Objective

Dental implants are a considerable financial burden for elderly people and their caregivers. This study aimed to calculate the estimated economic costs of dental implants on the Korean older population.

Materials and Methods

The economic costs of dental implants for adults aged 75 years and older were estimated from a societal perspective, considering both direct and indirect expenditures. We used data from the Korean National Health Insurance Service for the period 2015–2018 to estimate the medical costs. Noninsured medical costs were estimated from research on medical expenses by the National Health Insurance Review and Assessment Service. Indirect costs related to transportation fees and time loss were obtained. The Cochran Armitage trend test was performed to examine the trend of the economic burden of dental implants.

Results

The estimated economic costs showed from 2015 to 2018 (total costs: $26.54–55.66 million, total costs after discount: $17.11–39.56 million). Direct costs, including insured and noninsured medical costs, represented from $25.81 to $47.03 million. Indirect costs, including transportation and time costs, ranged from $0.73 to $1.63 million. The impact of the total dental implant costs was 0.0018%–0.0034% of the Korean annual gross domestic product and 1.03%–1.59% of the annual total costs of dental care benefits.

Conclusions

The estimated economic burden of dental implants significantly increased from 2015 to 2018 in older South Korean adults. These results will provide a foundation and guidance for further health economic studies on the burden of dental implants in the elderly population.

目的：种植牙对老年人及其护理人员来说是一个相当大的经济负担。本研究旨在计算韩国老年人口种植牙的经济成本估算：我们从社会角度估算了 75 岁及以上成年人种植牙的经济成本，同时考虑了直接和间接支出。我们使用了韩国国民健康保险服务机构 2015-2018 年的数据来估算医疗成本。非保险医疗费用是根据国民健康保险审查和评估服务机构对医疗费用的研究估算得出的。与交通费和时间损失相关的间接成本也已获得。对种植牙的经济负担趋势进行了Cochran Armitage趋势检验：估算的经济成本显示，从 2015 年到 2018 年（总成本：2654-5566万美元，折扣后总成本：1711-3956万美元）。直接成本包括保险和非保险医疗成本，从 2581 万美元到 4703 万美元不等。包括交通和时间成本在内的间接成本从 73 万美元到 163 万美元不等。种植牙总成本占韩国年度国内生产总值的 0.0018%-0.0034% ，占牙科保健福利年度总成本的 1.03%-1.59% ：从 2015 年到 2018 年，韩国老年人种植牙的估计经济负担显著增加。这些结果将为进一步开展有关老年人群种植牙负担的健康经济研究提供基础和指导。

Objective

The use of extracted teeth has been introduced as an option for bone grafting. However, the current method requires special machines and solutions, posing significant time and cost. The aim of this study was to evaluate the clinical performance of autogenous raw tooth particles (RTP), a grafting material made from a ground tooth using basic equipment, for alveolar ridge preservation.

Materials and Methods

Twenty-three patients (12 study/11 control), having 14 and 13 sites were included for the study and control groups (commercially available xenograft), respectively. Radiographic measurements were taken at the baseline and the 4-month follow-up appointment. Furthermore, a questionnaire survey concerning the general preference of the type of graft to receive (if needed), before and after knowing the price, was distributed at the completion of the procedure for patients to answer.

Results

Alveolar ridge width change was −1.03 ± 0.64 and −0.84 ± 0.35 for the study and the control groups, respectively. Regarding the height, the study group showed a buccal and lingual change of −0.66 ± 0.48 and −0.78 ± 0.81, respectively, while this was −0.78 ± 0.56 and −0.9 ± 0.41 for the xenograft group. There was no statistically significant difference between the groups. Patients preferred the raw tooth particles over other grafting materials (p = .01).

Conclusion

No core biopsies were taken to evaluate bone formation, which should be done in future studies. Within its limitations, the current study demonstrated that RTP graft could be an alternative graft for bone augmentation, offering a new cost-effective option for clinicians when available.

