No results posted yet for this study

Summary

Tooth extraction is followed by marked alterations of the tissue volume. The resorption process of at least the surrounding mucosa can be altered by using immediate implant placement and additional features such as immediate provisional crown, platform switching and grafting the gap between implant and buccal bone plate. The support of the gingival margin with a provisional crown led to an increase of buccal gingival tissue.

Teeth scheduled for extraction will be used to study the effect of a customized healing abutment.

The following groups will be randomly assigned:

Control: A commercially available healing abutment will be screwed on top of the implant and a collagen sponge will be used to protect the graft.

Test: A customized PEEK abutment mimicking the subgingival emergence of the extracted tooth will be screw retained on top of the implant to seal the extraction site.

Conditions

  • Edentulous Alveolar Ridge Atrophy

Interventions

DEVICE

Immediate post-extractive Implant placement

Teeth scheduled for extraction will be used to study the effect of a customized healing abutment. All patients should receive prophylactic antibiotic therapy of 2g of amoxicillin (or clindamycin 600mg if allergic to penicillin) 1 hour before the surgery. Implant placed along the lingual/palatal bone plate and the implant platform should be placed at the level of the buccal bone plate. GUIDOR easy-graft CRYSTAL will be used to fill the defect between implant and buccal bone plate, subsequently, a standard healing abutment or a customized healing abutment will be screw-retained on the implants.
