6.1 Screenshots

Individual tabs are used to design the restoration:
Scan
,
Margin, Design, and Mill
The choices you make on each tab affect the options available on that and related tabs. The typical restoration utilizes the tabs from left to right. Moving backwards in the process (e.g., modifying the settings in the Margin tab after completing the design in the Design tab) can cause settings and designs to be discarded. The system warns you when your actions will cause design data to be discarded.
Some system configurations will restrict the use and access of individual tabs.
You may wish to save an image of the screen for communicating with associates or Planmeca.

13.2 Block selection

The following guidelines will help you with the selection of the correct block. For detailed information, contact your local Ivoclar Vivadent or 3M ESPE representative:
3M Lava Ultimate is a nano resin ceramic, ideal for all indications including implant superstructures. Fast milling, no firing for great results.
Ivoclar Vivadent categorizes their IPS Empress® block selection by amount of translucency; LT blocks have lower translucency and therefore are more opaque, allowing some visual blocking of the underlying tooth structure (ideal for full coverage). HT blocks are higher translucency blocks; they are great for inlays and onlays where surrounding tooth structure can positively affect the aesthetic outcome.
Multi-blocks are blended in colour and translucency from cervical to incisal and allow for complete aesthetic control.
IPS e.max is a lithium disilicate glass-ceramic material that comes in a pre-crystallized state which changes colour and strength when fired. In its final tooth coloured state, IPS e.max CAD offers 360 MPa of flexural strength which is nearly three times the strength of many millable ceramics available chair side. Adjustments should be made to the e.max restorations while in the blue stage.
IPS e.max Impulse are supplied in three Values (Value 1, 2, 3) and two Opal shades (Opal 1, 2). They are mainly used for veneers. The Value blocks feature different brightness values: 1 is the lowest and 3 the highest. The Opal blocks exhibit a decreasing opalescence and increasing brightness value from 1 to 2.
Telio CAD blocks are intended for long-term provisional restorations (maximum wear of 12 months).
Burn Out Blocks (BOB) are used to manufacture an acrylic pattern for further fabrication methods utilizing the burnout technique, including casting and pressing for inlays, onlays, crowns, as well as other dental applications.
The block selection chart provides general direction on what block or category of block is recommended for different types of restorations. Please understand that the clinical situations and parameters (preparation, occlusion, patient compliance) are all factors in the success of the final restoration regardless of the material.

15.2 Scanning overview

To capture the image of a tooth/teeth (pre-operative or wax-up), preparation, opposing teeth, buccal bite, and/or bite registration scan the restoration site with the scanner.
Scanning the restoration site requires proper site preparation, correct placement and movement of the scanner, and a sufficient number of scans to ensure adequate digitalization of the restoration site. The basic work-flow is described below.
1. Select the desired scanning mode:
Pre-op - For using the patient’s existing dentition or a wax-up as the pre-op model for creating the restoration.
Prep - For scanning the prepared site of the restoration. All free flowing blood, saliva, and residue should be removed from the preparation site before scanning.
Opposing - For scanning the teeth on the opposite arch of the preposition.
To ensure good alignment scan the same number of teeth as there is in the preparation model.
Buccal - For scanning the buccal view of the preparation, adjacent and opposing teeth.
Bite - For defining the occlusal anatomy of a bite registration. This button is active when Bite Registration is selected.
2. Shield the site from strong extraneous light sources (dental lights, sunlight, etc.).
3. Activate the laser by clicking the button on the scanner.
The live image will be displayed on the screen.
4. Place the scanner so that the camera is centred over the occlusal of the restoration site.
The system assumes that the first scan is taken from the occlusal. Ensure the first scan is taken at a 90 degree angle to the occlusal surface. If the first scan is not optimal, delete it and retake it.

15 SCANNING
15.3.1 Occlusal scan
The first scan is of preparation
1. Keep the scanner parallel to the occlusal table.
2. Take overlapping scans and move in half-tooth (or less) increments.
The last occlusal scan is the centre of the mesial proximal neighbour.
15.3.2 Clockwise rotation scan
15.3.3 Distal adjacent tooth scan
The right side of the scanner is stronger because of how the laser is reflected. That is why you always want to rotate to the right before going to the left.
1. Use small rotations over the mesial proximal neighbour to create overlapping scans as you transition from occlusal scans to a clockwise rotation.
2. Scan along the right side of the teeth. Rotate the scanner to almost 90° from the occlusal table.
3. Watch as your model builds to see any areas that might require a different rotation or angle.
Rotate in small increments across the distal adjacent tooth until you reach the left-hand side. This enables you to capture the occlusal data as you shift from one rotation to the other.

15.6 Using eraser tool

The Eraser Tool can be used to remove unnecessary data like extra teeth, tongue, cheek, etc. It can also be used to erase an area that needs to be rescanned. If you spot a problem (i.e. the margin is partially hidden by cord or tissue), you can erase that area, correct the problem on your model or intraorally, then rescan just that area. You do not have to start over.
Be sure to erase and rescan ALL modified areas.
The Eraser can also be used in the Pre-op and Bite Registration Time Saver tools (see the following sections).
Click the Eraser tool to deactivate it and regenerate the model.
Keep some of the buccal or lingual data when erasing. If you disconnect the two halves of the model, half of the model will disappear. It is also recommended that you not delete multiple teeth in a row. Large gaps in the model is not recommended.