目的：使用拔出的牙齿作为骨移植的一种选择。然而，目前的方法需要特殊的机器和解决方案，耗费大量时间和成本。本研究的目的是评估自体原牙颗粒（RTP）的临床表现，这是一种使用基本设备从磨碎的牙齿中提取的移植材料，用于牙槽嵴保留：研究组和对照组（市售异种移植材料）分别有 23 名患者（12 名研究组/11 名对照组），14 个和 13 个部位。研究组和对照组分别有 14 个和 13 个部位的异种牙槽骨。此外，在手术结束时还发放了一份问卷调查，内容涉及患者在了解价格前后对接受移植类型（如有需要）的总体偏好：研究组和对照组的牙槽嵴宽度变化分别为-1.03 ± 0.64和-0.84 ± 0.35。在高度方面，研究组的颊侧和舌侧变化分别为-0.66±0.48和-0.78±0.81，而异种移植组为-0.78±0.56和-0.9±0.41。两组之间没有明显的统计学差异。与其他移植材料相比，患者更喜欢原牙颗粒（p = .01）：没有采取核心活检来评估骨形成，今后的研究中应采取这种方法。在其局限性范围内，目前的研究表明 RTP 移植物可以作为骨增量的替代移植物，为临床医生提供了一种新的具有成本效益的选择。

Background

This case report demonstrates the effective clinical application of a 3D-printed, patient-specific polycaprolactone (PCL) resorbable scaffold for staged alveolar bone augmentation.

Objective

To evaluate the effectiveness of a 3D-printed PCL scaffold in facilitating alveolar bone regeneration and subsequent dental implant placement.

Materials and Methods

A 46-year-old man with a missing tooth (11) underwent staged alveolar bone augmentation using a patient-specific PCL scaffold. Volumetric bone gain and implant stability were assessed. Histological analysis was conducted to evaluate new bone formation and graft integration.

Results

The novel approach resulted in a volumetric bone gain of 364.69 ± 2.53 mm³, sufficient to reconstruct the original alveolar bone contour and permit dental implant placement. Histological analysis showed new bone presence and successful graft integration across all defect zones (coronal, medial, and apical), with continuous new bone formation around and between graft particles. The dental implant achieved primary stability at 35 Ncm⁻¹, indicating the scaffold's effectiveness in promoting bone regeneration and supporting implant therapy. The post-grafting planned implant position deviated overall by 2.4° compared with the initial restoratively driven implant plan pre-bone augmentation surgery. The patient reported low average daily pain during the first 48 h and no pain from Day 3.

Conclusions

This proof-of-concept underscores the potential of 3D-printed scaffolds in personalized dental reconstruction and alveolar bone regeneration. It marks a significant step forward in integrating additive manufacturing technologies into clinical practice through a scaffold-guided bone regeneration (SGBR) approach. The trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12622000118707p).

背景：本病例报告展示了三维打印、患者特异性聚己内酯（PCL）可吸收支架在分阶段牙槽骨增量中的有效临床应用：本病例报告展示了三维打印、患者特异性聚己内酯（PCL）可吸收支架在分阶段牙槽骨增量中的有效临床应用：评估三维打印 PCL 支架在促进牙槽骨再生和后续牙种植体植入方面的有效性：一名缺牙（11颗）的46岁男子使用患者特制的PCL支架接受了分阶段牙槽骨增量术。对骨增量和种植体稳定性进行了评估。组织学分析评估了新骨形成和移植物整合情况：结果：这种新方法获得了 364.69 ± 2.53 mm3 的骨增量，足以重建原有的牙槽骨轮廓，并允许种植体植入。组织学分析表明，在所有缺损区（冠状、内侧和根尖）都有新的骨质存在，移植骨成功整合，移植颗粒周围和之间有持续的新骨形成。牙科种植体在 35 Ncm-1 的条件下实现了初步稳定，这表明支架在促进骨再生和支持种植治疗方面非常有效。移植后计划的种植体位置与骨增量手术前最初的修复驱动种植体计划相比，总体偏差为 2.4°。患者在最初的 48 小时内平均每天的疼痛感较低，从第 3 天开始就没有疼痛感了：这一概念验证凸显了三维打印支架在个性化牙科重建和牙槽骨再生方面的潜力。它标志着通过支架引导骨再生（SGBR）方法将增材制造技术融入临床实践迈出了重要一步。该试验已在澳大利亚新西兰临床试验注册中心注册（ACTRN12622000118707p）。

Objectives

To date, no studies have exploited micro-CT in humans to evaluate bone morphology and structure after bone augmentation with CAD/CAM-customized titanium mesh, in mandible and maxilla. The aim of this study was to assess the composition and microstructure of bone biopsy through micro-CT analysis.

