In complete denture fabrication, when pre-extraction records are lacking, determining the denture teeth positions to where the natural predecessors occupied is essential yet challenging. Although several biometric guides were suggested to position teeth for dentures, none is providing three-dimensional (3D) positions of teeth that can be used in the recently developed computer designed digital dentures. The aim of this study was to develop new biometric guides to determine the original 3D positions of the maxillary teeth and dental arch form individualised for each given dentate or edentulous maxillary cast based on selected intraoral landmarks. The objectives were to investigate the …

Background: The purpose of tissue expander is to grow healthy supplementary tissue under the controlled of mechanical force exerted by the tissue expander. In the field of reconstructive and plastic surgery, the use of soft tissue expanders are important for growing healthy supplementary tissue. However, the molecular mechanism associated with the inflammatory response associated with the force generated from the use of tissue expanders is still not characterized. Among the many types of tissue expanders, anisotropic type of hydrogel tissue expander was chosen due to its ability to produce controlled incremental inflation on the tissue that enhance cellular adaptation and …

A slightly branched urethane acrylate macromer (UAM) was synthesized by reacting palm oil-based polyol with excess amounts of polymeric methylene diphenyl diisocyanate (MDI) to form urethane prepolymer, then reacted with 2-hydroxyethyl methacrylate (HEMA) and FT-IR spectroscopy confirmed the urethane and grafted acrylate groups. 0.2% by weight of camphoroquinone (CQ) and 0.8% by weight of ethyl-4-N,N-dimethylamino-benzoate (4EDMAB) by weight were added to render the experimental resins light-curable. Their viscosity, percentage of degree of conversion (%DC) and cross-linking density (CLD), percentage of volumetric polymerization shrinkage (%VPS), water sorption and solubility, flexural strength, modulus of elasticity and toughness were determined and compared to …
