Bone Reduction
Computer guided implant planning was done for the mandible following "virtual extraction" of the existing anterior teeth. The coronal level of the implants were aligned approximately 4mm sub-crestal.
A bone supported surgical guide was designed to seat on the mandible following bone reduction.
The mandibular jaw in the format of a Dicom file was converted (following virtual tooth extraction & bone reduction) to "STL" format & printed using 3D stereolithography. The surgical guide was printed & correct seating verified on the printed model.
The reduction guide was 3D printed & evaluated on the jawbone model prior to reduction.
With the aid of the reduction guide the clinician can "duplicate" the bone reduction in accordance to the planning.
The levelling of bone will facilitate simple guided implant placement.

4 年We just published an article on this very topic... having developed the concept of the bone reduction template almost 20 years ago, it’s great to see how our latest technology allows more clinicians to see the benefits of a guided approach. One caveat - my best advice is to plan the implant locations FIRST... restoratively-driven of course, and then level the bone so all implants will be on the same plane. Stackable or non-stackable.... it’s a great way to achieve success with fixed or removable implant-supported restorations... thanks for sharing and helping to educate the world!! ????