Materials and Methods

Bone augmentation at both maxillary and mandible sites was performed on 30 patients randomly treated with customized mesh, either alone (M−) or covered with resorbable membrane (M+), in both cases filled 50:50 with autogenous bone and xenograft. After 6 months, biopsies were taken and micro-CT was performed on consecutive 1-mm-thick VOIs from coronal to apical side, measuring tissue volumes, trabecular thickness, spacing, and number.

Results

In both groups, irrespective of membrane use, bone tissue (M−: 29.76% vs. M+: 30.84%) and residual graft material (M−: 14.87% vs. M+: 13.11%) values were similar. Differences were site-related (maxillary vs. mandibular) with higher percentage of bone tissue and trabecular density of low-mineralized bone and overall bone in the mandible.

Conclusions

The composition and structure of bone tissue, as assessed by micro-CT after alveolar ridge augmentation using CAD/CAM-customized titanium meshes, showed similar features regardless of whether a collagen membrane was applied.

目的：迄今为止，还没有研究利用显微 CT 评估下颌骨和上颌骨使用 CAD/CAM 定制钛网进行骨增量后的骨形态和结构。本研究旨在通过显微 CT 分析评估骨活检的成分和微观结构：对 30 名患者随机进行了上颌和下颌部位的骨增量手术，这些患者要么单独使用定制网片（M-），要么使用可吸收膜覆盖（M+），在这两种情况下，自体骨和异种移植骨的填充比例均为 50:50。6 个月后，采集活组织切片，并从冠状面到顶端对连续的 1 毫米厚的 VOI 进行显微 CT 扫描，测量组织体积、骨小梁厚度、间距和数量：在两组中，无论使用何种膜，骨组织（M-：29.76% vs. M+：30.84%）和残留移植材料（M-：14.87% vs. M+：13.11%）的值相似。差异与部位有关（上颌与下颌），下颌的骨组织百分比和低矿化骨小梁密度以及整体骨质更高：使用 CAD/CAM 定制钛网进行牙槽嵴增量术后，通过显微 CT 评估的骨组织组成和结构显示出相似的特征，无论是否应用胶原蛋白膜。

Purpose

To assess how well torque-limiting devices (TLDs) are known and used by European dentists, and their adherence to screw tightening protocols and screw loosening occurrence through a survey, including the correlation between the dental specialty-of-interest and the recognition, the tightening protocol used, and between the calibration and the occurrence of screw loosening.

Materials and methods

A 10-question survey was distributed to dentists to collect data on their specialty-of-interest, TLD usage, knowledge on TLDs, calibration, the term “preload,” tightening speed, tightening protocols used, and occurrence of screw loosening. Pearson test was used for correlation analysis between the specialty-of-interest and the recognition-based questions, the tightening protocol used, and between the calibration and the frequency of screw loosening.

Results

Of 422 respondents, 24% calibrated their TLDs, 27% knew the term “preload,” 76% selected the correct location to read on TLDs, and 6% was aware of the effect of tightening speed. The correlation between the specialty-of-interest and the recognition-based questions was nonsignificant (p < .05) but was significant for used tightening protocol (p < .001). The correlation between the calibration and the occurrence of screw loosening was nonsignificant (p = 0.16). Tightening protocols' effect on screw loosening was similar, which was mostly observed less than once a year (p < .001).

Conclusions

A lack in dentists' knowledge was found on calibration, the term preload, and the effect of tightening speed, which were not impacted by the dentists' specialty-of-interest, which affected the preferred tightening protocol. The tightening protocol and calibration did not impact the occurrence of screw loosening, which was mostly observed less than once a year.

