The aims of this observational study are to evaluate the trueness of two different digital occlusal analyzers; handheld occlusal analyzer versus intraoral scanner in comparison to conventional methods in identifying true occlusal contacts and to evaluate inter-examiner reliability of two examiners independently analyzing occlusal contacts.
Evaluate the trueness of two different digital occlusal analyzers; handheld occlusal analyzer (occlusense) versus intraoral scanner (Medit i700-medit occlusal analyzer) in comparison to conventional methods (8 um articulating paper) in identifying true occlusal contacts and to evaluate inter-examiner reliability of two examiners independently analyzing occlusal contacts.

| Measure | Description | Time Frame |
|---|---|---|
| Evaluation of trueness | Trueness is defined as the closeness of the measurement to the real size of an object. The trueness of handheld occlusal analyzers (occlusense) versus intraoral scanners (medit occlusal analyzer) will be evaluated in comparison to conventional methods (8 um articulating paper). | 4 months |
| Measure | Description | Time Frame |
|---|---|---|
| Inter-examiner reliability | Two examiners will record independently the interocclusal contacts for all the different groups, classifying them in a dichotomy variable (yes/no) contact or not per tooth. Then, the inter-examiner's reliability will be calculated. | 4 months |
