Create a 7-slide, 16:9 academic conference presentation (6-minute talk) on: "Biodegradable Magnesium and 3D-Printed Implants: The Future of Implant Materials" Audience: dentists and prosthodontics postgraduates. Type: literature review. DESIGN: - Clean, minimal, professional medical-science style. - Colours: deep teal (#0B4F5C) dominant, light teal-grey (#E8F1F3) backgrounds, one orange accent (#C2500A). Dark slides for the title and the last slide, light slides in between. - Fonts: Cambria for headings, Calibri for body (safe fonts only). - Max 4 short bullets per slide, body text at least 14 pt. One message per slide. - Use icons, stat callouts, a comparison table and cards. No clip art. - Leave a clearly marked picture area on each content slide. - NO college name, NO guide name, NO logos, NO watermarks, NO author name except "[Your name]". SLIDES (do not change any numbers): 1. Title: the title above. Subtitle: "A review of the literature | Department of Prosthodontics | [Your name]". 2. The problem with permanent implants: stat "Up to 33%" (surgical site infection reported with titanium fixation). Bullets: titanium is bioinert and stays for life; second surgery may be needed for discomfort or infection; a very stiff metal can cause stress shielding. 3. Why magnesium? Two stat cards: "45 GPa" (elastic modulus of Mg) vs "10-23 GPa" (cortical bone). Bullets: essential element (>300 enzyme reactions, about 60% stored in bone); dissolves in the body, no removal surgery; Mg2+ at 2.5-10 mM boosts bone-cell growth. 4. Why 3D print it? Subtitle: patient-specific shape, porosity and inner structure from CT/MRI data. Table (Technique | Strength | Limitation): SLM | high precision, dense parts | oxidation risk, costly; WAAM | fast, low cost, large parts | rough surface, coarse grains; Binder jet | low temperature, design freedom | porous, degrades fast; 3D gel printing | low oxidation, suits composites | weak, shrinks on sintering. 5. Relevance to dentistry: two cards. Card 1 "Membranes and screws": Mg GBR membrane in dogs almost fully resorbed in 3 months; resorbable screws fixed condylar fractures (5 and 6 patients); no second-stage surgery. Card 2 "Mg coatings on Ti implants": better bone-implant contact in animal studies; rabbit study 9.24% Mg gave better removal torque; antibacterial against periodontal pathogens. Highlighted line: "Evidence so far: lab and animal studies; no clinical trials for Mg implants". 6. Challenges and fixes (3 rows, challenge -> fix): fast corrosion and hydrogen gas -> alloying, coatings, anodization; loses strength too early -> coatings, up to 4.8-fold lower corrosion (binder jet); custom devices do not fit standard testing -> adapted rules, FDA 2017 additive manufacturing guidance. 7. Take-home messages: Mg implants dissolve as bone heals; 3D printing adds custom shape and porosity; dental evidence is mostly lab and animal work; next step is long-term in vivo data and standard test protocols.

This project explores the clinical need for magnesium (Mg) in dentistry, highlighting its advantages over traditional materials. It compares various 3D-printing techniques for dental applications, showcasing Mg-coated implants and their preclinical evidence. Additionally, it addresses translational barriers such as corrosion and strength challenges, proposing solutions like coatings. The project concludes by identifying evidence gaps and outlining future research priorities.
