ACCESS STUDY

Dr. Jaemin Lee

Immediate loading implant surgery
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."
ACCESS STUDY

Dr. Jaemin Lee

Full mouth rehabilitation
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.”
ACCESS STUDY

Dr. Philip Tan

Benefits of guided surgery
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.

- Patient 1 is an upper lateral incisor replacement;
- Patient 2 is upper central incisor tooth replacement;
- Patient 3 is a patient requesting the replacement of teeth 46 and 47.

Dr. Jaemin Lee

Restorative and orthodontic interdisciplinary treatment
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.
ACCESS STUDY

Dr. Jonathan L. Ferencz

Anterior aesthetic veneers using a digital workflow
A 70-year-old patient presented with a diastema and failed composite restorations to correct excessive tooth wear and incisal chipping on teeth #8 and #9. The risks of working in the aesthetic zone without a reduction guide are either under- or overprepping the natural teeth. One solution would be a virtual 3D-printed reduction guide that is delivered with the 3D-printed diagnostic wax-up model. Another solution would be to design the intraoral scanner software with the ability to compare the preparation to the virtual diagnostic wax-up and identify areas that are underprepared. Digital technologies eliminate the guesswork and inherent inaccuracies of analog processes and improve clinical workflows and efficiencies.
ACCESS STUDY

Dr. Andre Schertel

Same day restoration of an upper lateral incisor
Female patient in her late 70’s, healthy, presented for an urgent appointment due to a broken anterior tooth. The patient has a Class 2 Div. 2 dentition with a very deep bite and traumatic occlusion. Her remaining upper anterior teeth have advanced palatal wear and chipping of the anterior edges. The patient wears a lower partial denture which was recently replaced. She chose to proceed with the e.max milled crown due to time constraints and her need for a stronger restoration. She agreed to consider a comprehensive treatment approach.
ACCESS STUDY

Dr. George Kouveliotis

Complete dentures using a full digital protocol
A 56-year-old female edentulous patient was referred after two mandible implant placements. For a completely edentulous patient, a complete denture is chosen as the main prosthetic treatment option. The mucostatic concept protocol should be considered and followed during digital scanning. This digital protocol allows for all the clinical steps to be performed in a single visit. The treatment plan called for a maxillary complete denture and implant-retained overdenture in the mandible.
