49 4 2016 implants Premier online course reveals Secrets of the All-on-4® treatment concept Plaque-identifying toothpaste to reduce Risk of heart disease and stroke Study compares accuracy of Optical scans and silicone impressions For those looking to learn more about the evidence-based All-on-4® treatment con- cept1–4 , a new free online course offers a way to build knowledge that’s essential for a successful start with this proven protocol. The training, offered by Nobel Biocare, has been developed for any clinician looking to increase their understanding of this established concept. The perfect complement to hands-on and classroom training, the free three-hour online course introduces the concept and covers the key considerations, from diagnostics to planning, implementation and follow-up. The course has been developed with Dr Saj Jivraj, a leading prosthodontist, and Dr Hooman Zarrinkelk, an experienced, board- certified oral and maxillofacial surgeon, who host the videos that make up the course. As colleagues in California, US, the two experts have been successfully treating patients with the All-on-4® treat- ment concept for ten years, and are experienced educators in the required techniques. On completion of the course, participants will earn three CE credits5 and a certificate from Nobel Biocare. Those interested in registering for the training, or who would like more information, should visit nobelbiocare.com/all-on-4course. Source: Nobel Biocare Health experts worldwide agree that oral health and inflammatory diseases, such as cardiovascu- lar disease and stroke, are correlated. A recently published study has shown that users of a tooth- paste that identifies plaque build-up on teeth also exhibited lower levels of a heart disease marker, suggesting that the toothpaste resulted in statis- tically significant reductions in dental plaque and inflammation throughout the body. An analysis showed that the plaque-identifying toothpaste reduced the mean plaque score by 49 per cent compared with a 24 per cent reduc- tion in the placebo group. In addition, lab- oratory tests in a pre-specified sub- group of 38 participants found that the plaque-identifying toothpaste reduced levels of high-sensitivity C-reactive pro- tein (hs-CRP), a sensitive marker for future heart attacks and strokes, by 29 per cent, while hs-CRP levels increased by 25 per cent in individuals using the placebo toothpaste. The researchers concluded that the observed reduction supports the hypothesis that Plaque HD could reduce the risk of cardiovascular disease. However, a large-scale randomized trial of suf- ficient size and duration is needed to verify the results, they stated. The study, titled “Random- ized trial of plaque identifying toothpaste: Dental plaque and inflammation,” was published online on Oct. 19 in the American Journal of Medicine ahead of print. It was conducted at Florida Atlantic University in the US. Aiming to evaluate the accuracy of digital impres- sions for use in implant placement, researchers from Iwate Medical University in Japan have com- pared optical impression scans from an intra-oral scanner with conventional silicone impressions. The analysis showed that the distance error of the optical impressions was slightly greater that of the conventional method. The evaluation was limited to the use of optical impressions for implant placement. For this purpose, the re- searchers placed two implant abutments (Nobel Biocare), one 5 mm and one 7 mm in height, in a master model. As distance errors of the optical impression were slightly greater than that of the conven- tional impression, the researchers concluded that currently digital impressions are not equiv- alent replacements of conventional impres- sions for restorative procedures. However, they predicted that the development of information technology would most likely lead to improve- ment in the accuracy of optical impressions in the near future. The study, titled “Examination of the position accuracy of implant abutments reproduced by intra- oral optical impression”, was published on- line on 5 October in the PLOS ONE journal. news Literature © G ts /S h u tt e rs to c k .c o m © Irina Qiwi/Shutterstock.com 42016
