A unique biomimetic modification endows polyetherketoneketone scaffold with osteoinductivity by activating cAMP/PKA signaling pathway

, 2022
Osteoinductivity of a biomaterial scaffold can notably enhance the bone healing performance. In this study, we developed a biomimetic and hierarchically porous polyetherketoneketone (PEKK) scaffold with unique osteoinductivity using a combined surface ...

Reconstruction of frontal bone using patient specific implant poly-ether-ketone-ketone via a lateral nasal/lynch incision

Oral and Maxillofacial Surgery Cases, 2023
Trauma to the craniofacial structures can result in both functional and aesthetic defects. Mucosa lines the frontal sinus outflow tract (FSOT) from the frontal sinus to the nasal cavity and any obstruction to the flow of mucus can lead to complications ...

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Comparison of tensile bond strength of ball attachments made of different materials to root canal dentin after chewing simulation

BMC Oral Health, 2022
Background Debonding of ball attachments is one of the complications that annoy teeth supported overdenture wearers. The polyetheretherketone (PEEK) and polyetherketoneketone (PEKK) polymers are widely applied in the dental field.

Implant therapy in older patients: Prosthetic considerations and biomechanical implications for frailty/aging

Periodontology 2000, EarlyView.
Abstract Background Population aging is reshaping prosthodontic care for both partially and completely edentulous individuals. In older adults, conditions such as frailty, comorbidities, polypharmacy, and cognitive decline can have a direct impact on the biological and biomechanical demands of implant therapy, thereby influencing the success of implant
