It was loaded properly into a rigid impres- sion tray to avoid air entrapment (Fig 5) using a MixStar automatic mixing unit (Fig 6). With the cheek retracted, the loaded impression tray was carefully manoeuvred into position and seated without causing any form of discomfort to the patient. The tray was carefully removed after complete setting of the impression material (3:15 minutes). The fine details were all recorded and the im- plant fixture position was also captured (Fig 7). It was then sent to the labora- tory for fabrication of the final pros- thesis. With an accurate impression, the dental technician was able to fabricate the abutment and the implant crown precisely, consequently expensive and gratuitous remakes can be avoided. At the fitting stage, the customised zirconia abutment was torqued to 35Ncm (Fig 8). Finally, the zirconia implant crown was cemented and the occlusion verified and checked. One week review showed a sta- ble and excellent result (Fig 9 and 10). _Conclusion This method of capturing final im- pressions using a dual viscosity impres- sion technique for implant fixtures has allowed the author to complete all my implant restorations effectively and with great efficiency. The high final hardness of Honigum-Heavy allows exact position- ing of the implant abutment, whilst fine details are precisely captured by the low viscous Honigum-Light. The choice of vis- cosity of impression materials used in this article makes challenging clinical situa- tions easier to tackle and helps to make the restorative procedure enjoyable and impression taking predictable. The complete Honigum impres- sion material range is distributed in the UK and Ireland by DMG Dental Prod- ucts (UK) Ltd.
