Clinical Properties Of A Good Implant
Orthopedic implants are used to provide adequate biomechanical support to the bone.1 Selection of the correct material for an implant is vital for the clinical success of the implant.2 The choice of implant material depends on several factors such as:
There are several treatment options available for fracture fixation. Your orthopedic surgeon will be able to select an orthopedic implant best suited for you. Consult your doctor to know more about implants.
Implant Fatigue Limit:
The body’s weight and constant activity can place stress on the implant. Hence, the material should have favourable fatigue strength. This can help prevent brittle fracture (breakage or cracking of a material where no deformation can be identified).2
Implant Tensile Strength:
An implant material must have high tensile strength, that is, it should be able to withstand maximum stress or load without breaking and improve stability.2
Implant Fracture Toughness:
An implant material with high toughness can prevent fracture of the implants.2
Implant Corrosion Resistance:
The material used for the implant should be free from corrosion because corrosion can lead to roughness or weakening of the implant.2
Implant Elasticity:
An implant material with good elasticity will be able to uniformly distribute the weight and decrease the movement between the implant and bone, thereby increasing the device’s life span.2
Implant Biocompatibility:
The implant material should not lead to toxic or injurious effects on the surrounding body tissues.3
