[Latest progress in studies of self-setting calcium phosphate cement]

Area of Science:

• Biomaterials Science
• Orthopedic Engineering
• Materials Chemistry

Context:

• Traditional ceramic hydroxyapatite (HAP) bone materials present challenges in sintering and shaping.
• Self-setting calcium phosphate cement (CPC) is a non-ceramic alternative offering improved handling characteristics.
• CPC has demonstrated successful clinical applications in repairing calvarial bone defects since 1991.

Purpose:

• To present the latest advancements in self-setting calcium phosphate cement (CPC) research.
• To explore novel CPC formulations, including fast-setting and non-decaying types.
• To investigate the potential of CPC as a drug delivery system for bone regeneration.

Summary:

• Self-setting calcium phosphate cement (CPC) is a versatile biomaterial overcoming limitations of ceramic hydroxyapatite (HAP).
• Recent studies focus on optimizing the setting process, developing enhanced CPC variants (fast-setting, non-decaying, organic compounds), and evaluating its in vitro performance as a drug delivery system.
• CPC exhibits favorable characteristics for bone defect repair, including ease of production and application.

Impact:

• CPC shows promise as a standard material for repairing non- or low-load-bearing bone defects.
• Advancements in CPC technology could lead to improved clinical outcomes in bone regeneration.
• Further research may expand the applications of CPC in orthopedic and reconstructive surgery.
