Dimensional Soft and Hard Tissue Alterations Following Single Tooth Extraction in the Anterior Maxilla - A Prospective Clinical Study

NCT02403700 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 39

No results posted yet for this study

Summary

Bone modeling after tooth extraction has a major consequence on implant therapy, in particular in the esthetic zone. In esthetic sites, no tissue loss should occur if an optimal esthetic outcome is expected. Recent experimental studies in dogs have shown that neither an immediate implant insertion nor ridge preservation techniques can prevent this bone modeling process.

Conditions

  • Dimensional Alterations

Interventions

DEVICE

Cone beam computed tomography (CBCT)

Dimensional changes are documented over a healing period of 8-weeks following single tooth extraction. To document these changes over time, two methods will be applied. Firstly, two cone beam computed tomographies (CBCT) will be obtained, one directly after tooth extraction, the other one at 8 weeks of socket healing prior to implant placement. The two CBCT's will be analyzed with a novel software program (InVivo Dental). Secondly, consecutive impressions will be made at day 0 (day of extraction), day 14, 28, 42, and 56 to digitally produce virtual 3D study models. These models can be analyzed with another software program (Geomagic Studi 10) to document the variations of the soft tissue in the extraction site.
