People often ask me this question. So, I thought why don’t I answer it in detail here? So here it goes! The cost of acquiring implants depends, among many other things, on the number of implants installed. It is an important term in the sum for cost of dental implant treatment. The number of implants required to support your teeth varies from case to case.

  • Replacing one or two missing adjacent teeth: If you are replacing only one or two adjacent teeth a single implant can easily support a small partial denture or bridge.
  • Replacing complete dentition with implants: on the other hand, if you need to replace all the teeth in a jaw with the help of a complete denture, at least 4 implants in each jaw are required to provide satisfactory results. This type of prosthesis is known as an all on 4 supported denture. Depending on the specifics of the case, six or even eight implants may be used in the upper jaw, possibly, five or seven in the lower jaw. The number of implants required for a complete jaw is a rather ‘technical’ decision. The number of implants, their locations and angulation all depend on the condition of the jaw bone.

An important consideration is that the bone should have sufficient strength at the proposed locations of implants. If bone is found to be deficient in quality or quantity, it may have to be grafted from elsewhere. Both the volume and density of the both together determine the structural quality of the bone. Patients looking for implant dentures are often deficient in bone in many parts of their jaw. Exactly which places sufficient bone is available affects the planned location and the number of implants. In the case of the upper jaw, the number also depends on how many teeth you want to have there, and how many natural teeth are present on the lower jaw.

The decision as to how many implants are optimally required will be taken after a thorough examination. This examination can include a panoramic or a cone-beam x-ray, along with bone density tests. These tests will decide how many implants, and what type and size of implants are required. Their positions and angular orientation will also be carefully determined for optimal strength at minimal cost. The number of implants employed to support a denture could also be affected by your budget priorities.
