Complete Over of Endosteal vs Subperiosteal Implants

Endosteal Implants vs Subperiosteal Implants

Dental implants are one of the best replacements for natural teeth. Their strength, longevity, and durability set them apart from other teeth replacements. However, more than one type of dental implant is available in the market. For example, endosteal implants, subperiosteal implants, and zygomatic implants. 

The following article explains the key differences between endosteal vs subperiosteal implants to help you decide which one is best for you. 

What is an Endosteal Implant?

The type of dental implants placed within the jaw are called endosteal implants. These are among the most commonly used implants in America. Endosteal implants are placed within the jaw bone because the bone is healthy and there is sufficient bone density.

The parts of an endosteal dental implant are:

  • A titanium screw – placed inside the jaw bone. This screw is often layered with a material known as hydroxyapatite. This is synthetic bone. It boosts the bond formation with the surrounding bone. 
  • An abutment – it is attached to the screw on one side and with the prosthetic crown on the other side. 
  • Crown – a crown is made of either porcelain, ceramic, or any other suitable material.

What is a Subperiosteal implant?

A subperiosteal implant is placed on the bone. When the bone is not dense enough to accommodate and support the implant, then it is placed above the bone and below the gums. 

The jaw bone is comparatively thin and deteriorated.

The parts of a subperiosteal implant are:

  • A metal frame – instead of a titanium screw – made of cobalt, chrome, vitallium, or molybdenum is used. This frame compensates for the lost bone height. It gives hope to people who have insufficient bone height. This is usually the case with patients who have lost their posterior teeth. In such a situation, the bone resorbs due to the prolonged absence of teeth.
  • An abutment
  • A crown 

Endosteal Implants vs Subperiosteal Implants

Here are the key differences of both types of implants:

Procedure

Let’s go through their placement procedure further to understand the differences between endosteal implants and subperiosteal implants.

What is the procedure for an endosteal implant?

The procedure of endosteal implants is slightly more invasive than the subperiosteal implants.

Firstly, the dentist cuts the gum to access the bone. Then, space is created in the bone via drilling. All this is performed under anesthesia so the patient does not feel any pain. 

Once the implantologist has created a hole in it, the titanium screw is placed. A temporary restoration may or may not be given to the patient. The process of osseointegration between the bone and the screw completes in about three months. Once the healing is complete without complications, the dentist calls the patient for another appointment after a few months.

In this appointment, the dentist adjusts the crown on the implant and gives post-op instructions.

What is the procedure for a subperiosteal implant?

A small cut is given on the gums for subperiosteal implants. This procedure is less overwhelming and invasive than that of the endosteal implant. While the patient’s gums are numb, the area beneath the gums is drilled. Here, the dentist places the metal frame. The gums will be sutured or stitched upon the metal frame. 

After a certain period, the gums heal. Then, one or more crowns are placed on top of it as per requirement.

Cost

Irrespective of the type of implant or dental procedure being considered, financial aspects play a major role.

What is the cost of an endosteal implant?

In New Jersey, an endosteal implant generally costs between $1000 to $3500.

What is the cost of a subperiosteal implant?

A subperiosteal implant costs between $2000 to $5000 for a single tooth in New Jersey. 

Healing Time

The healing time of both types of implants varies. An endosteal implant takes more time to heal than a subperiosteal implant. About 6 months are required for its complete healing. The process of osseointegration is involved in this case. 

Osseointegration refers to the bond formed between the bone and the screw placed within it. A successful osseointegration depicts the success of an endosteal implant. 

On the contrary, a subperiosteal implant requires minimal time to heal. This is because the bone is not disturbed, and the implant is placed over the bone. 

Stability and Durability

Endosteal implants are supported by bone, unlike the subperiosteal implants. Their inner bony support gives them an edge. Therefore, they are more stable and durable than the subperiosteal implants. A patient having an endosteal implant can resist the masticatory forces effectively. 

Subperiosteal implants are less stable than endosteal implants. Patients with subperiosteal implants should be careful with their diet specifically while consuming hard objects like fruits, nuts, etc. 

Suitability

Let’s see when it is suitable to place which type of implant. 

When would an endosteal implant be recommended for a patient?

An endosteal implant is recommended for a patient when:

  • Patients have adequate thickness or density of bone
  • Sufficient bone height is available
  • Single-tooth replacement is required
  • Optimal health of gums
  • Overall good health of the patient

When would a subperiosteal implant be recommended for a patient?

A subperiosteal implant is recommended for a patient when:

  • Insufficient bone height and density
  • Multiple teeth loss
  • Narrow bone
  • Patients who do not want a bone graft procedure before dental implant placement
  • Quick tooth replacement is required.

What are Zygomatic Implants?

In addition to endosteal and subperiosteal implants, there is a third type of implant known as a zygomatic implant. Zygomatic implants are placed in the cheekbones (also known as zygomatic bone). In this situation, the jaw bone of the patient is not sufficient to accommodate dental implants in them. 

They are comparatively difficult to place. They have the potential to last a lifetime if properly maintained.

Conclusion

This article explains the key differences between endosteal and subperiosteal implants. Dental implants can last a lifetime if they are maintained properly. Endosteal implants have a higher success rate, but subperiosteal implants are also effective if the formers are not an option.
