B4 I N DUST RY N EWS Dental Tribune U.S. Edition | December 2017 Functional and esthetic overdentures By Marco Montanari, DDS The removable denture may seem an outdated rehabilitation. However, it is the foundation on which all prosthetic proce- dures are based; therefore, it is imperative to know it and to follow its constructive steps when restoring the patient’s oral cav- ity to obtain an esthetic result not only of the smile but of the whole face. The possibility to anchor a denture to teeth/roots or implants enables the ben- eits of a removable prosthesis in terms of soft-tissues support, oral hygiene and the greater stability associated with the use of retentive attachments. Preserving roots for the anchoring of a denture provides several strategic ad- vantages, including the maintaining of the alveolar bone (for preserving the peri- odontal ligament), proprioception and physiological masticatory dynamics (Scot- ti R. et al., 2003). After an endodontic treatment, different types of post attachments can be applied into the roots. These attachments can be identiied as spherical attachments and low proile attachments. Spherical attachments (Pivot Block Normo and Micro and Pivot Flex, Rhein83, Italy, www.rhein83.com) are good anchor- ing devices because of their self-aligning capacity, small dimensions (in particular for the Micro sphere) and ability to com- pensate severe divergences between the roots (Flex). Today’s spherical attachments have further evolved into the low-proile Today’s spherucal attachments have evolved unto the low-proile Puvot OT Equator (Rheun83). Thus new attachment mauntauns the same duameter and retentuve capacuty as the Puvot Block Normo sphere but has a substantually smaller vertucal suze (only 2.2 mm, uncludung the retentuve cap and the housung). Photos/Provdded by Marco Montanard, DDS, and Rhedn83 AD Pivot OT Equator (Rhein83). This new at- tachment maintains the same diameter and retentive capacity as the Pivot Block Normo sphere but has a substantially smaller vertical size (only 2.2 mm, includ- ing the retentive cap and the housing). These attachments are recommended when there is the need of a good anchor- age for denture but the available pros- thetic space is reduced. The Pivot OT Equa- tor, thanks to its sandblasted pin, ensures greater retention inside the root canal, and the nitride surface improves the resistance of the attachment and reduces the wearing process over time. The morphology of the OT Equator at- tachment has been validated for more than 10 years by clinical procedures and scientiic studies performed on implant- denture rehabilitations (Montanari et al., 2015-2016). For all these reasons, I believe that the Pivot OT Equator is the most effective and reliable overdenture retentive post cur- rently on the market.

One week later the CleanImplant Foundation presented the third award in Tokyo at the 13th Annual MegaGen International Symposium to Dr. Kwam Bum Park, active implantologist and CEO of the Korean implant manufac- turer. Implants of many more manufac- turers are already in the process of com- prehensive analyses and will be published soon, according to the foundation. According to Albrektsson, the industry should abide to his fundamental guiding principle written in an article a decade ago to not only believe — but know — that the implants being used do not harm patients. Because patients trust practitioners’ de- cisions regarding dental implant systems, dentists can beneit from access to an in- dependent guide covering which implant systems meet the expectation of a high- quality medical device. The CleanImplant Foundation reports that it will support future research on the clinical impact of impurities and extend the periodic analyses of dental implants across the globe to provide dentists with independent research results. Addition- ally, it will evaluate improvements in the manufacturing process of previously an- alyzed implants. Details and a newsletter are available at www.cleanimplant.com.
