Introduction

The impact of NSAIDs on osseointegration remains controversial, with conflicting evidence from animal models and human clinical trials. The aim of the study was to investigate the association between the use of common Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) and the risk of early dental implant failure in a large, real-world patient cohort.

Methods

This retrospective cohort study utilized an EHR database of 12,943 patients receiving 49,997 implants. Patients were divided into an NSAID group (n = 3133) and a non-NSAID control group (n = 9810). The primary outcome was early implant failure, defined as implant removal within six months of placement. Multivariable logistic regression models were used to calculate Odds Ratios (ORs) for failure, adjusting for patient age, gender, history of diabetes, and history of osteoporosis. Analyses were conducted at both the implant and patient levels.

Results

Patients in the NSAID group were significantly older (62.8 vs. 58.7 years, p < 0.0001) and had a higher prevalence of diabetes (22.0% vs. 16.7 %, p < 0.0001) and osteoporosis (11.0 % vs. 7.0 %, p < 0.0001). After adjusting for confounders, implant-level analysis showed that Ibuprofen use (OR 2.29; 95 % CI 1.48–3.55; p < 0.0001) and Naproxen use (OR 2.65; 95 % CI 1.22–5.75; p = 0.0137) were significantly associated with increased odds of early failure. At the patient level, the association remained highly significant for Ibuprofen (OR 2.87; 95 % CI 1.83–4.51; p < 0.0001), but not for Naproxen (p = 0.0689).

Conclusion

The use of Ibuprofen and, to a lesser extent, Naproxen, is associated with a significantly increased risk of early dental implant failure, independent of other patient risk factors. Clinicians should consider these findings when formulating post-operative analgesic plans, particularly for patients with complex medical histories.
非甾体抗炎药对骨整合的影响仍然存在争议,动物模型和人体临床试验的证据相互矛盾。该研究的目的是在一个庞大的现实世界患者队列中调查常用非甾体抗炎药(NSAIDs)的使用与早期种植体失败风险之间的关系。方法:本回顾性队列研究利用了12943例植入物患者的EHR数据库。患者被分为非甾体抗炎药组(n= 3133)和非甾体抗炎药对照组(n= 9810)。主要结局是早期种植体失败,定义为种植体在放置6个月内移除。使用多变量logistic回归模型计算失败的优势比(ORs),调整患者的年龄、性别、糖尿病史和骨质疏松史。在种植体和患者水平上进行分析。结果:非甾体抗炎药组患者的年龄明显增加(62.8岁vs. 58.7岁)。结论:使用布洛芬和(在较小程度上)使用萘普生与早期种植体失败的风险显著增加相关,独立于其他患者危险因素。临床医生在制定术后镇痛计划时应考虑这些发现,特别是对于有复杂病史的患者。

Objective

To investigate vascular endothelial growth factor (VEGF) mRNA expression as an independent biomarker for predicting recurrence in ameloblastoma (AM), and to evaluate its potential for guiding surgical strategy.

Methods

A retrospective cohort study was conducted involving 200 patients with primary AM undergoing initial surgery during January 2021-December 2023. Patients were categorized into curettage (n = 77) and extended resection (n = 123) groups. Relative VEGF mRNA expression in the tumor cyst wall was quantified using RT-qPCR. Kaplan-Meier analysis and Cox regression were used to analyze recurrence-free survival (RFS) and risk factors. Perioperative outcomes and complications were compared between groups. Univariate and multivariate analyses were performed using Cox proportional hazards regression models.

Results

VEGF mRNA expression was significantly elevated in the recurrence group (4.66 ± 1.42) versus the non-recurrence group (3.24 ± 2.02, P < 0.001). ROC curve analysis identified an optimal VEGF cutoff value of 4.88 for predicting recurrence (AUC = 0.694). This molecular stratification revealed a profound disparity: the 2-year RFS was significantly lower in the VEGF-high group (77.4 %) compared to the VEGF-low group (94.9 %, P < 0.001). While extended resection provided a higher 2-year RFS than curettage (96.0 % vs. 79.5 %, P < 0.001), it incurred greater operative burden and complication risks. Crucially, multivariate analysis established high VEGF expression as the most powerful independent predictor of recurrence (HR = 45.15, P < 0.001), with a risk magnitude exceeding that of curettage (HR = 37.22, P < 0.001).

