    先前已经报道了将牙植入物放置在用于重建下颌骨或上颌骨的无微血管骨瓣中。然而,关于在旋髂深动脉(DCIA)微血管游离皮瓣中使用短牙科植入物的修复方案及其基本原理的信息很少.此病例报告描述了一名18岁的患者因左侧下颌骨麻木和隐痛而转诊到医院,她观察了三个月。由于下颌角左侧的“巨细胞病变”,该患者使用DCIA游离皮瓣进行了下颌骨切除和重建。在具有两个完整基牙冠的年轻患者中,放置了短的牙科植入物,并对切除中涉及的牙列进行了假体重建。短牙种植体的放置不会对游离皮瓣的血管蒂和活力产生负面影响。在我们的案例报告中,治愈两年后,DCIA皮瓣完成了出色的美学和功能,然后用短植入物修复。
    Placing dental implants in microvascular bone free flaps used for reconstructing the mandible or maxilla has been previously reported. However, there is scarce information available on the restorative protocol using short dental implants placed in a deep circumflex iliac artery (DCIA) microvascular free flap and the rationale behind it. This case report describes a 18-year-old patient referred to the hospital for numbness and dull pain of the left mandible, which she observed for three months. The patient underwent mandible resection and reconstruction using the DCIA free flap due to \"giant cell lesion\" on the left side of the mandibular angle. Short dental implants were placed and prosthetic reconstruction of the dentition involved in the resection was performed in a young patient with two integrated abutment crowns. The placement of short dental implants did not negatively affect the vascular pedicle and vitality of free flap. In our case report, two years after the healing, excellent aesthetic and function were accomplished with the DCIA flap followed by restoration with short implants.

    牙种植体骨折对长期治疗成功构成重大挑战。本系统综述旨在全面检查影响牙种植体骨折(IFs)的临床因素。此外,解决了选择正确类型的植入物和预防这种并发症的策略。在PubMed进行了系统的搜索,Scopus,和WebofScience数据库。符合条件的研究包括回顾性病例对照,前瞻性队列研究,和临床试验。最初的搜索产生了361篇文章,其中312项被排除在这些评论之外,病例报告,无关紧要,或用英语以外的其他语言写的。这留下了49篇文章,只有6人符合深入审查的资格标准。这些研究,所有回顾性病例对照,检查植入物特性,患者人口统计学,手术和假体变量,生物力学和功能因素,临床和程序变量,并发症和维护问题。使用ROBINS-I工具评估偏倚风险较低。主要研究结果表明,植入物直径和结构阻力之间存在相关性,更广泛的植入物显示骨折风险降低。此外,后部区域,尤其是磨牙和前磨牙,由于咀嚼力的增加,对IFs的敏感性更高。植入物的设计和材料可能会显著影响骨折风险,锥形植入物和螺钉保留假体显示出更高的脆弱性。生物力学过载,尤其是磨牙症患者,成为IFs的主要促成因素。假体类型显著影响骨折发生率,悬臂假体由于应力增加而带来更高的风险。种植体周围骨丢失与IFs密切相关,强调需要细致的术前评估和个性化管理策略。未来的研究应该优先考虑更大的和异质的群体与长期随访和标准化的方法,以提高结果的普遍性和可比性。在受控条件下进行随机对照试验和生物力学研究对于阐明导致IFs的复杂相互作用和制定有效的预防策略也至关重要。此外,整合患者报告的结局可以全面了解IFs对生活质量的影响.
