Summary
Corneal diseases cause significant blindness. Osteo-odonto-keratoprosthesis (OOKP) offers a sustainable solution for severe cases, restoring vision when corneal transplants fail.
Area of Science:
- Ophthalmology
- Regenerative Medicine
- Surgical Innovation
Background:
- Corneal diseases are a major global cause of blindness, second only to cataracts.
- Severe corneal damage often results from infections, inflammation, trauma, or autoimmune conditions.
- Standard corneal transplantation (penetrating keratoplasty) frequently fails in cases of severely compromised ocular surfaces.
Purpose of the Study:
- To highlight the challenges in treating severe corneal diseases.
- To present osteo-odonto-keratoprosthesis (OOKP) as a viable alternative for vision restoration.
- To showcase the successful application of OOKP in a specialized surgical setting.
Main Methods:
- Osteo-odonto-keratoprosthesis (OOKP) involves using a patient's own tooth and bone to create an artificial cornea.
- This complex procedure requires close collaboration between ophthalmology and maxillofacial surgery teams.
- OOKP is indicated for patients with bilateral dry eye and severe corneal pathologies unresponsive to other treatments.
Main Results:
- OOKP provides a sustainable solution for vision restoration in patients with severe corneal compromise.
- The technique enables patients, particularly those with bilateral dry eye from conditions like burns or cicatricial pemphigoid, to regain optimal visual acuity.
- The University Hospital of Liège regularly performs OOKP, a procedure practiced by few teams worldwide.
Conclusions:
- Osteo-odonto-keratoprosthesis (OOKP) is a critical treatment option for end-stage corneal disease.
- Successful OOKP outcomes depend on multidisciplinary surgical expertise.
- This innovative approach offers hope for vision recovery in previously untreatable cases.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
