研究目的: |
对于非种植体平台转移的种植体,在种植体平台位置会因机械应力,钛颗粒等导致1.5-2 mm的炎症区域,导致直径1.5-2 mm的碟型吸收,当两植体距离小于3 mm时,碟状吸收区域重叠导致牙槽嵴顶降低。 假设,不仅仅是非平台转移的种植体,平台内转移的种植体也存在平台处碟型的骨吸收。在≥3 mm安全距离的情况下,相邻位点植体的高度差会导致碟型区域的重合,导致牙槽嵴顶的降低。 本研究试图分析出,在种植体水平间距3mm的前提下,相邻种植体平台垂直向间距的安全范围。 |

Objectives of Study: |
For implant-supported restorations without platform switching, mechanical stress and titanium particles can cause an inflammatory zone of 1.5-2 mm in diameter, leading to a dish-shaped absorption of the bone. When the distance between two implants is less than 3 mm, the overlapping of the dish-shaped absorption area causes a decrease in the height of the alveolar ridge. This study attempts to analyze the safe range of vertical distance between adjacent implant platforms under the premise of a horizontal spacing of 3 mm between implants, considering the possibility of dish-shaped bone absorption also occurring at the platform of implants with platform switching. |
