Condition(s) studied

Alveolar Bone Loss

Investigational drug(s) / intervention(s)

BARPsimple tooth extractiontooth root and PRFIce cream cone technique

BARP: deep layers of collagen, medium-superficial heterologous bone graft, superficial collagen layer

simple tooth extraction: tooth extraction without grafting procedure.

tooth root and PRF: Autogenous roots derived from the extracted hopeless tooth and stabilized with osteosynthesis screws to reconstruct the missing buccal wall of the socket. The defect was then filled with PRF.

Ice cream cone technique: xenogeneic granules and a resorbable collagen membrane

Study summary

Post-extractive alveolar ridge remodeling represents a physiological phenomenon that may hamper successive implant insertion. Several techniques have been proposed without any significant difference of efficacy among them. Moreover several research protocols of analysis have been proposed, including histomorphometric, radiological, clinical analysis.

The purpose of the present study is to test different alveolar ridge preservation techniques using histomorphometric and optical scanning analysis.
