The microthreaded and platform switched implants could control the stress in the suitable
range. The splint would disturb the function. So it is necessary to know whether the splinted
single-unit crowns is fit for the adjacent multi-implants.
Outcome variables: Splinted single-unit crowns on one side implants and non-splinted
single-unit crowns on the other side Materials and method: 80-100 consecutive implants in at
