Objectives: To in vitro investigate the effect of different implant surface decontamination methods and treatment storing conditions on implant surface morphology and cell viability.

Materials and methods: Titanium disks with a sand-blasted and acid-etched surface (Promote, PRO) were treated with diamond polishing brushes (BRUSH), nickel-titanium brushes (NITI), or phenol and sulfuric acid-gel (GEL). The disks were stored in saline (-S) or left exposed to air overnight (-A). Untreated (PRO) and machined (MACHINED) disks were used as controls. GEL samples were treated for the 60 s, while the operative time was recorded for BRUSH and NITI. The samples were subjected to scanning electron microscopy (SEM), surface roughness measurements, and cell viability (SaOS-2 cells, 7 days) assessment.

Results: The operative time was shorter for NITI than for BRUSH (p = 0.017). The original surface morphology (PRO) was not altered in the GEL group, in contrast with what was observed for BRUSH and NITI. The type of storage did not influence the surface morphology. No significant differences in Sa and Sz were observed among the groups, except for MACHINED, which presented lower Sa values (p < 0.05). Cells were able to proliferate on all surfaces. NITI-S showed significantly higher cell viability compared to all groups (p ≤ 0.001), except for NITI-A and MACHINED. Among the treated groups, only one additional significant difference was found, as NITI-A performed better than GEL-S.

Conclusions: None of the investigated protocols compromised the cytocompatibility of the titanium dental implant surface. The best results were registered in the NITI group when the samples were stored in saline. Future studies should confirm the effectiveness of the proposed methods in removing bacterial biofilm from contaminated implant surfaces.

目的:体外研究不同种植体表面净化方法和处理储存条件对种植体表面形态和细胞活力的影响:体外研究不同种植体表面去污方法和处理储存条件对种植体表面形态和细胞活力的影响:用金刚石抛光刷(BRUSH)、镍钛刷(NITI)或苯酚和硫酸凝胶(GEL)对表面喷砂和酸蚀的钛盘(Promote,PRO)进行处理。磁盘储存在生理盐水中(-S)或暴露在空气中过夜(-A)。未经处理(PRO)和机加工(MACHINED)的磁盘用作对照组。GEL 样品的处理时间为 60 秒,而 BRUSH 和 NITI 则记录了操作时间。对样品进行扫描电子显微镜(SEM)、表面粗糙度测量和细胞存活率(SaOS-2 细胞,7 天)评估:结果:NITI 的手术时间比 BRUSH 短(p = 0.017)。GEL 组的原始表面形态(PRO)没有改变,这与 BRUSH 和 NITI 观察到的情况相反。储存类型对表面形态没有影响。除 MACHINED 组的 Sa 值较低外,其他各组的 Sa 和 Sz 均无明显差异(p 结论):所有研究方案都不会影响钛种植体表面的细胞相容性。将样本保存在生理盐水中时,NITI 组的结果最好。未来的研究应确认所建议的方法在清除受污染种植体表面的细菌生物膜方面的有效性。

Objectives: This in vitro study compared the accuracy of conventional impressions (CNVs), photogrammetry (PG), and intraoral scanning (IOS) for recording implant impressions of edentulous segments, ranging from part to complete arches by different evaluation methods.

Methods: The master model for an edentulous maxillary arch was created with six implants (a-f). CNVs, PG, and IOS were used for impressions. Three impression ranges (bcde, bcdef, and abcdef) were chosen for analysis. The best-fit algorithm, absolute linear deviation, and angular deviation were used for evaluation. Trueness and precision were analyzed by two-way ANOVA and the Kruskal-Wallis test, respectively.

Results: The accuracy of multiple implant impressions was significantly influenced by the impression method and impression range (p < 0.05) regardless of the evaluation methods used. At smaller ranges (bcde and bcdef), there was no difference in the trueness of the three impression methods, whereas at a larger range (abcdef), both PG and CNV exhibited similar trueness, which was significantly higher than that of IOS(p < 0.05). The precision of PG was significantly better than that of CNV and IOS in most of cases (p < 0.05). As the range expanded, the trueness and precision of PG and IOS decreased (p < 0.05), whereas the accuracy of CNV remained stable.

Conclusions: In the case of large-range impressions, PG demonstrated a similar degree of trueness and better precision compared with CNVs, whereas the trueness and precision of the intraoral scanning were worse. This indicated that PG might be a promising method for multiple implant impressions.