目的：通过调查评估欧洲牙医对扭矩限制装置（TLD）的了解和使用情况，以及他们对螺钉拧紧协议和螺钉松动发生率的遵守情况，包括牙医感兴趣的专业与认可度之间的相关性、使用的拧紧协议以及校准与螺钉松动发生率之间的相关性：向牙科医生发放了一份包含 10 个问题的调查问卷，以收集他们感兴趣的专业、TLD 的使用情况、对 TLD 的了解、校准、"预紧力 "一词、拧紧速度、使用的拧紧方案以及螺钉松动发生率等方面的数据。在感兴趣的专业与基于识别的问题、使用的拧紧方案之间，以及校准与螺丝松动频率之间，使用了皮尔逊检验进行相关性分析：在 422 名受访者中，24% 的人校准了他们的 TLD，27% 的人知道 "预紧力 "一词，76% 的人选择了 TLD 上的正确读数位置，6% 的人知道拧紧速度的影响。感兴趣的专业与基于识别的问题之间的相关性并不显著（p 结论：牙科医生缺乏相关知识是一个重要原因：牙医对校准、预紧力一词和拧紧速度的影响缺乏了解，而牙医的兴趣专业并不影响他们对首选拧紧方案的选择。拧紧规程和校准对螺钉松动的发生率没有影响，大多数情况下，螺钉松动的发生率低于一年一次。

Objectives

Examine the histomorphometric bone composition, following alveolar ridge preservation techniques and unassisted socket healing.

Materials and Methods

Forty-two patients (42) requiring a single rooted tooth extraction were randomly allocated into three groups (n = 14 per group): Group 1: Guided Bone Regeneration (GBR) using deproteinised bovine bone mineral (DBBM) and a porcine collagen membrane; Group 2: Socket Seal (SS) technique using DBBM and a porcine collagen matrix; Group 3: Unassisted socket healing (Control). Trephined bone biopsies were harvested following a 4-month healing period. Forty-two samples underwent Back-Scattered Electrons -Scanning Electron Microscopy (BSE-SEM) imaging, with 15 samples examined using Xray Micro-Tomography (XMT) (n = 6 for each GBR/SS and n = 3 Control). Images were analysed to determine the percentage (%) of connective tissue, new bone formation, residual DBBM particles and direct bone to DBBM particle contact (osseointegration).

Results

BSE-SEM analysis demonstrated that new bone formation was higher in the Control (45.89% ± 11.48) compared to both GBR (22.12% ± 12.7/p < .004) and SS (27.62% ± 17.76/p < .005) groups. The connective tissue percentage in GBR (49.72% ± 9), SS (47.81% ± 12.57) and Control (47.81% ± 12.57) groups was similar. GBR (28.17% ± 16.64) and SS (24.37% ± 18.61) groups had similar levels of residual DBBM particles. XMT volumetric analysis indicated a lower level of bone and DBBM particles in all test groups, when matched to the BSE-SEM area measurements. Osseointegration levels (DBBM graft and bone) were recorded at 35.66% (± 9.8) for GBR and 31.18% (± 19.38) for SS.

Conclusion

GBR and SS ARP techniques presented with less bone formation when compared to unassisted healing. GBR had more direct contact/osseointegration between the DBBM particles and newly formed bone.

目的研究牙槽嵴保留技术和无辅助牙槽窝愈合后的组织形态学骨组成：将 42 名需要单根拔牙的患者随机分为三组（每组 14 人）：第 1 组：使用脱蛋白牛骨矿物质（DBBM）和猪胶原蛋白膜的引导骨再生（GBR）；第 2 组：使用 DBBM 和猪胶原蛋白基质的牙槽密封（SS）技术；第 3 组：无辅助牙槽愈合（对照组）。在 4 个月的愈合期后采集畸形骨活检样本。42 个样本接受了背散射电子扫描电子显微镜（BSE-SEM）成像，15 个样本接受了 X 射线显微断层扫描（XMT）检查（GBR/SS 组各 6 个样本，对照组 3 个样本）。对图像进行分析，以确定结缔组织、新骨形成、残留 DBBM 颗粒和骨与 DBBM 颗粒直接接触（骨结合）的百分比（%）：结果：BSE-SEM 分析表明，与 GBR（22.12%±12.7/p）相比，对照组（45.89%±11.48）的新骨形成率更高：与非辅助愈合相比，GBR 和 SS ARP 技术的骨形成较少。GBR 在 DBBM 颗粒和新形成的骨之间有更多的直接接触/骨结合。

