1 00:00:00,000 --> 00:00:11,666 2 00:00:11,666 --> 00:00:17,766 This Quick Guide tutorial from exocad shows the "Chain Mode" tooth placement feature. 3 00:00:17,766 --> 00:00:25,266 With the exocad DentalCAD version 2016, the "Chain Mode" feature is available in the "Tooth Placement" dialog, 4 00:00:25,266 --> 00:00:29,766 which appears in the Wizard right after the "Crown Bottoms" dialog. 5 00:00:29,766 --> 00:00:37,099 The general tooth placement functions you should already be familiar with are still available in the "Simple" tab. 6 00:00:37,100 --> 00:00:40,300 These will be explained in a separate tutorial. 7 00:00:40,300 --> 00:00:41,033 8 00:00:41,033 --> 00:00:45,766 Now let's try the chain mode by clicking the "Chain Mode" tab. 9 00:00:45,766 --> 00:00:51,432 10 00:00:51,433 --> 00:00:55,199 The chain mode is represented by a light-blue chain, 11 00:00:55,200 --> 00:00:57,866 green chain control points, 12 00:00:57,866 --> 00:01:01,999 and dark-blue "UFOs" marking the ends of the tooth bow. 13 00:01:02,000 --> 00:01:02,700 14 00:01:02,700 --> 00:01:05,733 There are three different chain modes: 15 00:01:05,733 --> 00:01:08,899 "Chain" transforms all teeth in a chain, 16 00:01:08,900 --> 00:01:12,433 "Single" allows single tooth transformations, 17 00:01:12,433 --> 00:01:16,699 "Tube" transforms all teeth with a fixed bow. 18 00:01:16,700 --> 00:01:17,100 19 00:01:17,100 --> 00:01:19,500 Let's start with the mode "Chain". 20 00:01:19,500 --> 00:01:21,833 21 00:01:21,833 --> 00:01:25,666 22 00:01:25,666 --> 00:01:32,099 Click any point in the tooth bow and drag your mouse to move the whole tooth bow in a chain. 23 00:01:32,100 --> 00:01:40,466 If you click on one of the UFOs, the other UFO will be fixed in it's position automatically, marked by the red point. 24 00:01:40,466 --> 00:01:47,666 This allows you to place just one side's end of the tooth bow at the distal contact point of an existing adjacent. 25 00:01:47,666 --> 00:01:51,166 Both UFO's will be unlocked once you let them off. 26 00:01:51,166 --> 00:01:57,132 That's why I recommend to pin the control point of the UFO once you have finished the placement. 27 00:01:57,133 --> 00:02:04,033 Now you can click and drag the chain at any point without changing the distal position of the pinned UFO. 28 00:02:04,033 --> 00:02:09,366 If you like to completely pin a tooth on it's place, click on it's green control point. 29 00:02:09,366 --> 00:02:11,199 It becomes red then. 30 00:02:11,200 --> 00:02:11,233 31 00:02:11,233 --> 00:02:14,499 This way you can lock any tooth at it's position. 32 00:02:14,500 --> 00:02:16,300 33 00:02:16,300 --> 00:02:22,500 Maybe you already noticed that the teeth will be scaled if you do a big transformation on the chain. 34 00:02:22,500 --> 00:02:23,266 35 00:02:23,266 --> 00:02:25,566 This behavior can be switched off, 36 00:02:25,566 --> 00:02:32,632 with the result that you can not stretch the complete tooth bow wider than the total width of all teeth together, 37 00:02:32,633 --> 00:02:35,366 as the teeth keep their size now. 38 00:02:35,366 --> 00:02:36,832 39 00:02:36,833 --> 00:02:41,999 By default, the teeth always stay in contact while doing transformations. 40 00:02:42,000 --> 00:02:47,766 If switched off, you can create gaps between the teeth when stretching the chain. 41 00:02:47,766 --> 00:02:49,132 42 00:02:49,133 --> 00:02:54,499 Activating "Keep in contact" again will re-established the contacts. 43 00:02:54,500 --> 00:02:55,400 44 00:02:55,400 --> 00:03:01,066 There's another checkbox in the dialog that allows you to show/hide the chain controls. 