Synthetic bone grafts are commonly used within orthopaedics to provide a bone void filler that resorbs and is replaced with bone during the healing process.Arthrexâs synthetic materials are designed to optimize the osteoconductive nature of the bone graft with microporosity and macroporosity.ynthetic bone grafts are commonly used within orthopaedics to provide a bone void filler that resorbs and is replaced with bone during the healing process.
Semi-synthetic oils (also called 'synthetic blends') are blends of mineral oil with no more than 30% synthetic oil designed to have many of the benefits of synthetic oil without matching the cost of pure synthetic oil. Motul introduced the first semi-synthetic motor oil in 1966.Lubricants that have synthetic base stocks even lower than 30% but with high-performance additives consisting of esters can also be considered synthetic lubricants.he technical advantages of synthetic motor oils include: 1  Better low-and high-temperature viscosity performance at service temperature extremes. 2  Better (higher) Viscosity Index (VI). 3  Better chemical and shear stability. 4  Decreased evaporative loss. 5  Resistance to oxidation, thermal breakdown, and oil sludge problems.