Objectives

The objective of this study is to assess accuracy, time-efficiency and consistency of a novel artificial intelligence (AI)-driven automated tool for cone-beam computed tomography (CBCT) and intraoral scan (IOS) registration compared with manual and semi-automated approaches.

Materials and Methods

A dataset of 31 intraoral scans (IOSs) and CBCT scans was used to validate automated IOS-CBCT registration (AR) when compared with manual (MR) and semi-automated registration (SR). CBCT scans were conducted by placing cotton rolls between the cheeks and teeth to facilitate gingival delineation. The time taken to perform multimodal registration was recorded in seconds. A qualitative analysis was carried out to assess the correspondence between hard and soft tissue anatomy on IOS and CBCT. In addition, a quantitative analysis was conducted by measuring median surface deviation (MSD) and root mean square (RMS) differences between registered IOSs.

Results

AR was the most time-efficient, taking 51.4 ± 17.2 s, compared with MR (840 ± 168.9 s) and SR approaches (274.7 ± 100.7 s). Both AR and SR resulted in significantly higher qualitative scores, favoring perfect IOS-CBCT registration, compared with MR (p = .001). Additionally, AR demonstrated significantly superior quantitative performance compared with SR, as indicated by low MSD (0.04 ± 0.07 mm) and RMS (0.19 ± 0.31 mm). In contrast, MR exhibited a significantly higher discrepancy compared with both AR (MSD = 0.13 ± 0.20 mm; RMS = 0.32 ± 0.14 mm) and SR (MSD = 0.11 ± 0.15 mm; RMS = 0.40 ± 0.30 mm).

Conclusions

The novel AI-driven method provided an accurate, time-efficient, and consistent multimodal IOS-CBCT registration, encompassing both soft and hard tissues. This approach stands as a valuable alternative to manual and semi-automated registration approaches in the presurgical implant planning workflow.

研究目的本研究旨在评估一种新型人工智能（AI）驱动的锥形束计算机断层扫描（CBCT）和口腔内扫描（IOS）自动配准工具与手动和半自动方法相比的准确性、时间效率和一致性：31个口内扫描（IOS）和CBCT扫描数据集用于验证IOS-CBCT自动配准（AR）与手动（MR）和半自动配准（SR）的比较。进行 CBCT 扫描时，在脸颊和牙齿之间放置棉卷，以方便划定牙龈。以秒为单位记录进行多模态配准所需的时间。我们进行了定性分析，以评估 IOS 和 CBCT 上硬组织和软组织解剖之间的对应关系。此外，还通过测量已登记 IOS 之间的中位表面偏差（MSD）和均方根差（RMS）进行了定量分析：结果：与 MR（840 ± 168.9 秒）和 SR（274.7 ± 100.7 秒）相比，AR 最省时，只需 51.4 ± 17.2 秒。与 MR 相比，AR 和 SR 的定性评分明显更高，更倾向于完美的 IOS-CBCT 配准（p = .001）。此外，AR 的定量性能明显优于 SR，表现为 MSD（0.04 ± 0.07 mm）和 RMS（0.19 ± 0.31 mm）较低。相比之下，MR 与 AR（MSD = 0.13 ± 0.20 mm；RMS = 0.32 ± 0.14 mm）和 SR（MSD = 0.11 ± 0.15 mm；RMS = 0.40 ± 0.30 mm）相比，差异明显更大：新颖的人工智能驱动方法提供了准确、省时和一致的多模态 IOS-CBCT 注册，包括软组织和硬组织。在术前种植规划工作流程中，这种方法是手动和半自动化配准方法的重要替代方案。

Objective

To compare fully guided flapless implant surgery using a light-cured surgical guide (FG group) with partially guided open flap surgery (PG group) in the posterior maxilla when performing simultaneous sinus floor elevation in terms of the accuracy, time requirements, and patient/clinician-reported outcomes (PROMs and CROMs).

