Abstract
The aim of this study was to explore the literature for clinical and histological
data of an unconventional treatment with implants placement in contact with dental
tissue (IPICDT) and to try to clarify its indications and surgical procedure particularities.Relevant
publications published until May 2019 on the IPICDT were thoroughly reviewed. Search
strategy was developed using a controlled vocabulary combination.Medline’s exploration
and manual research identified 397 articles; 15 of these were selected after screening.
IPICDT was indicated in three clinical situations: impacted teeth, ankylosed teeth,
or residual roots. Clinical and radiological follow-up were satisfied except for implants
placed in contact with (and not through) roots. Histological analysis revealed different
mineralized tissues formed on the implant surface: cementum on removed implants in
human and osteodentin on implants placed in contact with animal teeth dentin and pulp.
These findings were described as new concept of implants’ “Mineral integration.”According
to this study, the follow-up results of implants placed in contact with roots were
controversial. Some implants were stable and others were either removed or kept and
disinfected after root extraction because of bacterial infection. However, implants
placed through ankylosed or impacted teeth were stable. These findings suggest that
the clinicians have to be cautious when applying this unconventional approach. Further
studies are recommended to explore its long follow-up. It is also interesting to explore
this technique in cases of syndromic dental diseases with several impacted teeth (such
as cleidocranial dysplasia; or amelogenesis imperfecta).
