Maxillary Complete Denture and Mandibular Overdenture on Two Implants with Universal Design
A 78-year-old female patient was referred by the Department of Neurosurgery to the Department of Biomaterials and Prosthodontics of Kyung Hee University Dental Hospital, Gangdong, Seoul, South Korea. The patient was suffering from facial nerve palsy due to an ischemic stroke that had left parts of her eye, chin, lip, tongue, and extremity paralyzed. She had been wearing maxillary and mandibular complete dentures for 10 years, but after the stroke they were not suitable anymore as her mandibular denture became dislodged during function. In our aging society, dentures for the disabled and elderly are crucial in terms of patient satisfaction and health-related quality of life. Patients suffer from chronic and severe disorders, and elderly/disabled patients need special dental care. The provision of dentures using a minimally invasive treatment approach and a universal design are important issues (Leesungbok 2004).

* General SAC assessment modifiers that are also part of the ERA. To avoid redundancy they are listed in this section even if no complete ERA has been made.
** Not applicable to the ERA of immediate placement cases and replaced by "Socket Integrity" listed below under "Surgical SAC Classification". For all other placement types this value is a classification determinant and listed here even if no complete ERA has been made.
