Bioplastics

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

Background:

Recent advancements in dental materials and technologies have focused on 3D printing (3DP) for fabricating dental devices.
The biocompatibility of resin-based 3D-printed dental materials remains a significant concern due to incomplete polymerization and potential toxicity from residual monomers and post-processing agents.

Purpose of the Study:

To provide a comprehensive overview of the biocompatibility testing methods for 3D-printed dental materials.
To analyze factors influencing monomer release and cytotoxicity in 3DP dental applications.

Main Methods:

A systematic review of scientific literature was conducted using major search engines with specific keywords related to 3D printing in dentistry.
Data extraction focused on materials used, polymerization techniques, monomer release, cytotoxicity assessments, and biocompatibility testing protocols.

Main Results:

Limited studies currently address the cellular responses to 3D-printed dental resins.
Factors influencing monomer release and the effectiveness of post-curing treatments in mitigating cytotoxicity are critical considerations.
Various biocompatibility tests are employed to evaluate dental materials manufactured via 3DP.

Conclusions:

Despite regulatory standards, thorough biocompatibility investigation of new 3D-printed dental materials is essential.
Understanding and mitigating the risks associated with residual monomers and processing chemicals are vital for ensuring patient safety.
Further research is needed to fully elucidate the long-term cellular effects of 3D-printed dental materials.
