SUM3D/Millbox Object Type Guide
- 4 Minutos para Ler
The use of Object Type in SUM3D or MillBox is extremely important. The correct use of the object type in reference to the particular dental prosthesis will allow the correct associated camming information to me applied to the project .STL being imported. The user needs to take care in placing the correct object type with the right restoration.
In SUM3D/MillBox CAM you need to specify each Object Type as the correct dental restoration. This then applies the correct strategies and workflow operations to each different project type. Due to this specific task, the user must pay attention to the specific Object type picked when importing their restorative projects. You can also use Lab3dExplorer a free utility, within MillBox to analyze, and pre-sort your .stl files for milling.
Selecting the proper Object type is key in the workflow protocol for a successful outcome in Milling from the Machine. The user must pick the proper Object type from the list which opens, in order to properly attach the correct information to the .STL file being used.
Crown and Bridge Group: consisting of 10-Object Types
A thin covering of the coronal portion of the tooth usually without anatomic conformity.
2)Full Contour Crown
A full contour crown/coping - A structure derived from the full anatomic shape
3) Provisional Crown
A temporary crown placed on a tooth is provisional, meaning it temporarily stays in place as a placeholder until the final restoration is complete and placed permanently. Typically made from colored PMMA.
Framework Bridge: A set of one or more layered or milled ceramic restorations supported by a framework, used to replace one or more missing teeth.
Bridges are permanently placed in a individuals oral cavity.
5)Full Contour Bridge
Full contour means that restorations come in their final shape, with great occlusal detail.
A temporary bridge, placed on a bridge preparation is provisional, meaning it temporarily stays in place as a placeholder until the final restoration is complete and placed permanently.
A telescopic crown is defined as an artificial crown fabricated to fit over a coping or substructure.
The telescopic crown achieves parallelism of abutments using primary copings for a common path of insertion
An inlay fills in cavities and hollows in a tooth in the areas between the cusps.
Is an extra coronal restoration covering most of the occlusal surface and up to five-eighths of the surface tooth structure.
Veneers are thin coverings that are placed over the front (visible) part of the tooth. They look like natural teeth. Veneers can be used to correct a wide range of dental issues, such as: teeth that are stained and can't be whitened by bleaching.
Specialized Object Types:
In dentistry, an abutment is a connecting element. This is used in the context of a fixed bridge, partial removable dentures and in implants. The implant fixture is the screw-like component that is Osseo integrated
Hybrid abutment is an abutment with a titanium section that is against the dental implant and a ceramic section over it to hide the metal.
The tooth or implant that supports and retains a dental prosthesis. In an implant situation the abutment portion is from non engaging implant abutments.
The tooth or implant is designed with complete anatomic shape and conforms to the patients dental profile.
Anatomic Abutment Bridge
Overstructure/Bridge or Denture over a bar
Implant Retained Denture
Post and Core
A post and core crown is a type of dental restoration required where there is an inadequate amount of sound tooth tissue remaining to retain a conventional crown. A post is cemented into a prepared root canal, which retains a core restoration, which retains the final crown.
Within the framework of Millbox/SUM3D, the cam software automatically detects the following x curves and surfaces. Within the software these curve lists are created with specific requirements for each part. The most important information that is read automatically within the CAM software are the margin line, the insertion axis of the crown, the screw channel of an implant, the implant geometry, the interproximal space, as well as, the contact area of a crown, so that pin placement will be done automatically at the equator. All information for the CAM is created within the construction information file sent with the STL DATA. The construction information is referred to as the attached xml. meta-data.
Example:1 Automatically Detected curves and surfaces
- Margin line identified from Data
- Path of Insertion for Crown from Data
Example:2 Automatic Pin placement within the stock, white line represent the equator or the height of contour of the restoration (relative to 0 / 180 degrees). Support pins should be placed as close to this line as possible to minimize the creation of undercuts.
- Automatic pin placement line on the crown equator
Example: 3 Implant meta-data held within the construction information or xml. file from the CAD system.
- Screw channel direction and dimensions
- Red cap protection to prevent screw channels being accessed during the roughing cuts of the unit
- Emergence profile of the implant, is where the implant will touch the gingival tissue of the patient, and form to its contour and shape.
