嚴重磨耗牙齒補綴治療之病例

臨床上造成牙齒嚴重磨耗的原因有很多，這也是牙醫在治療上的一大困擾。本病例討論對於因磨牙與後牙喪失而造成之嚴重磨耗齒列，以雙重冠義齒的治療方式提高咬合高度並恢復齒列外觀。雖然此種設計之固持力不如精密附著裝置或雙重冠，但是病患對於美觀、咬合與咀嚼功能上的滿意度尚佳。在牙科膺復治療後，於六個月之定期回診時，發現病患之牙周狀況良好，也未有顳顎關節或冗肉方面的症狀出現，表示當初所提高的咬合高度是在其可接受的範圍以內。因此以雙重冠義齒做為牙齒嚴重磨耗病患之膺復治療方式是可行的。

Though this design was less retentive force than precision attachment of Konus denture, the patient was satisfactory with the cosmetic, occlusal, and masticatory considerations. After the full mouth rehabilitation, the periodontal status, TMJ and muscle condition of the patient were good in periodic recall, and this indicated that the height of initial bite rising was acceptable by the patient. So, the prosthodontic treatment for severe attritted dentition with non-retentive telescopic denture was suggested.