    Dental implant fractures pose a significant challenge to long-term treatment success. This systematic review aims to comprehensively examine the clinical factors influencing dental implant fractures (IFs). Furthermore, strategies to choose the right type of implant and prevent this complication are addressed. A systematic search was conducted across PubMed, Scopus, and Web of Science databases. Eligible studies included retrospective case-control, prospective cohort studies, and clinical trials. The initial search yielded 361 articles, of which 312 were excluded being these reviews, case reports, irrelevant, or written in languages other than English. This left 49 articles, with only 6 meeting the eligibility criteria for an in-depth review. These studies, all retrospective case-control, examine implant characteristics, patient demographics, surgical and prosthetic variables, biomechanical and functional factors, clinical and procedural variables, complications and maintenance issues. The risk of bias was assessed as low using the ROBINS-I tool. Key findings suggest a correlation between implant diameter and structural resistance, with wider implants demonstrating reduced fracture risk. Additionally, posterior regions, especially molars and premolars, exhibit higher susceptibility to IFs due to increased masticatory forces. Implant design and material may considerably influence fracture risk, with conical implants and screw-retained prostheses showing higher vulnerability. Biomechanical overload, particularly in patients with bruxism, emerges as a primary contributing factor to IFs. Prosthesis type significantly influences fracture incidence, with cantilever prostheses posing a higher risk due to increased stress. Peri-implant bone loss is strongly associated with IFs, emphasizing the need for meticulous preoperative assessments and individualized management strategies. Future research should prioritize larger and heterogeneous populations with long-term follow-up and standardized methodologies to enhance the generalizability and comparability of findings. Randomized controlled trials and biomechanical studies under controlled conditions are also essential to elucidate the complex interactions contributing to IFs and developing effective prevention strategies. Additionally, integrating patient-reported outcomes may offer a comprehensive understanding of the impact of IFs on quality of life.

    使用牙科植入物对完全或部分无牙的患者进行康复是最常用的外科手术之一。Branemark的工作,观察到嵌入兔骨中的一块钛变得牢固附着且难以去除,介绍了骨整合的概念和革命性的现代牙科。从那以后,对改善植入材料以增强材料-组织整合的需求不断增长。人们坚信,纳米级材料将产生高效的下一代植入物,低成本,和高容量。这篇综述的目的是探讨纳米材料在植入学中的贡献。已经提出了多种纳米材料作为植入物表面定制的潜在候选者。它们可以具有固有的抗菌特性,为骨整合提供增强的条件,或充当生物分子和药物的储库。二氧化钛纳米管单独或与生物试剂或药物组合用于增强牙科植入物中的组织整合。关于免疫调节,为了避免植入物排斥,二氧化钛纳米管,石墨烯,石墨烯生物聚合物已经被成功利用,有时负载抗炎药和细胞外囊泡。可以通过金属纳米颗粒和壳聚糖或带有抗生素物质的混合涂层的固有抗菌特性来实现种植体周围炎的预防。为了改善耐腐蚀性,已经探索了各种材料。然而,尽管这些修改已经显示出了有希望的结果,未来的研究对于评估它们在人类中的临床行为并进行广泛的商业化是必要的。
    Rehabilitation of fully or partially edentulous patients with dental implants represents one of the most frequently used surgical procedures. The work of Branemark, who observed that a piece of titanium embedded in rabbit bone became firmly attached and difficult to remove, introduced the concept of osseointegration and revolutionized modern dentistry. Since then, an ever-growing need for improved implant materials towards enhanced material-tissue integration has emerged. There is a strong belief that nanoscale materials will produce a superior generation of implants with high efficiency, low cost, and high volume. The aim of this review is to explore the contribution of nanomaterials in implantology. A variety of nanomaterials have been proposed as potential candidates for implant surface customization. They can have inherent antibacterial properties, provide enhanced conditions for osseointegration, or act as reservoirs for biomolecules and drugs. Titania nanotubes alone or in combination with biological agents or drugs are used for enhanced tissue integration in dental implants. Regarding immunomodulation and in order to avoid implant rejection, titania nanotubes, graphene, and biopolymers have successfully been utilized, sometimes loaded with anti-inflammatory agents and extracellular vesicles. Peri-implantitis prevention can be achieved through the inherent antibacterial properties of metal nanoparticles and chitosan or hybrid coatings bearing antibiotic substances. For improved corrosion resistance various materials have been explored. However, even though these modifications have shown promising results, future research is necessary to assess their clinical behavior in humans and proceed to widespread commercialization.