Conclusion

High VEGF mRNA expression is a powerful, independent biomarker for AM recurrence, with a prognostic impact surpassing surgical choice. Preoperative VEGF assessment holds significant potential for guiding individualized surgical planning and optimizing follow-up strategies.
目的:探讨血管内皮生长因子(VEGF) mRNA表达作为预测成釉细胞瘤(AM)复发的独立生物标志物,并评估其指导手术策略的潜力。方法:回顾性队列研究纳入了200例于2021年1月至2023年12月接受首次手术的原发性AM患者。将患者分为刮除组(n = 77)和扩大切除组(n = 123)。采用RT-qPCR定量检测肿瘤囊壁中VEGF mRNA的相对表达量。采用Kaplan-Meier分析和Cox回归分析无复发生存期(RFS)及危险因素。比较两组围手术期结局及并发症。采用Cox比例风险回归模型进行单因素和多因素分析。结果:复发组VEGF mRNA表达量(4.66±1.42)明显高于非复发组(3.24±2.02,P < 0.001)。ROC曲线分析发现,预测复发的最佳VEGF截止值为4.88 (AUC = 0.694)。这种分子分层揭示了一个深刻的差异:vegf -高组的2年RFS(77.4%)明显低于vegf -低组(94.9%,P < 0.001)。延长切除的2年RFS高于刮除(96.0% vs. 79.5%),结论:高VEGF mRNA表达是AM复发的一个强大的、独立的生物标志物,其预后影响超过手术选择。术前VEGF评估具有指导个体化手术计划和优化随访策略的重要潜力。

Introduction

To compare the upper airway dimensions between patients with non-syndromic cleft lip and palate (NSCLP) and skeletal class I control group using three-dimensional imaging.

Methods

Using a retrospective cohort study, the investigators enrolled a sample of patients from the Orthodontic Department of the Affiliated Stomatological Hospital of Nanjing Medical University during 2014 and 2018. The primary predictor variable was dentofacial skeleton (NSCLP vs. skeletal class I). The main outcome was three-dimensional upper airway morphology, which included volume, minimum cross-sectional area, height, and symmetry. Appropriate statistics were computed using P < 0.05 as statistical significance.

Results

The study included 51 NSCLP patients and 53 class I controls, with comparable age and gender distribution. Three-dimensional analysis revealed significant morphological differences: compared to the class I group, NSCLP patients exhibited a larger nasopharyngeal volume (p < 0.01) and a larger minimum cross-sectional area in the nasopharynx (p < 0.05) and palatopharynx (p < 0.01), but a reduced height of the upper airway (p < 0.05) and palatopharyngeal airway (p < 0.01). Furthermore, in unilateral NSCLP patients, the transverse diameters of the nasopharynx and palatopharynx were significantly smaller on the affected side compared to the normal side (p < 0.05). While bilateral NSCLP and class I groups demonstrated symmetry at the nasopharyngeal and palatopharyngeal levels, both exhibited significant asymmetry at the glossopharyngeal segment (p < 0.05).

Conclusion

Our findings conclusively define the specific three-dimensional differences in the NSCLP upper airway, which include an enlarged yet foreshortened nasopharynx and consistent lateral asymmetries. These structural nuances must be considered in the interdisciplinary management of cleft lip and palate to optimize functional and structural results.

