Abstract
Summary & conclusions
Polyetheretherketone (PEEK) is a new group of materials which is
introduced recently as non-metallic replacement of metal or zirconium
frameworks in different fixed and removable prosthetic applications 228.
PEEK offers patients a metal-free alternative to conventional prostheses
made from dental alloys, which in certain cases can adversely affect patient
health.
This research was carried out to study the clinical and radiographic
effects of using BioHPP abutment (ceramic filled PEEK abutment) in
comparison to cast CrCo abutment in fixed-detachable implant supported
mandibular partial dentures. Seven partially edentulous patients have class I
Kennedy classification with the 1st premolar as the last standing tooth at both
sides in the age range of (40-55) years old were selected from Prosthodontics
Outpatient Clinic, Faculty of dentistry, Tanta University.
Two implants were placed at each side at the position of second
premolar and second molar. After 3m healing period, One side was restored
with fixed detachable partial denture made of Bio- Hpp material (group 1)
and the other side was restored with fixed detachable partial denture made of
cast CoCr material (group II), (Split mouth study). Both partial dentures
were veneered with visiolign composite material.
Each case was evaluated clinically as regard to (success rate, modified
bleeding and plaque index, Probing depth) and radiographically using digital
panoramic radiograph and Sidexis XG software to measure the (marginal
bone loss and perimplant bone density) at baseline (partial denture insertion)
and after 6 and 12 months. Data were collected and statistically analyzed.
There was no statistically significant difference between the two groups
(P<0.05).
