The aim of the present study was to evaluate retrospectively the clinical and radiographic behaviour of four commercially-available short implants with different macrodesigns and microdesigns in areas in which the height of the bone was reduced. We took into account the success and survival, peri-implant crestal bone loss, and the level of probing at which the gum bled. Patients were included if they had been given one or more short implants (≤8.5mm long) in the posterior jaws at least three years earlier. Three hundred and ninety-one short implants were placed in 170 subjects, and were divided in four groups based on the brand of implant. The implants were evaluated one, two, and three years after they had been inserted. Short implants had a three-year survival and success rate of 90% in all groups, and bone loss was acceptable after three years with no significant differences between them. These results support the use of short implants as an effective and safe treatment. However, within the limitations of this study, the design of the implant does seem to influence the behaviour of peri-implant bone at the crestal level.
本研究的目的是回顾性评估四种具有不同宏观设计和微观设计的市售短种植体在骨高度降低区域的临床和影像学表现。我们考虑了种植体的成功率和存活率、种植体周围嵴顶骨吸收情况以及牙龈出血时的探诊深度。如果患者至少在三年前于后牙区植入了一个或多个短种植体（长度≤8.5mm），则将其纳入研究。170名受试者共植入了391颗短种植体，并根据种植体品牌分为四组。在种植体植入后1年、2年和3年对其进行评估。所有组的短种植体三年存活率和成功率均为90%，三年后骨吸收情况可接受，且各组之间无显著差异。这些结果支持将短种植体作为一种有效且安全的治疗方法。然而，在本研究的局限性内，种植体的设计似乎确实会影响嵴顶水平种植体周围骨的表现。