Background

Mandibular defect reconstruction after tumor resection poses significant challenges in oral and maxillofacial surgery. The free fibula flap is widely used and effective for reconstructing such defects. Traditional manual segmentation and stabilization can lead to inaccuracies; while 3D-printed guides improve cutting precision, they often overlook the stabilization of bone segments. The conventional surgical template system consists of three separate guides: a tumor removal guide, a fibula cutting guide, and a reconstruction guide, which requires manual detachment and reshaping of fibula segments before reconstruction. In contrast, the spliced surgical template system integrates an additional fibula cutting frame and reconstruction frame. This allows the fibula cutting guides to transform directly into the reconstruction guide without detaching the segments, thereby simplifying the workflow and improving stabilization accuracy. This study evaluates a spliced surgical template system and compares its accuracy in stabilizing bone segments with that of conventional systems.

Patient and method

A retrospective cohort study was conducted for patients who underwent mandibular tumor resection and free fibula flap reconstruction at Shanghai Ninth People’s Hospital from 01/01/2022 to 31/03/2025. Patients were divided into two groups based on whether they used conventional or spliced surgical template systems. Preoperative virtual surgical planning was adapted to create 3D models, cutting guides, and reconstructing guides. Postoperative CT scans were also analyzed to assess reconstruction accuracy by measuring deviations in three dimensions.

Result

20 patients were included; 10 used the spliced surgical template system, and the rest used the conventional ones. The spliced system showed significantly more minor errors in reconstruction accuracy than the other. The offset was X-axis 0.31 [0.13, 0.97] mm, Y-axis 0.32 [0.11, 0.78] mm, and Z-axis 0.37 [0.06, 0.47] mm for the spliced system, versus 4.03 [0.61, 18.49] mm, 3.50 [0.66, 13.94] mm, and 3.14 [0.85, 7.25] mm for the conventional system, which were all statistically significant (p < 0.05).

Conclusion

The spliced surgical template system provides higher accuracy and stability in mandibular reconstruction with the free fibula flap. It reduces errors in the positioning of fibula segments, resulting in improved reconstruction precision and potentially contributing to better functional outcomes compared with conventional methods.
背景:下颌骨肿瘤切除后缺损重建是口腔颌面外科的一大挑战。游离腓骨瓣在腓骨缺损重建中应用广泛,效果良好。传统的人工分割和稳定会导致不准确;虽然3d打印导向器提高了切割精度,但它们往往忽略了骨段的稳定性。传统的手术模板系统由三个独立的导向器组成:肿瘤切除导向器、腓骨切割导向器和重建导向器,重建前需要手工剥离和重塑腓骨节段。相比之下,拼接手术模板系统集成了一个额外的腓骨切割框架和重建框架。这使得腓骨切割导轨可以直接转换为重建导轨,而无需分离节段,从而简化了工作流程并提高了稳定精度。本研究评估了拼接手术模板系统,并比较了其在稳定骨段的准确性与传统系统。患者与方法:对2022年1月1日至2025年3月31日在上海市第九人民医院行下颌骨肿瘤切除术及游离腓骨皮瓣重建术的患者进行回顾性队列研究。患者根据是否使用常规或拼接手术模板系统分为两组。术前虚拟手术计划适用于创建三维模型、切割导片和重建导片。术后CT扫描也通过测量三维偏差来评估重建的准确性。结果:纳入20例患者;10例采用拼接手术模板系统,其余采用常规手术模板系统。拼接系统在重建精度上的小误差明显大于其他拼接系统。与传统系统的4.03 [0.61,18.49]mm、3.50 [0.66,13.94]mm、3.14 [0.85,7.25]mm相比,拼接系统的x轴偏移量为0.31 [0.13,0.97]mm、y轴偏移量为0.32 [0.11,0.78]mm、z轴偏移量为0.37 [0.06,0.47]mm,差异均有统计学意义(p结论:拼接手术模板系统在游离腓骨瓣下颌骨重建中具有更高的准确性和稳定性。它减少了腓骨节段定位的错误,从而提高了重建精度,与传统方法相比,可能有助于更好的功能结果。

To evaluate the impact of early postoperative occlusal intervention on mandibular border movement and functional recovery in patients with maxillofacial trauma and malocclusion.

