square test’ or ‘Fisher’s exact probability test’ and intra-group comparison done using ‘Wilcoxon’s signed rant test’.
Results: On functional parameters of crown decementation, fracture of PFM/composite veneering, fracture of coping and incidence of wear of opposing teeth, evaluated using ‘Chi-Square test’, ‘Fisher’s exact probability test’ and ‘Wilcoxon’s signed rant test’ did not differ significantly (P>0.05). Similarly on biological parameters, statistically the distribution of bleeding on probing and plaque index among the cases studied did not differ significantly (P>0.05).
Conclusion: Within the limitations of this study, it can be concluded that the BioHPP® PEEK crowns processed through CAD/CAM technology can be considered as an effective and alternate treatment modality to PFM crowns in the stress bearing posterior region of oral cavity.
