10 I I special _ Digital Smile Design a new procedure for capturing the frontal pho- tographs. In addition to general examination, choosing the initial photograph is essential, be- cause the DSD process starts from this point. _Steady head position First of all, it is necessary to observe how the patient speaks, smiles and interacts with his or her head. It is important to note the line joining both eyes. I often see that both eyes are not on the horizontal line. These parameters should be taken into considera- tionforfuturemeasurements.One needs to check the parameters again in the case of treatment for cranio-mandibular dysfunction. I use the slit-lamp stand (used by ophthalmologists) to hold the patient’s head in the optimal 3-D position because it keeps the pa- tient’sforeheadandchinperfectly still. I have learnt that this proce- dureismoreconvenientfortaking the patient’s measurements dur- ing the workflow (Figs. 1a & b). I use frontal photographs for the mock-up for the treatment planpresentation,afterprepara- tion, for measurements for the dentaltechnician,thedigitalbite impression, as well as the veri- fication from mock-ups and all tests, including the final result. In the following, I will present my practical work with the DSD concept in different cases without discussing the smile design process in detail. I can confirm that the digital workflow is very helpful in all steps and cases of aesthetic treatment, because it saves time and yields bet- ter results in horizontal/vertical plans without extensive corrections. _Case 2 Fig. 8_Facial frontal photograph in the headrest, retracted with 8 mm bite increase, DSD.
