Abstract
At the Harvard Meeting of 1978 the recommendation was obtained,“Only two kinds, Mandibular Subperiosteal Implant and Blade Vent Implant will be permissible provided they will be practiced based on adequate technology learned and judgment of good common sense and ethics of thought introduced”. However, there are many issues involved by Subperiosteal Implant as well. One of such issues will be the problem of initial fixation. In many cases Subperiosteal Implanting will be applied to Complete Edentulous cases and Multiple Teeth Deficiency cases which will difficult to cure throgh other methods of treatment. For that reason undercut will be less and no initial fixation of frames can be achieved. To cope with the situation there are various kinds of initial fixation countermeasures are reported. Hence, the author has classified and studied such countermeasures.
1. The method to use metallic screws
2. Combination use of Intraosseous Implanting to design stabilization.
3. Method for fixation in which remaining teeth will be utilized to connect frames.
4. Inner bone system.
5. Endosseous Subperiosteal Implant.
6. Method in which the bone undercut will be utilized.
