Stabilization appliances (Michigan splints) are considered well-studied and widely adopted for managing bruxism and temporomandibular disorders (TMDs). Traditionally, these appliances have been fabricated by wax modeling and pressing resin onto casts made from irreversible hydrocolloid or silicone impressions. This article provides a detailed description of an all-digital workflow that uses intraoral scanning and computer-aided design (CAD) software to design a stabilization splint on a digital cast that can be manufactured autonomously by a computer-aided manufacturing (CAM) grinding machine in a subtractive procedure. The workflow is applicable to both dentists and technicians. Special attention is given to aspects and procedures that are important for the successful fabrication of the splint. Working without a cast can save time and money, and the use of CAD-CAM technology provides a homogeneous splint material quality.

在治疗磨牙症和颞下颌关节紊乱症(TMD)方面,稳定矫治器(密歇根夹板)已得到充分研究和广泛采用。传统上,这些矫治器的制作方法是在不可逆转的水胶体或硅胶印模上用蜡建模并将树脂压在铸模上。本文详细介绍了一种全数字化的工作流程,该流程使用口内扫描和计算机辅助设计(CAD)软件在数字铸模上设计稳定夹板,并通过计算机辅助制造(CAM)磨床在减法程序中自主制造。该工作流程适用于牙医和技师。其中特别关注了对成功制作夹板非常重要的方面和程序。无石膏工作可节省时间和金钱,CAD-CAM 技术的使用可提供均匀的夹板材料质量。

Objective: To evaluate the survival of fully guided implants placed with a hollow tooth-supported computerized surgical guide (TSSG).

Method and materials: This retrospective study included 94 patients who underwent implant placement using freehand or TSSG by the same operator between 2015 and 2020. Early implant failures occurring within 1-year post-rehabilitation were assessed.

Results: In the study, two types of implants were placed using two different techniques: TSSG and freehand. The TSSG group consisted of 84 S implants and 100 LP implants, and the freehand group included 90 S implants and 94 LP implants. The results showed that more implants survived when placed freehand compared to TSSG (181 [98.4%] vs 172 [93.5%], respectively, P .05). The only significant factor affecting the success rate was the type of implant, with LP implants having a higher survival rate in the TSSG group (P .05).

Conclusion: Surgeons should consider the impact of implant type on survival rates when utilizing the TSSG system.

目的评估使用空心牙支持计算机化手术导板(TSSG)植入的全引导种植体的存活率:这项回顾性研究纳入了2015年至2020年间由同一操作者使用徒手(FH)或牙支持计算机化手术导板(TSSG)植入种植体的94名患者。对康复后一年内发生的早期种植失败进行了评估:在这项研究中,使用两种不同的技术植入了两种类型的种植体:结果:研究采用两种不同的技术植入了两种类型的种植体:TSSG 和 FH。TSSG 组包括 84 个 S 型种植体和 100 个 LP 型种植体,而 FH 组包括 90 个 S 型种植体和 94 个 LP 型种植体。结果显示,与 TSSG 相比,FH 植入体的存活率更高(分别为 181 个(98.4%)和 172 个(93.5%),P < 0.05)。影响成功率的唯一重要因素是种植体类型,TSSG 组中 LP 种植体的存活率更高(P < 0.05):外科医生在使用 TSSG 系统时应考虑植入物类型对存活率的影响。

Objectives: The purpose of the present study was the radiographic evaluation of endodontically treated teeth presenting periapical radiolucency and unintentional overfilling with gutta-percha or sealer on treatment outcome and persistence of the extruded materials.

Method and materials: After assessment using periapical index (PAI), 202 roots filled with gutta-percha and zinc oxide-eugenol sealer (Roth 811, Roth International), exhibiting unintentional overfilling and periapical radiolucency were selected. All cases had at least 1 year of follow-up. Type of extruded material, periapical status, and removal/persistence of the extruded material were evaluated by two independent observers. Data were statistically analyzed using logistic and linear regression analysis.

Results: Tooth location (P .001), follow-up period (P .001), and type of extruded material (P = .004) significantly influenced treatment outcomes. Specifically, posterior roots exhibited better outcomes compared to anterior, and cases with overfilling of sealer showed superior healing potential compared to those with gutta-percha overfilling. Additionally, longer recall periods were associated with improved treatment success. The type of extruded material (P .001) and follow-up period (P .001) significantly affected the presence of extruded material in the follow-up radiograph. The persistence of extruded material was greater when gutta-percha was extruded, and extruded materials were less detected when the follow-up period was longer.

