Purpose: There is a growing pressure in implant dentistry to perform implant rehabilitations in difficult conditions, such as fresh extraction sockets, periodontally compromised sites, or sites with low bone density and quantity that imply a high likelihood of dehiscences or fenestrations. The aim of this study was to document complete rehabilitations in both jaws through the so-called All-on-Four concept (ie, four implants with the posterior implants placed at an angle) using immediate function implants inserted in “nonideal” conditions (eg, implants inserted with dehiscences or fenestrations, in periodontally compromised sites, or in fresh extraction sockets). Materials and Methods: This prospective cohort study included patients with immediately functioning implants placed in difficult conditions to support fixed full-arch maxillary and mandibular prostheses. Results: One hundred forty-two patients received 227 implants. A total of seven implants failed in six patients (three implants in three patients in the maxilla and four implants in three patients in the mandible), for cumulative patient and implant survival rates of 96.2% and 97.7% for the maxilla and 94.7% and 94.8% for the mandible, respectively, after 2 years (Kaplan-Meier). The average (standard deviation) peri-implant bone resorption after 1 year and 3 years in the maxilla was 1.3 mm (0.4 mm) and 1.6 mm (0.4 mm), respectively; in the mandible, the average (standard deviation) peri-implant bone resorption at 1 year and 5 years was 1.4 mm (0.3 mm) and 1.7 mm (0.6 mm), respectively. Conclusions: The results support the conclusion that the four-implant (“All-on-Four”) immediate-function concept in completely edentulous maxillae and mandibles using implants inserted in difficult conditions is a viable concept in the short term.

Purpose: Implant-supported rehabilitation of the atrophic posterior maxilla often necessitates maxillary sinus surgery to augment existing bone volumes. Recent systematic reviews have reported implant survival rates above 90% following sinus elevation. However, statistical assessment of the effect of anatomic factors, implant design and surface, individual risk factors, and complications related to sinus floor elevation procedures on implant survival through analyzing patient data has not yet been performed. The aim of this study is to identify risk factors that might affect implant survival following sinus elevation. Materials and Methods: Three centers were involved in this retrospective multicenter study; 106 patients were treated with 144 sinus elevation procedures and received 328 implants. The mean follow-up was 48.4 months, and the longest follow-up period was 72 months. The analysis considered patient age, gender, health status, and smoking habit; implant size, shape, and surface; residual ridge height; timing of implant placement with respect to grafting; graft material; and the occurrence of surgical complications. For quantitative variables, the Pearson correlation was used. The chi-square test and Fisher exact test (for samples smaller than five units) were used for qualitative variables. Results: The cumulative implant survival rate was 93.0% up to 5 years. Complications occurred in 41 patients. Intraoperative sinus membrane perforation occurred in 40 sinuses (28%) and was not a significant risk factor for implant survival. Six patients experienced postoperative infection leading to graft failure, and two patients had considerable intraoperative bleeding. Smoking more than 15 cigarettes/day and a residual ridge height < 4 mm were significantly associated with reduced implant survival. Conclusions: Smoking habits and residual ridge height should be evaluated carefully prior to sinus elevation procedures. HubMed – rehab

To investigate the correlation between hypoglycemia and positive rate of inborn error of metabolism (IEM) in neonatal intensive care unit.160 patients from a neonatal intensive care unit were enrolled. Blood glucose was measured by Roche Modular chemistry. The dry blood on filter papers, collected from 160 patients, was tested by tandem mass spectrometry to detect 35 inborn errors of metabolism. Clinical follow-up of all the patients was at least in an interval of 12 months. The mean observation period was 13.5 months per child.Based on the ROC curve, the optimal cut-off value of hypoglycemia as an indicator for screening for IEMs was projected to be 2.8 mmol/L, which yielded a sensitivity of 71.4% and a specificity of 76.5%. The patients were divided into two groups: hypoglycemia group (48 cases) and the control group (112 cases). 5(10.4%) of the 48 patients in the hypoglycemia group were positive, while only 2(1.8%) of the 112 patients in the control group were positive. The difference of the positive rate in the screening for IEMs between the two groups was significant (?(2)=4.10, P<0.05); the relative risk (RR) was 5.83 (95% CI: 1.06-32.12).The risk of patients with hypoglycemia suffering from IEMs was significantly higher than that of the non-hypoglycemia patients in NICU, based on cut-off value of 2.8mmol/L.
