Maxillomandibular relationship record methods for computer-engineered complete dentures: a scoping review.

Area of Science:

• Dentistry
• Biomaterials Engineering
• Digital Health

Background:

• Accurate recording of the maxillomandibular relationship (MMR) is crucial for complete denture (CD) fabrication.
• Computer-aided design and manufacturing (CAD-CAM) technologies offer advancements in denture production.
• The digital workflow for complete dentures necessitates efficient and reliable MMR recording techniques.

Purpose of the Study:

• To conduct a scoping review identifying methods for recording the maxillomandibular relationship (MMR) in computer-aided designed and manufactured (CAD-CAM) complete dentures (CDs).
• To explore the digital workflow techniques used for MMR registration in CAD-CAM complete dentures.

Main Methods:

• A comprehensive scoping review adhering to PRISMA-ScR guidelines.
• Searched three major databases (PubMed, Scopus, Science Direct) for relevant clinical studies and reviews.
• Included studies assessed MMR recording techniques within a digital workflow for CAD-CAM complete dentures.

Main Results:

• Analysis of 10 studies revealed 4 commercial CAD-CAM denture systems and 3 innovative methods.
• Identified techniques can reduce the number of patient appointments to 2-4 visits.
• Three techniques, including two innovative ones, showed reduced procedural difficulty, independent of clinician expertise.

Conclusions:

• Both commercial and innovative MMR recording techniques enhance treatment predictability for CAD-CAM complete dentures.
• Effectiveness is noted, but successful implementation depends on the clinician's learning curve and patient's clinical status.
• Awareness of diverse MMR recording tools and techniques is essential for clinicians fabricating complete dentures.
