BioHPP: A New Alternative Material for Hybrid Implant Prosthesis
Background:
The most common problems with the framework materials in implant supported hybrid prosthesis which is one of the treatment options for edentulous patients are, it isn't as elastic as bone, low biocompatibility, non-esthetic appearance due to the reflection of gray opaque color of the framework material, chipping due to poor bonding to composite. BioHPP was introduced as an alternative to the other framework materials.
Aim:
The aim of this clinical case is to offer an alternative treatment approach with BioHPP framework to framework materials such as titanium, cr-co, zirconia and PEEK used in edentulous patients.
Materials-Methods:
A 67-year-old edentulous male patient presented to our clinic for fixed prosthesis. After planning, 6 Dentis (Dentis co Ltd, South Korea) implants on each upper and lower jaw were made. The treatment plan consisted of monolithic zirconia hybrid prosthesis for the upper jaw and Toronto prosthesis for the lower jaw due to aesthetic and mechanical advantages. Despite the use of an angled multiunit, Toronto prosthesis was preferred because the exit profiles of of some screws were located on the buccal side. Open impressions were taken from the lower and upper jaws using custom open tray. After recording the relationship between the jaws, the framework production phase was started. Monolithic zirconia was preferred as the framework material for the upper jaw. For the mandible, BioHPP-based (BioHPP, Bredent GmbH, Senden, Germany) Toronto prosthesis were restored with IPS empress crowns.
Results:
Hybrid prosthesis treatment was applied to the lower and upper jaws, and the patient was treated in terms of function, aesthetics and phonation. There were no complications in the 2-year follow-up of the case. Satisfactory feedback was received from the patient in terms of functionality and aesthetics.
Conclusion:
After 2 years of usage, BioHPP is as successful as the opposing monolithic zirconia upper jaw. The reason why BioHPP is preferred as framework material in implant-supported hybrid prostheses is that it is lighter than other framework materials, shows high aesthetics, is non-allergenic, biocompatibility, close to bone elasticity module, high connection with composite. The limitation of the use of BioHPP is the lack of sufficient scientific studies regarding its mechanical durability by time.
