Oral implantology :: Cortico-Basal Implants

Cortico-basal implants are intraosseous implants based on a concept that differs from conventional intraosseous implant systems. While traditional implants are placed in the spongious (trabecular) bone and typically require a biological healing period for osseointegration prior to prosthetic restoration, cortico-basal implants are designed to engage and anchor directly into the cortical layer of the bone. This provides immediate primary stability and allows for immediate prosthetic loading.In practice, the treatment is completed within 3 to 5 days depending on the complexity of the case. On the first day, the implants are placed and the impression is taken. The laboratory phase for fabricating the bridge takes between 3 and 5 days, depending on the type of construction, its complexity, and the laboratory’s workload.



Treatment in 2010 – A male patient, approximately 30 years old, with a completely edentulous mandible. He did not wish to wear a full removable denture. 



X-ray in 2025 – Slight bone resorption, which is normal after 15 years of functional loading of the implants with the bridge. The patient reports no complaints and maintains normal chewing function. 


Another case of a completely edentulous mandible in a young patient, approximately 40 years of age. He had a worn lower full denture that caused significant discomfort.





As seen on the orthopantomogram, nine cortico-basal implants were placed.

The patient has an upper full denture, which he stabilizes with adhesive (Corega) and feels relatively comfortable with. For this reason, I began the treatment with the lower jaw. Treatment of the upper jaw will follow using the same approach.
