Abstract

Objectives

Limited research is available on implant treatment outcomes in rural populations. This may be due to the presence of various barriers, such as access to oral health care, resources, health literacy, and education. The aim of this study was to evaluate the influence of patient-, site-, and implant-related factors on marginal bone levels of dental implants in a rural population in China.

Material and Methods

A retrospective study was conducted using data from a private dental office. Subjects included in this study received dental implants as part of their routine dental treatment. Information on age, gender, smoking status, diabetes, heart disease, jaw location, restorative type, loading protocol, survival rate, implant length, and diameter was collected. Marginal bone loss was recorded as the largest value at either the mesial or distal aspect on peri-apical radiographs. Descriptive and inferential statistics were performed along with linear regression analysis.

Results

Overall, 428 implants were placed in 90 subjects over an average follow-up period of 453 days. No implant failures were recorded. The average marginal bone loss was 0.10 mm, with 80.6% of implants showing no marginal bone loss. The extent of marginal bone loss was greater in the mandible (0.13 ± 0.25) than in the maxilla (0.08 ± 0.19). An increase in implant diameter by 1 mm resulted in 0.08 mm of marginal bone loss, indicating wider diameter implants are associated with more bone loss. Age was also positively correlated with marginal bone loss, increasing by 0.002 mm per year. No differences were found for gender, smoking, diabetes, heart disease, restoration type, and immediate loading.

Conclusions

Dental implant therapy in a rural Chinese population demonstrated high survival rates and minimal marginal bone loss. Factors such as age, implant location, and diameter influenced bone loss. This study fills a critical gap in understanding implant outcomes specifically within rural settings, highlighting the need for tailored approaches to enhance patient access and care in these communities. Further research is needed to explore these relationships and assess implant outcomes in rural populations.

中国农村人口种植牙边缘骨水平受患者、种植部位和种植体相关因素的影响：一项回顾性研究

目的：有关农村人口种植治疗效果的研究十分有限。这可能是由于存在各种障碍，如口腔保健、资源、健康知识和教育等。本研究的目的是评估患者、种植地和种植体相关因素对中国农村人口种植牙边缘骨水平的影响：本研究使用一家私人牙科诊所的数据进行了一项回顾性研究。研究对象在常规牙科治疗中接受了种植牙。研究收集了受试者的年龄、性别、吸烟状况、糖尿病、心脏病、颌骨位置、修复类型、加载方案、存活率、种植体长度和直径等信息。边缘骨质流失记录为根尖周X光片上中侧或远侧的最大值。研究人员进行了描述性和推论性统计，并进行了线性回归分析：90名受试者共植入了428颗种植体，平均随访时间为453天。没有种植失败的记录。平均边缘骨质流失为 0.10 毫米，80.6% 的种植体无边缘骨质流失。下颌骨的边缘骨质流失程度（0.13 ± 0.25）大于上颌骨（0.08 ± 0.19）。种植体直径增加 1 毫米会导致 0.08 毫米的边缘骨质流失，这表明直径更宽的种植体会导致更多的骨质流失。年龄也与边缘骨质流失呈正相关，每年增加 0.002 毫米。在性别、吸烟、糖尿病、心脏病、修复类型和即刻装载方面没有发现差异：结论：在中国农村人口中，种植牙治疗的存活率很高，边缘骨量损失很小。年龄、种植体位置和直径等因素都会影响骨质流失。这项研究填补了人们对农村地区种植牙治疗效果认识上的一个重要空白，强调了在这些社区提高患者就诊率和护理水平的量身定制方法的必要性。还需要进一步的研究来探索这些关系并评估农村人口的种植效果。

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.