研究目的这项体外研究比较了传统印模(CNV)、摄影测量(PG)和口内扫描(IOS)通过不同的评估方法记录无牙颌部分(从部分牙弓到完整牙弓)种植体印模的准确性:方法: 使用六颗种植体(a-f)制作上颌无牙弓的主模型。使用 CNV、PG 和 IOS 进行印模。选择三个印模范围(bcde、bcdef 和 abcdef)进行分析。使用最佳拟合算法、绝对线性偏差和角度偏差进行评估。真实度和精确度分别通过双向方差分析和 Kruskal-Wallis 检验进行分析:结果:多颗种植体印模的精确度受印模方法和印模范围的显著影响(p 结论:印模范围越大,精确度越高:在大范围印模中,PG 与 CNV 相比,显示出相似的真实度和更好的精确度,而口内扫描的真实度和精确度较差。这表明 PG 可能是一种很有前途的多种植体印模方法。

Introduction: Using mini implants as transitional implants (TIs) for complete arch implant-supported rehabilitations may overcome limitations associated with mucosa-supported surgical guides and facilitate immediate fixed provisionalization. This study aimed to assess the success of TIs in supporting surgical guides for implant placement and fixed provisional prostheses.

Methods: Patients who received TIs between 2012 and 2023 for a complete arch implant-supported prosthesis were evaluated retrospectively. Patient demographic data, TI functionality in supporting a surgical guide and supporting a complete arch provisional prosthesis, and dates of TI placement and regular implant placement were collected. Descriptive statistics were used to determine the survival rate and success rate for TIs.

Results: Twenty-six patients, 35 jaws, 136 TIs, and 216 regular implants were included. The survival rate of TIs was 74.26%; however, the use of TIs yielded success in 97% of jaws for supporting a surgical guide and a fixed complete-arch provisional prosthesis throughout the complete provisional phase. An average of 4 TIs per maxilla and 3 TIs per mandible supported surgical guides. Thirty-five provisional prostheses were placed on an average of 4 TIs in the maxilla and 3 TIs in the mandible. Thirty-four provisional prostheses were successfully supported by TIs and regular implants until final restoration delivery. The survival of regular implants placed in conjunction with the use of TIs was 98%.

Conclusions: Using TIs to support a surgical guide and provisional prosthesis may be a predictable approach with a high success rate. All surgical guides planned to be supported on TIs were successful. Despite premature loss or replacement of TIs, this approach was able to support most provisional prostheses until the regular implants could be loaded.

导言:使用微型种植体作为过渡性种植体(TI)进行全弓种植体支持修复,可以克服粘膜支持手术导板的局限性,并促进即刻固定临时修复。本研究旨在评估TI在支持种植体植入手术导板和固定临时修复体方面的成功率:方法: 对2012年至2023年期间接受TI进行全弓种植义齿修复的患者进行回顾性评估。收集了患者的人口统计学数据、TI在支持手术导板和支持全弓临时修复体方面的功能、TI植入日期和常规种植体植入日期。描述性统计用于确定TI的存活率和成功率:共纳入 26 名患者、35 个颌骨、136 个 TI 和 216 个常规种植体。TIs的存活率为74.26%;然而,在整个临时阶段,97%的颌骨使用TIs成功地支撑了手术导板和固定全拱临时假体。平均每个上颌有 4 个 TI,每个下颌有 3 个 TI 支持手术导板。平均每个上颌骨有4个TI,下颌骨有3个TI,共安装了35颗临时义齿。34颗临时义齿成功地得到了TI和常规种植体的支持,直至最终修复体植入。在使用TI的同时植入的常规种植体的存活率为98%:结论:使用 TI 支持手术导板和临时修复体可能是一种成功率较高的可预测方法。所有计划用TI支撑的手术导板都获得了成功。尽管TI过早丢失或更换,但这种方法仍能支持大多数临时假体,直到常规种植体可以装入。

Aim: To report the 10-year clinical and radiographic outcomes of implants placed in grafted (GBR) and non-grafted (no-GBR) sites in a Swiss specialist private practice using hydrophilic implants with a low surface roughness flange.

Methods: Fifty consecutively enrolled patients received 159 hydrophilic implants with a low surface roughness flange. A first re-evaluation was performed 1 year after delivery of restoration (T1). An additional examination was performed at the 10-year follow-up (T2) including the assessment of clinical (i.e., periodontal/peri-implant pockets probing depths (PPD) (mm), full-mouth bleeding score (%), implant survival rate, mid-buccal keratinized mucosa (KM) width in mm, and peri-implant phenotype), and radiographic (i.e., marginal bone level change [ΔMBL]) outcomes. Biological, mechanical and technical complications were also recorded.

