Biomaterials
This is a dental materials study with no connection to plant science, gardening, or botany.
Researchers went looking for scientific studies on braces ties and orthodontic parts made from materials that break down naturally instead of ordinary plastic. After searching nearly 150 papers, they found that not a single one actually tested a real biodegradable version; all the candidates were just regular plastic. The takeaway is that this environmentally friendly dental technology is still just an idea, not a reality.
Key Findings
149 records identified across PubMed and Scopus, reduced to 148 after removing one duplicate
Only 6 studies reached full-text review, and none met inclusion criteria for biodegradable polymer ligatures
Excluded studies involved only conventional nonbiodegradable elastomeric ligatures, confirming a total absence of research on biodegradable orthodontic alternatives
chevron_right Technical Summary
A systematic review searching for research on eco-friendly, biodegradable orthodontic braces ligatures found zero qualifying studies, revealing that this dental technology doesn't actually exist yet despite being proposed as a solution to plastic waste from dental treatment.

Biodegradable Polymer Ligatures and Auxiliaries in Orthodontics: An Empty Systematic Review.
Orthodontic ligatures and auxiliaries are essential components of fixed-appliance therapy. Conventional materials are nonbiodegradable and require periodic replacement, contributing to clinical ine...

Sustainability in plant science refers to practices and systems that allow plant production and ecosystems to continue meeting human and environmental needs over long periods. This is particularly important in plant biology because plants are foundational to food security, carbon cycling, and
