Although operations of implant in dentistry are expensive, operations are increasing every year. However, when operations failed, then it would rise to serious side effects such as malocclusion, falling off, fracture, infection and others. The model(A Type Bridge, B Type Bridge, Fitness Bridge) of the set of fixture and alveolus are made by using a CAE software. Finally, we have obtained a combination bridge solution by using orthogonal array.
