Trends in 3D Printing Implants for Medical and Dental Applications

Hydroxyapatite (HA) and HA-based nanocomposites have been recognized as ideal biomaterials in hard tissue engineering because of their compositional similarity to bioapatite. However, the traditional HA-based nanocomposites fabrication techniques still limit the utilization of HA in bone, cartilage, dental, applications, and other fields. In recent years, three-dimensional (3D) printing has been shown to provide a fast, precise, controllable, and scalable fabrication approach for the synthesis of HA-based scaffolds. This review therefore explores available 3D printing technologies for the preparation of porous HA-based nanocomposites. In the present review, different 3D printed HA-based scaffolds composited with natural polymers and/or synthetic polymers are discussed. Furthermore, the desired properties of HA-based composites via 3D printing such as porosity, mechanical properties, biodegradability, and antibacterial properties are extensively explored. Lastly, the applications and the next generation of HA-based nanocomposites for tissue engineering are discussed.

3D printing and digital manufacturing technologies have been largely used in dentistry in recent years and dentists and prosthetic technician are up to date and involved in the subject, following the advancement of technology. The objective of the present manuscript was to carry out a descriptive literature review, covering the processing methods, precision, types of materials used and the applications of 3D printing in dentistry. A bibliographic search was conducted in the PUBMED database (www.pubmed.gov), in which studies published from 2000 to 2020 were collected. Laboratory studies, case reports, systematic and literature reviews were included. Therefore, articles that did not address the topic in question, letters to the editor, opinion articles, duplicate literature and texts that were not in English were excluded. According to the inclusion and exclusion criteria, 75 research articles were selected. In dentistry the most common methods of 3D printing used are: stereolithography (SLA), material jetting (MJ), binder jetting, and Laser sintering. It is important to carefully consider the limitation of each method, material and operator’s skills in 3D printing for this technology to be more affordable in dentistry. Despite that, the accuracy of printing methods and materials used in different dental applications with 3D printing have been improving each day more, allowing a digital workflow with greater applicability and frequency of use in dentistry.

Dental Applications

Poly(methyl methacrylate) (PMMA) is widely used in dental applications. However, PMMA specialized for stereolithography (SLA) additive manufacturing (3D-printing) has not been developed yet. This study aims to develop a novel PMMA-based resin for SLA 3D-printing by mixing methyl methacrylate (MMA), ethylene glycol dimethacrylate (EGDMA), and PMMA powder in various mixing ratios. The printability and the viscosity of the PMMA-based resins were examined to determine their suitability for 3D-printing. The mechanical properties (flexural strength and Vickers hardness), shear bond strength, degree of conversion, physicochemical properties (water sorption and solubility), and cytotoxicity for L929 cells of the resulting resins were compared with those of three commercial resins: one self-cured resin and two 3D-print resins. EGDMA and PMMA were found to be essential components for SLA 3D-printing. The viscosity increased with PMMA content, while the mechanical properties improved as EGDMA content increased. The shear bond strength tended to decrease as EGDMA increased. Based on these characteristics, the optimal composition was determined to be 30% PMMA, 56% EGDMA, 14% MMA with flexural strength (84.6 ± 7.1 MPa), Vickers hardness (21.6 ± 1.9), and shear bond strength (10.5 ± 1.8 MPa) which were comparable to or higher than those of commercial resins. The resin’s degree of conversion (71.5 ± 0.7%), water sorption (19.7 ± 0.6 μg/mm3), solubility (below detection limit), and cell viability (80.7 ± 6.2% at day 10) were all acceptable for use in an oral environment. The printable PMMA-based resin is a potential candidate material for dental applications.

Objective: To evaluate the applications of 3d printing /additive manufacturing (AM) in dental education & clinical dentistry and elaborate various 3d printing technologies, its benefits, limitations and future scope. Methods: Research papers on the application of 3d printing in dentistry were searched in Scopus and Pubmed and studied using bibliometric analysis. This review briefly describes various types of 3d printing technologies with their accuracy, use of different materials for 3d printing and their respective dental applications. It also discusses various steps used to create 3D printed dental model using this technology. Furthermore, the application of this technology in dental education and various clinical procedures are discussed. Results: 3d printing is an innovative technology making a paradigm shift towards treatment customization. It helps in customized production of dental implants, surgical guides, anatomic models etc. using computer-aided design (CAD) data. This technology coupled with state-of-the-art imaging techniques and CAD software has enabled, especially oral surgeons to precisely plan and execute complex surgeries with relative ease, high accuracy and lesser time. 3d printing is also being utilized in other disciplines of dentistry to prepare aligners, crown and bridge, endodontic guides, periodontal surgery guides, surgical models for treatment planning and patient education. Alongside its possibilities have also been explored in preclinical skills in operative, endodontics etc. KEYWORDS 3D printing; Additive manufacturing; Dental applications of 3d printing.

The objective of this paper is to present the thermal behavior of various PMMA/TiO2 nanocomposite for complete dentures fabrication with 3D printing technology. There have been prepared and thermally characterized polymeric composites with varied nanofiller content ranging between 0.2% and 2.5% (w/w%). The nanocomposites proved a better thermal performance than that of pure copolymer PMMA-MMA or 3D printing PMMA polymer complex matrix. A small difference in glass transition (Tg) temperature for all compounds studied was recorded.
