[Recording occlusal indicators. Introduction to occlusal surface materials and roughness]

Area of Science:

• Dental materials science
• Biomaterials engineering
• Occlusion analysis

Background:

• Accurate marking of occlusal contacts is crucial for dental restorations.
• Various materials are used, including foils, papers, and tapes.
• Surface properties and material interactions influence marking efficacy.

Purpose of the Study:

• To evaluate the quality and performance of different occlusal marking materials.
• To determine the influence of surface material and roughness on marking accuracy.
• To identify optimal materials for various dental substrate types.

Main Methods:

• Comparative analysis of 4 foils, 6 articulating papers, and 4 tapes.
• Assessment of marking quality based on surface material and roughness.
• Evaluation of material suitability for different dental substrates (plastics, ceramics, amalgam, gold-alloys).

Main Results:

• Plastic indicators colored best; ceramic indicators performed worst.
• Unpolished surfaces generally yielded better results than highly polished ones.
• Foils provided the most exact markings but were less suitable for smooth or rough surfaces.

Conclusions:

• Foils are precise but have limitations on specific dental materials.
• Thin articulating papers are preferable for smooth ceramics/amalgam and rough gold-alloys.
• Material selection should consider substrate properties and desired marking accuracy.