Results: Out of the initial cohort, 22 patients (9/40.9% male and 13/59% female) and 63 implants (47 with GBR, 16 without GBR), could be re-examined at T2. Overall, ΔMBL (T2-T1) was -0.56 ± 0.96 mm. In the GBR group, ΔMBL were significantly higher at the distal sites compared to the no-GBR group (-0.75 ± 1.17 mm vs. -0.12 ± 1.29 mm, p = 0.045), however, in the GBR group MBL started at a higher level at T1 but were similar with the no-GBR group at T2. Implant survival was 100% with only very few technical complications (6.3%). Mean PPD amounted to 3.84 ± 1.00 mm with significantly higher values in the GBR group (3.98 ± 1.08 mm vs. 3.45 ± 0.60 mm; p = 0.016). Nineteen implants (30.1%) were diagnosed with peri-implant health while 44 (69.9%) presented with peri-implant mucositis.

Conclusion: Within the limitations of this study, favorable clinical and radiographic conditions were recorded around hydrophilic implants with a low surface roughness flange placed in pristine and augmented bone after 10 years in function.

目的:报告瑞士一家私人专科诊所使用表面粗糙度较低的亲水性凸缘种植体,在移植(GBR)和非移植(no-GBR)部位植入种植体的 10 年临床和放射学结果:50 名连续登记的患者接受了 159 个带有低表面粗糙度凸缘的亲水种植体。修复体交付 1 年后进行了第一次重新评估(T1)。10年随访(T2)时再进行一次检查,包括临床(即牙周/种植体周围探诊深度(PPD)(毫米)、全口出血评分(%)、种植体存活率、颊中角化粘膜(KM)宽度(毫米)和种植体周围表型)和影像学(即边缘骨水平变化[ΔMBL])结果评估。此外,还记录了生物、机械和技术并发症:在首批患者中,有22名患者(9/40.9%为男性,13/59%为女性)和63颗种植体(47颗有GBR,16颗无GBR)可以在T2期进行复查。总体而言,ΔMBL(T2-T1)为-0.56 ± 0.96 mm。在 GBR 组中,远端部位的 ΔMBL 明显高于无 GBR 组(-0.75 ± 1.17 mm vs. -0.12 ± 1.29 mm,p = 0.045),但 GBR 组在 T1 阶段的 MBL 水平较高,但在 T2 阶段与无 GBR 组相似。种植体存活率为 100%,只有极少数技术并发症(6.3%)。平均 PPD 为 3.84 ± 1.00 mm,GBR 组的数值明显更高(3.98 ± 1.08 mm vs. 3.45 ± 0.60 mm; p = 0.016)。19颗种植体(30.1%)被诊断为种植体周围健康,44颗种植体(69.9%)出现种植体周围粘膜炎:在本研究的限制条件下,在原始骨质和增量骨质中植入低表面粗糙度凸缘的亲水性种植体10年后,其临床和放射学状况良好。

Aim: To investigate the influence of lateral hard-tissue grafting performed simultaneously to implant placement on peri-implant health or disease.

Materials and methods: A total of 299 patients exhibiting 897 implants placed either simultaneously with lateral bone grafting using a bovine bone mineral with or without adjunctive native collagen membrane (n = 131/269 patients/implants; LatGr group) or at pristine bone sites without lateral bone grafting (n = 168/628 patients/implants; NoGr group) were enrolled in this cross-sectional analysis. Clinical outcomes (i.e., modified plaque index (mPI), bleeding on probing (BOP), probing depth (PD), mucosal recession (MR)), keratinized mucosa (KM), and the frequency of peri-implant disease were evaluated. Univariate and multiple ordinal regression analyses with mixed effects were conducted to identify factors associated with peri-implant disease.

Results: After a mean follow-up period of 59.47 ± 24.66 months, mPI, BOP, and KM values were significantly higher in the control group, whereas no difference between the groups was found for PD and MR. Peri-implantitis was diagnosed in 31.30% of patients and 13.4% of implants in the LatGr group, and in 32.74% of patients and 24.8% of implants in the NoGr group. The corresponding values for peri-implant mucositis at the patient and implant level in the LatGr and NoGr groups were 29.77% and 29.0%, and 26.19% and 28.5%, respectively. Implants of the LatGr group were associated with a significantly lower chance to be affected by peri-implant disease (OR = 0.69, 95%-CI: (-0.72, -0.03), p = 0.032). The presence of plaque at implant sites and smoking significantly correlated with peri-implant disease (OR = 2.92, 95%-CI: (2.11, 4.03), p < 0.001 and OR = 0.22; 95%-CI: (0.06, 0.84), p = 0.027, respectively).

