Virtual Implant Planning and Surgical Guide for Single Implant Placement Fabricated from a Digital Diagnostic Cast, 2-dimensional Radiographic Imaging, and an Open-source Program: A Dental Technique.

A technique for virtually planning single implant by combining an intraoral digital scan, an opensource computer-aided design software program, bone sounding, and 2-dimensional radiographic imaging is described. The surgical implant guide is fabricated by using additive manufacturing technologies. Furthermore, the surgical implant guide positioned in the patient's mouth is used to radiographically verify the estimated mesio-distal implant angulation before proceeding with the surgical intervention and modified, if necessary. When a cone bean computed tomography scan is not available, this technique eases implant planning procedures and minimize possible surgical complications.

Use of an optical jaw-tracking system to record mandibular motion for treatment planning and designing interim and definitive prostheses: A dental technique.

Optical jaw-tracking systems can record mandibular motion during the various treatment phases. Also, computer-aided design programs facilitate the integration of a patient's digital information, including recorded mandibular motion, into the design of interim and definitive prostheses. A technique to fabricate a complete mouth implant-supported rehabilitation by using mandibular motion captured with an optical jaw-tracking system is described. The mandibular motion recordings obtained before the treatment are combined with the interim restorations to perform a diagnostic waxing, design the computer-guided implant plan, and fabricate maxillary and mandibular screw-retained implant-supported interim and definitive prostheses. The process allows occlusal adjustments by using the patient's mandibular motion and facilitates the prosthetic design process, minimizing chair time at delivery.

A Technique to Correct Anterior-Posterior Tooth Discrepancy for a Maxillary Immediate Complete Denture.

This article describes a chairside technique to correct inappropriate occlusal vertical dimension as well as the inaccurate anterior-posterior tooth set-up of a maxillary immediate complete denture. When fabricating an immediate denture, the inability of a wax-denture trial and the potential for unpredictable complications during surgery, compromised esthetics and function of an immediate complete denture may pose a clinical problem, which needs instant correction. The technique described can provide an alternative method to correct and deliver a definitive immediate complete denture on the day of surgery.
