To compare intra- and postoperative outcomes between the standard linear incision technique with tissue preservation (LITT-P) and the minimally invasive star-shaped incision (SSI).
A retrospective cohort study.
Primary outcomes evaluated operative time, implant survival, and intra-operative complications. A secondary outcome evaluated soft tissue tolerability assessed by the Holger's classification.
A total of 38 implants were placed (19 LITT-P; 19 SSI). The median and mean surgical duration for the LITT-P group was statistically shorter than the SSI group ( = 0.0001). No intra-operative complications were reported for both surgical approaches. Five implants were lost during postoperative follow-up: one in the LITT-P and four in the SSI cohort. Both cohorts showed favorable soft tissue tolerability. Less Holgers 1 and 2 and more Holgers 3 soft tissue reactions were observed after the LITT-P compared to the SSI.
The novel SSI approach could be an alternative option based on the theoretical benefits and found favorable (and similar) soft tissue outcomes. Implant loss and surgical time are aspects to investigate regarding long-term durability and warrant further research.
比较标准线性切口组织保留技术（LITT-P）和微创星形切口（SSI）的术中和术后结果。
一项回顾性队列研究。
主要结局评估手术时间、种植体存活率和术中并发症。次要结局评估通过霍尔格分类法评估的软组织耐受性。
共植入38枚种植体（19枚LITT-P；19枚SSI）。LITT-P组的中位手术时间和平均手术时间在统计学上短于SSI组（P = 0.0001）。两种手术方法均未报告术中并发症。术后随访期间有5枚种植体丢失：LITT-P组1枚，SSI组4枚。两组均显示出良好的软组织耐受性。与SSI相比，LITT-P术后观察到的霍尔格1级和2级软组织反应较少，霍尔格3级软组织反应较多。
基于理论优势，新型SSI方法可能是一种替代选择，并发现其软组织结局良好（且相似）。种植体丢失和手术时间是关于长期耐久性需要研究的方面，值得进一步研究。
