The Gelb appliance is made in the lower jaw, covering only the premolar and molar teeth. It is used to correct mandibular displacement, reduce TMJ [temporomandibular joint] dysfunction and oral/facial pain, and to provide occlusal stability with the patient's natural dentition serving as the anterior guidance.

OBS

The appliance is named after Dr. Harold Gelb, the orthodontist who introduced it.

OBS

MORA appliance: The word "appliance" in this term is redundant, since the "A" in the acronym "MORA" stands for "appliance."

OBS

Some authors consider the term "mandibular orthopedic repositioning appliance" to be a synonym of "Gelb splint", while others think the MORA is a type of Gelb splint.