Materials and Methods

In this study, 56 tissue-level implants were placed with crestal sinus floor elevation in 56 patients at single-tooth sites, with 28 implants allocated to the PG group and 28 to the FG group. The deviations of the placed implants from the virtually planned positions were measured at the implant platform and apex and for the angular deviation. The presurgical preparation time and the duration of surgery were measured. PROMs and CROMs were made by administering questionnaires at multiple time points.

Results

Horizontal deviations at the platform and apex and the angular deviation were significantly smaller in the FG group than the PG group (p < .05). Presurgical preparation and surgery times were significantly shorter in the FG group (p < .001). Patient satisfaction and willingness to receive repeat treatment were significantly better in the FG group than in the PG group (p < .005 and .025, respectively). Clinicians were more satisfied in the FG group than the PG group (p < .05).

Conclusion

When placing an implant with sinus floor elevation, the flapless approach using a fully guided surgical system can be more accurate, faster, and increase the satisfaction of both the clinician and patient compared to the partially guided surgery.

Objectives

The objective of this long-term retrospective study was to evaluate the fracture rate and the risk factors associated with the fracture of 3.3 mm narrow diameter implants (NDIs).

Materials and Methods

A total of 524 records of patients rehabilitated with 3.3 mm NDIs between 1997 and 2015 were assessed. Data on patients, implants, and prostheses were collected, and descriptive analysis of the variables was performed. NDIs were separated into 2 groups: “fractured” and “non-fractured”, and a multilevel logistic regression model was applied to identify the risk factors associated with NDI fracture.

Results

Eighty-four patients were removed from the analysis for interrupting follow-up or presenting failures other than fractures. Of the 440 patients included (64.66 ± 13.4 years), 272 were females (61.8%), and 168 males (38.2%), and mean follow-up time was 129 ± 47.1 months. Of the 1428 NDIs, 15 (1.05%) in 9 patients (2.04%) fractured during the studied period. Ten fractures (66.66%) happened in 6 patients (66.66%) showing signs of parafunction. NDI with modified sandblasted, large grit, acid-etched surface was the only implant variable to show a protective statistical significance (p = .0439).

Conclusions

NDI fracture was a rare event in the studied sample. NDIs manufactured with modified sandblasted, large grit, acid-etched surface may provide extra protection against NDI fracture. Patient-specific factors and implant characteristics should be carefully considered to limit the risk of fracture of 3.3 mm NDIs.

研究目的这项长期回顾性研究的目的是评估 3.3 毫米窄直径种植体（NDI）的骨折率以及与之相关的风险因素：评估了1997年至2015年间使用3.3毫米窄直径种植体进行康复治疗的524名患者的记录。收集了患者、种植体和修复体的数据，并对变量进行了描述性分析。NDI 被分为两组："应用多层次逻辑回归模型确定与NDI骨折相关的风险因素：84名患者因中断随访或出现骨折以外的其他故障而从分析中剔除。在纳入的 440 名患者（64.66 ± 13.4 岁）中，女性 272 名（61.8%），男性 168 名（38.2%），平均随访时间为 129 ± 47.1 个月。在 1428 例 NDI 中，有 9 名患者（2.04%）的 15 例（1.05%）在研究期间发生骨折。有 6 名患者（66.66%）的 10 处骨折（66.66%）显示出功能障碍的迹象。改良喷砂、大颗粒、酸蚀表面的 NDI 是唯一显示出保护性统计学意义（p = .0439）的种植体变量：结论：在所研究的样本中，NDI断裂的情况很少发生。采用改良喷砂、大颗粒、酸蚀表面制造的 NDI 可为防止 NDI 骨折提供额外保护。应仔细考虑患者的特定因素和植入物的特性，以限制 3.3 毫米 NDI 骨折的风险。
