An overview of Vitallium subperiosteal implants in maxillary applications
Overview[edit]
Vitallium subperiosteal implants are a type of dental implant used primarily in cases where there is insufficient bone height or density in the maxilla to support traditional endosteal implants. These implants are custom-fabricated to fit directly onto the bone beneath the periosteum, providing a stable base for dental prosthetics.
Composition and Design[edit]
Vitallium is a biocompatible alloy composed primarily of cobalt, chromium, and molybdenum. This material is chosen for its strength, corrosion resistance, and compatibility with human tissues. The design of a subperiosteal implant involves creating a framework that rests on the bony ridge of the maxilla, with posts that protrude through the gingiva to support a dental prosthesis.
Indications[edit]
Subperiosteal implants are indicated in patients who have:
- Insufficient bone height or density in the maxilla
- Inability to undergo bone grafting procedures
- Previous failures with endosteal implants
Surgical Procedure[edit]
The placement of a Vitallium subperiosteal implant involves several steps:
Initial Assessment[edit]
A thorough clinical and radiographic assessment is performed to evaluate the patient's oral health and bone structure. CT scans or cone beam computed tomography (CBCT) may be used to create a detailed map of the maxillary bone.
Surgical Exposure[edit]
The maxillary bone is exposed by making an incision in the gingiva. The periosteum is carefully lifted to allow for the placement of the implant framework.
Implant Placement[edit]
The custom-fabricated Vitallium framework is placed onto the exposed bone. The posts of the implant protrude through the gingiva, ready to support a dental prosthesis.
Closure and Healing[edit]
The gingiva is sutured back into place, and the patient is allowed to heal. Healing times can vary, but typically range from several weeks to a few months.
Advantages and Disadvantages[edit]
Advantages[edit]
- Suitable for patients with insufficient bone for traditional implants
- Custom-fabricated to fit the patient's anatomy
- Can be placed without the need for bone grafting
Disadvantages[edit]
- More invasive than endosteal implants
- Longer healing time
- Potential for complications such as infection or implant failure
