Implants with Porous Outer Layer and Methods for Manufacturing the Same

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to medical implants, especially dental implants, that feature a solid core surrounded by a sleeve with an outer porous layer and an inner non-porous layer. The unique manufacturing process involves creating the core and porous sleeve separately, then assembling them using precise techniques to avoid high-temperature exposure of the core. The porous surface promotes better integration with bone tissue while maintaining high mechanical strength of the implant.

Use CasesContent extracted from patent full text and abstract with AI.

• Dental implants for anchoring artificial teeth, crowns, or bridges
• Orthopedic implants such as bone anchors or joint replacements requiring strong bone integration
• Maxillofacial implants for facial reconstruction
• Implants in veterinary medicine for animals requiring long-term supportive structures
• Any medical implant where strong mechanical stability and good bone ingrowth are essential

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced mechanical strength of the implant by avoiding thermal degradation of the solid core
• Improved osseointegration due to the controlled, highly porous outer layer, allowing better bone growth into the implant
• Reduced risk of implant failure from microstructural changes in the core
• Customizable porosity and mechanical properties to match individual patient needs or implant locations
• Potential for lower infection rates and better long-term outcomes due to superior bone bonding