45 00:03:01,066 --> 00:03:04,632 46 00:03:04,633 --> 00:03:09,833 The undermost checkbox will limit the tooth rotation to buccal/lingual tilt. 47 00:03:09,833 --> 00:03:11,999 This will be shown later in this tutorial. 48 00:03:12,000 --> 00:03:13,766 49 00:03:13,766 --> 00:03:19,432 In chain mode, you have the same options for the tooth placement as in "Simple" mode. 50 00:03:19,433 --> 00:03:21,266 51 00:03:21,266 --> 00:03:25,266 Use the left-mouse button to move parts of the chain. 52 00:03:25,266 --> 00:03:27,066 53 00:03:27,066 --> 00:03:32,599 If there is no adjacent, you may also lock the last teeth of the chain first. 54 00:03:32,600 --> 00:03:34,366 55 00:03:34,366 --> 00:03:39,099 Use Ctrl and the left-mouse button to rotate parts of the chain. 56 00:03:39,100 --> 00:03:39,133 57 00:03:39,133 --> 00:03:45,199 Note: If a tooth is pinned, it can still be transformed when selecting it directly. 58 00:03:45,200 --> 00:03:51,133 But it's protected from being influenced by the neighboring teeth's movements. 59 00:03:51,133 --> 00:03:53,833 60 00:03:53,833 --> 00:04:01,299 Use Shift and the left-mouse button to scale a single tooth in the chain if both ends of the chain are pinned. 61 00:04:01,300 --> 00:04:02,100 62 00:04:02,100 --> 00:04:02,800 63 00:04:02,800 --> 00:04:09,500 Use Ctrl, Shift and the left-mouse button to scale all unpinned teeth in buccal/lingual direction. 64 00:04:09,500 --> 00:04:09,866 65 00:04:09,866 --> 00:04:11,466 66 00:04:11,466 --> 00:04:18,699 If only one end is pinned, then this tooth is used as reference for the scaling with Shift. 67 00:04:18,700 --> 00:04:21,500 68 00:04:21,500 --> 00:04:26,533 69 00:04:26,533 --> 00:04:27,099 70 00:04:27,100 --> 00:04:32,566 If none is pinned, all the teeth will be scaled together with Shift. 71 00:04:32,566 --> 00:04:33,066 72 00:04:33,066 --> 00:04:37,399 73 00:04:37,400 --> 00:04:42,400 74 00:04:42,400 --> 00:04:51,000 In chain mode, the greater the distance to the tooth you move or rotate, the less it influences the adjacents. 75 00:04:51,000 --> 00:04:56,700 If the chain's ends are pinned scaling only affects one tooth size, 76 00:04:56,700 --> 00:05:01,666 but the adjacent's position may change, as they remain in contact. 77 00:05:01,666 --> 00:05:02,232 78 00:05:02,233 --> 00:05:06,533 Rotation actions can be limited to buccal/lingual direction. 79 00:05:06,533 --> 00:05:09,533 80 00:05:09,533 --> 00:05:16,366 Generally when rotating a tooth, only the buccal/lingual tilt will influence the adjacent rotation movements. 81 00:05:16,366 --> 00:05:18,399 82 00:05:18,400 --> 00:05:24,700 All other rotation directions do not influence the tilt of adjacent teeth directly. 83 00:05:24,700 --> 00:05:30,800 Only their positions are affected, as they remain in contact with the tooth you rotate. 84 00:05:30,800 --> 00:05:32,633 85 00:05:32,633 --> 00:05:35,233 Let us now switch to the "Single" mode. 86 00:05:35,233 --> 00:05:42,666 In the "Single" mode, moving or rotating a tooth does not directly influence the placement of the adjacent teeth. 87 00:05:42,666 --> 00:05:49,932 Moving or rotating a tooth may only change the position of the adjacents, as they all remain in contact in the chain. 88 00:05:49,933 --> 00:05:51,999 89 00:05:52,000 --> 00:05:56,966 As you can see now, rotating tooth 11 does not rotate the adjacents. 90 00:05:56,966 --> 00:06:00,699 Scaling has the same effect as in "Chain" mode. 91 00:06:00,700 --> 00:06:01,333 92 00:06:01,333 --> 00:06:06,299 The "Single" mode is perfect to do fine-tweaking on single teeth. 93 00:06:06,300 --> 00:06:07,200 94 00:06:07,200 --> 00:06:10,833 Let's have a look again to the "Chain" mode to compare both modes. 95 00:06:10,833 --> 00:06:11,499 96 00:06:11,500 --> 00:06:21,000 Moving a single tooth in the "Chain" mode will move a series of teeth. The greater the distance, the less is the movement action's influence. 