Arms Assigned Interventions
Experimental: lingualized
complete denture fabricated by lingualized occlusion scheme
Procedure: lingualized occlusion
occlusal surface arranged by lingualized occlusion
Other Name: e-ha artificial teeth, shofu porcelain teeth
Placebo Comparator: Full Bilaterally Balanced Articulation
complete denture fabricated by Full Bilaterally Balanced Articulation scheme
Procedure: Full Bilaterally Balanced Articulation
occlusal surface arranged by Full Bilaterally Balanced Articulation
Other Name: Shofu Ace Posterior

Detailed Description:
Two occlusal scheme applied to complete denture prosthodontics has been compared in RCT. This will have clinical benefit for deciding which occlusal scheme is better according to patient conditions. It will also have impact on dental educational curriculum.
