Determinants of Bone Dimensional Changes After Extraction and Alveolar Ridge Preservation

Who can join

Ages 18 to 75 · All sexes · Healthy volunteers welcome

Inclusion Criteria:

* Adult patients (18-75 years)
* Good general health (controlled conditions)
* Controlled periodontal disease
* Scheduled for single tooth extraction with bone graft placement and resorbable membrane
* Tooth to be extracted must have adjacent teeth
* Socket wall integrity

Exclusion Criteria:

* Smoking
* Pregnancy
* Active periodontal disease
* Systemic conditions that affect healing
* Lack of socket wall integrity (bone loss ≥50 %) prior to extraction, teeth with severe infection requiring pre-extraction antibiotic treatment to control infection), and contraindications for tooth extraction.

About the study

The main purpose of the study is to measure and localize immediate post extraction changes i.e. socket expansion versus no width change along the socket wall and identify whether the immediate post-extraction ridge width condition (expansion or no change) is a determinant of buccolingual ridge width and height changes 4 months following extraction and ridge preservation.
