Abstract

Objective: To evaluate the clinical efficacy of clear aligner therapy in patients with severe periodontitis accompanied by pathological tooth displacement in the anterior region.

Methods: This retrospective study analyzed patients diagnosed with severe periodontitis and pathological displacement in the anterior region, who visited both the Periodontics and Orthodontics Departments at Peking University School and Hospital of Stomatology between 2019 and 2022. A total of 26 eligible cases were included in this study. All the patients underwent regular periodontal maintenance throughout the treatment process, and clear aligners were used for orthodontic treatment. Intraoral scans were analyzed by dedicated software to measure and compare occlusal distribution and proximal contact scores before and after orthodontic treatment. Periodontal clinical indicators were assessed at three key time points: before periodontal treatment (T0), before orthodontic treatment (T1), and after orthodontic treatment (T2). All the cases were treated with clear aligner.

Results: A total of 217 pathologically displaced anterior teeth from 26 patients were analyzed. Among these, 105 teeth exhibited periodontal pockets [probing depth (PD) ≥5 mm] before periodontal treatment. After clear aligner therapy, the occlusal score improved significantly from 10.35±8.61 to 23.62±9.73 (P < 0.001), and the proximal contact score increased from 13.62±4.73 to 31.62±10.37 (P < 0.001). The median PD decreased significantly from 3.33 mm [interquartile range (IQR)=0.92] at T0 to 2.50 mm (IQR=0.67, P < 0.001) at T1 and remained stable at 2.50 mm (IQR=0.50) after treatment (T2). A significant reduction in PD was observed between T0 and T2 (P < 0.001), but no significant difference was found between T1 and T2 (P=0.948).

Conclusion: Clear aligner therapy demonstrates favorable clinical efficacy in patients with severe periodontitis and pathological anterior tooth displacement. It effectively improves occlusal distribution and proximal contact while maintaining periodontal health in these patients. However, further large-scale prospective controlled studies are needed to verify its long-term clinical outcomes.

目的：评估透明矫治器治疗伴有前牙病理性移位的严重牙周炎患者的临床疗效：评估透明矫治器治疗伴有前牙病理性移位的重度牙周炎患者的临床疗效：本回顾性研究分析了2019年至2022年期间在北京大学口腔医学院附属北京大学口腔医院牙周科和正畸科就诊的确诊为重度牙周炎并伴有前牙病理性移位的患者。本研究共纳入了 26 例符合条件的病例。在整个治疗过程中，所有患者都定期进行牙周维护，并使用透明矫治器进行正畸治疗。口内扫描通过专用软件进行分析，测量并比较正畸治疗前后的咬合分布和近端接触评分。牙周临床指标在三个关键时间点进行评估：牙周治疗前（T0）、正畸治疗前（T1）和正畸治疗后（T2）。所有病例均采用透明矫治器进行治疗：结果：共分析了 26 名患者的 217 颗病理性移位前牙。其中，105 颗牙齿在牙周治疗前有牙周袋[探诊深度（PD）≥5 毫米]。经过透明矫治器治疗后，咬合评分从（10.35±8.61）分明显提高到（23.62±9.73）分（P＜0.001），近端接触评分从（13.62±4.73）分提高到（31.62±10.37）分（P＜0.001）。中位PD从T0时的3.33 mm [四分位距（IQR）=0.92]明显降低到T1时的2.50 mm (IQR=0.67, P < 0.001)，治疗后（T2）稳定在2.50 mm (IQR=0.50)。在T0和T2之间观察到PD明显减少（P<0.001），但在T1和T2之间没有发现明显差异（P=0.948）：结论：透明矫治器疗法对严重牙周炎和病理性前牙移位患者具有良好的临床疗效。结论：透明矫治器疗法对严重牙周炎和病理性前牙移位患者有良好的临床疗效，它能有效改善咬合分布和近端接触，同时保持这些患者的牙周健康。不过，还需要进一步的大规模前瞻性对照研究来验证其长期临床疗效。

The coverage of the Journal includes basic medical sciences, clinical medicine, oral medicine, surgery, public health and epidemiology, pharmacology and pharmacy. Over the last few years, the Journal has published articles and reports covering major topics in the different special issues (e.g. research on disease genome, theory of drug withdrawal, mechanism and prevention of cardiovascular and cerebrovascular diseases, stomatology, orthopaedic, public health, urology and reproductive medicine). All the topics involve latest advances in medical sciences, hot topics in specific specialties, and prevention and treatment of major diseases. The Journal has been indexed and abstracted by PubMed Central (PMC), MEDLINE/PubMed, EBSCO, Embase, Scopus, Chemical Abstracts (CA), Western Pacific Region Index Medicus (WPR), JSTChina, and almost all the Chinese sciences and technical index systems, including Chinese Science and Technology Paper Citation Database (CSTPCD), Chinese Science Citation Database (CSCD), China BioMedical Bibliographic Database (CBM), CMCI, Chinese Biological Abstracts, China National Academic Magazine Data-Base (CNKI), Wanfang Data (ChinaInfo), etc.
