Trial Title: Restoring Masticatory Function to Treat Chronic Pain

Study Design Characteristics:
- Allocation: RANDOMIZED

- Masking: TRIPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Completely dentate (except for the third molars; including if they were treated before enrollment by conventional or implant-supported fixed prosthesis allowing similar potential comfortable chewing on both sides)~* Normal Angle Class I occlusion~* Self-reported pain-intensity scores from 4 to 9 in a 0-10 visual analogue scale (VAS) or numerical pain rating scale (NRS).~* Chronic (over 6 months) joint and/or muscle pain, according to diagnostic criteria for temporomandibular disorders (DC/TMD), for which they had requested therapy~Exclusion Criteria:~* Psychosis~* Major depression~* Substance abuse~* Cognitive impairment~* Addiction to morphine or derivates~* Litigation or asking for disability/retirement compensation for chronic pain~* Dental care professionals~* Orthodontic therapy during the last 2 years~* Patients with any pain that is more severe, in the same location as, or cannot be clearly distinguished from TMD pain~* Individuals for whom minimally invasive occlusal adjustment could not achieve occlusal equilibration, including: Over 2 mm of difference between the maximal intercuspal position and the centric occlusion or over 4 mm of difference between upper and lower archs (or over 2mm on at less one side) measured: between the mesial fosses of first upper premolars with respect the buccal cusps of the first lower premolars; and/or between the mesiopalatal cusp of the first upper molars respect to the central (mesial) fossae of the first lower molar.~* Severe periodontal disease with grade 3 mobility

Study Arms:
- Occlusal adjustment therapy (Type: EXPERIMENTAL): Occlusal adjustment therapy consists of the elimination of premature tooth contacts during retruded jaw closure, and the reduction of the steeper lateral anterior guidance; the magnitude of this alteration will be estimated by the following equation: (right condylar path) × (left anterior guidance) = (left condylar path) × (right anterior guidance). A resin-composite, placed mainly in the canine tooth, can be used to increases the flatter lateral guidance on the habitual chewing side; overcorrection is expected to compensate for a masticatory preference on the opposite side to the handedness.
- Placebo occlusal adjustment therapy (Type: PLACEBO_COMPARATOR): Placebo occlusal adjustment will take place in a manner identical to the real adjustment. However, a specially fabricated inactive rotary instrument will be used, and no enamel will be removed.

Based on this trial design, predict the completion outcome and termination type (if applicable).
