Custom Biodegradable Implants: Production Cycle and Technological Features

Reconstructive surgery is increasingly focused on personalized solutions. Custom implants are already being applied in practice, demonstrating higher effectiveness compared to typical mass-produced products. Manufactured based on medical imaging of a specific patient, they precisely match anatomical features, reduce the need for repeated surgeries, and improve treatment outcomes. At biodrook, a production cycle has been established for the manufacture of biodegradable bone implants based on 3D printing and the engineering precision required by modern medicine.

Digital Planning Approach

Planning begins with CT or MRI scans — the traditional foundation for implant modeling — and a technical assignment from the surgeon. Based on this input, a 3D model is created and adapted to the clinical task and the patient’s anatomy. This approach takes into account the type of lesion, bone structure, and specifics of surgical access. Unlike standard implant systems, there is no unified template here — each product is created individually.

A Material that Supports Regeneration

biodrook uses a biodegradable composite based on polylactic acid (PLA) with the addition of hydroxyapatite — a mineral that is the main component of bone tissue. The material is highly biocompatible and capable of gradually degrading in the body. At the same time, hydroxyapatite promotes osteointegration — the natural fusion of the implant with the bone — and stimulates the growth of new tissue.

Thus, the implant serves as a temporary support and a biological environment for regeneration.

3D Printing Technology: Adapted to Medical Applications

A key stage is the 3D printing of the individual product. Unlike conventional FDM methods that work with thermoplastics, the technology applied at biodrook allows for forming parts from a viscous composite material that is not suitable for standard printing. A proprietary engineering solution ensures geometric precision, porosity control, and structural stability of the product.

This opens possibilities for designing complex anatomical shapes with an adapted internal architecture that matches the biomechanical properties of bone.

Sterilization and Quality Control

After printing, the product undergoes low-temperature gas sterilization, which preserves the material’s physical and chemical properties while ensuring the sterility required for implantation. The final stage is quality control, which includes:
• verification of geometric parameters against the 3D model;
• assessment of structural integrity;
• verification of compliance with medical standards and technical specifications.

This ensures process stability and clinical safety of the final product.

Clinical Benefits

Custom biodegradable implants offer expanded possibilities in reconstructive orthopedics and traumatology, reconstructive surgery, maxillofacial surgery, and potentially in pediatric surgery. For physicians, this means better preoperative planning, shorter surgical times, and predictable outcomes. For patients — reduced risk of complications, fewer surgical interventions, more comfortable postoperative recovery, and no need for subsequent implant removal.

The development and production of biodegradable implants at biodrook is based on the integration of digital technologies, innovative materials, and strict quality standards. This enables the delivery of solutions that meet the demands of modern personalized medicine and establish a new level of surgical practice — particularly relevant for Ukraine.
