Aim: To describe through a clinical case report the surgical sequence of rehabilitation with 3D-printed implants associated with maxillary sinus floor lift with synthetic regenerative materials, including biphasic bioceramic. Case Report: Patient had an agenesis of the upper left premolars (#12 and #13), a vertical bone deficiency caused by maxillary sinus' pneumatization, and a horizontal alveolar resorption around the missing teeth area. During the surgical procedures, incisions, detachment, and osteotomy were performed in the lateral region of the maxillary sinus. The sinus membrane was detached and lifted 10 mm. Then, a thick poly(dioxanone)-based synthetic resorbable membrane (Plenum) was inserted and adapted inside the sinus to protect the sinus membrane. After the osteotomies with sub-instrumentation, 3D-printed implants (Plenum) were installed in the #12 area (3.5mm x 11.5 mm; 30N) and #13 area (4.0mm x 10mm; 20N). The maxillary sinus was entirely filled with a biphasic bioceramic, HA/β-TCP (70:30) 500-1000 μm (Plenum) and covered by the same synthetic resorbable membrane. Connective tissue graft from the palatal area was positioned internally to the flap and stabilized with sutures to improve the vestibular tissue architecture. The entire surgical wound was sutured, and the tissues stabilized. No complications occurred in the postoperative period. Conclusion: The use of synthetic regenerative memberane and 3D-printed implants seems to be a promising option in areas of deficient bone remnants.

“…Additive manufacturing (AM) processes, also known as 3D printing, are present in several areas, ranging from small implants to large vehicle parts, passing through branches such as medicine and dentistry. [1][2][3] The solutions presented by these technologies are viable because they are customizable and low-cost. 4 Customization is an essential factor in the health area due to the complexity of human beings, and it is estimated that in the future, hospitals will have bioprinters for transplant demands.…”

The development of functional compounds for extrusion applied in the additive manufacturing of anthropomorphic simulators is interesting, as it guarantees the manufacture of a 3D model similar to the patient. These simulators find applications in therapies or laboratory tests involving x‐rays. In order to replicate human conditions in these tests, it is essential to create materials that closely match the properties of human tissue, including the smoothness of soft tissues and the hardness of the bone tissue. This study developed ceramic‐polymeric composites, where the tomography intensity of each mixture was measured experimentally. Combinations of acrylonitrile butadiene styrene (ABS) with zirconium oxide and basic bismuth carbonate allowed imitation of bone tissue. The samples containing zirconium oxide and basic bismuth carbonate presented results that exceeded the minimum limit and reached a value close to 2000 Hounsfield units (HU) with 12% basic bismuth carbonate content. Combinations of ABS with hydroxyapatite and aluminum oxide can imitate soft tissues. The use of a surfactant facilitated the mixing of ceramic filler with polymer. Finally, 3D printing of a physical model was performed using a dual extruder printer, allowing simultaneous printing of bone and soft tissue components.Highlights Material mimicking x‐ray attenuation similar to bone tissue.

“…The dental models obtained with 3D printing have been used in dental education for some time. Deployment of 3D scanners, of CBCT and of 3D printers has enabled the precise replication of real anatomical structures, achieving simulated dental models having a real clinical correspondent, which can be successfully used in dental education [ 34 , 35 ] The combination of traditional simulation techniques with digital simulation broadens the educational possibilities towards decision-making training and deliberate practice, which are less possible in traditional settings.…”

Background and Objectives: The ever more complex modern dental education requires permanent adaptation to expanding medical knowledge and new advancements in digital technologies as well as intensification of interdisciplinary collaboration. Our study presents a newly developed computerized method allowing virtual case simulation on modular digital dental models and 3D-printing of the obtained digital models; additionally, undergraduate dental students’ opinion on the advanced method is investigated in this paper. Materials and Methods: Based on the digitalization of didactic dental models, the proposed method generates modular digital dental models that can be easily converted into different types of partial edentulism scenarios, thus allowing the development of a digital library. Three-dimensionally printed simulated dental models can subsequently be manufactured based on the previously obtained digital models. The opinion of a group of undergraduate dental students (n = 205) on the proposed method was assessed via a questionnaire, administered as a Google form, sent via email. Results: The modular digital models allow students to perform repeated virtual simulations of any possible partial edentulism cases, to project 3D virtual treatment plans and to observe the subtle differences between diverse teeth preparations; the resulting 3D-printed models could be used in students’ practical training. The proposed method received positive feedback from the undergraduate students. Conclusions: The advanced method is adequate for dental students’ training, enabling the gradual design of modular digital dental models with partial edentulism, from simple to complex cases, and the hands-on training on corresponding 3D-printed dental models.
