Single tooth deficiencies: With the classical system, a single tooth deficiency can be eliminated by abrading two adjacent teeth in a comic shape and producing a 3-member bridge reinforced by them. In this case, a more aesthetic and functional treatment can be achieved with a single implant, without touching the adjacent teeth. Completely toothless condition (total toothlessness): The total prosthesis (palate) applied in case of total toothlessness is the type of prosthesis with the weakest retention in the mouth. The fact that it moves to various degrees during chewing and speaking negatively affects patient comfort. In patients with sufficient bone levels, at least 5-6 implants are applied to each jaw and a fixed prosthesis is made on top of them. Secondly, in cases where bone levels are not suitable, implants are applied to the anterior region and a removable prosthesis is made based on these implants. The aim of this option is to increase the retention of the removable prosthesis and make it easier for the patient to use it. Jaws with toothless back ends: This makes bridge production impossible. In order to make a bridge for missing teeth, the patient must have his own tooth at the end and end of the missing part. For this reason, a removable prosthesis (half palate) is applied to toothless jaws. In patients who refuse to use removable dentures, fixed dentures can be made by applying implants to toothless areas. In cases of long edentulism: Even if the patient has natural teeth at the beginning and end of the edentulous area, a bridge cannot be applied because it will be too long. Because there is a danger of breaking and stretching on long bridges. In addition, the lifespan of the teeth to be used as bridge pillars will be shortened as they will be overloaded. In such cases, a more functional and long-lasting prosthesis is made by applying an implant to the long gap.
