Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:To investigate the clinical efficacy of percutaneous vertebral-disc plasty (PVDP) in the treatment of very severe osteoporotic vertebral compression fractures (vsOVCF).Methods:A total of 26 patients with vsOVCF were treated by PVDP at Department of Spine Surgery, The Second Affiliated Hospital, Nantong University from November 2019 to August 2021. They were 8 males and 18 females with an age of (77.9±5.2) years. Fracture sites: T11 in 9 cases, T12 in 13 cases, L1 in 7 cases, and L2 in 2 cases. The loss of vertebral height exceeded 2/3 of its original height. The curative effects were evaluated by comparing the visual analogue scale (VAS), Oswestry disability index (ODI) and local kyphosis angle (LKA) at preoperation, 1 day postoperation and the last follow-up.Results:This cohort was followed up for 12(10, 15) months. No obvious neurological damage or other serious complications occurred. The VAS scores [(2.9±0.7) and (2.2±0.7) points] and ODIs [28.0%±4.8% and 16.9%±4.0%] at 1 day postoperation and the final follow-up were significantly lower than the preoperative values respectively [(6.7±0.8) points and 66.7%±6.0%], and the values at the last follow-up were significantly lower than those at 1 day postoperation ( P<0.05). The LKAs at 1 day postoperation and the last follow-up (18.1°±4.1° and 19.5°±4.4°) were significantly smaller than that before operation (32.0°±5.2°) ( P<0.05), but there was no significant difference between 1 day postoperation and the last follow-up in LKA ( P>0.05). Conclusion:PVDP is an effective surgical treatment of vsOVCF, because it can relieve pain and improve local kyphosis with satisfactory clinical outcomes.

Objective:
To explore the early failure of narrow-diameter implants (NDIs) and to provide a reference for clinical implant restoration.
Methods:
From April 2017 to April 2020, data from a total of 725 patients (with 1 001 NDIs) who accepted implant restoration due to dentition defects were collected from the department of dental implantology in a stomatological hospital; 353 males and 372 females were included. The early failure rate of 1 001 NDIs was retrospectively analyzed. Univariate generalized estimated equation (GEE) and multivariate GEE were used to explore risk factors, including age, sex, implant location, materials, surface modification, length, bone augmentation and healing procedure, associated with early failure of NDIs.
Results:
There were 34 cases of early failure among 725 patients, including 38 NDIs. The early failure rate of NDIs was 4.69% at the patient level and 3.80% at the implant level. There was no significant difference in the early failure rate of NDIs among different age groups, sexes, implant materials, surface modifications, lengths, and healing procedures (P>0.05). Univariate analysis showed that there was a significant difference between the early failure rate of NDIs in the anterior maxilla group (2.16%) and the anterior mandible group (8.64%) at the implant level (P<0.001). However, there was no significant difference in the early failure rate between the anterior maxilla group and the posterior group (3.35%) (P>0.05). In addition, in the anterior region, the early failure rate of NDIs in the group with simultaneous bone augmentation was significantly lower than that of the group without bone augmentation (P<0.05). However, multivariate GEE analysis showed that the early failure rate of NDIs was only significantly positively correlated with implants in the mandibular anterior region (P<0.01).
Conclusion
The overall early survival rate of Straumann 3.3 mm NDIs is greater than 95%. The early failure of NDIs in the anterior mandible region is much higher than that in the anterior maxilla region and posterior region.

Objective:To investigate the influencing factors for prognoses of patients with high-grade aneurysmal subarachnoid hemorrhage (aSAH).Methods:A retrospective analysis was performed on clinical data of 104 patients with aSAH, admitted to our hospital from January 2012 to March 2010. According to the modified Rankin scale (mRS) scores 3 months after discharge, these patients were divided into good prognosis group (mRS scores≤2) and poor prognosis group (mRS scores >2). Clinical data of patients from the 2 groups were compared. Multivariate Logistic regression analysis was used to analyze the influencing factors for prognoses.Results:Forty patients (38.5%) were with good prognosis and 64 (61.5%) were with poor prognosis. As compared with patients in the poor prognosis group, patients in the good prognosis group had significantly lower proportion of patients>60 years old, and significantly lower Graeb scores, cast fourth ventricle (CFV) incidence, Fisher grading, blood glucose content, diastolic blood pressure, systolic blood pressure and mean arterial pressure, and statistically higher serum potassium content ( P<0.05). There were significant differences in treatment methods and incidence of complications between the two groups ( P<0.05). Multivariate Logistic regression analysis showed that age>60 years ( OR=13.470, 95%CI: 2.177-83.347, P=0.005), Fisher grading ( OR=6.649, 95%CI: 1.141-38.736, P=0.035), conservative treatment ( OR=6.348, 95%CI: 1.048-38.742, P=0.044), mean arterial pressure at admission ( OR=29.721, 95%CI: 3.177-278.012, P=0.003), serum potassium ( OR=5.296, 95%CI: 1.138-24.653, P=0.034), CFV ( OR=9.855, 95%CI: 1.785-51.456, P=0.008), and chronic hydrocephalus ( OR=19.298, 95%CI: 3.294-113.069, P=0.001) were influencing factors for prognoses of high-grade aSAH patients. Conclusion:Severe aSAH patients with advanced age, high Fisher grading, high mean arterial pressure, low serum potassium content, fourth ventricle casting and chronic hydrocephalus under conservative treatment are more likely to have poor prognosis.

