| 目的探讨种植术后前牙区唇侧骨板厚度对种植体颈部牙槽骨吸收的影响。方法选取上颌前牙缺失患者102例,根据术前唇侧骨板厚度分为≤1 mm组和1~2 mm组各51例。比较两组咬合、感染、骨吸收、角化龈宽度(KGW)及牙周状况。 结果≤1 mm组垂直骨吸收高于1~2 mm组,水平骨吸收低于1~2 mm组(P＜0.05)。T3、T4时,≤1 mm组KGW均小于1~2 mm组(P＜0.05)。与T0时比较,T4时两组牙菌斑指数、牙龈指数和龈沟出血指数均明显降低,且1~2 mm组改善更明显(P＜0.05)。与T3时比较,T4时≤1 mm组红色美学指数(PES)、白色美学指数(WES)减小(P＜0.05)。T4时≤1 mm组PES、WES低于1~2 mm组(P＜0.05)。 结论唇侧骨板厚度1~2 mm时,表现出更轻微的垂直骨吸收、更宽的KGW及更理想的牙周状况和美学效果,但水平骨吸收较≤1 mm时更大。 |

| AimTo investigate the effects of labial bone thickness on alveolar bone resorption at the neck of implants in the anterior region after implantation. MethodsA total of 102 patients with missing maxillary anterior teeth were selected and divided into two groups based on preoperative labial bone thickness, namely the ≤1 mm group (n＝51) and the 1~2 mm group (n＝51). Occlusion, infection, bone resorption, keratinized gingival width (KGW), and periodontal status were compared between the two groups. ResultsThe vertical bone resorption in the ≤1 mm group was higher than that in the 1~2 mm group, while the horizontal bone resorption was lower (P＜0.05). At T3 and T4, the KGW in the ≤1 mm group was significantly smaller than that in the 1~2 mm group (P＜0.05). Compared to T0, both groups showed significant reductions in plaque index (PI), gingival index (GI), and sulcus bleeding index (SBI) at T4, with greater improvement in the 1~2 mm group (P＜0.05). Compared to T3, the pink esthetic score (PES) and white esthetic score (WES) in the ≤1 mm group decreased at T4 (P＜0.05). At T4, the PES and WES in the ≤1 mm group were lower than those in the 1~2 mm group (P＜0.05). ConclusionWhen the labial bone thickness is 1~ 2 mm, it exhibits less vertical bone resorption, a wider KGW, and more ideal periodontal conditions and aesthetic outcomes. However, the horizontal bone resorption is greater compared to when the thickness is ≤1 mm. |
