The restoration of dentition meant not only to fill the missing teeth and increase the efficiency of mastication, but also to maintain the integrity of dentition and the health of residual teeth, especially loosen teeth that could be reserved. Bone resorption might lead to teeth mobility and the change of occlusal pattern and proximal relationship. Also, the endurant threshold to bite force decreased. Occlusal loads within the normal range to loosen teeth would lead to broken down of periodontal tissues.
