“…Maher, S., et al (2021) noted that additively manufactured titanium implants have host cell attachment and bone mineralization and can potentially provide antibacterial protection [ 64 ]. The good condition of the peri-implant tissues was confirmed by the radiographic examination in many cases for the RAI implantation with a high survival rate within a year to three year follow-up [ 10 , 12 , 65 , 66 ].…”

“…While conventional conic implants are machine milled and only available in standard sizes and diameters (narrow, medium, large), PBF RAI would have the advantage of allowing the fabrication of dental implants with customized sizes and diameters. This feature would permit immediate placement of dental implants after tooth extraction, avoiding a second surgery and reducing the healing time [ 12 ].…”

Over the past couple of decades, additive manufacturing and the use of root-analogue-printed titanium dental implants have been developed. Not all powder particles are sintered into the final product during the additive manufacturing process. Reuse of the remaining powder could reduce the overall implant manufacturing cost. However, Ti-6Al-4V powder particles are affected by heat, mechanical factors, and oxidization during the powder bed fusion manufacturing process. Degradation of the powder may harm the final surface composition and decrease the biocompatibility and survival of the implant. The uncertainty of the recycled powder properties prevents implant fabrication facilities from reusing the powder. This study investigates the chemical composition of controlled, clean, and recycled titanium alloy powder and root-analogue implants (RAI) manufactured from these powders at three different depths. The change in titanium’s quantity, oxidization state, and chemical composition in powder and RAI implants have been demonstrated and analyzed. While not identical, the surface chemical composition of the recycled powder implant and the implant manufactured from unused powder are similar. The results also indicate the presence of TiO2 on all surfaces. Many studies confirmed that titanium dioxide on the implant’s surface correlates with better osteointegration, reduced bacterial infection, and increased corrosion resistance. Considering economic and environmental aspects, surface chemical composition comparison of clean and reused powder is crucial for the future manufacturing of cost-effective and biocompatible implants.

“…[183][184] Bioprinting offers three main classes: extrusion-based bioprinting, laser-assisted bioprinting, and droplet-based bioprinting; in extrusion bioprinting, pressure is applied on a bioink to deposit filaments following a defined pattern. [185] Laserassisted bioprinting (LAB) employs a laser as its energy source to precisely deposit biomaterials onto a substrate, and the droplet-based method involves the deposition of bioink droplets through the printhead. [186] Single-phasic scaffolds are simple and have applications, but they often fall short of replicating the complexity and functionality of native tissue.…”

Gingival recession, a prevalent condition affecting the gum tissues, is characterized by the exposure of tooth root surfaces due to the displacement of the gingival margin. This review explores conventional treatments, highlighting their limitations and the quest for innovative alternatives. Importantly, it emphasizes the critical considerations in gingival tissue engineering leveraging on cells, biomaterials, and signaling factors. Successful tissue‐engineered gingival constructs hinge on strategic choices such as cell sources, scaffold design, mechanical properties, and growth factor delivery. Unveiling advancements in recent biofabrication technologies like 3D bioprinting, electrospinning, and microfluidic organ‐on‐chip systems, this review elucidates their precise control over cell arrangement, biomaterials, and signaling cues. These technologies empower the recapitulation of microphysiological features, enabling the development of gingival constructs that closely emulate the anatomical, physiological, and functional characteristics of native gingival tissues. The review explores diverse engineering strategies aiming at the biofabrication of realistic tissue‐engineered gingival grafts. Further, we highlight the parallels between the skin and gingival tissues, exploring the potential transfer of biofabrication approaches from skin tissue regeneration to gingival tissue engineering. To conclude, the exploration of innovative biofabrication technologies for gingival tissues and inspiration drawn from skin tissue engineering look forward to a transformative era in regenerative dentistry with improved clinical outcomes.This article is protected by copyright.
