摘要
目的将窄直径钛锆种植体应用于缺失后牙区,观察种植体周围软硬组织状况和可能的机械并发症,评价其临床疗效。方法选择20例接受后牙区窄直径软组织水平SLActive钛锆种植体(直径3. 3 mm)植入的患者(24颗种植体)作为观察组。另选同时期接受后牙区标准直径软组织水平SLA纯钛种植体(直径4. 1 mm)植入患者25例(30颗种植体)作为对照组。两组种植体植入后不同时间测量种植体稳定性(ISQ);完成修复并负重6个月后,记录种植体边缘骨吸收(MBL)、改良菌斑指数(m PLI)、改良龈沟出血指数(m SBI)和探诊深度(PD);同时记录可能机械并发症。结果观察组ISQ值在术后12周内保持上升趋势;对照组ISQ值4周时为低值,然后平稳上升。两组负重后6周时MBL、m PLI、m SBI和PD比较差异无统计学意义(P> 0. 05)。两组均无机械并发症发生。结论窄直径钛锆种植体应用于缺失后牙区短期内种植体周围软硬组织状况良好,可以取得较好的临床近期疗效。
Objective The small-diameter titanium-zirconium implants were used to repair the missing posterior teeth. The status of soft and hard tissue around the implants and the possible mechanical complications were observed and the clinical efficacy was evaluated. Methods 20 patients （24 implants） who were treated with small-diameter SLActive titanium-zirconium soft-tissue level implants （ diameter 3.3 ram） in the posterior teeth area were selected as observation groups. 25 patients （30 implants） were treated with standard-diameter SLA titanium soft-tissue level implants （4. 1 ram） in the posterior teeth region were selected as controls. We measured and documented the implant stability quotient （1SQ） ; 6 months after im- plant treatment, we recorded implant marginal bone loss （ MBL）, modified plaque index （ mPLI）, modified sulcus bleeding index （mSBI） and probing depth （PD） and documented the possible mechanical complications. Results The ISQ value in the observation group maintained an upward trend within 12 weeks after the operation; the ISQ value in the control group was low at 4 weeks and then increased steadily. There was no significant difference in MBL, mPLI, mSBI and PD between the two groups after six months of ending treatment. No mechanical complications occurred in either group. Conclusions Small-diameter titanium- zirconium implants repairing the missing posterior teeth have a good soft and hard organizational status and short-term clinical efficacy.