Objective:To explore the influence of prognostic nutritional index (PNI) and controlling nutritional status (CONUT) on the prognosis of patients with multiple myeloma.Methods:Data of 157 patients with multiple myeloma (MM) at the affiliated hospital of Xuzhou medical university from January 2014 to December 2018 were retrospectively evaluated. The operating characteristic (ROC) curve analysis was adopted as the optimal cut-off point. PNI and CONUT were grouped based on the cut-off points of 44.45 and 3.5, respectively, and the differences between age, gender, serum calcium, β 2-microglobulin, serum creatinine, lactate dehydrogenase, and hemoglobin were analyzed. The prognostic factors were analyzed via univariate and Cox multivariate regression analyses. Results:The level of PNI and CONUT is the influencing factor of OS time. The univariate analysis revealed that age, LDH, plasma cell ratio, β 2-microglobulin, ISS stage, PNI, and CONUT were the risk factors for the prognosis of patients with MM. The multivariate analysis revealed that age ( HR=1.636, 95% CI 1.014-2.640) , plasma cell ratio ( HR=1.953, 95% CI 1.232-3.096) , and PNI ( HR=0.513, 95% CI 0.287-0.917) were the independent prognostic risk factors of patients with MM. Conclusion:Low PNI in patients with MM indicates a poor prognosis, which is an independent prognosis risk factor.

Objective:To understand the etiological characteristics of an acute gastroenteritis outbreak.Methods:Real-time polymerase chain reaction (PCR) and bacteria cultures were performed for the samples, including stool samples from patients and cooks, environmental swabs, raw food material (chicken meat), collected during the outbreak. Pulsed-field gel electrophoresis, antibiotics susceptibility test and whole-genome sequencing were performed for the Campylobacter jejuni isolates. Results:Four stool samples from patients were positive for Campylobacter jejuni by real-time PCR, in which 1 Campylobacter jejuni strain was isolated from a case who had no antibiotic treatment. Twelve Campylobacter jejuni and 7 Campylobacter coli isolates were obtained from 4 raw chicken meat samples. The Campylobacter jejuni strain isolated from the case was resistant to nalidixic acid, ciprofloxacin, chloramphenicol, florfenicol and tetracycline. The MLST analysis with the whole-genome sequences confirmed that the Campylobacter jejuni isolate from the case belonged to ST10075. Antimicrobial resistance genes cmeABCR, tetO/M and blaOXA-61 were found in the genome of the isolate from the patient by the whole-genome sequencing. No mutation in 23S rRNA was found and the C257T mutation in gyrA was identified in this isolate. Conclusion:Laboratory analysis indicated that Campylobacter jejuni infection might be the major cause of this gastroenteritis outbreak.

There were 24 cases with middle atresia and 64 cases with high atresia. All the cases were divided into 2 groups based on the operative method: laparoscopic group (laparoscopic?assisted anorectoplasty, 49 cases), pena group (posterior sagittal anorectoplasty, 39 cases). The demographic features of two groups were comparable. There were no statistically significant differences in gender, age, body mass, classification of anomaly types and sacral ratio (all P>0.05). Student t test and Chi square tests were used to compare the surgical conditions (operative time, postoperative hospital stay and complications), anal function (Kelly score), constipation (Krickenbeck constipation score) and anorectal pressure. Results Children of both groups all completed operation ssuccessfully. There were no statistically significant differences between laparoscopic group and pena group in the operative time [(120±31) minutes vs. (112±23) minutes, t=1.343, P=0.091] and postoperative hospital stay [(7.1±2.3) days vs. (10.7±3.3) days, t=6.021, P=1.000]. Complications were more common in the pena group [16.3% (8/49) vs. 35.9% (14/39), χ2=4.436, P=0.035]. The main complications in laparoscopic group were anal prolapse (8.2%, 4/49) and anal stenosis (6.2%, 3/49), while in pena group were anal stenosis (12.8%, 5/39) and perioperative perianal skin erosion (10.3%, 4/39). As for the anal function, the degree of feces, defecation control and sphincter contractility, the single scoring differences of Kelly scoring system were not statistically significant between the two groups, but the proportion of good function in the laparoscopic group was higher than that in the pena group [67.3% (8/49) vs. 38.5% (15/39), χ2=7.308, P=0.007]. Constipation occurred in 6 (12.2%) patients in the laparoscopic group, of whom 5 were improved by diet regulation and 1 required laxatives, while 9 (23.1%) patients developed constipation in the pena group, of whom 4 were improved by diet regulation and 5 required long?term laxatives. The difference of constipation ratio was not statistically significant (χ2=1.802, P=0.180). There were no cases of Krickenbeck constipation grade 3. Compared to the pena group, the laparoscopic group had higher anal resting pressure [(33.35 ± 9.69) mmHg vs. (27.68 ± 10.74) mmHg, t=2.599, P=0.011], higher dilating pressure [(9.00±5.61) mmHg vs.(6.51±3.24) mmHg, t=2.462, P=0.016], higher maximal squeeze pressure [(65.80 ± 17.23) mmHg vs. (56.74 ± 18.93) mmHg, t=2.389, P=0.019] and longer maximal contraction time [(21.16±5.02) seconds vs. (18.44±7.24) seconds, t=2.079, P=0.041]. The rectal resting pressure [(5.36 ± 3.00) mmHg vs. (4.61 ± 3.93) mmHg, t=1.015, P=0.312] was not statistically significantly different. Conclusions Compared with posterior sagittal anorectoplasty, laparoscopic?assisted anorectoplasty in the treatment of high and middle anal atresia has better long?term efficacy with less perioperative complications.