Prep model can be copied into Bite Registration
The instructions below assume that you will use the Time Saver method. You always have the option of simply doing a full scan for each model type.
A bite registration can be used to optimize occlusion for proper alignment with the opposing tooth. Scan the preparation, ensuring there is enough detail of the adjacent dentition and/or gingival tissue in your preparation scans to align the bite registration scans.
After scanning the preparation, prepare the bite registration.
Keep the following recommendations in mind as you prepare bite registrations:
1. Place the bite registration material so that it completely covers the preparation surface:
The bite registration material should not cover the adjacent teeth. If it does, trim to the interproximal after the material sets.
There must be sufficient data of the adjacent teeth in the scans of the preparation and the bite registration in order for the two models to align.
Ensure there are no gaps between the bite registration material and the adjacent teeth.
2. Ask the patient bite down firmly or press the articulated model down firmly for the impression.

15.15 Scanning an anterior

The scanning pattern for anteriors is similar to the posteriors. Since there is more varying data on the lingual side, it is recommended to scan the linguals before the occlusals.
Anterior teeth are often very similar to each other. To lowers the chances of misalignment follow the suggested scanning steps. The scanning method is the same for all anteriors.
When scanning intraorally, it may be more comfortable to have the scanner tip pointing towards the mesial instead of the distal. In this case, the surface indicators on the model will be incorrect until the orientation is changed.
1. Start on the Prep and scan the occlusal of the prep and the mesial proximal.
2. Rotate to the lingual and scan the prep and proximals.
3. Rotate across the distal proximal to reach the facial side.
4. Scan the facial side.
Watch the model as it processes to ensure the scans are applied to the correct area. Anterior teeth are often very similar to each other. Following the suggested scanning steps lowers the chances of misalignment. The scanning method is the same for all anteriors.
When scanning intraorally, it might be more comfortable to have the scanner tip pointing towards the mesial instead of the distal. In this case, the surface indicators on the model will be incorrect until the Orientation is changed.
Optional additional scans
Evaluate your model. When you have long and straight anterior teeth, additional facial scans are sometimes needed to capture all of the data.
With the proximal or preparation in the centre of the circle, take 2 to 3 scans as you gradually rotate down the facial side of the tooth.

15.16 Scanning multiple anteriors

When scanning multiple anteriors and crossing the mid­line, start the scanning with the highest tooth number (Universal) or higher quadrant (ISO) to get the correct orientation.
In intraoral scanning it is sometimes more comfortable to scan with the scanner tip pointing towards the mesial instead of the distal. There are a couple of options for dealing with this situation.
Take the first scan with the scanner pointing in the correct direction. Turn the scanner around to a more comfortable position and retake the first scan.
Watch the model as it applies the second scan and ensure the scan is placed correctly. This will not work if there is insufficient data for the system to recognize the two scans as the same position. If the second scan aligns correctly, continue scanning in the normal pattern.
When crossing the mid-line, lingual scans are recommended for more data and fewer flat surfaces. After you turn the scanner around, pay attention to where the system places the next scan. Repeating a previous scan can help the system recognize that the scanner has been turned around. If the scan is placed in the wrong area, there may not be enough data on your model to turn the scanner around and more scans will be required.
Take the first scan of the higher tooth number with the scanner pointing towards the mesial or start with a lower tooth number. In this case, the surface indicators will be incorrect until you reach the tab, turn the model around when setting the Orientation.

16 ORIENTATION

16 ORIENTATION

Orientation is the selected model position for Autogenesis to propose the new restoration. Autogenesis in turn uses this set position as a starting point for cusp height and marginal ridges based on the adjacent teeth.
The first scan determines the initial positioning of the model.
Orientation affects two major aspects:
Design - Orientation plays a large part in Autogenesis and determining that the anatomy aligns with the adjacent teeth.
Milling - The path of insertion determines the Orientation needed for milling. In order for a restoration to mill out properly, the margin and axial walls must be visible from the occlusal view.
In most cases, these two factors can be accomplished with one Orientation and will only need minor adjustment. There are situations when greater adjustments to Orientation are required.

The central point of the orientation circle is the middle of the screen, which may or may not be the location of your prep. If the central point is not on your preparation, it can be a little confusing when rotating the model.
It is not necessary to centre the model on the preparation, but it can be helpful if you are new to rotating a 3D model or if you have multiple preparations. The example below shows a preparation with no distal neighbour, so the prep is not in the middle of the screen.

2. From the occlusal, check that the central groove is in alignment.
3. From the buccal, check that the marginal ridges are parallel to the marginal ridges of the adjacent dentition.

16.6 Resetting the orientation

The preview tooth is usually higher than the adjacent teeth. The proposal will drop down to align with the adjacent teeth during Autogenesis.
4. From the distal, check that the cusp tips are in parallel alignment
Since the preview tooth usually sits higher than the adjacent teeth, it will not follow the curve of spee.