97 00:06:21,000 --> 00:06:32,000 Rotating a single tooth will also rotate a series of teeth in buccal/lingual direction. The bigger the distance, the less is the rotation action's influence. 98 00:06:32,000 --> 00:06:38,566 When you scale a tooth and the ends are pinned, the center of this tooth is used for scaling. 99 00:06:38,566 --> 00:06:38,599 100 00:06:38,600 --> 00:06:43,166 As I already mentioned, I recommend to place the last teeth first 101 00:06:43,166 --> 00:06:45,066 and lock their positions. 102 00:06:45,066 --> 00:06:45,532 103 00:06:45,533 --> 00:06:48,966 Then, continue in chain mode with the canines. 104 00:06:48,966 --> 00:06:49,966 105 00:06:49,966 --> 00:06:54,032 Each time you're happy with a tooth position, pin it! 106 00:06:54,033 --> 00:06:55,033 107 00:06:55,033 --> 00:06:59,899 Next, finalize the anteriors' positions in the "Chain" mode, 108 00:06:59,900 --> 00:07:03,600 109 00:07:03,600 --> 00:07:08,233 or switch to "Single" mode to do some fine-tweaking 110 00:07:08,233 --> 00:07:11,999 111 00:07:12,000 --> 00:07:16,000 and to finalize the arch setup. 112 00:07:16,000 --> 00:07:24,266 The chain mode is a great tool to do a full arch tooth placement. A few clicks are enough to do such a setup. 113 00:07:24,266 --> 00:07:29,332 114 00:07:29,333 --> 00:07:32,766 Let's now also have a look at the "Tube" mode. 115 00:07:32,766 --> 00:07:32,799 116 00:07:32,800 --> 00:07:37,766 When working in "Tube" mode, I recommend to release all tooth positions. 117 00:07:37,766 --> 00:07:38,566 118 00:07:38,566 --> 00:07:45,466 Note: With Ctrl, Shift and the left-mouse button, you can pin or release all teeth. 119 00:07:45,466 --> 00:07:50,699 With Shift and the left-mouse button, you can do the same with a defined series of teeth. 120 00:07:50,700 --> 00:07:51,233 121 00:07:51,233 --> 00:07:55,899 Now you can move all the teeth on a fixed bow, called the tube. 122 00:07:55,900 --> 00:07:56,800 123 00:07:56,800 --> 00:08:04,000 This is a really nice feature to correct the center line when all teeth have already been placed. 124 00:08:04,000 --> 00:08:06,633 125 00:08:06,633 --> 00:08:11,099 We now have seen all modes in the "Chain Mode" tab. 126 00:08:11,100 --> 00:08:15,133 Let us now have a look at another very interesting option, 127 00:08:15,133 --> 00:08:17,466 namely the "Symmetry" option. 128 00:08:17,466 --> 00:08:21,032 The "Symmetry" button actually consists of four buttons. 129 00:08:21,033 --> 00:08:28,399 The upper left button creates an overall symmetry from the patient's right side to the left side. 130 00:08:28,400 --> 00:08:33,766 The upper right button creates an overall symmetry from left to right. 131 00:08:33,766 --> 00:08:33,999 132 00:08:34,000 --> 00:08:39,500 The lower right button creates a front teeth symmetry from left to right. 133 00:08:39,500 --> 00:08:39,833 134 00:08:39,833 --> 00:08:45,299 The lower left button creates a front teeth symmetry from right to left. 135 00:08:45,300 --> 00:08:45,500 136 00:08:45,500 --> 00:08:51,066 Control points appear blue for teeth which will be considered in the symmetry mode. 137 00:08:51,066 --> 00:08:51,132 138 00:08:51,133 --> 00:08:59,933 When moving teeth in front symmetry, the position of the posteriors can be influenced, too, if they are not locked in position. 139 00:08:59,933 --> 00:09:00,166 140 00:09:00,166 --> 00:09:05,966 In "Single" mode, each tooth transformation will be mirrored along the symmetry plane. 