Conclusions: Lateral hard-tissue grafting performed simultaneously with implant placement demonstrated comparable peri-implant tissue health to pristine bone sites without lateral bone grafting.

目的:研究在植入种植体的同时进行侧向硬组织移植对种植体周围健康或疾病的影响:本横断面分析共纳入了 299 名患者的 897 颗种植体,这些种植体有的使用牛骨矿物质进行侧向骨移植,同时使用或不使用原生胶原膜(n = 131/269 例患者/种植体;LatGr 组),有的则在原始骨部位进行侧向骨移植,但未进行侧向骨移植(n = 168/628 例患者/种植体;NoGr 组)。对临床结果(即改良牙菌斑指数(mPI)、探诊出血量(BOP)、探诊深度(PD)、粘膜萎缩(MR))、角化粘膜(KM)和种植体周围疾病的频率进行了评估。采用混合效应进行单变量和多元序数回归分析,以确定与种植体周围疾病相关的因素:平均随访时间为(59.47 ± 24.66)个月后,对照组的 mPI、BOP 和 KM 值明显高于对照组,而 PD 和 MR 在组间无差异。LatGr 组有 31.30% 的患者和 13.4% 的种植体被诊断出种植体周围炎,NoGr 组有 32.74% 的患者和 24.8% 的种植体被诊断出种植体周围炎。LatGr 组和 NoGr 组患者和种植体水平的种植体周围粘膜炎相应值分别为 29.77% 和 29.0%,以及 26.19% 和 28.5%。LatGr 组种植体患种植体周围疾病的几率明显较低(OR = 0.69,95%-CI:(-0.72, -0.03),P = 0.032)。种植部位存在牙菌斑和吸烟与种植体周围疾病有显著相关性(OR = 2.92,95%-CI:(2.11,4.03),p 结论:种植体周围疾病与种植体周围硬组织移植有显著相关性:与种植体植入同时进行的侧向硬组织移植与未进行侧向骨移植的原始骨部位相比,种植体周围组织的健康状况相当。

Introduction: Implantoplasty can be performed on implants diagnosed with peri-implantitis to facilitate implant decontamination and improve access for oral home care. However, its effect on the mechanical strength of the implant is still uncertain. This study aimed to evaluate the effect of implantoplasty on the fracture resistance of dental implants with various degrees of bone loss, as well as its surface changes.

Methods: Eighty 4.2 × 13 mm conical connection dental implants were allocated evenly into four groups based on the bone defect morphology: circumferential or semi-circumferential, and 3 or 5 mm vertical height. Half of the implants underwent implantoplasty with tungsten carbide finishing burs. Weight, volume, and surface roughness of the implants were recorded prior to and after instrumentation. All implants were subjected to static loading to failure or fracture and the implant surfaces were then analyzed using optical microscopy. Finite element analysis was carried out to assess the stress pattern on dental implants after implantoplasty.

Results: Implantoplasty significantly reduced the fracture resistance of implants with all defect morphologies, aside from those with 3 mm of circumferential bone loss. Implants with 5 mm of peri-implant bone loss also experienced significantly reduced fracture resistance compared to the 3 mm group. Significant decrease in fracture resistance was only observed between the circumferential and semi-circumferential groups with 5 mm of bone loss. Surface roughness was also significantly reduced following implantoplasty. The results from finite element analysis revealed a change in pattern of stress concentration in the implant after implantoplasty.

Conclusion: Implantoplasty negatively impacted the fracture resistance of standard diameter dental implants in most scenarios. The increase in exposed implant length resulted in a decrease in fracture resistance. This increase in fracture risk should be considered prior to implantoplasty, especially in implants with more advanced bone loss.