Methods

In this retrospective 1:1 matched study, 184 patients treated during December 2019 to December 2023 were allocated to intervention (n = 92) and control (n = 92) groups. Controls received conventional postoperative care. The intervention group received additional systematic occlusal intervention initiated within one week post-surgery, comprising intermaxillary traction, occlusal splint therapy, and targeted occlusal training. Outcomes assessed included the mandibular border movement index (MBMI), Visual Analogue Scale (VAS), pressure pain threshold (PPT), Jaw Functional Limitation Scale (JFLS), and Oral Health Impact Profile-5 (OHIP-5). Complications were also recorded.

Results

At 3 months, both groups showed significant improvement in all MBMI parameters (maximum mouth opening, protrusion, lateral excursions) and the composite score, with the intervention group demonstrating superior outcomes (P < 0.05). The intervention group also exhibited significantly greater reductions in VAS scores and greater increases in PPT (P < 0.05). Similarly, significantly greater improvements were observed in the intervention group for all JFLS domains (mastication, vertical mobility, emotional/verbal expression) and OHIP-5 items, along with their total scores (P < 0.05). The complication rate did not differ significantly between groups (P > 0.05).

Conclusion

Early systematic occlusal intervention effectively promotes mandibular border movement recovery, alleviates orofacial pain, and enhances jaw function and oral health-related quality of life in patients with maxillofacial trauma and malocclusion, without increasing complication risks, representing a safe and effective adjunctive treatment strategy.
目的:探讨术后早期咬合干预对颌面部外伤错颌患者下颌缘运动及功能恢复的影响。方法:在这项回顾性1:1匹配研究中,将2019年12月至2023年12月期间接受治疗的184例患者分为干预组(n = 92)和对照组(n = 92)。对照组接受常规术后护理。干预组在术后一周内开始进行系统的咬合干预,包括上颌间牵引、咬合夹板治疗和有针对性的咬合训练。评估的结果包括下颌边界运动指数(MBMI)、视觉模拟量表(VAS)、压痛阈值(PPT)、颌骨功能限制量表(JFLS)和口腔健康影响概况-5 (OHIP-5)。并发症也有记录。结果:3个月时,两组MBMI各项参数(最大开口、突出、侧偏移)及综合评分均有显著改善,干预组疗效更佳(P < 0.05)。干预组VAS评分降低显著高于对照组,PPT评分升高显著高于对照组(P < 0.05)。同样,干预组在JFLS各领域(咀嚼、垂直活动能力、情绪/言语表达)和OHIP-5项目及其总分均有显著性改善(P < 0.05)。两组间并发症发生率差异无统计学意义(P < 0.05)。结论:颌面外伤、错颌患者早期系统的咬合干预可有效促进下颌缘运动恢复,减轻口面疼痛,提高颌功能和口腔健康相关生活质量,且不增加并发症风险,是一种安全有效的辅助治疗策略。

Introduction

Oral squamous cell carcinoma (OSCC) is a major global health burden, traditionally associated with tobacco, alcohol, and betel quid. In recent years, however, cases have emerged among individuals without these classic risk factors. Chronic exposure to electromagnetic fields (EMFs) from mobile phones and wireless devices has been classified as possibly carcinogenic, yet its potential role in oral carcinogenesis has not been systematically studied.

Technical Note

This article highlights the biological plausibility that prolonged, localized EMF exposure may contribute to DNA damage, oxidative stress, and epigenetic modifications in oral epithelial tissues. Evidence from pilot cytogenetic studies, in vitro models, and limited epidemiological data observed increased micronucleus frequency and altered cellular stress responses in buccal mucosal cells of long-term mobile phone users. While direct causal data in OSCC remain absent, these findings suggest that EMFs could act alone or in synergy with established carcinogens.

