Soseikai General Hospital (Location: Fushimi-ku, Kyoto City, Director: Nagaaki Tsuda) has introduced the latest digital intraoral scanner "TRIOS 5" and the high-performance milling machine (a machine for fabricating teeth) "CEREC Primemill" to provide patients with more comfortable and precise dental treatment. By combining these two state-of-the-art devices, we achieve a "digital chairside solution" that eliminates the need for traditional putty-like material impressions and allows for speedy in-office fabrication of high-precision fillings and crowns. Background of Introduction: Reducing Patient Physical Burden with Latest Technology In dental treatment, taking impressions using putty-like materials is one of the procedures patients dislike, often accompanied by a gag reflex. By introducing the latest digital equipment, our hospital aims to significantly reduce this physical burden and provide treatment with higher precision than conventional methods. Features of Introduced Equipment Intraoral Scanner "TRIOS 5" (Manufactured by 3Shape) Less Uncomfortable Impressions: Precise 3D data is acquired simply by scanning the inside of the mouth with a small camera. No worries about discomfort or mess from traditional impression materials. High Precision and Speed: Captures 2,400 images per second, enabling the creation of precise prosthetics (fillings and crowns). Thorough Infection Control: Employs disposable sleeves and sterilizable tips for rigorous hygiene management. Dental Milling Machine "CEREC Primemill" (Manufactured by Dentsply Sirona) Extremely High Aesthetics and Fit: Uses a 0.6mm ultra-fine bur to reproduce fine grooves like natural teeth and highly accurate fits. Treatment Completion as Early as the Same Day: Since design and fabrication are completed in-house, the number of visits can be reduced, with treatment potentially completed in as little as one visit (one-visit treatment). *However, one-visit treatment will be considered private practice and will be
