The plan is to study a human total hip prosthesis with hydroxyl-apatite coating for chemical fixation to bone. MPa (2375 psi) 44.0 MPa (6400 psi) 2.4 MPa (350 psi) Mixture 2 525 kg/m3. Hydroxyl-apatite coatings permit an implant fixation far superior to current methods using either cemented or cementless techniques. The hypothetical mechanism of bone bonding is chemical. Orders of magnitude (pressure) 105 Pa +690 to +830 kPa, +100 to +120 psi 105 Pa 800 kPa, 120 psi 106 Pa. Bony defects up to 2 mm in depth were filled with bone within six weeks. The complete Jour line of accessories and consumables for fluid transfer in HPLC and LC is available from VICI Jour. The apatite-coated implants were rigidly fixed within three weeks with demonstrable bone formation up to the implant surface. 12328.20771 Psi (Psi) Visit 85 Psi to Megapascal Conversion Megapascal : The megapascal (symbol:MPa) is a non-SI unit for pressure, and is a x1000000 multiple of the Pascal unit. Uncoated prostheses were surrounded by fibrous tissue and were easily extracted from the femur at any postoperative time. In a canine total hip arthroplasty study, the apatite-coated implants proved far superior to the uncoated controls. In relation to the base unit of pressure > (pascals), 1 Psi (psi) is equal to 6894.7572932 pascals, while 1 Megapascals (MPa) 1000000 pascals. Always check the results rounding errors may occur.

Histologic sections confirm the close bonding between apatite coating and living bone. How to convert Psi to Megapascals (psi to MPa) 1 psi 0.0068947572932 MPa. In a plug implant study designed to discount mechanical retention, a bone bonding shear strength of 64 MPa (9280 psi) was achieved, comparable to the strength of cortical bone. The static tensile substrate bond strength of the apatite coating is in excess of 85 megapascals (MPa) (12,000 psi). Plasma-sprayed apatite coatings on titanium substrates overcome the fatigue problem.

Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types.Sintered hydroxyl-apatite implants form very tight bonds with living bone but are susceptible to fatigue failure. You can find metric conversion tables for SI units, as well as English units, currency, and other data. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.Ĭ provides an online conversion calculator for all types of measurement units. The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The definition of a pascal is as follows: The SI prefix "mega" represents a factor of It is the pressure resulting from a force of one pound-force applied to an area of one square inch.
The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. 1 MPa 145.03773773 psi 1 psi 0.0068947573 MPa. MPa to psi, or enter any two units below: Enter two units to convert From:
