Hello

I was just wondering if all implants require the gum to be cut open again (to expose the sealing cap and fit the new crown) after the 3 month bone healing process or do some implants negate the need for this? If so, which makes of implants do not require the gum to be reopened?

Moreover, on the same subject, if some implants do not require the gum to be reopened, how does the new crown sit under the gumline (as opposed to on top of it) if the gum has healed?

Many thanks
