Coated Bio-Implants with Osseointegration Promoting Property
Abstract

This innovative technology for bio-implants is designed to enhance osseointegration—the process by which implants integrate with bone. The technology leverages a specialized biodegradable coating applied via an advanced electrospinning method, which accelerates bone growth around implants such as dental, orthopedic, and cranio-maxillofacial implants.

The nanofiber-coated surface supports bone-implant integration, as demonstrated by gross specimen photographs and radiographs.

Problem Statement

Traditional bio-implants, whether coated or uncoated, typically suffer from slow osseointegration, taking 3 to 4 months to fully integrate with bone tissue. This slow integration process can delay recovery and prolong discomfort for patients. There is a pressing need for bio-implants that can achieve faster osseointegration to expedite the healing process, particularly in critical applications such as dental, orthopedic, and cranio-maxillofacial implants.

Uniqueness of the Solution
  • Biodegradable Osteogenic Nanofiber Coating: Includes Polycaprolactone, gelatine type A, dexamethasone, β-glycerophosphate, ascorbic acid, and hydroxyapatite, enhancing bone cell attraction and growth. 
  • Accelerated Osseointegration: The coating facilitates rapid differentiation of mesenchymal stem cells, speeding up bone regeneration and integration. 
  • Mimics ECM (Extracellular Matrix): The coating not only promotes healing but also mimics the natural bone environment, providing an ideal scaffold for bone growth.
Prototype Details

The prototype for the advanced bio-implant technology features a specialized biodegradable coating composed of Polycaprolactone, gelatin type A, dexamethasone, β-glycerophosphate, ascorbic acid, and hydroxyapatite. This composition has been proven to significantly accelerate osseointegration, reducing the typical integration period from 3-4 months to substantially less, thereby enhancing the implant's mechanical properties and promoting faster healing.

Current Status of Technology

The advanced bio-implant technology is currently at the prototype stage, with initial testing showing that its biodegradable coating significantly speeds up osseointegration, reducing typical recovery times. The technology is preparing for further clinical trials to validate its efficacy and safety, moving closer to potential clinical use.
