An eposteal implant, also known as a subperiosteal implant, is a dental implant that is placed on top of the jawbone instead of being buried inside it. This type of implant is used when there isn't enough bone available for direct implantation, or when a patient is at high risk for bone resorption. The eposteal implant rests directly on the gums and the posts of a metal framework that protrudes through the gums to support the artificial tooth.
History and Development
The eposteal implant was developed in the mid-1950s by Dr. Nissen and Dr. Gershkowitz, who were pioneers in the field of oral surgery. Initially, eposteal implants were placed in the mandible, which is the lower jaw, but they have also been used in the maxilla, which is the upper jaw.
How are Eposteal Implants Placed?
During an eposteal implantation procedure, the dentist starts by making a small incision in the gums to expose the jawbone. An incision is also made in the mucosa, the thin layer of tissue that covers the jaw. The dentist then drills a hole into the bone where the implant will be placed. A guide wire is inserted through the hole to aid in the precise placement of the implant. The implant is then fitted with a metal framework that will support the artificial tooth.
Types of eposteal Implants
There are two main types of eposteal implants: removable and fixed. Removable eposteal implants are inserted into the mouth and can be taken out for cleaning. Fixed eposteal implants are cemented into place and are not intended to be removed by the patient.
Benefits of Eposteal Implants
Eposteal implants offer several benefits, including:
- Immediate Function: Unlike some other implant types, eposteal implants can be placed and restored at the same time, allowing patients to regain function soon after surgery.
- Minimal Bone Reduction: Since the implant is placed on top of the bone, it requires less bone reduction than other implant types, which can be beneficial for patients with insufficient bone.
- Easy to Maintain: eposteal implants are relatively simple to clean and maintain, which can contribute to long-term oral health.
- Affordable:.eposteal implant procedures are typically less costly than other implant procedures, making them an affordable option for many patients.
Complications and Limitations
While eposteal implants are generally safe and effective, they do carry some risks and limitations. Some potential complications include:
- Infection: Like all dental procedures, eposteal implant placement carries a risk of infection, which may require antibiotics or further treatment.
- Bone Resorption: In some cases, the bone beneath the eposteal implant may resorb, which can occur whether or not the implant is removed.
- Limited to certain Cases: eposteal implants are typically not recommended for people with large amounts of bone or for those who need a significant amount of support for thejaw.
Future of Eposteal Implants
As technology and techniques advance, eposteal implants may become more commonly used and may offer even greater benefits in the future. For example, the development of improved implant materials and the adoption of computer-guided surgery could make eposteal implant placement more precise and controlled.
Getting an eposteal implant
If you think you might be a candidate for an eposteal implant, it's important to consult with a qualified oral surgeon who specializes in tooth replacement and implantology. Your dentist will assess your medical history, evaluate your dental needs, and determine whether an eposteal implant is the right choice for you.
##Eposteal implants are a type of dental implant that can be a good option for patients with insufficient bone or for those who are at high risk for bone resorption. They offer immediate function, reduced bone preparation, and ease of maintenance, although they also carry certain risks and limitations. Discussing all aspects of the procedure with your dentist, including the potential benefits, risks, and costs, is crucial before making a decision.
