Primary Outcome Measures

Name	Time	Method
Bacterial plaque indicator	6 months	the amount of plaque on the gingival edge on the tooth surface is determined by using a probe. This indicator does not need to color the plaque. This indicator is taken for all teeth monthly over a period of 6 months
Patient Acceptance Assessment:	6 months	Patient acceptance will be evaluated according to a set of questions presented in a questionnaire sheet for each patient in the hospital; Each period of the review where patient acceptance was recorded in three aspects: 1. Speech: The extent of the effect of the affixed fixative on the patient's comfort with speech will be recorded in each follow-up period in the event that there is no difficulty in speaking or there is difficulty in speaking.; Is there a proven effect on speech? )Yes No(; 2.
