摘要

目的本研究旨在评估一次性基台植入方案（试验组）与在修复阶段断开并连接三次愈合基台后在功能负荷日植入最终基台（对照组）对临床和放射学结果的影响：40名患者共80颗种植体被随机分配到试验组或对照组。在功能负荷 6 个月和 12 个月后，评估并比较放射学边缘骨水平 (MBL)、临床结果、修复相关结果和患者报告结果测量 (PROM) 的变化：对 37 名患者的 74 个种植体进行了为期 12 个月的随访。两组患者在植入种植体后都观察到了具有统计学意义的骨重塑。对照组在 6 个月（-0.13 mm 对 -0.61 mm）和 12 个月（-0.01 mm 对 -0.53 mm）时的 MBL 明显更大。对照组从手术到 6 个月和 12 个月以及从加载到 6 个月和 12 个月的骨质流失明显更多。测试组的基台高度明显更高，但修复角度没有明显差异。同样，在测量的临床变量（探诊深度、牙菌斑和出血指数）和PROMs方面，组间也没有明显的统计学差异：结论：与在种植体安装时植入最终基台相比，断开并重新连接愈合基台与12个月后骨质流失显著增加有关。

Effect of one-time placement of the definitive abutment versus multiple healing abutment disconnections and reconnections during the prosthetic phase on radiographic and clinical outcomes: A 12-month randomized clinical trial

Objective

The aim of this investigation was to evaluate the effect on clinical and radiological outcomes of the one-abutment, one-time protocol (test) versus placing the definitive abutment on the day of functional loading after having disconnected and connected three times the healing abutment during the prosthetic phase (control).

Materials and methods

Forty patients with 80 implants were randomly allocated to either the test or the control group. Changes in the radiographic marginal bone levels (MBLs), clinical outcomes, prosthetic-related outcomes, and patient-reported outcomes measures (PROMs) were assessed and compared 6 and 12 months after functional loading.

Results

Thirty-seven patients with 74 implants were followed at 12 months. A statistically significant bone remodeling was observed in both groups following implant placement. MBLs were significantly greater in the control group at the 6- (−0.13 mm vs. −0.61 mm) and 12-month visits (−0.01 mm vs. −0.53 mm). Bone loss was significantly greater in the control group from surgery to 6 and 12 months and from loading to 6 and 12 months. The abutment height was significantly greater in the test group, however, there were no significant differences in the restorative angle. Similarly, there were no statistically significant differences between groups for the measured clinical variables (probing depth, plaque, and bleeding index) and PROMs.

Conclusions

Disconnecting and reconnecting the healing abutment was associated with significantly higher bone loss after 12 months, as compared to the placement of the definitive abutment at implant installation.

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
