中文摘要 | 利用口腔植體之支撐來製作覆蓋式義齒應用於下顎全無牙之患者,經多無來之印證,有相當高的成功率,而且大幅度改善了患者的生活品質。但過去兩階段式植牙的方式,強調3~6個月無負荷的恢復期以避免影響骨整合,但也因此延遲了患者享用正式假牙的時程,造成過渡期患者極大的不便與抱怨。 秀傳醫院牙科自民國91年7月起,開始應用早期負荷模式於下顎全無牙的患者的覆蓋式義齒的製作。方法是:手術將4支人工牙根植入患者下顎雙側頦孔之間,並當場利用事先已製好的下顎全口義齒當作印模托,印出主模型,同時取得上下顎之間關係,之後於技工室製作桿夾附連體及覆蓋式義齒,並於手術後7~14天內完成假牙的試戴。 本報告選取之病例為義齒開始負荷後超過19個月的所有個案,共有21例,共植83支人工牙根,加以追蹤評估,其中負荷後最久的為62個月,平均為41個月,在追蹤期中僅有1個個案,2支人工牙根失敗被移除,人工牙根整體存活率為97.6%(81/83),其餘所有個案,植體在X光檢查及臨床檢視下皆顯示健康、正常,義齒也都維持正常功能,患者滿意度極高。 根據本報告,應用4支人工牙根早期負荷模式的下顎全無牙患者的覆蓋式義齒,應是一種可預測且相當可靠的術式,可以在短期內就嘉惠下顎全無牙的患者,值得推廣。 |
英文摘要 | Long-term studies have documented the successful treatment of edentulous mandible with implant supported overdenture, however, a 3 to 6 months non-loading healing period is suggested in the traditional protocol, the waiting period is quite long arid the patient undergoes a lot of suffering, causing the patient to hesitate to receive such kind of treatment. This study collected 21 patients, each patient received 4 dental implants in the edentulous mandible between mental foramens, and a bar and clips type of implant supported overdenture was delivered for early loading about two weeks after implant placement. Eighty-three screw-type (67 F-2 Synchro stepped screw and 16 Xive S plus screw) implants were placed for the 21 patients, followed for a minimum of 19 months to a maximum of 62 months, with a mean follow-up of 41 months. During the follow-up, 2 implants in one patient failed, the overall survival rate was 97.6% (81/83 implants), all other implants were healthy and functioned normally in radiographic and clinical evaluation, and patients were all satisfactory over the treatment model. Results front this study demonstrated that early loading of 4 inter foraminal dental implants supporting an overenture in the completely edentulous mandible is a predictable and reliable treatment model, this model is not a sensitive technique of the dentist, and it gained high satisfaction of the patient, proving it to he a worthy recommendation. |
