Full Mouth Rehabilitation with Modeless Implant Restoration using a Two-step Surgical Guide System: A Case Report

Abstract

As digital dentistry has become widespread and increasingly popular in clinical practice, various attempts have been made to use digital technologies for dental treatment. Implant surgical guides that use these digital technologies have been widely used in recent implant surgeries. The seating and stability of implant surgical guides are essential to accurately transfer the planned surgery into the oral cavity. This case study aimed to explore the two-step surgical guide system to increase the stability of implant surgical guides for implant surgery in a patient with full extraction. In addition, this study attempted to report a clinical case in which fixed prosthetic restoration was completed by converting mucosal-supported surgical guides into tooth-and mucosal-supported surgical guides, and maintaining the vertical dimension through intraoral scanning.

Guide Surgery Using the Dual Optical Scan Method in a Patient with Distal Extension Base: A Case Report

“…Even in the presence of residual teeth, it is difficult to superimpose CBCT and model data if they exist only on one side, and it is advantageous to superimpose when there is at least one tooth on both sides. 8 If there are an insufficient number of teeth to fit the CBCT data, the dual-scan method is commonly used. However, in this case, a denture-type radiographic stent, which is used in the standard dual-scan method, was not used.…”
