Abstract

Background/purpose

Although reimplantation is currently a common treatment procedure, little information on reimplantation success or failure is available in the literature. The purpose of the present investigation was to evaluate the survival rate of dental implants that were performed in sites of previously failed implants and identify factors associated with the treatment outcome.

Materials and methods

This retrospective study is based on a cohort of patients rehabilitated with dental implants in the dental clinics of the universities contributing data to the BigMouth network between 2011 and 2022. Implants replacing a previously failed implant at the same site were included. Cases of first and second reimplantations were included Information regarding patients' characteristics including age, gender, ethnicity, race, tobacco use, and systemic medical conditions were extracted from patients’ files.

Results

Records of 50,333 dental implants placed in 20,842 patients over a 12-year period were screened. Three hundred seventy implants placed in 284 patients were replaced by another implant at the same site. The cumulative survival rates of implants inserted for the first time was 98.6 %, for the first replacements was 96.1 % and for the second replacements was 91.7 %. First reimplants exhibited a significantly higher risk of failure than initial implantation (P < 0.001). Similarly, second reimplants demonstrated significantly greater risk of failure (P = 0.05) when compared to initial implants. No significant associations were detected between replaced implant failures with any of the patient related parameters evaluated (P > 0.05).

Conclusion

Within the limitations of the present study, dental implants replacing failed implants exhibited lower survival rates than the rates reported for the previous attempts of implant placement. No risk indicators for implant failure were identified. Additional factors should be examined in future studies.

在以前失败的植入部位进行植入手术的存活率以及与失败相关的因素:回顾性调查
背景/目的虽然再植牙目前是一种常见的治疗方法,但有关再植成功或失败的文献资料却很少。材料和方法这项回顾性研究基于 2011 年至 2022 年间向 BigMouth 网络提供数据的大学牙科诊所中接受牙科种植修复的患者队列。研究对象包括在同一部位替换先前失败种植体的患者。从患者档案中提取了有关患者特征的信息,包括年龄、性别、民族、种族、吸烟情况和全身性疾病。284名患者的370颗种植体被同一部位的另一颗种植体取代。首次植入的种植体的累积存活率为 98.6%,首次替换的种植体的累积存活率为 96.1%,第二次替换的种植体的累积存活率为 91.7%。首次再次植入的失败风险明显高于首次植入(P < 0.001)。同样,与初次植入相比,第二次再植入的失败风险明显更高(P = 0.05)。结论在本研究的限制条件下,替代失败种植体的牙科种植体的存活率低于前几次种植尝试的存活率。本研究未发现种植失败的风险指标。在今后的研究中还应研究其他因素。

期刊介绍: he Journal of Dental Sciences (JDS), published quarterly, is the official and open access publication of the Association for Dental Sciences of the Republic of China (ADS-ROC). The precedent journal of the JDS is the Chinese Dental Journal (CDJ) which had already been covered by MEDLINE in 1988. As the CDJ continued to prove its importance in the region, the ADS-ROC decided to move to the international community by publishing an English journal. Hence, the birth of the JDS in 2006. The JDS is indexed in the SCI Expanded since 2008. It is also indexed in Scopus, and EMCare, ScienceDirect, SIIC Data Bases. The topics covered by the JDS include all fields of basic and clinical dentistry. Some manuscripts focusing on the study of certain endemic diseases such as dental caries and periodontal diseases in particular regions of any country as well as oral pre-cancers, oral cancers, and oral submucous fibrosis related to betel nut chewing habit are also considered for publication. Besides, the JDS also publishes articles about the efficacy of a new treatment modality on oral verrucous hyperplasia or early oral squamous cell carcinoma.
