Nowadays it is possible to perform an optimal implant placement and to achieve a good long-term prognosis for an implant-borne prosthesis in the grafted posterior maxilla. This study evaluates the efficiency of one-stage piezosurgery by using as graft material a combination of particulate bovine bone substitutes with platelet-rich fibrin to achieve sinus lift. We included in this study 14 cases of one-stage sinus lift surgeries during which we placed 30 standard implants. The mean vertical bone height gain was 10.12 mm six months after surgery, and the mean postoperative follow-up time was 43.79 months. There were no major complications during or after surgery, and all implants are in use. Therefore, it can be concluded that one-stage sinus piezosurgery using particulate bovine bone substitutes and platelet-rich fibrin can be applied as a predictable and effective technique in the treatment of the posterior edentulous maxilla ensuring 4-5 mm vertical bone height.

C-reactive protein (CRP) is a non-specific inflammatory marker, correlated with the severity and prognosis of ischemic stroke. We performed a retrospective study in which were included 81 patients diagnosed with acute ischemic stroke admitted between January and July 2017 in the Department of Neurology, Sibiu Emergency Clinical Hospital. CRP values were classified on three levels (0 - 5 mg / L, 5 - 50 mg / l and] 50 mg / l). We examined the correlation between CRP levels according to the type of ischemic (lacunar / territorial) stroke, the degree of motor deficit (quantified by the mRC scale), the associated risk factors and the mortality rate. PCR values above 50 mg / L were found in patients with territorial stroke (15%). Moderate motor deficits predominate, with PCR values ranging from 5-50 mg / L. The most important risk factors found in the patients included in our study were hypertension and atherosclerosis. We made correlations between these risk factors and the PCR values. In most cases with these two risk factors were recorded a mean PCR value (5-50 mg / L).For atherosclerosis the results were statistically significant, p = 0.021. Most patients (56%) had CRP levels ranging from 5 to 50 mg / L. These values recorded highest death rates. PCR it is an important marker of inflammation and it is important to be determined in all patients with acute ischemic stroke, especially which is thought to be correlated with the prognosis of these patients.

Objectives To evaluate the effectiveness of 0.2% delmopinol mouth rinse in maintenance of peri‐implant tissue health and prevention or inhibition of peri‐implant mucositis and peri‐implantitis. Materials and Methods Four weeks following tooth extraction, eight titanium dental implants, were placed in six dogs' mandibles. Three dogs were assigned to the test or placebo mouth rinse. Eight weeks following implant installation (T2) ligature was placed to induce peri‐implant disease. Clinical and radiographic assessment was performed during the study period as well as micro‐CT analysis and histologic assessment to evaluate Bone‐Implant Contact at the end of the follow‐up (T4). Results Plaque at implant sites before ligature placement (T2) was lower for the test group (0.7 ± 1.0 vs 1.5 ± 1.3, P < .05). The ratio of affected implant (PD ≧4 mm) at T2 and T4 in the test group was significantly smaller than that of the placebo group (T2, 17% vs 47%, P < .01; T4, 67% vs 83%, P < .05). The test agent also seemed to be effective in partially preventing bone loss induced by ligature placement according to the Computed Tomography and histologic analysis (test, 1.1 ± 0.8 mm; placebo, 1.5 ± 0.9 mm). Conclusions Within the limits of this animal model study, the results of the study indicate that the 0.2% delmopinol rinse might play a role in prevention of peri‐implant disease development.

The present study assessed the retention forces corresponding to different telescopic systems used in removable prosthetic dentures. The telescopic systems were represented by Co–Cr alloy or zirconia-based primary crowns and Co–Cr secondary crowns. All crowns were manufactured using computer-aided design/computer-aided manufacturing technology (CAD/CAM). Two types of reference abutment teeth (upper canine and first upper molar) were selected in order to obtain the telescopic crowns and two taper angles—of 0° and 2°—were used for the design of the crowns. A number of 120 samples of telescopic crowns were obtained and subjected to mechanical tests, following a specific protocol, on a mechanical testing equipment. The retention of the telescopic systems was evaluated for different sets of cycles (up to 360), represented by movements that simulate the intraoral insertion and disinsertion of the telescopic systems. The present study highlights that the telescopic systems in which the primary crown is made of zirconia ceramics presents more advantages than those made of Co–Cr. All telescopic systems studied, highlighted that by modifying the taper angle from 0° to 2°, the retention forces have decreased, irrespective of the materials used for the fabrication of the primary crown, suggesting that by using a taper angle of 0°, which is known to be ideal, more efficient, and reliable prosthesis can be developed. Thus, even though the ceramic–metallic telescopic system exhibited the highest retention, all telescopic crowns evaluated registered values between 2–7 N, indicating that they are suitable for clinical use.
