What is TMJ Total Joint Replacement?
Total temporomandibular joint (TMJ) replacement is the definitive surgical option for end-stage TMJ pathology when conservative therapy, arthrocentesis, arthroscopy, and discectomy have failed. Indications include bony or fibrous ankylosis, severe inflammatory arthritis (rheumatoid, psoriatic), avascular necrosis, condylar resorption (idiopathic or post-orthognathic), failed alloplastic implants from prior eras (silicone or Proplast-Teflon), and reconstruction following tumor resection or trauma.
Modern total joints use cobalt-chromium-molybdenum or titanium fossa components articulating with cobalt-chromium condylar heads on titanium ramus extensions. Patient-specific implants are designed from CT-derived virtual surgical planning using CAD/CAM technology, optimizing fit, occlusion, and ramus reconstruction. Stock implants offer cost advantages but limited customization.
Outcomes after total joint replacement demonstrate sustained pain reduction, improved maximal interincisal opening (MIO), and durable function with appropriate patient selection. Failures relate to infection, fibrous ankylosis around the implant, heterotopic ossification, and rare implant fracture. Lifelong follow-up monitors function, occlusion, and metal ion levels (cobalt-chromium serum levels in select cases).
Symptoms
Risk Factors
When to See a Doctor?
If you experience any of the following symptoms, seek medical attention promptly:
- Severe persistent TMJ pain not responding to splint therapy, physical therapy, or medications
- Progressive limited mouth opening
- Inability to chew or eat
- Worsening malocclusion or anterior open bite
- Documented condylar resorption on imaging
- Facial asymmetry from joint disease
- Failure of prior TMJ surgical procedures
- Severe inflammatory arthritis affecting TMJ function
- Reconstruction need after tumor resection
- Trauma with extensive condylar damage
- TMJ ankylosis with functional limitation
- Severe disability and quality-of-life impairment

Anaemia
Dahiliye (İç Hastalıkları)
Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.
Iron Deficiency Anaemia
Dahiliye (İç Hastalıkları)
Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.
Vitamin B12 Deficiency
Dahiliye (İç Hastalıkları)
Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.
Hypertension (High Blood Pressure) Management
Dahiliye (İç Hastalıkları)
Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.
Chronic Kidney Disease
Dahiliye (İç Hastalıkları)
Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.
Hepatitis B (HBV)
Dahiliye (İç Hastalıkları)
Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.
Hepatitis C (HCV)
Dahiliye (İç Hastalıkları)
Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.
Fatty Liver Disease
Dahiliye (İç Hastalıkları)
Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