    这项研究旨在从组织学上评估XPEED®和SLA表面对放置在人体骨骼中的钛牙植入物在3周和5周时的矿物质附着率(MAR)的影响。总的来说,本研究包括17个钛牙科植入物,其具有XPEED®表面(n=9)用作测试,SLA表面(n=8)用作对照。每个患者在活检前2周以12小时间隔接受四剂四环素500mg。进行了植入物取回,并在落射荧光显微镜下仔细处理并进行组织形态学评估。在3周和5周,新形成的骨出现与两种类型的测试表面直接接触。在3周,MAR值为,分别,XPEED®植入物为2.0(±0.18)μm/天,SLA植入物为1.5(±0.10)μm/天(p=0.017)。在5周,注意到XPEED®和SLA植入物的MAR值较低,1.2(±0.10)μm/天和1.1(±0.10)μm/天,分别(p=0.046)。通过线性回归分析对时间和植入物表面的总体评估显示,与3周相比,5周时的成骨细胞活性降低(p<0.005)。本研究的结果表明,在3周和5周愈合时,在具有XPEED®表面的植入物周围,骨并置速率发生得更快。MAR值可以支持在早期加载方案中使用具有XPEED®表面的植入物。
    This study aimed to histologically evaluate the effects of XPEED® and SLA surface on the mineral apposition rate (MAR) at 3 and 5 weeks in titanium dental implants placed in human bone. In total, 17 titanium dental implants with XPEED® surface (n = 9) used as test and SLA surface (n = 8) used as control were included in this study. Each patient received four doses of tetracycline 500 mg at 12 h intervals 2 weeks prior to biopsy retrieval. Implant retrieval was performed, and retrieved biopsies were carefully treated for histomorphometric evaluation under epifluorescence microscopy. At 3 and 5 weeks, newly formed bone appeared in direct contact with both types of tested surfaces. At 3 weeks, the MAR value was, respectively, 2.0 (±0.18) μm/day for XPEED® implants and 1.5 (±0.10) μm/day for SLA implants (p = 0.017). At 5 weeks, lower MAR values for both XPEED® and SLA implants were noted, with 1.2 (±0.10) μm/day and 1.1 (±0.10) μm/day, respectively (p = 0.046). The overall evaluation by linear regression analysis for both time and implant surfaces showed a decreased osteoblast activity at 5 weeks compared to 3 weeks (p < 0.005). The results of the present study show that the bone apposition rate occurs faster around implants with XPEED® surface at 3 weeks and 5 weeks of healing. MAR values may support the use of implants with XPEED® surfaces in early loading protocols.

    钛植入物通过表面碳氢化合物沉积经历老化过程,导致润湿性和生物活性降低。等离子体处理显着减少表面碳氢化合物,从而提高种植体的亲水性和增强骨整合过程。这项研究调查了等离子体表面处理对呈现纳米结构钙掺入表面(XPEED®)的植入物的骨与植入物接触(BIC)的影响。在随机对照试验(RCT)设计之后,在上颌骨后部接受植入物手术的患者接受了额外的等离子治疗(n=7)或未治疗(n=5)3.5×8mm植入物,这些植入物在4周的愈合期后进行组织学检查.组织形态分析显示,经等离子体处理的植入物表现出38.7%的BIC率,而未经处理的植入物为22.4%(p=0.002)。表明骨整合潜力增强。组织学图像还显示,与未处理的标本相比,等离子体处理的植入物周围的骨形成和成骨细胞活性增加。结果表明,等离子体处理提高了表面亲水性和生物响应,促进钛植入物周围的早期骨形成。这项研究强调了表面修饰在优化植入物整合中的重要性,并支持使用等离子体治疗来增强骨整合。从而改善植入物牙科的临床结果,并为即时和早期加载方案提供益处,特别是在软骨条件下。
    Titanium implants undergo an aging process through surface hydrocarbon deposition, resulting in decreased wettability and bioactivity. Plasma treatment was shown to significantly reduce surface hydrocarbons, thus improving implant hydrophilicity and enhancing the osseointegration process. This study investigates the effect of plasma surface treatment on bone-to-implant contact (BIC) of implants presenting a nanostructured calcium-incorporated surface (XPEED®). Following a Randomized Controlled Trial (RCT) design, patients undergoing implant surgery in the posterior maxilla received additional plasma-treated (n = 7) or -untreated (n = 5) 3.5 × 8 mm implants that were retrieved after a 4-week healing period for histological examination. Histomorphometric analysis showed that plasma-treated implants exhibited a 38.7% BIC rate compared to 22.4% of untreated implants (p = 0.002), indicating enhanced osseointegration potential. Histological images also revealed increased bone formation and active osteoblastic activity around plasma-treated implants when compared to untreated specimens. The findings suggest that plasma treatment improves surface hydrophilicity and biological response, facilitating early bone formation around titanium implants. This study underscores the importance of surface modifications in optimizing implant integration and supports the use of plasma treatment to enhance osseointegration, thereby improving clinical outcomes in implant dentistry and offering benefits for immediate and early loading protocols, particularly in soft bone conditions.

