ObjectiveTo compare fully guided flapless implant surgery using a light‐cured surgical guide (FG group) with partially guided open flap surgery (PG group) in the posterior maxilla when performing simultaneous sinus floor elevation in terms of the accuracy, time requirements, and patient/clinician‐reported outcomes (PROMs and CROMs).Materials and MethodsIn this study, 56 tissue‐level implants were placed with crestal sinus floor elevation in 56 patients at single‐tooth sites, with 28 implants allocated to the PG group and 28 to the FG group. The deviations of the placed implants from the virtually planned positions were measured at the implant platform and apex and for the angular deviation. The presurgical preparation time and the duration of surgery were measured. PROMs and CROMs were made by administering questionnaires at multiple time points.ResultsHorizontal deviations at the platform and apex and the angular deviation were significantly smaller in the FG group than the PG group (p < .05). Presurgical preparation and surgery times were significantly shorter in the FG group (p < .001). Patient satisfaction and willingness to receive repeat treatment were significantly better in the FG group than in the PG group (p < .005 and .025, respectively). Clinicians were more satisfied in the FG group than the PG group (p < .05).ConclusionWhen placing an implant with sinus floor elevation, the flapless approach using a fully guided surgical system can be more accurate, faster, and increase the satisfaction of both the clinician and patient compared to the partially guided surgery.

关于定制、完全引导种植体系统用于无翻瓣牙槽嵴窦底抬高功效的随机对照试验：准确性和患者报告的结果


目的比较光固化手术导板全引导无翻瓣种植手术（FG组）与上颌后部部分引导开瓣手术（PG组）同步上颌窦底抬高的准确性、时间要求和患者/患者情况。临床医生报告的结果（PROM 和 CROM）。 材料和方法在这项研究中，56 名患者的单牙部位植入了 56 颗组织水平种植体，牙槽嵴窦底抬高，其中 28 颗种植体分配给 PG 组，28 颗种植体分配给 FG 组团体。在种植体平台和根尖处测量所放置的种植体与实际计划位置的偏差以及角度偏差。测量术前准备时间和手术持续时间。通过在多个时间点进行问卷调查来制作PROM和CROM。结果FG组的平台和顶点的水平偏差以及角度偏差显着小于PG组（ p < .05)。 FG 组的术前准备和手术时间显着缩短（ p < .001)。 FG 组的患者满意度和接受重复治疗的意愿明显好于 PG 组（ p分别 < .005 和 .025）。临床医生对 FG 组比 PG 组更满意（ p < .05).结论当放置上颌窦底抬高种植体时，与部分引导手术相比，使用完全引导手术系统的无瓣入路可以更准确、更快速，并提高临床医生和患者的满意度。