Conclusion: Teeth with periapical radiolucency and unintentional overfilling require longer follow-up intervals for effective monitoring of healing. Treatment outcome was associated with the type of extruded materials used in the present study. The persistence of those materials in the periapex did not affect healing.

研究目的本研究的目的是对根管治疗后出现根尖周放射状出血和无意中过度填充古塔波胶或封闭剂的牙齿进行放射学评估,以了解治疗效果和挤出材料的持久性:在使用根尖周指数(PAI)进行评估后,选择了 202 个使用古塔漆和氧化锌丁香酚封闭剂(Roth 811,Roth International)填充的牙根,这些牙根表现出无意过度填充和根尖周放射状突起。所有病例均进行了至少 1 年的随访。由两名独立观察员对挤出材料的类型、根尖周状况以及挤出材料的去除/存留情况进行评估。数据采用逻辑和线性回归分析法进行统计分析:牙齿位置(P有根尖周围放射线和无意过度充填的牙齿需要更长的随访间隔,以有效监测愈合情况。治疗结果与本研究中使用的挤压材料类型有关。这些材料在根尖周围的持续存在并不影响愈合。

Objectives: To evaluate the survival rate of minimally invasive semipermanent occlusal polymethyl methacrylate (PMMA) onlays/veneers in previous temporomandibular disorder (TMD) patients with severe tooth wear and with a loss of vertical dimension after up to 7 years.

Method and materials: This case series was designed as a follow-up evaluation with consecutive patient recruitment. All patients bearing the indication for this kind of rehabilitation were treated by the same clinician using the same adhesive methodology. The study included 22 patients (3 men/19 women), with a mean ± SD age of 50.7 ± 11.6 years. Controls followed within the first 4 weeks (and subsequently as required). Failure criteria included damage by fracture, chipping, and retention loss. Survival rates were determined based on the Kaplan-Meier analysis.

Results: 328 semipermanent occlusal/incisal veneers were included (142 maxillary/186 mandibular teeth). Almost 80% of the restorations were in place and in function when starting the follow-up treatment after 180 days; failures predominantly occurred within the first 3 to 6 months but proved reparable. Depending on the patients' priorities, scheduled replacements followed successively, and more than 65% did not show repair or any renewal needs for more than 360 days.

Conclusion: Within the limitations of this study the survival rates of occlusal veneers made of PMMA were sufficiently high to allow for consecutive treatment of the respective teeth by means of permanent restorations while preserving the restored vertical dimension. In patients with severe tooth wear and a TMD history, semipermanent restorative therapy with occlusal PMMA onlays/veneers would seem a noteworthy option.

目的评估微创半永久性咬合聚甲基丙烯酸甲酯(PMMA)嵌体/veneers在既往颞下颌关节紊乱症(TMD)患者中的存活率:本系列病例是通过连续招募患者进行随访评估而设计的。所有符合这种修复适应症的患者均由同一临床医生使用相同的粘接方法进行治疗。研究包括 22 名患者(3 男/19 女),平均年龄为 50.7 [11.6]岁。对照组在最初 4 周内进行了随访(随后根据需要进行了随访)。失败标准包括断裂、崩裂和固位丧失。根据 Kaplan-Meier 分析法确定存活率:共纳入 328 个半永久性咬合/咬合贴面(142 个上颌牙/186 个下颌牙)。在 180 天后开始的后续治疗中,几乎 80% 的修复体都已就位并发挥功能;失败主要发生在最初的 3 到 6 个月内,但都证明是可以修复的。根据患者的优先顺序,修复体会陆续更换,超过 65% 的修复体在 360 天内没有出现修复或任何更新需求:在这项研究的局限性范围内,PMMA 制成的咬合贴面的存活率很高,可以通过永久性修复体对相关牙齿进行连续治疗,同时保留修复后的垂直尺寸。对于牙齿磨损严重并有TMD病史的患者,使用PMMA咬合贴面/veneers进行半永久性修复治疗似乎是一个值得注意的选择。

Objective: Varying levels of sex hormones across the menstrual cycle in young systemically healthy females may alter tissue responses to plaque, resulting in increased gingival inflammation. Also, higher severity and prevalence of gingivitis has been demonstrated in adult women than men, attributed to hormonal changes. Further, it has been reported that gingivitis raises the levels of systemic inflammatory markers such as C-reactive protein. This interventional trial aimed to evaluate the effect of supragingival scaling on serum high-sensitivity C-reactive protein (hsCRP) levels along with periodontal parameters in systemically healthy women of reproductive age with natural gingivitis.

