4 緩衝機構を有する骨内インプラント補綴装置の咬頭嵌合位における咬合接触状態(第495回大阪歯科学会例会)

抄録

We evaluated the occlusal contacts in the intercuspal position between natural teeth and prostheses that have stress absorbing elements that have been placed on osseointegrated implants. Using this information, we investigated how to best create occlusal contacts on prostheses with opposing teeth. The number and area of occlusal contacts increased with occlusal force both on the natural teeth and on the prostheses. However, the location of the contacts remained the same in both the healthy dentulous subjects and those with prostheses. We think that these results probably occur because of displacement of opposing teeth, strain on their supporting tissue and displacement of the stress absorbing elements. We concluded that a harmonious intercuspal position with natural teeth can be established by imparting appropriate occlusal contacts on the prostheses.
