LLUSD (2015) - Chapter 27 - Peri-Implants Tissue Evaluation and Post-Prostodontic Care of Implants Approximately 1.5 millimeters of marginal bone is lost around implants during the first year after placing the prosthesis.*TrueFalseAt each recall visit, the probing depth around implants should be checked by using a regular metal periodontal probe.*TrueFalseConventional metal instruments and ultra-sonic scalers can be used around implants for oral prophylaxis.*TrueFalseThe peri-implant mucosa seems less effective than gingiva in encapsulating plaque-associated lesions.*TrueFalseThe soft tissues around implants normally have the same color and consistency as healthy gingiva.*TrueFalseThe probing depth around implants is greater than around teeth.*TrueFalseThe junctional epithelium around implants normally has a length of 1 millimeter.*TrueFalseDuring the first year of treatment following surgery and prosthesis insertion, the patient should be seen every 6 months.*TrueFalseThere is no difference in the vascular topography when comparing the periodontium to the peri-implant tissue.*TrueFalseWhen patients refrain from oral hygiene around implants, the accumulation of plaque leads to the development of peri-implant mucositis via a similar cause-effect relationship to that of gingivitis around teeth resulting from plaque.*TrueFalse