Method and materials: In total, 57 women of reproductive age were enrolled into two groups. The test group (n = 30) comprised systemically healthy women with gingivitis who received supragingival scaling. The control group (n = 27) included systemically and periodontally healthy women. Periodontal parameters (Gingival Index, Plaque Index, pocket probing depth, bleeding on probing) and serum hsCRP levels were recorded at baseline for both the groups. Follow-up of test group participants was done at 3 and 6 months.

Results: Serum hsCRP and periodontal parameters were significantly higher in the test group than in the control group at baseline, and this decreased significantly after treatment in the test group at the 6-month follow-up (P ≤ .05). Gingival Index, bleeding on probing, and hsCRP in the test group at 6 months were reduced to the baseline levels of systemically and periodontally healthy women.

Conclusion: Treatment of gingival inflammation can help in lowering the systemic and local inflammation to the levels of systemically and periodontally healthy women.

目的:全身健康的年轻女性在月经周期中性激素水平的变化可能会改变组织对牙菌斑的反应,从而导致牙龈炎症加重。此外,成年女性牙龈炎的严重程度和发病率也高于男性,这都归因于荷尔蒙的变化。此外,据文献报道,牙龈炎会提高全身炎症标志物(如 C 反应蛋白)的水平。这项干预性试验旨在评估龈上洁治对血清高敏 C 反应蛋白(hsCRP)水平的影响,以及对患有天然牙龈炎的全身健康育龄妇女牙周参数的影响。试验组(人数=30)由患有牙龈炎并接受龈上洁治的全身健康妇女组成。对照组(人数=27)包括全身和牙周健康的女性。记录两组基线时的牙周参数[牙龈指数(GI)、牙菌斑指数(PI)、龈袋探诊深度(PPD)、探诊出血量(BOP)]和血清 hsCRP 水平。在 3 个月和 6 个月时对测试组参与者进行随访:结果:测试组的血清 hsCRP 和牙周参数在基线时明显高于对照组,而在治疗后 6 个月的随访中,测试组的血清 hsCRP 和牙周参数明显降低(p≤0.05)。试验组的 GI、BOP 和 hsCRP 在 6 个月后降至全身和牙周健康女性的基线水平:结论:治疗牙龈炎症有助于降低全身和局部炎症,使其达到全身和牙周健康女性的水平。

Objectives: This study aimed to evaluate the effect of the clinical removal of fixed partial dentures on oral health-related quality of life and the anxiety values of individuals and to determine the clinical factors of high anxiety levels.

Method and materials: In total, 300 participants were included in the study. Six different reasons for the clinical removal of fixed partial dentures (oral examination, denture renewal, endodontic treatment, tooth extraction, periodontal treatment, and composite filling restoration) were defined. The United Kingdom Oral Health-Related Quality-of-Life Measure (OHRQoL-UK), the Modified Dental Anxiety Scale (MDAS), and the Spielberger State-Trait Anxiety Inventory- State (STAI-S) and Trait (STAI-T) were answered. The reason groups were compared using one-way analyses of variance. Binary logistic regression analyses were performed to evaluate the risk factors for high anxiety.

Results: There was no significant difference in OHRQoL-UK scores (P = .279) among the reason groups, but there were significant differences in MDAS, STAI-S, and STAI-T scores (P = .004, P .001, P = .018, respectively) among the reason groups. Endodontic treatment, tooth extraction, and sex were determined to be risk factors, considering the anxiety scales.

Conclusions: Females are 2.2 times more likely to have trait anxiety than men. Although the effect of the reason for the clinical removal of fixed partial dentures on oral health-related quality of life was similar among the groups, it is concluded that endodontic treatment and tooth extraction reasons for the clinical removal of fixed partial dentures could be risk factors for high anxiety regardless of fixed partial denture usage time.

研究目的本研究旨在评估临床摘除固定局部义齿(FPD)对口腔健康相关生活质量(OHRQoL)和个人焦虑值的影响,并确定高焦虑水平的临床因素:本研究共纳入 300 名参与者。定义了临床拔除FPD的六种不同原因(口腔检查、义齿更新、牙髓治疗、拔牙、牙周治疗和复合材料充填修复)。对英国口腔健康相关生活质量测量(OHRQoL-UK)、改良牙科焦虑量表(MDAS)、斯皮尔伯格状态-特质焦虑问卷-状态(STAI-S)和特质(STAI-T)进行了问卷调查。采用单因素方差分析(ANOVA)对原因组进行比较。为评估高度焦虑的风险因素,进行了二元逻辑回归分析:结果:不同原因组的 OHRQoL-UK 评分无明显差异(P=.279),但 MDAS、STAI-S 和 STAI-T 评分有明显差异(P=.004,PC 结论:女性是男性的 2.2 倍:女性患特质焦虑的几率是男性的 2.2 倍。尽管临床拔除FPD的原因对各组OHRQoL的影响相似,但结论是,无论FPD使用时间长短,牙髓治疗和拔牙等临床拔除FPD的原因都可能是导致高度焦虑的危险因素。

Objective: To determine the oral health status of patients on maintenance hemodialysis and to identify the factors influencing their oral health.

