Evaluation of Using Patient Specific Zirconium Dioxide Implant Versus Patient Specific Titanium Implant in Treatment of Chronic Condylar Dislocation

Cairo University (CU)

Status: Completed

Conditions: Recurrent Dislocation of Temporomandibular Joint (Disorder)

Treatments: Device: eminoplasty with patient specific Zirconium dioxide onlay implant

Study type: Interventional

Funder types: Other

Identifiers

NCT05377593

OMFS 3-3-4

Details and patient eligibility

About

Alternate hypothesis that treatment of Tempromandibular joint dislocation with Zirconium Dioxide eminoplasty will be more efficient than using titanium onlays in terms of decreasing maximum inter incisal distance and providing better soft tissue response and post-operative patient satisfaction.

Enrollment: 14 patients

Sex: All

Ages: 18 to 48 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Patient with recurrent dislocation with maximum inter incisal opening over 55mm
• Long-standing dislocation of the TMJ involving both fixation for more than 3 weeks and the failure of manual reduction
• Failure of conservative strategies such as orientation to self-limit jaw movement and the use of a chin-cap or bandage
• Both sexes
• Age between 18 and 48 years.
• Highly motivated patients.

Exclusion criteria

• Post-menopausal females with osteoporosis
• Patient with uncontrolled systemic disease
• pregnancy
• psychological disorders, drug or alcohol dependency
• Known allergies or sensitivities to dental materials, including Zirconia, Titanium or general anesthetic agents
• Inability to return for follow up visits.
• Refusal of participation from the patient
