LOCAL FABRICATION OF FOUR-UNIT DENTAL FLASK IN RELATION TO IMPORTED ONES WITH LOCAL CONTENT

This project focuses on the local fabrication of a four-unit dental flask and its comparison with imported dental flasks used in dental technology laboratories. Dental flasks are essential devices used in the processing of dentures and other prosthetic appliances in prosthodontics. The high cost of imported dental flasks, limited accessibility, and dependence on foreign products have created challenges for dental laboratories and institutions in developing countries. This study was carried out to design and fabricate a locally produced four-unit dental flask using available local materials while evaluating its effectiveness, durability, thermal conductivity, dimensional stability, and economic advantages in relation to imported dental flasks. The fabrication process involved material selection, pattern making, casting, machining, finishing, and assembly of the dental flask components. Locally sourced aluminum alloy and mild steel materials were used due to their availability, strength, corrosion resistance, and affordability. Comparative analysis was conducted between the locally fabricated flask and imported dental flasks based on performance, cost efficiency, maintenance, adaptability, and laboratory application. Findings from the study revealed that the locally fabricated four-unit dental flask demonstrated satisfactory mechanical properties and functional efficiency comparable to imported flasks. The locally fabricated flask also reduced production costs significantly and promoted local technological advancement. The study concluded that local fabrication of dental laboratory equipment is feasible and beneficial for improving self-reliance, reducing import dependence, and encouraging indigenous innovation in dental technology practice. Recommendations were made for further improvement in material finishing, precision machining, and institutional support for local manufacturing industrie
