Choosing the denture occlusion - A Systematic review.

Area of Science:

• Dentistry
• Prosthodontics
• Biomaterials

Background:

• Complete dentures are crucial for restoring function and aesthetics in edentulous patients.
• The choice of occlusal scheme significantly impacts denture stability, retention, and patient satisfaction.

Purpose of the Study:

• To systematically review and evaluate evidence comparing different occlusal schemes for complete denture prostheses.
• To determine the superiority of specific occlusal schemes, including bilateral balance occlusion (BBO), lingual occlusion (LO), canine guided occlusion (CG), and posterior group function occlusion (PGFO).

Main Methods:

• A systematic review adhering to PRISMA guidelines was conducted.
• Seventeen studies were included after screening 1896 articles.
• Data on occlusal schemes, methodologies, and outcomes were extracted, and risk of bias was assessed using RoB2.0 and robvis tools.

Main Results:

• No statistically significant difference in clinical outcomes was found between various occlusal schemes when using anatomic tooth forms.
• Both objective and subjective evaluations indicated comparable results across different schemes.
• Risk of bias analysis was performed on the included studies.

Conclusions:

• Anatomic tooth forms do not confer superiority to any single occlusal scheme.
• Unbalanced occlusal schemes can achieve satisfactory clinical outcomes comparable to balanced schemes.
• Alveolar ridge classification plays a significant role in the selection and success of an occlusal scheme.
