Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

|Impacted Third Molar Tooth, Temporomandibular Disorder|
Dental procedures can cause jaw pain, discomfort and fatigue from opening the mouth too long or too wide, or by placing too much force on the jaw. (1-15) Opening too wide can also cause hyperextension of the jaw. During and after long dental procedures, patients frequently report jaw pain, fatigue, or discomfort. This pain and dysfunction characterizes temporomandibular disorders (TMD), which can be short-term or may become chronic. TMD occurrence is frequently associated with trauma from dental procedures, including 3rd molar extractions. (1-15) Also, dental procedures may aggravate pre-existing subclinical TMD symptoms. (16) When a downward force is placed on the patient's jaw to surgically remove the mandibular (lower) 3rd molars, the patient must tense his/her jaw muscles to oppose it. This can result in jaw pain, discomfort or fatigue, especially if the force is high or prolonged. Patients under moderate/deep sedation or general anesthesia cannot tense their muscles to counter this downward force to prevent injury to the jaw. Bite blocks hold the patient's mouth open but do nothing to counter this downward force on the jaw. Opening a patient's mouth too wide can cause jaw hyperextension; a long extraction procedure time can also lead to injury of the jaw. Currently, oral and maxillofacial surgeons (OMSs) when surgically removing 3rd molars (wisdom teeth) with moderate/deep sedation or general anesthesia have at least 2 dental assistants present. The first dental assistant provides suction and gives the surgical instruments to the surgeon. The second dental assistant is a certified anesthesia dental assistant who monitors the patient's vitals as well as oxygen and carbon dioxide levels while providing the patient with medications intravenously. This second dental assistant also inserts the bite block and then stands behind the chair and places their hands on both sides of the jaw to support it and oppose the downward force on the patient's jaw during the extractions. If additional intravenous medications are needed during the surgery, the surgery has to stop (lost time) and the OMS or the first dental assistant supports the jaw until the second dental assistant completes the medication administration. Based on clinical experience, the second dental assistant often experiences fatigue and pain in their hands, arms, neck and shoulders during long or difficult procedures, which can affect his/her ability to support the jaw. Given the second dental assistant's many duties and responsibilities, it is hard for the assistant to provide constant good jaw support while anticipating the direction and amount of force placed by the OMS on the patient's jaw during 3rd molar surgical removal. This may explain the finding that almost a quarter of new onset of TMD cases in young adults is associated with 3rd molar removal. This patient safety issue can be addressed during 3rd molar surgical removal by using a bite block to hold the mouth open and concurrently using a jaw support device under the jaw to provide a stable counter force to downward forces on the jaw, thus preventing jaw hyperextension and injury to the jaw. This would also free the second dental assistant from holding the jaw so he/she can concentrate on his/her other duties, which would improve patient safety. In this two-arm parallel randomized clinical trial design, 294 patients undergoing 3rd molar extractions with moderate/deep sedation or general anesthesia will be randomly allocated to Usual Care (UC) or Experimental Care (EC). Patients presenting for surgical removal of 3rd molars will be invited to participate in the study at the time of their oral surgery consult. The OMS will determine if the patient meets eligibility criteria, explain the study and invite them to participate. At the time of 3rd molar removal, the OMS and their dental assistants will follow their standard procedures for obtaining consent from patients for 3rd molar removal with moderate/deep sedation. In addition, they will confirm the patient's interest to participate in the study, ask if they have any questions an obtain consent. The jaw device will be placed for those who are randomized into the EC group. The OMS will follow their standard protocol for removal of the teeth. The only change will be that the dental assistant standing behind the chair will be present at all time to readjust the device position as needed or remove the device as indicated. The default in the case of device malfunction is for the device to fall away from the patient and the dental assistant will be immediately available to take over supporting the patient's jaw with their hands, which is one of their standard responsibilities when the device is not used. Patients will report temporomandibular disorders (TMD) pain via questionnaires at baseline and at the 1-, 3-, and 6-month follow-up time points via email, phone and/or text.
No Intervention: Usual Care (UC)
The study control is UC, which involves the dental assistant supporting the jaw during the extractions with concurrent use of a bite block.
Experimental: Experimental Care (EC)
The study intervention for EC is use of the Restful Jaw version 2 (RJ2) device, which supports the jaw during the extractions, with concurrent use of a bite block.
Device: - The Restful Jaw Device
The Restful Jaw Device is used to support the jaw during dental procedures including surgical removal of 3rd molars (wisdom teeth) with sedation. The device is designed to counter the downward forces placed on the mandible by clinicians during dental procedures and prevent jaw hyperextension (opening too wide) while providing a secure, stable jaw position. When 3rd molar teeth are surgically removed with sedation, a dental assistant stands behind the dental chair and supports the patient's jaw with both hands under the patient's jaw. This device replicates the dental assistant in holding the jaw during dental procedures.
