“…Finally, although all studies used radiographic evaluation by intraoral radiography to assess the peri-implant bone loss, there are other useful radiographic techniques, such as multislice computed tomography and cone-beam volumetric imaging, which offer certain advantages to implant dentistry, such as the representation of intraosseous lesions in three planes, on a real scale and without overlapping or distortion. In addition, computer-assisted image analysis, such as subtraction radiography, allows the detection of small changes in bone density ( Heitz-Mayfield, 2008 ; Naveau et al., 2019 ; Trivedi et al., 2022 ). The different cutoff levels reported for the different clinical parameters and the different methods of statistical analysis in the included studies should also be taken into account; only three of them ( Park et al., 2021 ; Blanco et al., 2022 ; Polymeri et al., 2022 ) resorted to the Shapiro–Wilk test to contrast the normality of the data.…”

Peri-implant diseases are pathological conditions that affect the survival of dental implants. Etiological studies are limited, accepting a prevalence of 20% at the implant level and 24% at the patient level. The benefits of adjuvant metronidazole are controversial. A systematic review and meta-analysis of RCTs according to PRISMA and PICOS was performed with an electronic search over the last 10 years in MEDLINE (PubMed), WOS, Embase, and Cochrane Library. The risk of bias was measured using the Cochrane Risk of Bias tool and the methodological quality using the Jadad scale. Meta-analysis was performed with RevMan version 5.4.1, based on mean difference and standard deviation, with 95% confidence intervals; the random-effects model was selected, and the threshold for statistical significance was defined as p < 0.05. A total of 38 studies were collected and five were selected. Finally, one of the studies was eliminated because of unanalyzable results. All studies reached a high methodological quality. A total of 289 patients were studied with follow-up periods from 2 weeks to 1 year. Statistical significance was only found, with respect to the use of adjunctive metronidazole, in the pooled analysis of the studies (p = 0.02) and in the analysis of the radiographic values reported on peri-implant marginal bone levels, in the studies with a 3-month follow-up (p = 0.03). Discrepancies in the use of systemic metronidazole require long-term randomized clinical trials (RCTs) to determine the role of antibiotics in the treatment of peri-implantitis.

“…Considering hybrid ceramics, doubts about the appropriate combination of ceramics and adhesive cement retained mono-implant were common. Patients tended to accept dental implants for the repair of partly edentulous arches due to cosmetic conformity, functional competence, and a high percentage of survival 1,2 . Fixed prostheses supported by implants could be screwed or retained to implant abutments 3 .…”

Background: The finite element method (FEM) is expected to be one of the most effective computational tools for measuring the stress on implant-supported restorations. This study was designed using the 3D-FEM to evaluate the effect of two adhesive luting types of cement on the occlusal stress and deformation of a hybrid crown cemented to a mono-implant. Materials and Method: The mono-screw STL file was imported into the CAD/CAM system library from a database supported by De-Tech Implant Technology. This was to assist in the accurate reproduction of details and design of a simulated implant abutment. Virtually, a digital crown was designed to be cemented on an abutment screw. A minimum occlusal thickness of 1mm and marginal fitting of 1.2mm was intended. An 80µm cement interface thickness for this study’s purposes was applied using U-Cem Premium and 3M RelyXTm adhesives. The FEA software meshed into tetrahedral elements. Two three-dimensional finite element models were simulated under different loads of 200N, 400N, 600N, 800N, 1000N, 1200N, and 1400N. Results: The results showed that the hybrid ceramic crown attached to a mono-implant with each adhesive cement exhibited comparable stress and strain. However, the amount of distortion was less when RelyX cement was used. Conclusion: Overall, it was advisable to use 3M RelyXTm adhesive cement up to 1400N load.

Aim: The study aimed to compare the clinical and radiographic outcomes of bone volume, density, and crestal bone levels in conventionally placed dental implants with and without local application of 1% metformin (MF) gel using cone-beam computed tomography (CBCT) at 9 months. Materials and Methods: Twenty implants were placed in 18 individuals, randomly divided into 2 groups where Group A received a local application of 1% MF gel along with implant placement. In contrast, Group B received implant placement alone. After thorough clinical examination and preoperative CBCTs, implants were placed under aseptic conditions. Patients were recalled at 3 and 9 months after surgery. Implants were functionally loaded by the end of 3rd month. Soft-tissue parameters such as modified plaque index and modified sulcular bleeding index were recorded along with CBCT evaluation to assess the crestal bone loss, bone density measurement, and bone volume, postoperatively. Fisher’s extract test, independent and paired t-test, and Bonferroni analysis were used to determine statistical significance with P ≤ 0.05. Results: There was no discernible difference between the groups regarding soft-tissue parameters, bone density, and crestal bone levels. However, comparing bone volume between the test and control groups at 9 months was statistically significant. The test group with 1% MF gel showed increased bone volume around the implant. Conclusion: The data obtained were strong enough to suggest that 1% MF gel administered locally can increase peri-implant bone volume, possibly due to its additional property favoring osteoblastic stimulation and proliferation.