141 00:09:05,966 --> 00:09:06,766 142 00:09:06,766 --> 00:09:08,099 143 00:09:08,100 --> 00:09:14,533 Important note: As long as the control point for the symmetry plane is green (not locked), 144 00:09:14,533 --> 00:09:14,566 145 00:09:14,566 --> 00:09:19,066 the plane may change it's position within the tooth bow. 146 00:09:19,066 --> 00:09:27,866 147 00:09:27,866 --> 00:09:36,332 Green arrows on the control point indicate the reference teeth which are used to place/orient the symmetry plane. 148 00:09:36,333 --> 00:09:43,633 You can choose any pair of reference teeth as shown here in front symmetry and even in overall symmetry 149 00:09:43,633 --> 00:09:50,666 simply by pinning them, i.e. the last pinned pair is used as reference. 150 00:09:50,666 --> 00:09:50,766 151 00:09:50,766 --> 00:09:51,832 152 00:09:51,833 --> 00:09:56,933 If you lock the control point, the symmetry plane will stay in place. 153 00:09:56,933 --> 00:10:03,199 The control point's reference points are automatically pinned if you lock the front symmetry plane, 154 00:10:03,200 --> 00:10:09,566 and you can't unlock them as long as the symmetry plane remains locked. 155 00:10:09,566 --> 00:10:16,066 In a front symmetry, transformations for the posteriors will not be mirrored to the other side. 156 00:10:16,066 --> 00:10:18,499 157 00:10:18,500 --> 00:10:26,300 With a plane in "Single" mode, you now have a perfect configuration to do some fine-tweaking on the anteriors, 158 00:10:26,300 --> 00:10:31,666 which will make it very easy to design symmetrical anterior setups. 159 00:10:31,666 --> 00:10:32,466 160 00:10:32,466 --> 00:10:34,199 161 00:10:34,200 --> 00:10:40,466 162 00:10:40,466 --> 00:10:46,832 Note that in symmetry mode, even changes on control points will be mirrored. 163 00:10:46,833 --> 00:10:54,633 164 00:10:54,633 --> 00:10:59,933 A simple click on the "Symmetry" button deactivates the feature again. 165 00:10:59,933 --> 00:11:05,533 166 00:11:05,533 --> 00:11:08,466 Finalize the design in "Single" mode. 167 00:11:08,466 --> 00:11:26,599 168 00:11:26,600 --> 00:11:29,700 Let's try the overall symmetry. 169 00:11:29,700 --> 00:11:34,533 As you can see now, the patient's left side has been mirrored to the right side. 170 00:11:34,533 --> 00:11:35,866 171 00:11:35,866 --> 00:11:38,399 We lock the symmetry plane. 172 00:11:38,400 --> 00:11:39,600 173 00:11:39,600 --> 00:11:48,800 In "Single" mode, as well as in "Chain" mode, all transformations and control point changes will be mirrored to the other side. 174 00:11:48,800 --> 00:11:49,633 175 00:11:49,633 --> 00:11:54,099 If we unlock the symmetry plane and no other point is locked, 176 00:11:54,100 --> 00:11:57,133 the whole tooth bow will be moved. 177 00:11:57,133 --> 00:12:00,999 178 00:12:01,000 --> 00:12:06,500 Let's play around a little with the "Chain" mode and the overall symmetry. 179 00:12:06,500 --> 00:12:15,000 180 00:12:15,000 --> 00:12:19,400 181 00:12:19,400 --> 00:12:27,900 The last option I want to show you is the "Reset" button. This button allows you to reset your placement in different ways. 182 00:12:27,900 --> 00:12:28,700 183 00:12:28,700 --> 00:12:32,600 This option resets all teeth between unpinned teeth. 184 00:12:32,600 --> 00:12:33,400 185 00:12:33,400 --> 00:12:38,633 This option resets everything, but keeps the changes made in the "Simple" tab. 186 00:12:38,633 --> 00:12:39,166 187 00:12:39,166 --> 00:12:43,332 This option resets everything to the initial tooth placement. 188 00:12:43,333 --> 00:12:44,999 189 00:12:45,000 --> 00:12:51,300 The last option will close the "Reset" window and all tooth positions remain as they are. 190 00:12:51,300 --> 00:12:51,400 191 00:12:51,400 --> 00:12:56,500 Let's choose "Reset (keep red)" as it might be the most important reset. 192 00:12:56,500 --> 00:12:58,100 193 00:12:58,100 --> 00:13:01,033 Thank you for watching this video.