    目的:本研究旨在研究生物力学性能,细胞迁移,和无细胞真皮基质Epiflex的血运重建。作为一个去细胞,冻干人体皮肤移植物,Epiflex在医疗领域有着广泛的应用,特别是在种植和牙科。了解其生物力学特性对于其作为新型软组织移植物的临床应用至关重要。
    方法:将Epiflex(n=3)与来自身体供体(n=3)的腭组织进行比较。关键指标,如伸长率和抗撕裂性,被量化了。两种移植物都进行了组织学分析和扫描电子显微镜检查。此外,使用绒毛尿囊膜(CAM)测定评估Epiflex的愈合特性。
    结果:生物力学,Epiflex(平均值=116.01N)显示出比人pal组织(平均值=12.58N)承受更大的力(p=0.013)的能力。比较伸长率时,测量无显著差异(ASG平均值=9.93mm,EF平均值=9.7mm)。组织学上,Epiflex表现出松散连接的胶原纤维网络,上层致密。CAM测定表明有效的血运重建。
    结论:Epiflex似乎是软组织增强的可行选择,特别吸引那些由于道德或宗教原因而避免使用所有或特定动物衍生产品的患者群体。
    OBJECTIVE: This study aimed to investigate the biomechanical properties, cell migration, and revascularization of the acellular dermal matrix Epiflex. As a decellularized, freeze-dried human skin graft, Epiflex has broad applications in medical fields, particularly in implantology and dentistry. Understanding its biomechanical characteristics is crucial for its clinical adoption as a novel soft tissue graft option.
    METHODS: Epiflex (n = 3) was evaluated in comparison to palatal tissue from body donors (n = 3). Key metrics, such as elongation and tear resistance, were quantified. Both graft types underwent histological analysis and scanning electron microscopy. Additionally, the healing properties of Epiflex were assessed using a Chorioallantoic Membrane (CAM) Assay.
    RESULTS: Biomechanically, Epiflex (mean = 116.01 N) demonstrated the ability to withstand greater forces (p = 0.013) than human palatal tissue (mean = 12.58 N). When comparing the elongation, no significant difference was measured (ASG mean = 9.93 mm, EF mean = 9.7 mm). Histologically, Epiflex exhibited a loosely connected network of collagen fibers with a dense upper layer. The CAM Assay indicated efficient revascularization.
    CONCLUSIONS: Epiflex appears to be a viable option for soft tissue augmentation, particularly appealing to patient groups who avoid all or specific animal-derived products due to ethical or religious reasons.

