中文摘要 | 中立區(neutral zone)的觀念用在全口義齒的製作上並不是一個新的方法。它主 要在強調義齒磨光面 (polishing surface) 的重要性。 希望找到一個在口內來自舌頭往外 推擠的力量,和嘴唇、臉頰往內推擠的力量互相達到中和的位置,即利用口腔周圍神經肌肉 的功能性運動來幫助義齒在口內的穩定。我們使用過去不曾被使用於中立區上的印模材料: 聚乙醚 (polyether)。病患是一位 79 歲的女性,下顎牙�レ傍Y重吸收的現象,用傳統印模 方法做出的全口義齒,不論在穩定性及固持力上都無法達到令人滿意的結果。改用中立區的 觀念重新製作一副新的義齒後,可以發現,在義齒的穩定性及固持力上都獲得了大幅度的改 善。因此我們在製作全口義齒時,不但要注意傳統方法所強調的義齒組織面及咬合面的重要 性,也不可忽略了磨光面對義齒穩定性的影響。 |
英文摘要 | The neutral zone approach to complete denture construction is neither new nor original. This technique, however, emphasizes the importance of the polishing surface of the denture and the use of the functional movement of the muscle around the mouth to stabilize the denture. The principle is to locate the area in the edentulous mouth where the forces of the tongue pressing outward are neutralized by forces of the cheeks and lips pressing inward. We used an impression material, polyehter, which had never been used in the neutral zone technique. The patient was a 79-year-old female with mandibular ridge severe resorption. Complete dentures fabricated usinig the traditional impression technique had never been satisfactory in both stability and retention. After making a new denture by applying the concept of the neutral zone, there were significant improvements in both stability and retention. Therefore, in complete denture construction, we have to pay attention to not only the traditional skills, which emphasizes the importance of tissue surface and occlusal surface of the denture, but also the stability effect of the polishing surface on the denture. |
