I had Botox for my cheeks and chin and had dental implant a few days after. Will that have a bad effect overall?

There is no correlation between the two treatments.  The implant surgery has no reported effect on the Botox and the Botox has no reported effect on the dental implant.Best

yet there is no study publish showing correlation between botox and dental implant failure. infect study says Implant patients will benefit from pre-surgical BOTOX treatment. After implants are placed,
osseo-integration can be impeded by excessive functional forces in
patients with para-functional habits.

Typically you should not have any adverse effects with having a Botox treatment prior to an implant placement. However, it is always advised to notify any healthcare practitioner of any changes to your health history and/or surgeries or procedures you may have had recently, so that they are aware of any potential complications that may occur. Botox is injected into the musculature causing a "tightening" of muscles, where as implants are placed directly in bone. You should not have any potential adverse complications to having both procedures done closely together. If you do have any abnormal side effects or pain associated with the procedures, I would consult with your dentist.
