Planning and workflow were model free and performed using 3Shape TRIOS and Dental System software. The case study describes the model free digital workflow used in the planning, placement and prosthodontic restoration of the lower right quadrant.

"On clinical examination, we can see a lingual crack and an occlusal-mesial leakage of the amalgam. Due to the large size of the defective restoration, the treatment choice is to use an indirect bonded restoration – veneerlay type," Dr. Édouard Lanoiselée. The case study describes the digital workflow for planning and placement of an e.max veneerlay on the lower left first molar.

Case describes a prosthodontic restoration of the lower right first premolar with a screw-retained implant supported crown. Planning driven by TRIOS implant scanning, software and 3Shape scan bodies. The case study describes the full digital workflow in the planning, immediate guided surgical placement and the prosthodontic restoration of the lower right first premolar.

Patient complained of pain and mobility from the right first premolar (tooth 44). Examination revealed class 2 mobility and deep periodontal pocketing localized to the tooth. The case study describes the full digital workflow in the planning, immediate guided surgical placement and the prosthodontic restoration of the lower right first premolar.

Patient is a 26-year old female that presented with 6 existing, 3-year old porcelain veneers and was unhappy with the appearance. They were too labially placed with a significant midline cant and the canines flared. The decision was made to replace the existing 6 porcelain veneers with 10 all ceramic veneers. The procedure was performed using a digital workflow including Smile Design and bis-acryllic temporary mock-up.

A 26 -year-old female (TV personality) looking to improve her smile. As a celebrity, the patient’s goal is to obtain the best smile possible without fixed appliances due to her public profile. The patient was presented with a treatment plan consisting of no. 12 clear aligners to be changed every two weeks. She was able to view the treatment on a video (3Shape Ortho Analyzer) including debonding.

Patient presented with mobile upper anterior teeth which protruded facially. Treatment called for a screw retained 4-unit layered zirconia bridge supported by 2 Co-Axis implants.

Patient diagnosed with Squamous Cell Carcinoma of his right premaxilla and nasal cavity days before his restorative treatment is scheduled. The successful case documents that the 3Shape TRIOS intraoral scanner was capable of scanning both teeth and soft tissue (a resected maxilla) with high accuracy and precision.

Female patient aged 62. The patient is healthy but with failing dentition in the upper maxilla, 11, 21, 12, 22. The patient would like to improve her functionality and oral esthetics.

Patient in his early 80s with a chief complaint of recurrent pain, discomfort and swelling from his lower dentition. Treatment called for provision of an immediate implant retained fixed provisional bridge.

Patient is suffering from the continuous decimation of her crown on the central incisor. Remaining stump has subgingival margins and the typical appearance of having suffered continued leaks.

This case describes an aesthetic and functional rehabilitation of an upper premolar. Dr. Nelson used the TRIOS® intraoral scanner and the Implant Studio® software for the implant planning and surgical guide design as well as Dental System™ for the making of the final prosthesis. Dr. Nelson says: “In the case presented here, the combination of TRIOS® and Implant Studio® with Dental System™ to manufacture the prosthesis has generated a predictability on the execution, from the correct positioning of the implant to the restoration placement.”

Male patient, 72 years old, with a 3 months prior extract from failed root canal treatment on supported bridge 13–22. Patient would like a fix prosthodontics for missing teeth.

Patient is 32-year old male suffering from multiple loss of teeth due to severe dental caries. Exposed root rests were all unusable as abutment teeth and remaining teeth were erupted and not in their own occlusal position. The treatment plan was divided into five phases. Dr. Lee says that “with the advent of dental CAD/CAM technology like Implant Studio®, we can now anticipate the position of the implants before surgery. And with this, immediately loaded implant prosthesis are much more precise and easier to place."

Dr. Lee has been chief dentist at the Jungplant Dental Office in Seoul since 2010. Many of Dr. Lee’s patients are elderly. This has provided Dr. Lee with extensive experience in working with full-mouth rehabilitation and partially edentulous cases. The treatment plan called for three phases. Each involved extensive surgery and restorative design. Dr. Lee says, “Implant Studio enables me to intuitively plan a surgery based on the prosthetic considerations. As this case illustrates, being able to virtually place and verify the implant position for the final prosthesis prior to surgery is extremely valuable.”

Dr. Tan presents three different types of cases. Each case uses 3Shape Implant Studio® and TRIOS® intraoral color scans for the implant planning and surgical guide design.<br /> Patient 1 is an upper lateral incisor replacement;<br /> Patient 2 is upper central incisor tooth replacement;<br /> Patient 3 is a patient requesting the replacement of teeth 46 and 47.

Female patient aged 42. Patient wants to replace old PFM crowns on #12, #22 as they have poor margins as well as close the gap between teeth #11 and #21. Upon stabilizing patient’s periodontal tissue, orthodontic treatment using a clear aligner created with 3Shape OrthoAnalyzer would be applied to close gap, a single visit restoration would be used to replace PFM crowns after.

The patient is a middle-aged man who had an old fibre-reinforced anterior bridge. The abutment teeth of the old bridge had severe caries and the structures of the bridge had also reached the end of their lifespan. The bridge was removed. Specialist Juha-Pekka Lyytikkä from the dental clinic Hammas-Pulssi extracted the hopeless teeth and placed three Xive 3.8 mm implants for the patient (areas of #14,12, 22). When the healing period was over, the construction of the final prosthesis was started.
