In the previous post, a group of instruments for bone expansion was analyzed.

Bone atrophies must be treated adequately to allow the implant placement in optimal position, according to the biomechanical requirements, and also to achieve better esthetics of the future crowns.

Here we are presenting a case, where there is bone atrophy and a low insertion of the frenulum. 

The therapeutic approach was to make a bone expansion together with a frenectomy.

Bone atrophy and a low insertion of the frenulum.

After raising the flap, the bone atrophy is

observed, which is more important in the

anterior part.

Expander number 3 in position.

Expander number 4 in position. With this one

is enough to place a 4 mm diameter implant.

In the buccal aspect the suture associated

with the frenectomy is observed.
