Validity of PEEK PSI Containing Autogenous Bone Graft for Maxillary Reconstruction Following Lesion Enucleation

2017-08-29 20:23:21 | BioPortfolio


Surgical ablation of large maxillary cysts usually results in considerable hard and soft tissue deficits that ultimately affect the final esthetic and functional outcomes. Reconstruction of such defects; whether primarily or secondarily; offers much better long-term outcomes Gellrich NC, Schramm (2002). However, primary bony reconstruction becomes potentially complicated in many cases of such large cysts encroaching or involving the maxillary sinus where a communication with the maxillary sinus lining may be unavoidable Eckardt A, Swennen (2005).

Reconstruction of such defects can be accomplished using either vascularized or; more commonly; non-vascularized autogenous bone grafts. Different bone substitutes remain to be another viable option. The simultaneous use of titanium meshes provides physical three-dimensional support for the bone graft contained within as well as the overlying soft tissues Lethaus, et al (2010). However, the drawbacks of titanium meshes in such defects remain to be mainly the difficulty in adequately shaping the mesh and the lack of proper isolation of the mesh contents from the maxillary sinus cavity Kokemueller H, et al (2008).

Medical and Biotech [MESH] Definitions

One of three members of the ether-a-go-go (EAG) POTASSIUM CHANNELS gene family comprising ether-a-go-go (eag), eag-like (elk) and eag-related (erg) subfamilies. Ether-a-go-go-related gene 1 (ERG1) also known as KCNH2, encodes the pore-forming subunit of a rapidly activating-delayed rectifier potassium channel that plays an essential role in the final repolarization of ventricular action potential. Loss-of-function mutations in human hERG1 is associated with life-threatening ARRHYTHMIA.

A family of voltage-gated potassium channels that are characterized by long N-terminal and C-terminal intracellular tails. They are named from the Drosophila protein whose mutation causes abnormal leg shaking under ether anesthesia. Their activation kinetics are dependent on extracellular MAGNESIUM and PROTON concentration.
