DigitalSmileDesign(DSD) As dentists, you may often find you have cases that require complicated treatments and aesthetic proce- dures. A diagnosis from the dental chair is often no longer enough to make a proper analysis and correct diagnosis. Today,itisnecessaryfortheseproce- dures to begin with the use of digital technology with digital pictures and impressions. You can then trans- fer everything to the computer and work on the overall treatment pro- cedure from there rather than di- rectly from the patient. DSD allows you to be more accurate, precise and creative when designing the optimal treatmentprocedure. To create an accurate DSD, you will require: •Adigitalcamera • Digital records (A strict photogra- phy protocol should be followed in every case to keep a concise record and show all aspects of each treat- ment) • A computer programme suitable forAestheticDentistry • Study models for taking real meas- urementsoftheteeth. Thefollowingstepscanthenbeused tocompleteyourDSDrestorations: 1. It is first-off important that you have a good knowledge of Aesthetic Dentistry basics in order to create a DSD. Youshouldbeabletorecognise the correct position and proportion of all elements involved in a beauti- fulsmile,including: • Teeth exposure during rest posi- tion and smile according to the age ofthepatient •Midline-facialanddental • Smile line - high smile, medium smile or low smile, ie: how much of and how many teeth show when smiling •Profile-convexorconcave • Gum exposure – identifying a gummy smile and the correct proce- dureforsolvingthisproblem •Smilesymmetries • Teeth size, color, texture and pro- portion • Papillas – the correct amount of in- terdental papila exposure will deter- minethebeautyofeachsmile 2. Once you have transferred all of the records to your computer, you can then analyse the patient’s pic- tures and work in all of the above parameters, both extraoral and in- traoral(SeeFig.1a,Fig.1b) 3. Using the suitable programme, you can then design the appropriate smile for the individual patient. (See Fig.2a,Fig.2b,Fig2c) 4. Once the DSD has been created, you can transfer all of the informa- tion to the lab technician allowing him/her to build the wax-up and finally proceed to the mock-up (a prototypeofrestorationsthatwillbe created).

After the mock-up has been test- ed and adjusted as necessary, you should then check that the DSD matches what has been created. You are then able to carry on the restora- tionsasplanned. You will find a DSD is a remarkable tool for planning a treatment proce- dure digitally as well as creating the wax-up and future mock-up, tem- poraries and final restorations. It is the best way to work closely with the laboratory (see Fig. 3), saving time and further patient visits and you are able to show the patient actual approximate results with the com- puterimageyouhavecreated. ÿPage 32 Fig. 4c:Rest position to evaluate the teeth exposureand thelipsupport Fig. 5e: Final situation with preliminary designoverlaping tocheckaccuracy KCL DI PRESS AD JAN 2017 v2.indd 117/01/201710:22
