Located in Matsuyama City, Ehime Prefecture, Ohisama Dental Clinic offers implant treatment based on extensive experience and advanced techniques cultivated in the oral surgery department of university hospitals. The clinic handles difficult cases that other clinics may struggle with, including bone augmentation for cases with insufficient bone and All-on-4, where all teeth are replaced with implants. They prioritize safety in their treatment planning based on detailed examinations and diagnoses using preoperative CT scans. To enhance surgical safety and precision, they use CT scans to three-dimensionally understand bone morphology and nerve locations beforehand, perform detailed implant simulation on the computer, and use a surgical guide device for all cases. In addition to these digital technologies, the clinic offers orthodontic treatment using transparent and discreet aligner-type devices, thanks to the ability to obtain precise dental impressions simply by scanning the mouth with an intraoral scanner. In terms of treatment, the clinic focuses on precise root canal treatment, examining the inside of complex root canals in detail while magnifying the field of view to over 20 times using a microscope. In terms of facilities, they have a thorough sterilization system using Class B sterilizers that meet the world's strictest standards. Furthermore, they have established an in-house digital dental treatment system that integrates intraoral scanners, design software, and ceramic fabrication machines, allowing for the creation of precise ceramic fillings and crowns without needing to outsource to dental laboratories. Patients are shown images from intraoral cameras and microscopes while treatment content and oral conditions are explained in an easy-to-understand manner, enabling visual confirmation of before-and-after comparisons. In addition to these initiatives, the clinic features barrier-free accessibility, accepts credit cards and electronic payments, and provides on-site parking.
