Clinical and Radiographic Outcomes of Alveolar Ridge Preservation

Condition(s) studied

Study summary

Dental implants are considered a predictable rehabilitative option following tooth extraction or in cases of missing teeth. In some situations, the inevitable alveolar ridge resorption that occurs after extraction may make the placement of standard-diameter (\>3.5 mm) or standard-length implants difficult or even impossible without advanced bone augmentation procedures. To counteract post-extraction volumetric bone contraction, alveolar ridge preservation can be performed, consisting of placing a bone graft within the socket walls immediately after tooth extraction. Although this procedure cannot completely prevent dimensional changes, it has been shown to significantly reduce both horizontal and vertical ridge resorption, as reported in the scientific literature. However, there is a lack of clinical and radiographic studies evaluating the outcomes of implant rehabilitation following alveolar ridge preservation with standard-dimension implants in a hospital-based setting.

Eligibility

Primary outcome measure(s)

• Volumetric analysis — From tooth extraction to 6 months of follow up.
  The dimensional change of hard tissues following bone regenerative procedures will be assessed radiographically by measuring horizontal and vertical bone resorption through CBCT comparison in patients treated in a hospital-based setting.
