Abstract

Objectives

This case series evaluates healing parameters of immediately placed implants in fresh extraction sockets without osteotomies. It examines resonance frequency analysis (RFA) trends and radiographic bone changes from placement to prosthetic restoration.

Material and Methods

The study reports on eight patients with 10 implants using a self-tapping, knife-shaped implant with progressive thread design and anatomical healing abutments. RFA values and standardized radiographs were recorded at three time points from placement to prosthetic restoration.

Results

Implants were placed in molar, premolar, and incisor sockets. All implants achieved insertion torque greater than 35 Ncm and high ISQ values. The median reported bone remodeling was 0.35 mm from implant placement to definitive restoration. RFA revealed a median of 64 ISQ buccolingually and 74 ISQ mesiodistally at placement, increasing to 76 ISQ buccolingually and 82 ISQ mesiodistally pre-prosthetically.

Conclusions

The findings suggest that immediate dental implants placed without osteotomies in select anatomical conditions can achieve successful osseointegration and functional stability. However, given the small sample size, further studies with larger cohorts are necessary to validate these results.

牙种植体放置在新鲜的人类拔牙槽而不截骨：一个案例系列

目的：评价即刻种植体在不截骨的情况下在新鲜拔牙槽内的愈合参数。它检查了共振频率分析（RFA）趋势和放射学骨变化从放置到假体修复。材料与方法8例患者共10颗种植体，采用自攻式刀形种植体，采用进进式螺纹设计和解剖式愈合基台。从放置到假体修复的三个时间点记录RFA值和标准化x线片。结果种植体放置于磨牙、前磨牙和切牙槽内。所有植入物的插入扭矩均大于35 Ncm， ISQ值较高。从种植体植入到最终修复，骨重塑的中位数为0.35 mm。RFA显示，安置后的中位ISQ为上腭64，中位ISQ为中位74，假体前的中位ISQ为上腭76，中位ISQ为中位82。结论在一定的解剖条件下，不进行截骨术的即刻种植体可以获得良好的骨整合和功能稳定性。然而，由于样本量小，需要进一步研究更大的队列来验证这些结果。

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
