Thanks to the open STL data, the scanned files can be sent to any dental laboratory for de- sign work. This is the world’s first dental unit integrated intraoral scanner that can also be connected to a laptop. “The scanner has only one cable, so it is extremely easy to move from oneplacetoanother,forexamplebe- tween different treatment rooms or clinics”, says Product Manager Petri Kajander. “In addition, the scanner is delivered with a laptop, so the device can be flexibly shared between different users. In other words, Planmeca PlanScan offers value for your investment: it is not a deviceforjustonedentistbutcanbe used by the entire clinic.” The scanner utilises blue laser technique. It projects a pattern on the surface of the teeth and then analysesitfromdifferentdirections while calculating distances. In this way, the device is able to calculate a model that is extremely accurate. “You can view the result as a real- time video image. The video record- ing and the dental surface identifi- cation algorithm make the device extremely flexible to use. Thanks to these features, you can pause the scanning at any time and continue later on at any point from where data is already available.” The scanner includes a range of exchangeable tips in various sizes, the smallest of these facilitating ac- cess to the posterior parts, particu- larly with small children and trauma patients. The tips can be au- toclaved for efficient infection con- trol. In addition, the scanner is ex- tremely durable since it has no othermovingpartsinsideexceptfor a fan that removes warm air. “Thus, the device stays calibrated and is notsubjecttomechanicalwear”,ex- plains Kajander. Planmeca PlanCAD Easy– efficient design tool for prosthetics Planmeca also offers dentists a new kind of open software solution for 3-D design. Planmeca PlanCAD Easy is seamlessly integrated in Planmeca Romexis software and it is a user-friendly design tool for the design of inlays, onlays, veneers, crowns and bridges. “The software runs on the so- called floating licence basis. This means that it is not tied to just one computer or workstation, but the work is saved on the Planmeca Romexis server. In this way, the scanning station can be used only for scanning, while another work- station is used for the actual design work. This is a truly unique feature, which allows work to be continued straight away on another computer, while the scanner is freed for more productive operation”, says Kajan- der. Every dentist designing his or her own prosthetic works will also face cases that require assistance from a dental laboratory. For this reason, Planmeca’s system utilises an open STL file format that allows theworktobesentimmediatelytoa partner via the Planmeca Romexis Cloud service. SincePlanmecaPlanCADEasyis integrated in Planmeca Romexis software, soft tissue scans can also be conveniently paired with the pa- tient’s CBCT image. This combined data provides valuable information for implant planning, for example, because in addition to the soft tis- sues, it visualises the crown that is designed for the occlusion. This fa- cilitates the planning of the implant screw’s location. The Planmeca PlanCAD Easy workflow from preparation to the finished result includes just five easy stages: work description, scan- ning,markingofthemarginline,au- tomatic design, and sending the worktothemill.“Oncetheworkhas been sent to the mill, it is trans- ferred there in its entirety and the mill’s computer finishes the work. In this way, the software and scan- ner are immediately freed for a new assignment.” The software is very user- friendly. All design phases are saved automatically, and if further impressions are needed, previous phases can be returned to flexibly. Theautomaticdesignsoftwareauto- matically takes into account the ad- jacent teeth’s cusps and marginal ridge in addition to the contact strengths defined by the user. This creates a design that always fits its surroundings. Planmeca PlanMill 40–fast and precise milling unit for dental clinics Planmeca PlanMill 40 is an ex- tremely precise four-axis milling unit operating under the control of its own computer. The device is suit- ableforalltheindicationsofasingle tooth, in other words for the milling of crowns, inlays, onlays and ve- neers. The mill can manage bridges ofuptofiveunitstotheposteriorand three units to the anterior area. Sincethemillhandlesthemilled pieces completely independently, asmanyasseveraldozenpiecescan be sent to the mill at a time. In addi- tion, the device tells which block size, colour and material should be used,soanymemberofthestaffcan place the block in the mill. “This saves everyone’s working time. The dentist does not need add the block himself, but anyone can do it”, says Kajander. The mill has a six-tool exchange mechanism, and it changes tools in- dependently according to different job requirements. In addition, the device mills different materials ac- cording to their properties. For ex- ample, it knows how to gently han- dle delicate ceramics in work phases that require precision. “If you force the material, it may break prematurely. Even the smallest hairline crack in the material can lead to a cemented piece breaking when pressure is applied on it.” Also, the maintenance of the de- viceiscare-free.Themill’sowncom- puter calculates the service life of thetools,monitorswearandreports on them via the user interface.

Planmeca PlanScan Lab scan- ner is an accurate desktop scanner utilisingbluelightforscanninggyp- sum models and impressions. The device scans gypsum models fast andeffortlesslywithanaccuracyof 15 micrometres. Designing takes place in the open Planmeca PlanCAD Premium laboratory software, which can be used for the design of all prosthetic pieces,rangingfromone-toothunits tofull-archstructures.Thesoftware can also be used to design individ- ual abutments, implant bridges and bars for cemented and screwed so- lutions. Designing begins with defining the margin line, after which the path of insertion is selected and the structure designed. Several auto- matic functions assist in the design work, and as the design progresses, the software shows the contact ar- eas, material thickness and dis- tance to the antagonist or adjacent tooth. A diagnostic wax-up made in the laboratory or anatomic models savedinthesoftwarecanbeutilised in the design work. The software has an Order Man- ager page that brings efficiency to the workflow by reporting the stage of each work. In this way, several work orders can be entered in the software in one go.
