1 00:00:00,000 --> 00:00:11,533 2 00:00:11,533 --> 00:00:17,066 This Quick Guide tutorial from exocad shows how to use the "Thimble Crown" cutback library 3 00:00:17,066 --> 00:00:20,432 to design an implant bridge type wrap around. 4 00:00:20,433 --> 00:00:21,233 5 00:00:21,233 --> 00:00:28,133 You may try this with the demo sample called "Screw retained implant Bridge with virtual gingiva design". 6 00:00:28,133 --> 00:00:29,399 7 00:00:29,400 --> 00:00:36,566 Starting with exocad version 2016, there are a new options for waxup restoration types called "design waxup digitally". 8 00:00:36,566 --> 00:00:38,399 9 00:00:38,400 --> 00:00:43,866 Furthermore, for all restoration types there is now a virtual gingiva design mode. 10 00:00:43,866 --> 00:00:45,599 11 00:00:45,600 --> 00:00:49,100 The same modes are also available for pontics. 12 00:00:49,100 --> 00:00:50,900 13 00:00:50,900 --> 00:00:57,700 You will find more detailed information about virtual waxup and gingiva design in a separate video tutorial. 14 00:00:57,700 --> 00:00:59,333 15 00:00:59,333 --> 00:01:01,233 Let's proceed to the design. 16 00:01:01,233 --> 00:01:07,199 17 00:01:07,200 --> 00:01:12,666 If not required, you can skip the emergence profile step and proceed to the next step 18 00:01:12,666 --> 00:01:15,199 which will be the tooth placement. 19 00:01:15,200 --> 00:01:21,766 Make sure that you use the correct tooth library. Only exocad's "generic" library includes the thimble crown shapes. 20 00:01:21,766 --> 00:01:25,832 Why not use the "Chain Mode" to do the tooth placement. 21 00:01:25,833 --> 00:01:27,566 22 00:01:27,566 --> 00:01:32,832 You will find more information about the chain mode in a separate video tutorial. 23 00:01:32,833 --> 00:01:37,666 24 00:01:37,666 --> 00:01:41,132 It is a very nice tool to design full arch setups. 25 00:01:41,133 --> 00:01:48,333 26 00:01:48,333 --> 00:01:50,833 Proceed to the next step. 27 00:01:50,833 --> 00:01:54,366 28 00:01:54,366 --> 00:01:56,499 Let's skip the free-forming. 29 00:01:56,500 --> 00:01:57,900 30 00:01:57,900 --> 00:02:02,733 Select "Design virtual gingiva" in the "Virtual Waxup Bottom" dialog. 31 00:02:02,733 --> 00:02:07,266 Click "Apply" to start blocking out the virtual gingiva's bottom. 32 00:02:07,266 --> 00:02:08,499 33 00:02:08,500 --> 00:02:13,666 A separate video tutorial will explain the available settings in this dialog. 34 00:02:13,666 --> 00:02:14,966 35 00:02:14,966 --> 00:02:19,999 Proceed to the gingiva design step to draw the margin of the gingiva. 36 00:02:20,000 --> 00:02:26,166 37 00:02:26,166 --> 00:02:30,766 Add as many points as required to define the gingiva area. 38 00:02:30,766 --> 00:02:52,766 39 00:02:52,766 --> 00:02:55,699 Finish the drawing with a double-click. 40 00:02:55,700 --> 00:03:08,733 41 00:03:08,733 --> 00:03:11,966 Then proceed to the gingiva design step. 42 00:03:11,966 --> 00:03:16,266 43 00:03:16,266 --> 00:03:20,966 Free-forming the gingiva will be explained in detail in a separate video tutorial. 44 00:03:20,966 --> 00:03:22,032 45 00:03:22,033 --> 00:03:26,699 If required, you can do some adjustments on the gingiva design. 46 00:03:26,700 --> 00:03:38,833 47 00:03:38,833 --> 00:03:41,666 Then proceed to the next step. 48 00:03:41,666 --> 00:03:46,599 In this important step, you can now select between different cutback libraries. 49 00:03:46,600 --> 00:03:51,000 Let's choose "thimble" for the particular case in this tutorial. 50 00:03:51,000 --> 00:03:56,800 You will find more general information about all cutback libraries in a separate video tutorial. 51 00:03:56,800 --> 00:04:02,800 52 00:04:02,800 --> 00:04:07,400 Click "Apply" when you have selected the desired library 53 00:04:07,400 --> 00:04:10,066 54 00:04:10,066 --> 00:04:12,466 and proceed to the next step, 55 00:04:12,466 --> 00:04:15,766 which is the free-forming step. 56 00:04:15,766 --> 00:04:18,266 57 00:04:18,266 --> 00:04:22,099 Before you do that, I recommend to switch to the Expert mode 58 00:04:22,100 --> 00:04:29,333 and choose "Tooth Placement" to do some fine-tweaking on the thimble crowns' positions, if necessary. 59 00:04:29,333 --> 00:04:30,833 60 00:04:30,833 --> 00:04:36,666 Here you have exactly the same placement features as in the tooth placement. 