3.2a Clinical concept in the non-aesthetic region
Remark: The non-aesthetic region is considered the lateral-posterior area.
Background information
Dr. Tiziano Testori and Dr. Matteo Capelli:
“Immediate post-extraction implants represent a valid approach for optimizing
the surgical procedures, the timing and the management of the aesthetic issues
after tooth extraction in the anterior area.
Implants were thought to preserve bony buccal plates from resorption. However,
recent studies1,2 and our clinical experience underline that buccal bone resorption takes place despite the placement of an implant immediately after tooth
removal. Bone augmentation procedures are often required at the time of
implantation since the goal is to preserve the buccal plate and to reduce bone
resorption over time. Furthermore, an aesthetic score is needed to evaluate the
outcome3.”
Case A Implant bone distance > 3 mm
Case B Implant bone distance < 3 mm

Fig. 11a Occlusal view of the healed site.
Limited bone resorption can be noted buccally.

There is a slight mucosal screw exposure at
the level of the implant.

Fig. 9b Placement of a Bio-Gide® membrane
in a double layer and a pedicled palatal
graft is used in addition to cover the membrane. To obtain a better soft tissue profile
on the palatal side, the thick tissue has been
split and rotated towards the vestibule.

abutments. Note the graft stability after 6
months of healing.

implantation: Implant positioned with
healing abutment. Note the mesio-distal
intra-gap bone graft.

the bone graft around the post extraction
implant.
2. Aims of the therapy
> Maintenance of buccal and palatal bone volume after tooth extraction by placing
Bio-Oss® granules into the residual gap and overbuilding the buccal wall by 20%.
3. Surgical procedure
3.1 Clinical problem: Considerable bone resorption after tooth extraction

6 months. Note the considerable buccal
bone resorption.

crown delivery 6 months after implantation.
