摘要

目的:探讨植入深度、骨型、种植体直径对短种植体初期稳定性的影响。材料和方法:不同长度的商业种植牙(6和8mm;BLX, Straumann)分别在equequal, 1mm, 2mm三个不同深度位置插入质量良好和较差的人工骨标本。植入过程中自动记录插入扭矩值。记录最大插入扭矩值(MITVs)和最终插入扭矩值(FITVs)。随后,测量所有标本的骨膜测试值(PTVs)和种植体稳定商(ISQs)。结果:各组平均mitv在31.8 ~ 46.2 Ncm之间。然而,所有组的平均fitv在8.8 - 29 Ncm之间。当植入物插入其最终位置时,扭矩值显着降低。随着插入深度的增加,PTV和ISQ降低。长种植体和植入优质骨的种植体产生了更大的初始稳定性,而骨质量似乎对初始稳定性有更大的影响。结论:当6mm短种植体在牙冠下位置植入时,初级稳定性较低,特别是在质量较差的骨中。

Effect of Implant Length and Insertion Depth on Primary Stability of Short Dental Implant.

Purpose: To evaluate the effect of insertion depth, bone type, and implant diameter on the primary stability of short implants. Materials and Methods: Commercial dental implants with different lengths (6 and 8 mm; BLX, Straumann) were inserted into artificial bone specimens of good and poor quality at three different depth positions: equicrestal, 1-mm subcrestal, and 2-mm subcrestal. Insertion torque values were recorded spontaneously during the implant procedure. Both maximum insertion torque values (MITVs) and final insertion torque values (FITVs) were recorded. Subsequently, Periotest values (PTVs) and implant stability quotients (ISQs) were measured for all specimens. Results: The mean MITVs of all groups ranged from 31.8 to 46.2 Ncm. However, the mean FITVs of all groups ranged from 8.8 to 29 Ncm. Torque values decreased significantly when the implants were inserted into their final positions. When insertion depth was increased, the PTV and ISQ decreased. Long implants and implants inserted into good-quality bone yielded greater primary stability, and bone quality appeared to have a greater effect on primary stability. Conclusion: When 6-mm short implants are inserted in a subcrestal position, low primary stability may be yielded, particularly in poor-quality bone.

期刊介绍: Edited by Steven E. Eckert, DDS, MS ISSN (Print): 0882-2786 ISSN (Online): 1942-4434 This highly regarded, often-cited journal integrates clinical and scientific data to improve methods and results of oral and maxillofacial implant therapy. It presents pioneering research, technology, clinical applications, reviews of the literature, seminal studies, emerging technology, position papers, and consensus studies, as well as the many clinical and therapeutic innovations that ensue as a result of these efforts. The editorial board is composed of recognized opinion leaders in their respective areas of expertise and reflects the international reach of the journal. Under their leadership, JOMI maintains its strong scientific integrity while expanding its influence within the field of implant dentistry. JOMI’s popular regular feature "Thematic Abstract Review" presents a review of abstracts of recently published articles on a specific topical area of interest each issue.
