简要总结
Statement of the Problem:
To create optimum maxillomandibular relationships, ease discomfort, and restore function, occlusal devices are used, therefore, these devices are of great importance in the field of prosthodontics.
Literature is scarce regarding the effect of various methods used in locating centric relation on muscle activity, in addition to which method is most accepted by the patients for whom centric relation is being located.
Null hypothesis:
There will be no difference in Masseter and Anterior Temporalis muscles activity and patient satisfaction after using the Leaf Gauge, The Lucia Jig and the Kois Deprogrammer.
详细描述
Research Question:
Which of the investigated methods will result in lower masseter and anterior temporalis muscles activity reading after locating centric relation in healthy adults, and will be more accepted by the patient?
Rationale for Carrying out the Trial: For the patient:
The results of the trial will identify the most effective and patient friendly method for locating a centric position, which instructions are easy to follow and apply. Furthermore, reaching a centric position, using one of the investigated methods, will help ensure orthopedic stability before, during and after the treatment process.
For the dentist:
