Occlusal Splints

Brief summary
To compare the accuracy of the occlusal splints made by conventional impression and milled with the splint made by intraoral scanner and milled.
Detailed description
Forty participants received two different occlusal devices from two different workflows (fully conventional and fully digital). Every splint was scanned before and after the occlusal adjustments in order to compare the volumetric changes. Furthermore, the scans were compared in a software Geomagic® Control X calculates and measures the distance from every surface point from the initial dataset (occlusal devices before adjustment) to the final dataset (occlusal device after adjustment).
Interventions
OTHEROcclusal Splints Analogic-Analogic
Take a conventional impression to the patient and conventional fabrication of the splint.
OTHEROcclusal Splints Analogic-Digital
Take a conventional impression to the patient and digital fabrication of the splint.
OTHEROcclusal Splints Digital-Digital
Take a digital impression to the patient and digital fabrication of the splint.

Intervention model description
This clinical study has three arms of equal size: occlusal splints made by conventional impression and conventional fabrication (Group 1), occlusal splints made by conventional impression and digital design and fabrication (Group 2), and occlusal splints performed by intra-oral scanner and digital design and fabrication (Group 3). Otherwise, the allocation of each subject to each group will be done at random by a list made with specialized software until the sample will be fulfilled when the patient is recruited.

Exclusion criteria
* Pregnant patients. * Patients with removable prostheses. * Patients with fixed prostheses between six to six in both arches. * Patients with partial edentulism, do not maintain until first molar in both arches. * Patients with Temporomandibular Disorders (TMD): articular noises, pain on palpation, limited opening.

| Measure | Time frame | Description |
|---|---|---|
| Volumetric changes assessed in Root Mean Square (RMS) | 1 week | The software of automatically graphical comparisons called Geomagic® Control X (Geomagic Inc., 3D Systems Inc., USA) will be used to calculate the accuracy by measuring the distance (positive or negative) from every surface point from the initial dataset (occlusal devices before adjustment) to the final dataset (occlusal device after adjustment). This approach will give us the mean of the simple arithmetic difference. |
