Abstract
Wettability, stainability and diffusion properties of polymer (PMMA) based nanocomposites (PMMA/ZnO) have been explored with critical significance to their physicochemical perspectives and clinical implications in the maxillofacial rehabilitation of cancer and trauma patients. Wetting and diffusion of artificial saliva through the neat polymer and nano composites have been investigated in detail. The same protocol was adopted for water diffusion studies at different temperatures. Transportation mechanism and surface wettability and stainability by commonly used beverages like tea, coffee and turmeric on these composites are studied in detail. Inferences are correlated with morphological analysis by Atomic Force Microscopy (AFM) and surface roughness parameters and density measurements. No studies have been reported till date about correlating wetting enhancement to retentive qualities and diffusion resistance to anti-stainability of the prostheses in the biomedical field. Findings of the present study is highly relevant and promising as these membranes/composites offer better retention and adaptability for the prostheses on tissue base which stimulates blood circulation in that region which prevents further bone resorption. Anti-staining potential offer more acceptance and durability for the maxillofacial prostheses especially intra orally. This nano formulation is a highly durable, cost effective esthetic substitute for the conventional polymer PMMA.