61 00:04:36,666 --> 00:04:37,232 62 00:04:37,233 --> 00:04:41,233 You can still move, rotate, and scale the cutback libraries. 63 00:04:41,233 --> 00:04:47,999 64 00:04:48,000 --> 00:04:52,000 Next, stay in Expert mode and choose "Free-form Gingiva". 65 00:04:52,000 --> 00:04:59,066 66 00:04:59,066 --> 00:05:04,066 Try to avoid overlapping the gingiva and thimble crown borders. 67 00:05:04,066 --> 00:05:20,666 68 00:05:20,666 --> 00:05:24,666 When you are done, click "OK" to close this dialog. 69 00:05:24,666 --> 00:05:27,032 70 00:05:27,033 --> 00:05:32,399 Still, stay in Expert mode and proceed to the "Shrink Gingiva Design Part" step. 71 00:05:32,400 --> 00:05:34,833 72 00:05:34,833 --> 00:05:45,466 In the gingiva cutback step, the lingual part of the gingiva and the cross-section areas with the anatomical teeth are excluded from shrinking. 73 00:05:45,466 --> 00:05:46,699 74 00:05:46,700 --> 00:05:51,800 We can use this feature for less shrinking of gingiva borders around teeth. 75 00:05:51,800 --> 00:05:55,433 To achieve this, we will perform a multi-level cutback. 76 00:05:55,433 --> 00:06:00,399 First, we shrink the buccal part excluding the borders with 0.5 mm. 77 00:06:00,400 --> 00:06:01,533 78 00:06:01,533 --> 00:06:06,133 Note that the "Shrink Gingiva Design Part" is only accessible in the Expert mode. 79 00:06:06,133 --> 00:06:12,066 80 00:06:12,066 --> 00:06:15,366 Then we activate "Multi-Level Cutback, 81 00:06:15,366 --> 00:06:17,332 82 00:06:17,333 --> 00:06:19,466 we clear all excluded parts, 83 00:06:19,466 --> 00:06:23,332 and we choose a second shrinking depth of 0.2 mm. 84 00:06:23,333 --> 00:06:27,333 This will now be applied to the whole restoration. 85 00:06:27,333 --> 00:06:31,099 86 00:06:31,100 --> 00:06:38,066 There's also another method for gingiva cutback, which will be covered in a separate video tutorial. 87 00:06:38,066 --> 00:06:41,232 88 00:06:41,233 --> 00:06:45,233 We click on the "OK" button to close this dialog. 89 00:06:45,233 --> 00:06:46,466 90 00:06:46,466 --> 00:06:51,799 Now we can continue in the wizard and restart at the stage where we left it. 91 00:06:51,800 --> 00:06:55,166 92 00:06:55,166 --> 00:06:59,566 Here it is even possible to free-form the thimble crowns. 93 00:06:59,566 --> 00:07:05,032 94 00:07:05,033 --> 00:07:08,033 "Cusps" allows you to modify the upper parts, 95 00:07:08,033 --> 00:07:13,899 96 00:07:13,900 --> 00:07:16,400 "Tooth Parts" moves bigger areas, 97 00:07:16,400 --> 00:07:22,833 98 00:07:22,833 --> 00:07:26,033 "Entire Tooth" moves the whole thimble crown, 99 00:07:26,033 --> 00:07:31,633 100 00:07:31,633 --> 00:07:35,633 and "Ridge" just the top ridges of the thimble crown. 101 00:07:35,633 --> 00:07:49,833 102 00:07:49,833 --> 00:07:53,833 Proceed to the next step. 103 00:07:53,833 --> 00:07:56,466 104 00:07:56,466 --> 00:08:03,066 Starting with exocad version 2016, you can delete all connectors with a click in the "Connectors" dialog. 105 00:08:03,066 --> 00:08:04,899 106 00:08:04,900 --> 00:08:09,100 Click "Next" to merge all meshes into a virtual waxup. 107 00:08:09,100 --> 00:08:10,300 108 00:08:10,300 --> 00:08:13,600 This operation may take a while. 109 00:08:13,600 --> 00:08:25,933 110 00:08:25,933 --> 00:08:30,933 Then click on "Next" to free-form the whole merged restoration. 111 00:08:30,933 --> 00:08:44,833 112 00:08:44,833 --> 00:08:51,966 Here you can use the "Adapt" feature to create a uniform gap between restoration and gingiva. 113 00:08:51,966 --> 00:09:06,399 114 00:09:06,400 --> 00:09:12,733 Furthermore you can add and remove material, smooth parts or move bigger areas. 115 00:09:12,733 --> 00:09:39,566 116 00:09:39,566 --> 00:09:43,232 Click "Next" to proceed to the next step. 117 00:09:43,233 --> 00:09:48,166 118 00:09:48,166 --> 00:09:50,066 Switch off all screw holes, 119 00:09:50,066 --> 00:09:53,099 and click "Next" to finish the design. 120 00:09:53,100 --> 00:10:08,900 121 00:10:08,900 --> 00:10:14,866 We created a nice thimble crown implant bridge in not even 10 minutes. 122 00:10:14,866 --> 00:10:24,866 123 00:10:24,866 --> 00:10:28,866 Thank you for watching this video.