导言:种植体植入术可用于诊断为种植体周围炎的种植体,以促进种植体净化,改善口腔家庭护理的可及性。然而,其对种植体机械强度的影响仍不确定。本研究旨在评估种植体成形术对不同程度骨质流失的牙科种植体的抗折性及其表面变化的影响:方法:根据骨缺损形态将 80 颗 4.2 × 13 毫米的锥形连接种植体平均分为四组:环形或半环形,垂直高度为 3 毫米或 5 毫米。半数种植体使用碳化钨精加工车针进行种植整形。在植入前和植入后,对种植体的重量、体积和表面粗糙度进行了记录。对所有种植体进行静态加载,直至失效或断裂,然后使用光学显微镜对种植体表面进行分析。此外,还进行了有限元分析,以评估种植整形术后牙科种植体的应力模式:结果:种植体植入术明显降低了所有缺损形态种植体的抗折性,只有周缘骨缺失 3 毫米的种植体除外。与 3 毫米组相比,种植体周围骨质流失 5 毫米的种植体的抗折性也明显降低。只有周缘骨质缺失 5 毫米组和半周缘骨质缺失 5 毫米组之间的抗折性才会显著降低。种植体植入后,表面粗糙度也明显降低。有限元分析的结果表明,种植体植入术后种植体的应力集中模式发生了变化:结论:在大多数情况下,种植体植入术对标准直径牙科种植体的抗折性产生了负面影响。种植体暴露长度的增加导致抗折性降低。在进行种植手术前应考虑到骨折风险的增加,尤其是骨质流失较严重的种植体。

Introduction: This study aimed to analyze the factors affecting the occurrence of peri-implant medication-related osteonecrosis of the jaw (PI-MRONJ) in patients using anti-resorptive drugs (ARDs) on different implant position, inclinations, and types of prosthesis.

Methods: The data of 75 patients with bone necrosis that progressed around the implant between 2018 and 2022 were retrospectively examined to identify the factors influencing PI-MRONJ. Data, including patient demographics (age, sex, smoking status, concomitant disease, time of ARD therapy, dose of ARDs, and parafunctional habits) and implant-specific information (type of prosthesis, angle of insertion), were extracted from medical and dental records.

Results: Tilted implants with an angle ≥ 5.1° relative to the occlusal plane of the prosthesis had a stronger association with PI-MRONJ in comparison to non-tilted implants (inclination was < 5°). Additionally, the boundary of the area of osteonecrosis around the fixture was larger for the splinted implant-supported crowns than for the single implant supported crowns).

Conclusion: In patients taking anti-resorptive medications the inclination of the implant was associated with the occurrence of PI-MRONJ. Further studies are required to confirm the clinical findings.

<p><strong>Background: </strong>Dental implants made of zirconia (ZrO<sub>2</sub>) are a potential alternative for titanium implants in dentistry because of their good biocompatibility, mechanical properties and excellent aesthetic results.

No significant differences in survival rate were found after stratification on "manipulation of the implant" and on "occlusal scheme." Mean bone-level alteration between baseline and the first follow-up was +0.06 mm (95% CI [-0.23 mm; 0.12 mm]; SD = 0.42 mm) and between baseline and the second follow-up was +0.04 mm (95% CI [-0.35 mm; 0.26 mm]; SD = 0.54 mm). Patients' satisfaction for patients with implants still in function after 5 years was 91.7% (IQR = [90.5%-97.3%]), indicating satisfaction with the treatment.

背景:氧化锆(ZrO2)牙科种植体因其良好的生物相容性、机械性能和出色的美观效果,成为牙科领域钛种植体的潜在替代品。目的:本研究旨在描述和检查定制的两件式氧化锆种植体的临床表现,确定可能的影响因素:a)种植体植入后的操作;b)咬合方案对成活率的影响,并评估种植体支撑的牙冠的表现。这项跟踪研究收集并检查了 5 年的数据,以回答主要问题:上颌前磨牙区定制二氧化锆种植体5年后的存活率和成功率如何?在这项为期5年的前瞻性单臂随访临床试验的31名患者中,有30人接受了定制的ZrO2种植体,以替代缺失的单颗上颌前磨牙,随后用二硅酸锂冠进行修复。临床表现、边缘骨水平(MBL)变化和患者相关结果指标(PROMs)等参数在术前、基线、牙冠植入后 1 年和 5 年进行了评估。使用 Kaplan-Meier 统计法计算并显示种植体的存活率和成功率。卡普兰-梅耶生存率分析还根据 "取印模前对种植体的操作 "和 "咬合方案 "这两个变量进行分层,并使用对数秩检验进行比较。使用配对样本 t 检验比较了骨水平在时间上的调节作用。使用 Wilcoxon 符号秩检验比较了患者的期望值和 5 年后的满意度,以衡量期望值是否实现。种植体支撑牙冠的性能采用已验证的标准进行评估:结果:定制 ZV3 种植体 5 年后的存活率和成功率分别为 75.8%(95% CI [60.0%; 91.0%])和 71.0%(95% CI [54.0%; 88.0%])。根据 "种植体操作 "和 "咬合方案 "进行分层后,存活率没有发现明显差异。基线与第一次随访之间的平均骨水平变化为 +0.06 mm (95% CI [-0.23 mm; 0.12 mm]; SD = 0.42 mm),基线与第二次随访之间的平均骨水平变化为 +0.04 mm (95% CI [-0.35 mm; 0.26 mm]; SD = 0.54 mm)。种植体在 5 年后仍能发挥作用的患者的满意度为 91.7%(IQR = [90.5%-97.3%]),表明患者对治疗感到满意。5 年后成功植入种植体的患者的总体满意度明显高于患者在治疗前表达的期望值。没有一个牙冠失败,也不需要任何干预措施:结论和临床意义:在我们的研究中,ZV3种植体的存活率低于预期,临床上无法接受。因此,本研究中应用的 ZV3 种植体不能推荐用于临床实践。强烈建议在进行更大规模的前瞻性随机临床试验以评估定制的二氧化锆种植体的治疗前,对二氧化锆种植体机械故障的不同表现形式进行进一步研究。

