Full-Arch Implant-Supported Rehabilitation Using Reverse Scan Technique: A Case Report.

Area of Science:

• Dental Implantology
• Prosthodontics
• Digital Dentistry

Background:

• Significant bone loss and mobility in remaining teeth often necessitate full-mouth extraction and rehabilitation.
• Immediate loading prostheses following dental implant placement offer functional and aesthetic benefits.
• Accurate digital impression techniques are crucial for predictable prosthetic outcomes.

Purpose of the Study:

• To report the successful application of the reverse scan technique in a full-mouth rehabilitation case.
• To evaluate the efficacy of the reverse scan technique for capturing implant positions and prosthesis design.
• To assess the impact of the reverse scan technique on patient comfort and clinical efficiency.

Main Methods:

• Extraction of compromised teeth, placement of 4 implants in each jaw, and immediate loading with an interim prosthesis.
• Utilizing the reverse scan technique with light silicone, reverse scan bodies, and extraoral scanning post-osseointegration.
• Fabrication of final prostheses using titanium frames with monolithic zirconia (maxilla) and zirconia crowns with composite gingiva (mandible).

Main Results:

• Successful capture of implant positions, soft tissue profiles, and prosthesis shapes using the reverse scan technique.
• High-quality final prostheses with excellent fit, aesthetics, and occlusion were delivered.
• The reverse scan technique contributed to enhanced patient comfort and reduced chair time.

Conclusions:

• The reverse scan technique is a viable and effective method for complex full-mouth implant rehabilitations.
• This digital workflow streamlines the prosthetic process, ensuring predictable and high-quality outcomes.
• The technique offers advantages in terms of efficiency and patient experience compared to conventional methods.
