Hypothyroidism: Implications for Implant Placement?

Dr. C. asks:
I have treatment planned a patient for multiple extractions and immediate insertion of 4-mini-implants in the mandibular symphysis area with immediate insertion of a mandibular overdenture. I will reline the overdenture with soft reline material and engage the undercuts on the mini-implants. I want my patient’s physician to insure that her hypothyroidism is stable. She has been taking synthroid for 5 years with no problems. She refuses to make an appointment with her physician because she says that synthroid is the fourth most common drug in the U. S. and so many people take the drug without complications that she does not understand why she needs a separate medical consult. Should I insist that she have this medical consult or should I just consider her stable enough for treatment?