Background: Full-arch immediate loading rehabilitations are now a widely used rehabilitation method that guarantees predictable medium- and long-term results. Numerous factors can influence its success and stability in the medium and long term. Among these the implant-abutment connection seems to play an important role, however there is still little information on which is the most suitable in this type of treatment.

Purpose: The aim of the present multicenter split-mouth controlled trial is to evaluate whether external hexagonal connections (EHC) and internal hexagonal connections (IHC) can influence success, bone resorption and peri-implant parameters in immediate-load full-arch rehabilitations.

Materials and methods: Twenty patients were rehabilitated with immediately loaded fixed full-arch rehabilitations. All the implants presented the same macro- and micro-topography but different implant-abutment connection. IHC were used in one randomly selected side of the jaw and EHC was used in the other side. Outcome measures were implant survival rate, peri-implant marginal bone loss (MBL), plaque index (PI), probing depth (PD), and bleeding on probing (BoP) evaluated at 3, 6, 12, 36, and 72-month post-loading. Technical and biological complications were recorded.

Results: In 20 patients, 43 EHC and 40 IHC implants were placed. Between 32 and 72 months of follow-up two patients withdrew (died) and no implants were lost. The cumulative survival rate (CSR) was 97.44% for EHC implants and 97.22% for IHC implants. The MBL presented a resorption of 2 mm in the EHC group and 1.9 mm in the IHC group. No statistically significant differences were found between the two groups for any of the parameters at any time. No biological or technical complications were detected between the 36th and 72nd month of follow-up.

Conclusions: After 72 months in function, both internal and external hexagon connections provided good clinical outcomes and were not associated with any significant difference in the clinical outcomes.

背景:全弓即刻加载康复是目前广泛使用的一种康复方法,它能保证可预测的中长期效果。影响中长期效果和稳定性的因素有很多。目的:本多中心分口对照试验的目的是评估外六方连接(EHC)和内六角连接(IHC)是否会影响即刻加载全牙弓修复的成功率、骨吸收和种植体周围参数:对 20 名患者进行了即刻加载固定全牙弓修复。所有种植体的宏观和微观形态相同,但种植体与基台的连接方式不同。随机选择一侧下颌使用 IHC,另一侧下颌使用 EHC。结果测量指标包括种植体成活率、种植体周围边缘骨缺损(MBL)、牙菌斑指数(PI)、探诊深度(PD)和探诊出血量(BoP),分别在种植体植入后 3、6、12、36 和 72 个月进行评估。记录了技术和生物学并发症:在20名患者中,植入了43颗EHC种植体和40颗IHC种植体。在 32 到 72 个月的随访期间,两名患者退出(死亡),没有种植体丢失。EHC 种植体的累积存活率为 97.44%,IHC 种植体的累积存活率为 97.22%。EHC 组的 MBL 吸收了 2 毫米,IHC 组的 MBL 吸收了 1.9 毫米。两组在任何时间的任何参数上都没有发现明显的统计学差异。在随访的第36个月至第72个月期间,未发现生物学或技术上的并发症:经过72个月的功能锻炼后,内六角和外六角连接都能提供良好的临床效果,并且在临床效果方面没有任何明显差异。

Numerous factors can influence its success and stability in the medium and long term.

All the implants presented the same macro- and micro-topography but different implant-abutment connection. IHC were used in one randomly selected side of the jaw and EHC was used in the other side.
