Intraoral Scans Alignment in Single Edentulous Arch Cases

Area of Science:

• Dental prosthetics
• Digital dentistry
• Maxillofacial technology

Background:

• Accurate maxillo-mandibular relationship registration is crucial for removable denture fabrication.
• Traditional methods can be time-consuming and prone to errors.
• Intraoral scanning offers a digital alternative for capturing dental anatomy.

Purpose of the Study:

• To present a novel technique combining intraoral and extraoral scanning for removable denture fabrication.
• To ensure precise alignment of intraoral scans according to maxillo-mandibular relationships.
• To facilitate the digital transfer of all necessary information for tooth arrangement.

Main Methods:

• The technique involves intraoral and extraoral scanning of the occlusion rim.
• This approach captures the precise maxillo-mandibular relationships.
• All data is transferred to a digital workflow for tooth arrangement.

Main Results:

• The presented technique allows for accurate intraoral scan alignment.
• It enables the seamless transfer of occlusion rim data for digital denture design.
• The method is particularly effective for single edentulous arch cases, especially the mandible.

Conclusions:

• This combined scanning technique enhances the digital workflow for removable denture fabrication.
• It improves the accuracy of maxillo-mandibular relationship registration.
• The technique offers a viable solution for digital denture workflows, especially for edentulous mandibles.
