There is a paucity of studies that assess short and narrow dental implants. This prospective study aimed to evaluate the performance of both short (≤8 mm) and narrow (≤3.5 mm width) dental implants supporting fixed prostheses in the atrophic maxilla or mandible. Towards that aim, patients with short implants were included in the study. The control group was those with long and narrow dental implants (length > 8 mm and diameter ≤ 3.5 mm). Clinical and demographic variables were extracted from clinical records. During the follow-up, implant survival and marginal bone loss were evaluated and statistically analysed. Forty-one implants were included (18 and 23 implants in the test and control groups, respectively). The median follow-up time was 26 months since insertion in both groups. The results revealed that there was no implant failure and no statistically significant differences in terms of marginal bone loss. Only one screw-loosening effect occurred in the short implants group. Short, narrow dental implants could be an alternative for the restoration of severely resorbed jaws.
评估短而窄的牙科种植体的研究较少。这项前瞻性研究旨在评估短（≤8毫米）和窄（宽度≤3.5毫米）的牙科种植体在萎缩性上颌骨或下颌骨中支持固定修复体的性能。为实现该目标，短种植体患者被纳入研究。对照组为长而窄的牙科种植体患者（长度>8毫米且直径≤3.5毫米）。从临床记录中提取临床和人口统计学变量。在随访期间，评估种植体存活率和边缘骨丢失情况并进行统计学分析。共纳入41枚种植体（试验组和对照组分别为18枚和23枚）。两组植入后的中位随访时间均为26个月。结果显示，没有种植体失败，边缘骨丢失方面也没有统计学上的显著差异。短种植体组仅发生1例螺钉松动情况。短而窄的牙科种植体可作为严重吸收性颌骨修复的一种替代方案。