Method and materials: This observational study included 1,186 patients with chronic kidney disease who received maintenance hemodialysis across 33 hospitals in China. The patients were recruited for a questionnaire survey between April and August 2023 at Beijing Chaoyang Hospital using stratified sampling. Data collection tools included the General Information Questionnaire for Maintenance Hemodialysis Patients, the Oral Health Assessment Tool, the Pittsburgh Sleep Quality Index, and the Hospital Anxiety and Depression Scale. Spearman rank correlation coefficients were used to assess the relationships between the oral health of patients on maintenance hemodialysis and continuous variables such as sleep quality and emotional status. Multiple linear regression analysis was employed to explore the relationship between oral health and various variables.

Results: The oral health scores of the patients ranged from 8 to 22, with a mean score of 12.54 ± 2.63. The final model of the multiple linear regression analysis indicated a goodness of fit of 22.19%. Independent factors affecting the oral health of patients included smoking, the proportion of medical expenses, water consumption, sleep quality, and anxiety scores (all P .05). High levels of smoking, substantial medical expenses, poor sleep quality, and elevated anxiety scores were risk factors for poor oral health (all P .05). Adequate daily water intake served as a protective factor for oral health (P .05).

Conclusion: This study proposes targeted interventions to enhance the management and improvement of oral health in patients on hemodialysis, aiming to provide highly personalized and effective oral health care. These interventions are expected to improve oral health outcomes in future clinical practice.

目的:确定维持性血液透析患者的口腔健康状况,并找出影响其口腔健康的因素:确定维持性血液透析(MHD)患者的口腔健康状况,并找出影响其口腔健康的因素:这项观察性研究纳入了中国 33 家医院的 1,186 名接受血液透析治疗的慢性肾病患者。这些患者于 2023 年 4 月至 8 月期间在北京朝阳医院接受了分层抽样的问卷调查。数据收集工具包括《维持性血液透析患者一般信息调查表》、《口腔健康评估工具》、《匹兹堡睡眠质量指数》和《医院焦虑抑郁量表》。斯皮尔曼等级相关系数用于评估血液透析患者的口腔健康状况与睡眠质量和情绪状态等连续变量之间的关系。采用多元线性回归分析来探讨口腔健康与各种变量之间的关系:患者的口腔健康评分从 8 分到 22 分不等,平均分为(12.54±2.63)分。多元线性回归分析的最终模型显示拟合优度为 22.19%。影响患者口腔健康的独立因素包括吸烟、医疗费用比例、饮水量、睡眠质量和焦虑评分(均为 P <0.05)。吸烟率高、医疗费用高、睡眠质量差和焦虑评分高是口腔健康不良的风险因素(均为 P <0.05)。每日充足的饮水量是口腔健康的保护因素(P < 0.05):本研究提出了加强血液透析患者口腔健康管理和改善的针对性干预措施,旨在提供高度个性化和有效的口腔健康护理。这些干预措施有望在未来的临床实践中改善口腔健康状况。

Objectives: Our aim was to investigate the impact of smoking on pocket closure at six months after treatment of severe periodontitis, in relation to residual clinical inflammation.

Method and materials: The clinical records of deep pockets (probing depth≥6 mm, n=984) in 46 individuals with periodontitis were analyzed. Following baseline clinical assessments (plaque index, probing depth, clinical attachment level, and bleeding on probing), non-surgical periodontal treatment was performed. Clinical assessments were repeated at 2 and 24 weeks after periodontal therapy. A logistic regression model using generalised estimation equations (GEE) adapting the cluster robust standard errors was performed to investigate potential associations between bleeding on probing and pocket closure at post-treatment 24 weeks.

Results: Absence of bleeding at two weeks after non-surgical treatment related to pocket closure after six-months. Pockets that do not bleed neither at baseline nor two weeks (OR=2.7; P <.005) and pockets of non-smokers (OR=6.32; P <.001) and females (OR=1.79; P =.022) associated with pocket closure at six months.

