背景：种植体上部结构牙冠材料的选择十分重要，其临床修复效果直接影响到种植体的寿命和患者的牙周健康状况。<br> 目的：比较Lava氧化锆全瓷、金铂合金烤瓷与银钯合金烤瓷冠在后牙单颗缺失口腔种植修复中的临床效果。方法：选择60例120颗第一磨牙缺失病例，完成单颗牙缺失种植牙修复治疗，上部结构修复牙冠材料分别为Lava氧化锆全瓷冠、金铂合金烤瓷冠与银钯合金烤瓷冠，每种材料40颗，比较3种修复体的临床修复效果。结果与结论：通过6-48个月的随访发现，Lava氧化锆全瓷冠组和金铂合金烤瓷冠组的牙龈边缘着色、龈缘密合度、修复体颜色优于银钯合金烤瓷冠组，Lava氧化锆全瓷冠组的牙龈边缘着色和修复体颜色优于金铂合金烤瓷冠组，金铂合金烤瓷冠组的龈缘密合度优于Lava氧化锆全瓷冠组；银钯合金烤瓷冠抗折程度最强，最具临床优越性，但其牙龈指数最高，牙龈健康程度最差，菌斑形成速度最快、程度最重。由此可见，在种植修复完成后需要选择较为适合的冠部修复体进行种植修复，Lava氧化锆全瓷冠具有卓越的生物相容性，而金铂合金烤瓷冠在边缘密合性方面更具优势，此两种修复体在临床治疗中具有一定的优势。
揹景：種植體上部結構牙冠材料的選擇十分重要，其臨床脩複效果直接影響到種植體的壽命和患者的牙週健康狀況。<br> 目的：比較Lava氧化鋯全瓷、金鉑閤金烤瓷與銀鈀閤金烤瓷冠在後牙單顆缺失口腔種植脩複中的臨床效果。方法：選擇60例120顆第一磨牙缺失病例，完成單顆牙缺失種植牙脩複治療，上部結構脩複牙冠材料分彆為Lava氧化鋯全瓷冠、金鉑閤金烤瓷冠與銀鈀閤金烤瓷冠，每種材料40顆，比較3種脩複體的臨床脩複效果。結果與結論：通過6-48箇月的隨訪髮現，Lava氧化鋯全瓷冠組和金鉑閤金烤瓷冠組的牙齦邊緣著色、齦緣密閤度、脩複體顏色優于銀鈀閤金烤瓷冠組，Lava氧化鋯全瓷冠組的牙齦邊緣著色和脩複體顏色優于金鉑閤金烤瓷冠組，金鉑閤金烤瓷冠組的齦緣密閤度優于Lava氧化鋯全瓷冠組；銀鈀閤金烤瓷冠抗摺程度最彊，最具臨床優越性，但其牙齦指數最高，牙齦健康程度最差，菌斑形成速度最快、程度最重。由此可見，在種植脩複完成後需要選擇較為適閤的冠部脩複體進行種植脩複，Lava氧化鋯全瓷冠具有卓越的生物相容性，而金鉑閤金烤瓷冠在邊緣密閤性方麵更具優勢，此兩種脩複體在臨床治療中具有一定的優勢。

BACKGROUND:Studies have shown that selection of implant crowns that directly impact the service life of implants and patient’s periodontal health is very important. <br> OBJECTIVE:To compare the clinical effects of Lava zirconia crowns, goal-platinum al oy ceramic crowns and silver-pal adium al oy crowns supplemented by dental implants used in the single missing posterior tooth. <br> METHODS:Sixty patients with first molar missing (120 teeth) were divided into three groups and treated with Lava zirconia, goal-platinum al oy ceramic and silver-pal adium al oy crowns applied to the dental implants for posterior column defects. The clinical restorative effects of three prostheses were compared. <br> RESULTS AND CONCLUSION:During 6-48 months of fol ow-up, the gingival edge coloring, gingival margin microleakage, the color of prosthesis of Lava zirconia al oy ceramic crowns and gold-platinum al oy ceramic crowns were better than those of silver-pal adium al oy crowns, and the gingival edge coloring and the color of prosthesis of Lava zirconia al oy ceramic crowns were better than those of gold-platinum al oy ceramic crowns, while the gingival margin microleakage of gold-platinum al oy ceramic crowns was better than that of Lava zirconia al oy ceramic crowns. Silver-pal adium al oy crowns were lower than Lava zirconia ceramic crowns and gold-platinum al oy ceramic crowns in the fracture extent. But silver-pal adium al oy crowns had the highest gingival index, the worst gingival health and rapidest and most severe plaque formation. Therefore, Lava zirconia al-ceramic crowns and gold platinum al oy-porcelain crown are ideal prostheses for implant restorations. The former has better biocompatibility, and the latter shows better marginal adaptation.
