BACKGROUND 背景
 
Immediate loading of single implants is generally considered a reliable procedure.
立即承載的單顆植牙通常被認為是可靠的過程。
 
PURPOSE 目的
 
The objective of the present prospective randomized clinical study was to compare the overall treatment outcome following immediate loading (IL) and delayed loading (DL) of single implants after 1 year of follow-up.
本前瞻性隨機臨床研究目的是追蹤一年後立即承載(IL)和延遲承載(DL)的單顆植牙的整體治療結果比較。
 
MATERIALS AND METHODS 材料和方法
 
Patients with a missing maxillary tooth (15-25) were randomly assigned to IL or DL. The protocol included implant installation in healed sites,immediate loading, delayed loading, temporary screw-retained restoration, and replacement with a permanent single implant crown. Outcome measures were implant survival, marginal bone level, soft tissue changes, papillae index, pink, and white esthetic score (PES and WES), patient judged aesthetics, and oral health impact profile (OHiP-14).;
將上顎缺牙(齒位15-25)的病患隨機分配立即承載(IL)和延遲承載(DL)的植入方式。這項協議包括在癒合部位植入植體，立即承載，延遲承載，螺紋固定的臨時贗復，以及使用永久性單一牙冠。結果測量包括植體存活率、邊緣骨水平、軟組織變化、乳突指數、粉紅色和白色的美學分數(PES和WES)，判斷患者的美學和口腔健康影響狀況(OHiP-14)。
 
RESULTS 結果
 
Implant survival rate was 100% and 96% for IL and DL, respectively. Implant success rate was 96% and 88% for IL and DL, respectively. Statistically significant lower papilla index scores were found in the IL group at temporary crown and definitive crown placement. An overall statistically significant improvement after 12 months for PES, WES and OHIP-14 was found.
立即承載(IL)和延遲承載(DL)的植體存活率分別為100%和96%。立即承載(IL)和延遲承載(DL)的植體成功率分別為96%和88%。立即承載(IL)組在臨時牙冠和最終牙冠部位中可發現統計學在較低的乳突指數評分中具有顯著的意義。在整體的統計學發現粉紅色和白色的美學分數(PES和WES)，與口腔健康影響狀況(OHiP-14)在12個月後具有顯著的的改善。
 
CONCLUSIONS 結論
 
This prospective randomized study showed that single implants in the maxilla can present satisfactory results with respect to either immediate loading or delayed loading after 12 months.
這項前瞻性隨機研究顯示，上顎骨植入單一植體在12個月後在立即承載或延遲承載兩者間皆可獲得滿意的結果。
