Ceramics Used As Biomaterials

In gen eral these materials can be divided into the fol lowing categories.

Ceramics used as biomaterials.

These material properties are utilized to produce number of commercial and domestic products such as pottery bricks advanced functional items etc. Metals polymers ceramics and composites. Types of biomaterials ref 1 most synthetic biomaterials used for implants are common materials familiar to the average materials engineer or scientist table 1. Table 1 examples of medical and dental materials and their.

Ceramic biomaterials bioceramics the class of ceramics used for repair and replacement of diseased and damaged parts of the musculoskeletal system are referr slideshare uses cookies to improve functionality and performance and to provide you with relevant advertising. Ceramic materials can be identified by their general properties like high hardness brittleness chemical stability and low thermal conductivity. These are the materials that degrade in the body while being replaced with regenerating tissues 2 hydroxyapatite ca 10 po 4 6 oh 2. Bioceramics and bioglasses are ceramic materials that are biocompatible.

Advanced ceramics and traditional ceramics are the main categories of ceramic materials. Indeed the wide variety of these materials in terms of composition. A review of classes of biomaterials and their applications is presented. But they are also interesting for a large number of other applications in the dental and bone reconstruction fields in particular.

Ceramics have been used as biomaterials for millennia. Bioceramic materials currently used for the repair and reconstruction of hard and soft tissues can be categorized according to composition structure and properties. Only within the last 50 years have medical ceramics been incorporated into load bearing applications. These biomaterials are grouped into bioinert ceramics as alumina and zirconia bioactive glasses and glass ceramics and bioresorbable calcium phosphates based materials.

Particular interest is paid to bioceramics calcium phosphates and hydroxyapatite which are the leading biomaterials. Plaster of paris which is made of calcium sulphate hemihydrate caso4 h2o is also used in radiotherapy to make immobilization casts for patients and in dentistry for modeling of oral tissues. Hydroxyapatite can chemically bond rapidly with bone due to chemical similarities and was first used in the 70 s before being accepted as an implant material in north america in 1988.
