Dental Tribune Middle East & Africa Edition | 6/2019 ◊Page C2 IMPLANT TRIBUNE C3 as shock absorbers, reducing load forces on implants.7 The success rate of implant-support- ed hybrid prosthetic treatments is high, as demonstrated by a system- atic review published in 2014, which included 18 studies for evaluation. In a period of five to ten years, high sur- vival rates of 93.3–100 per cent for the prostheses and of 87.9–100 per cent for the implants were found.8 In a retrospective study evaluating the main complications after reha- bilitation with an implant-support- ed hybrid prosthesis, it was observed that the main complication was mu- cositis, which affected 24 per cent of the cases, followed by problems with the prosthetic screws in 13.7 per cent of the cases, including thread wear or loss, and the same percentage was found for fracture of the prosthetic teeth or prosthesis detachment. These problems were related to an incorrect record of vertical dimen- sion, inadequate occlusion or a lack of passive fit of the metallic struc- ture. Another problem encountered concerned the access to the entrance holes of the prosthetic screws (7.8 per cent).9 Conclusion A lower jaw hybrid restoration is a good option for the rehabilitation of an edentulous mandible, and it should be included in the treatment options when evaluating a patient, as it improves aesthetics, function- ality and proprioception. It is fur- thermore easy to clean, requires less prosthetic maintenance, and can be removed at any time and repaired at a very low cost.

Introducing Astra Tech Implant EV The Astra Tech Implant System just got even better—with the new Astra Tech Implant EV. As one of the most well-documented implant systems in the market today—documented in over 1,000 publications in peer- reviewed journals—it continues to evolve and provide great clinical benefits. In fact, the revised implant design change comes with significant ad- vantages—with a deeper implant thread design apically, it is easier to reach preferred primary stability and the handling experience is en- hanced for easy installation. Dr. Mark Ludlow, Division Direc- tor of Implant Prosthodontics and Associate Professor at the College of Dental Medicine at the Medical University of South Carolina, agrees: “You still have all the wonderful properties of TX and EV, but with this new implant, you get better han- dling that helps hit that primary sta- bility—it literally just sinks into the osteotomy.” With this new change in design prop- erties also comes the new name— Astra Tech Implant EV. The new im- plant line will be available starting in the North American market in Octo- ber 2019 and in the European market in early 2020.

Latest clinical data on Astra Tech Implant System The Astra Tech Implant System Os- seoSpeed implants show excellent long-term clinical results, as de- scribed in the article by Windael et. al.** Patients in this study received a total of 105 immediately loaded im- plants in the edentulous mandible. Minimal bone loss, 100% implant survival and 100% prosthetic surviv- al rates were reported at the 10-year follow-up. Using short implant is a solution for patients with limited bone that are unwilling or unable to undergo bone grafting. In a recently pub- ÿPage C4
