The lower right first molar was extracted due to severe periodontitis resulting in loss of bone support. Two mini dental implants were immediately inserted into whatever bone was available. The patient was covered with antibiotics for several days. A porcelain bonded to metal crown was fixed about 2 months later over a composite core that was lightcured over the minis. Six years later, an xray was taken.... looks like the bone has "climbed up" the implant. The tooth was firm and functional.

This case report provides
clinical and histologic proof that the immediate placement of implants into
extraction sockets with an intact buccal wall allows healing and osseointegration
despite a large gap distance and without primary flap closure, a bone graft, or
a barrier membrane. (Int J Periodontics Restorative Dent 2011;31:515–521.)
In the discussion, the following statement was made:-
It is possible then that an
implant placed in an extraction site
without soft tissue closure could
heal with bone-to-implant contact
before the soft tissues have an opportunity
to interfere.
However, I beg to differ.
Based on the case shared on "Bone Climbing Up Mini Dental Implant",
my postulation is as follows:-
In spite of the absence of a buccal and lingual plate, no well defined socket,
a mini dental screwed into the cortical plate at the bottom of the bony crater
left behind by a mobile, periodontally compromised tooth,
will stimulate the alveolar bone to reform and grow around the implant
to a more normal level
in spite of the presence of granulation and epithelial tissue.
