Problem
Many conventional surgical implants are not biodegradable and may require a second operation for removal, while some degradable polymeric or ceramic alternatives present strength, reactivity, or inflammation concerns.
Why it matters
A resorbable implant material could reduce dependence on permanent hardware, but mechanical performance, degradation behavior, biocompatibility, and clinical safety must be independently established for each intended use.
Approach
The patent describes an organic nanocomposite combining nanoparticles from date seeds, pomegranate peels, and camel knee bone with polymers, plant gels, glycerin, and botanical dyes, then molding or sculpting the material into surgical implants.
Who may benefit
Potential beneficiaries include orthopedic and dental implant developers, biomaterials laboratories, medical-device manufacturers, surgeons evaluating resorbable fixation concepts, and processors of agricultural or animal-derived feedstocks.
Potential value
The disclosed formulation integrates several waste-derived nanoparticle sources with a specified binder, gel, plasticizer, and dye system and provides routes for forming screws, compression plates, and dental posts.
Background
Background
Orthopedic fixation commonly uses stainless steel, titanium, cobalt-chromium, magnesium alloys, polymers, or ceramics. Permanent metallic devices may need later surgical removal, whereas degradable polymers can have lower strength or tissue-reactivity concerns. Bioceramics resemble bone mineral composition but can present mechanical limitations or inflammation concerns. The disclosure therefore seeks an organic, biodegradable implant composite that uses readily available waste-derived materials while addressing the need for shaped medical and dental fixation components.
Technology overview
Technology overview
The claimed composite contains defined weight ranges of date-seed and pomegranate-peel nanoparticle starches, PVC, polylactic glycolic acid, acrylate adhesive, pure starch, several plant gels and gums, chicken-gut-oil-based glycerin, botanical dyes, and a balance of camel-knee-bone nanoparticles. The preparation method pyrolyzes or grinds the biological feedstocks, uses acid hydrolysis to produce nanoparticles, blends them with the polymeric and organic components, and forms screws, plates, or dental prostheses by molding, curing, washing, or sculpting.
Potential applications
Potential applications
- Potential development of resorbable bone screws after full preclinical validation.
- Potential development of surgical compression plates after mechanical and biological testing.
- Potential use in dental posts or other molded dental prosthetic components.
- Research platform for waste-derived nanoparticle biomaterial formulations.
Evidence-supported advantages
Evidence-supported advantages
- Uses date-seed, pomegranate-peel, and camel-bone-derived nanoparticles.
- Defines component ranges for a multi-ingredient implant formulation.
- Describes both composition preparation and implant-forming methods.
- Covers screw, compression-plate, and dental-prosthesis configurations.
Development stage
Development stage
Patent publication with a described composition and implant-forming method; independent validation and commercialization were not established.
Commercial opportunity
Commercial opportunity
The concept may support collaboration with orthopedic, dental, and biomaterials developers seeking resorbable fixation platforms. Translation would require reproducible manufacturing, sterilization, shelf-life, mechanical and fatigue testing, degradation and extractables studies, biocompatibility, animal studies, clinical evidence, regulatory assessment, and confirmation that every animal- or waste-derived input can meet medical-grade sourcing and quality controls.
