摘要

As dental implant treatment has become more widespread, it is now regarded as a common treatment method for addressing tooth loss. Since dental implants are placed into the extracted alveolar bone, the condition of the alveolar bone and the amount of available bone determine the difficulty of the procedure. Securing sufficient hard tissue around the implant mainly influences its long-term stability. The condition of the residual alveolar ridge varies among patients depending on the cause of extraction and the time elapsed before implant placement. Placing implants in severely resorbed alveolar bone and creating new bone is generally very challenging, requires a long treatment period, and demands careful selection of graft materials and barrier membranes. In this lecture, we will discuss considerations for hard tissue reconstruction in patients with moderate to severe horizontal and vertical bone defects, surgical precautions, and methods to simplify complex and difficult procedures.

摘要

In Japan, oral hypofunction in older adults and oral function developmental disorder in children were officially established as diagnostic categories covered by the public health insurance system in 2018. In addition, the Ministry of Health, Labour and Welfare has clearly emphasized that the role of the family dentist extends beyond the management of dental caries and periodontal disease to include the acquisition, maintenance, and restoration of oral function. As a result, the importance of oral function management has gained increasing attention.

Assessment of oral hypofunction is conducted using seven examination items: poor oral hygiene, oral dryness, decreased occlusal force, reduced tongue–lip motor function, low tongue pressure, impaired masticatory function, and impaired swallowing function. Individuals who meet three or more of these criteria are diagnosed with oral hypofunction and are managed through comprehensive oral function management. However, unlike diseases such as dental caries and periodontal disease, which are associated with visible structural changes, oral function represents an intrinsic and functional condition. Consequently, many dental professionals find it challenging to form a concrete clinical image of oral function management.

In this lecture, methods for assessing oral function in older adults, interpretation of assessment results, and practical approaches to oral function management will be explained. Actual clinical cases will also be presented to illustrate real-world application.