Conclusion: Pocket closure is associated with being a non-smoker and the absence of inflammation after non-surgical periodontal treatment, which indicates the importance of smoking cessation and inflammation control in achieving optimal clinical outcomes.

目的我们的目的是研究吸烟对重度牙周炎治疗后 6 个月的牙周袋闭合的影响,以及与残余临床炎症的关系:分析了 46 名牙周炎患者的深袋临床记录(探诊深度≥6 毫米,n=984)。在进行基线临床评估(菌斑指数、探诊深度、临床附着水平和探诊出血)后,进行非手术牙周治疗。牙周治疗后 2 周和 24 周再次进行临床评估。使用广义估计方程(GEE)和聚类稳健标准误差建立逻辑回归模型,研究探诊出血与治疗后24周袋闭合之间的潜在关联:结果:非手术治疗两周后无出血与六个月后的牙周袋闭合有关。基线和两周时均未出血的牙周袋(OR=2.7; P 结论:牙周袋闭合与非手术治疗有关:牙周袋闭合与非吸烟者和非手术牙周治疗后无炎症有关,这表明戒烟和控制炎症对获得最佳临床效果非常重要。

Objective: To evaluate the ability of near-infrared light transillumination (NIR-LT) to detect interproximal enamel and dentinal caries lesions compared to clinical-visual inspection (VI) aided by fibre-optic transillumination (FOTI).

Method and materials: From 170 Finnish adolescents aged 15-17 years, 5294 interproximal surfaces of premolars and molars were examined first clinical-visually aided by FOTI (VI+FOTI) using the International Caries Detection and Assessment System (ICDAS) classification. Subsequently, the surfaces were examined using NIR-LT. The extent of lesions was determined using the modified NIR-LT classification based on the Söchtig criteria. For the analyses, data on upper and lower premolars and molars were combined. Distributions of lesions were presented as frequencies. Differences between VI+FOTI and NIR-LT at the tooth and tooth surface levels were analysed by Chi-square and Fisher's exact tests. Sensitivity and specificity of the NIR-LT method to detect any lesion was performed using VI+FOTI as the gold standard.

Results: By VI+FOTI, 92.4% surfaces were classified as sound and by NIR-LT, 88.2%. Enamel caries lesions were found on 7.0% of the surfaces by VI+FOTI and on 11.6% by NIR-LT. Enamel lesions identified by NIR-LT were nearly double for all examined teeth groups, except for lower molars it was 1.3-fold. In 66% of the surfaces, the differences between NIR-LT and VI+FOTI findings were statistically significant (p<0.001). The sensitivity for all teeth of NIR-LT was 48.4% and the specificity was 91.1%.

Conclusion: Radiation-free NIR-LT method shows considerable potential as a supplementary method for early detection of caries lesions among low caries prevalence adolescents.

目的评估近红外透射光(NIR-LT)与纤维光学透射光(FOTI)辅助的临床-视觉检查(VI)相比,检测近端釉质和牙本质龋损的能力:对170名15-17岁的芬兰青少年的5294颗前臼齿和臼齿的近端间表面进行了检查,首先采用国际龋病检测和评估系统(ICDAS)的分类方法,在FOTI(VI+FOTI)的辅助下进行临床-视觉检查。随后,使用近红外激光扫描仪对牙齿表面进行检查。病变范围是根据索希特标准修改后的 NIR-LT 分类确定的。在进行分析时,将上下前臼齿和臼齿的数据合并在一起。病变分布以频率表示。VI+FOTI和NIR-LT在牙齿和牙齿表面的差异通过Chi-square和费雪精确检验进行分析。以 VI+FOTI 作为金标准,对近红外-LT 方法检测任何病变的敏感性和特异性进行了分析:通过 VI+FOTI,92.4% 的牙面被归类为完好,而通过 NIR-LT 则有 88.2%。VI+FOTI发现7.0%的牙面有龋坏,NIR-LT发现11.6%的牙面有龋坏。在所有受检牙齿组中,近红外荧光透射法发现的釉质病变几乎是前者的两倍,只有下磨牙是后者的 1.3 倍。在 66% 的牙面上,近红外荧光透射法和 VI+FOTI 检测结果之间的差异具有统计学意义(p 结论:近红外荧光透射法和 VI+FOTI 检测结果之间的差异具有统计学意义:无辐射 NIR-LT 方法作为一种辅助方法,在早期发现低龋患率青少年的龋病方面具有相当大的潜力。