    背景:植入物的有效放置关键取决于植入物与牙槽骨的骨结合水平。为了在植入过程中增加骨整合,研究集中在植入物的表面改性上,和形态学分析研究了与骨骼表面紧密相互作用的螺纹图案。
    目的:本研究旨在评估和比较不同表面修饰技术下口腔种植体骨整合的程度。
    方法:在本研究中,使用12只年龄为18-24个月的健康成年犬。在下颌骨的两侧进行拔牙,伤口用缝线缝合。两个月后,每只狗的右下颌骨接受局部麻醉和全身麻醉。根据其表面处理放置了四种不同的植入物类型:可吸收爆炸介质(RBM)处理的植入物,具有超薄HA膜的羟基磷灰石(HA)植入物,用HA涂覆的水热处理的HA植入物,用等离子喷涂和酸蚀刻处理的喷砂联合酸蚀刻(SLA)植入物。总共48个植入物被分为两周和四周组,具有相同的尺寸。每只狗接受两组植入物,每只狗总共植入八个植入物。将植入物以大于35-N的扭矩牢固地放置在上牙槽骨中,直到深度为1mm。PeriotestM(MedizintechnikGuldene.K.,Modautal,Germany)用于在放置和处死后立即计算每个植入物的颊侧的典型值,以测试植入物的主要固定和稳定性。OsstellMentor(OsstellAB,哥德堡,瑞典)同时评估内侧的植入物稳定性商(ISQ),远端,颊,和植入物的舌侧。使用MGT50(ELECTROMATICEquipmentCo.,Inc.,纽约,美国)扭矩分析仪。使用光学显微镜(OlympusCorporation,东京,日本)。上半部的骨-种植体接触(BIC),这对植入物的稳定性更重要,研究了新骨形成面积(NBFA)与完整植入物的比率。
    结果:在第四周,在HA处理的植入物中观察到最大的稳定性。在第四周在水热处理的HA植入物中观察到最小的稳定性。与两周评估相比,在四周评估中每组的稳定性更大。在两周和三周的评价中,几乎所有植入物的稳定性都是令人满意的。在HA处理的植入物中观察到在两周和四周评估时新形成的骨的百分比面积的最大值。分别在SLA和RBM处理的植入物中观察到在两周和四周评估时新形成的骨的面积百分比的最小值。差异有统计学意义(p≤0.05)。
    结论:所有植入物表面改性,总的来说,产生令人满意的骨整合。在具有水热处理的HA的植入物的上部观察到优异的骨整合。
    BACKGROUND: Effective implant placement depends critically on the implant\'s level of osseointegration with the alveolar bone. To increase osseointegration during implant placement, research has concentrated on the surface modification of implants, and morphological analyses have looked at the thread pattern in close interaction with the bone\'s surface.
    OBJECTIVE: This study aimed to assess and compare the extent of oral implant osseointegration in different surface modification techniques.
    METHODS: In this study, 12 healthy adult dogs aged 18-24 months were used. Tooth extractions were performed on both sides of the mandible, and wounds were closed with sutures. Two months later, the right mandible of each dog underwent local anesthesia and general anesthesia. Four different implant types were placed based on their surface treatments: resorbable blast media (RBM)-treated implants, hydroxyapatite (HA) implants with an ultra-thin HA film, hydrothermal-treated HA implants coated with HA, and sandblasting combined acid etching (SLA) implants treated with plasma spray and acid etching. A total of 48 implants were divided into two- and four-week groups, with identical dimensions. Each dog received two implants from each group, for a total of eight implants per dog. The implants were securely placed into the superior alveolar bone with a torque greater than 35-N up to a depth of 1 mm. Periotest M (Medizintechnik Gulden e.K., Modautal, Germany) was used to calculate the periotest value (PTV) as a typical value on the buccal side of each implant immediately following placement and sacrifice to test the main fixation and stability of the implants. Resonance frequency analysis (RFA) was utilised by Osstell Mentor (Osstell AB, Gothenburg, Sweden) to simultaneously assess the implant stability quotient (ISQ) on the medial, distal, buccal, and lingual sides of the implant. The rotational torque in one of the sacrificed dogs was calculated using the MGT 50 (ELECTROMATIC Equipment Co., Inc., New York, USA) torque analyzer. The histomorphometric evaluation was performed using an optical microscope (Olympus Corporation, Tokyo, Japan). The upper half\'s bone-implant contact (BIC), which was found to be more important for implant stability, was studied together with the ratio of the new bone formation area (NBFA) to the complete implant.
    RESULTS: The maximum stability was observed in HA-treated implants in the fourth week. The minimum stability was observed in hydrothermal-treated HA implants in the fourth week. The stability in each group was greater in the four-week evaluation as compared to the two-week evaluation. The stability was satisfactory in almost all implants at two- and three-week evaluations. The maximum value of the percentage area of newly formed bone at the two- and four-week evaluations was observed in HA-treated implants. The minimum value of the percentage of the area of newly formed bone at two- and four-week evaluations was observed in SLA and RBM-treated implants respectively. The difference was significant statistically (p ≤ 0.05).
    CONCLUSIONS: All implant surface modifications, in general, produced satisfactory osseointegration. Excellent osseointegration was seen in the upper portion of the implant with hydrothermally treated HA.
