A Review on 3D Printing of Partially Absorbable Implants

Husain, Minhaz / Singh, Rupinder / Pabla, B. S.

Implants/scaffolds are being used extensively in various dental/orthopedic applications for humans as well as VP. In the past five decades, several studies outlined the use of metallic, ceramic, and polymeric implants for such applications. As per the reported literature, the implants/scaffolds should be biocompatible and have thermal–physical properties near the natural bone. Most implantable materials have biocompatibility, but they fail on the ground of thermal physical properties (closer to natural bone) leading to problems like stress shielding. Among the various available solutions for preparing customized implants with properties close to the natural bone, 3D printing has been considered one of the viable material processing routes for bioabsorbable material with 4D capabilities. This article highlights the review of the material processing through 3D printing as inclusion criteria for the preparation of partially absorbable implants as a laboratory-scale solution in the form of bibliometric analysis. Finally, a systematic framework has been presented followed by a short case study for the fabrication of a 3D-printed partially absorbable implant for VP. For bibliometric analysis, the Web of Science database for the past 20 years was explored by keeping a minimum no of term occurrences 10 for the selected keywords. By selecting the top 60% of terms relevance score table was generated. The bibliometric result suggests that in the past 20 years, the trend for 3D-printed implants has been significantly increased (72 out of 311 articles were published in 2022 alone, while in 2020, 53 articles were published). It has been observed that for 3D-printed partially absorbable implants, the maximum studies have been reported on the metallic implant, and very limited have been reported on the polymer-based absorbable implants.
