Critical assessment of the scientific evidence is required for the evidence-based practice of a particular treatment modality, which can be reviewed from the well-designed randomized clinical trials, cohort studies, observational studies, retrospective data reviews, etc. In order to fulfil the requirement for best patient care, the evidence-based clinical practice is utmost important. It is recommended to follow particular diagnostic strategies and treatments plans with each plan to be individualized so as to reflect the specific characteristics of individual clinical circumstances. Consensus guidelines have increasingly become an integral part of evidence-based medicine not only in individual and institutional clinical practices but also in serving as a framework with the aim of better patient outcomes and reduce variations, prevent errors, and increase clinicians' accountability in the healthcare practices and help researchers to identify gaps in the evidence and what key research questions have yet to be answered and further discussion and modifications when required by the plenary. The working group also prepared recommendations for future research. Disclosure All the group members were asked to reveal any conflicts of interest that could potentially influence the outcomes of the consensus deliberations based on limited scientific evidence and strict inclusion criteria. No such conflicts were identified. Six topics were discussed, which were as follows: Topic 1: Radiographic techniques in implant dentistry Topic 2: Contemporary surgical guidelines Topic 3: Restorative materials and techniques Topic 4: Implant loading protocols Topic 5: Optimizing esthetic outcomes in implant dentistry Topic 6: Digital-guided solutions Topic 1: Radiographic Guidelines for the Use of Diagnostic Imaging in Implant Dentistry for Anterior Single Implants Diagnostic imaging is an essential component of implant treatment planning. The introduction and widespread use of cross-sectional imaging in implant dentistry using cone-beam computed tomography (CBCT) over the last decade has enabled clinicians to

But one of the major problems faced using this material is that, it is highly prone to plaque accumulation due to surface porosities and its food retentive properties. This in turn increases the bacterial activity causing denture stomatitis. In efforts to impart antimicrobial property to these resins, various nanoparticles (NP) have been incorporated viz. Silver, Zirconia oxide, Titanium dioxide (TiO 2), Silica dioxide (SiO 2) etc. However, as additives they can affect the mechanical properties of the final product. Therefore, the aim of the present study was to evaluate and compare the effect of different concentration of TiO 2 NP on the flexural strength of PMMA resins. Specimens made from heat polymerizing resin (DPI) without NP were used as a control group (Group A). The two experimental groups, (Group B and Group C) had 0.5 and 1 % concentration of TiO 2 NP respectively. The specimens were stored in 37°C distilled water for 50 ± 2 h. A three-point bending test for flexural strength measurement was conducted following ADA specification no. 12. The maximum mean flexural strength (90.65 MPa) belonged to the control group; and acrylic resin with 1 % TiO 2 NP demonstrated the minimum mean flexural strength (76.38 MPa). But, the values of all the three groups exceeded the ADA Specification level of 65 MPa. Conclusion may be drawn from the present study that addition of TiO 2 NP into acrylic resin can adversely affect the flexural strength of the final product and is directly proportional to the concentration of NP.