Discussion

The technical note underscores the urgent need for in vitro, in vivo, and epidemiological studies to evaluate whether chronic EMF exposure contributes to oral carcinogenesis. Recognizing this hypothesis is not alarmist but rather a call for rigorous and unbiased investigation. If validated, such evidence could inform preventive guidelines and public health policy for emerging exposures.
口腔鳞状细胞癌(OSCC)是一个主要的全球健康负担,传统上与烟草、酒精和槟榔有关。然而,近年来,在没有这些典型危险因素的个体中出现了病例。长期暴露于来自移动电话和无线设备的电磁场(emf)已被归类为可能致癌,但其在口腔致癌中的潜在作用尚未得到系统研究。技术说明:这篇文章强调了长期的、局部的EMF暴露可能导致口腔上皮组织的DNA损伤、氧化应激和表观遗传修饰的生物学合理性。来自初步细胞遗传学研究、体外模型和有限流行病学数据的证据表明,长期使用手机的人口腔黏膜细胞微核频率增加,细胞应激反应改变。虽然在OSCC中没有直接的因果数据,但这些发现表明,电磁场可以单独作用,也可以与已知的致癌物协同作用。讨论:技术说明强调迫切需要进行体外、体内和流行病学研究,以评估慢性EMF暴露是否有助于口腔致癌。认识到这一假设并不是危言耸听,而是呼吁进行严格和公正的调查。如果得到证实,这些证据可以为新出现的暴露提供预防指南和公共卫生政策。

Objective

Periodontitis is a prevalent chronic inflammatory disease characterized by progressive destruction of periodontal tissues, with alveolar bone defects posing significant challenges for clinical treatment. This research aimed to ascertain the clinical efficacy of minimally invasive bone grafting combined with concentrated growth factor (CGF) for treating periodontitis.

Methods

Seventy-eight patients with periodontitis and bone defects were randomized into the control group (received guided tissue regeneration (GTR) combined with bone grafting treatment) and the test group (received GTR combined with minimally invasive bone grafting and CGF treatment). Postoperative pain at 1 day, 3 days, and 7 days postoperatively, mucosal healing at 7 days postoperatively, probing depth (PD), clinical attachment level (CAL), gingival recession depth (GRD), bleeding index (BI), gingival index (GI), and the alveolar bone defect depth preoperatively and at 6 months postoperatively were compared, changes in implant new bone thickness and density at 3 and 6 months postoperatively were tested by cone-beam computed tomography (CBCT), and implantation success rate and postoperative complications were compared.

Results

The test group exhibited lower pain scores at 3 and 7 days (P < 0.05), improved mucosal healing (P < 0.05), and superior periodontal indicators (PD, CAL, GRD, BI, GI) at 6 months (P < 0.05). CBCT revealed greater bone thickness/density in the test group (P < 0.05). Complication rates were lower in the test group (P < 0.05), with no significant difference in implantation success (P > 0.05).

Conclusion

Minimally invasive bone grafting combined GTR with CGF improves periodontal conditions in patients with periodontitis complicated by bone defects, achieves good bone regeneration results, and reduces postoperative complications.

Simplifying intermaxillary fixation in orthognathic surgery using customized surgical archwire with clear aligners: a technical note and exemplifying case 在正颌手术中使用带明确矫正器的定制手术弓丝简化上颌间固定:一个技术说明和范例案例。
IF 2 3区 医学 Q2 DENTISTRY, ORAL SURGERY & MEDICINE Pub Date : 2026-03-01 Epub Date: 2025-11-19 DOI: 10.1016/j.jormas.2025.102662

Background

Clear aligners are increasingly integrated into orthognathic surgery workflows. However, the lack of rigid intraoperative anchorage limits their use to mild or moderate cases, as aligners alone cannot ensure stable intermaxillary fixation.

Objective

To describe a simplified, reproducible, and cost-effective technique using a customized cobalt–chromium surgical archwire that enables stable intermaxillary fixation in patients treated with clear aligners.

