What is Zygomatic Implant?
Zygomatic implants were introduced by P-I Brånemark in 1989 for maxillary reconstruction following oncologic surgery and have since been adapted for severely atrophic edentulous maxillae. The implants are 30-55 mm long titanium fixtures placed through the maxillary alveolar ridge, traversing the maxillary sinus, and anchored in the zygomatic bone. Two zygomatic implants in the posterior maxilla, combined with two anterior conventional implants (Quad zygoma uses four zygomatics for severely atrophic cases), support a fixed full-arch prosthesis.
Indications include severely atrophic edentulous maxilla with insufficient alveolar bone for conventional implants or sinus floor elevation, failed prior implant treatment, post-oncologic maxillary defects, post-trauma maxillary deficiency, and avoidance of extensive bone grafting and prolonged treatment timelines. The technique allows immediate or early loading with fixed provisional prosthesis, eliminating the need for staged grafting.
Treatment workflow includes CBCT-based virtual surgical planning, anesthesia (general or sedation), maxillary crestal incision with subperiosteal flap elevation, anterior implant placement, sinus elevation or sinus slot for zygoma implant trajectory, zygomatic implant placement, prosthetic loading typically immediate or 24-72 hours later, and lifelong maintenance. Reported success rates exceed 95% at 10 years. Complications include sinusitis (most common), oroantral communication, paresthesia, infection, and rare orbital complications. Specialized surgical training is essential.

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.