Technical note

A 47-year-old woman with skeletal Class III malocclusion underwent bimaxillary orthognathic surgery under aligner treatment. A CAD-designed cobalt–chromium archwire with interdental posts was bonded using a conventional three-step adhesive protocol. The procedure required approximately 25 min and allowed precise intraoperative traction without detachment or deformation. The optional use of a silicone positioning key improved bonding accuracy and reproducibility.

Conclusion

This technique provides rigid and evenly distributed anchorage without removing aligner attachments or adding brackets or screws. By enabling stable intra- and postoperative fixation, it removes a key limitation of aligner-based surgical planning. This expands the applicability of clear aligners to more complex orthognathic cases, such as segmental osteotomies or asymmetrical corrections, and improves the integration of aligners into modern surgical workflows.
背景:清晰对准器越来越多地融入正颌手术工作流程。然而,术中缺乏刚性锚固限制了它们在轻度或中度病例中的应用,因为仅靠矫直器不能确保稳定的上颌间固定。目的:描述一种使用定制钴铬手术弓丝的简化、可重复性和成本效益的技术,使使用透明矫正器治疗的患者能够稳定地固定上颌间。技术说明:一位47岁的女性骨骼III类错颌在矫正器治疗下接受了双颌正颌手术。采用传统的三步粘接方法,将cad设计的钴铬弓丝与牙间桩进行粘接。手术大约需要25分钟,术中精确牵引,无脱离或变形。硅胶定位键的可选使用提高了粘合精度和再现性。结论:该技术提供了刚性和均匀分布的支抗,无需移除对准器附着物或添加支架或螺钉。通过实现稳定的内固定和术后固定,它消除了基于对准器的手术计划的一个关键限制。这扩大了清晰对准器在更复杂的正颌病例中的适用性,如节段性截骨或不对称矫正,并改善了对准器与现代外科工作流程的整合。

Background

To investigate the characteristics, causes, and risk factors of perioperative mortality (POM) in patients undergoing surgery for head and neck cancer (HNC).

Patients and Methods

Medical records of HNC patients treated between 1999 and 2024 were reviewed. Sixty-six patients who experienced POM were identified and compared with 132 matched controls (matched for tumor site, stage, and type of surgery). Data included demographics, comorbidities, tumor features, treatment history, perioperative management, and causes of death. POM causes were categorized as surgical, medical, mixed, or personal. Risk factors were assessed using univariate and multivariate logistic regression.

Results

Among 198 patients (66 POM, 132 controls), those with POM were older, had more comorbidities, advanced disease, and prior radiotherapy. They also showed higher ASA grades, longer operations, greater blood loss, and more frequent tracheotomy (all p < 0.05). Most deaths occurred postoperatively, with medical complications predominating. Independent predictors of POM were comorbidities, advanced stage, ASA grade <III, blood loss >600 ml, and tracheotomy.

Conclusion

Perioperative mortality in HNC surgery results from multifactorial causes, with both surgical and medical complications contributing significantly. Identifying high-risk patients based on preoperative status and operative parameters may help optimize perioperative care and reduce mortality.
背景:探讨头颈癌(HNC)手术患者围手术期死亡率(POM)的特点、原因及危险因素。患者与方法:回顾1999 ~ 2024年收治的HNC患者的医疗记录。66例经历POM的患者被确定并与132例匹配对照(匹配肿瘤部位、分期和手术类型)进行比较。数据包括人口统计学、合并症、肿瘤特征、治疗史、围手术期管理和死亡原因。POM的原因分为手术、医疗、混合和个人原因。采用单因素和多因素logistic回归评估危险因素。结果:198例患者(66例POM, 132例对照)中,POM患者年龄较大,合并症较多,病情进展,既往放疗较多。ASA分级高,手术时间长,出血量大,气管切开次数多(p < 0.05)。大多数死亡发生在术后,以医学并发症为主。POM的独立预测因子为合并症、晚期、ASA分级600 ml和气管切开术。结论:HNC手术围手术期死亡率是由多因素引起的,手术并发症和内科并发症均有显著影响。根据术前状态和手术参数识别高危患者有助于优化围手术期护理和降低死亡率。
