Brief Summary
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.

Conditions
Outcome Measures
Primary Outcomes (2)
Buccolingual ridge width
Buccolingual ridge width will be measured through a stent via ridge mapping calipers. The measurement locations will be at 1mm, 3mm and 5mm from the midbuccal crest. The same measurements will be recorded at all selected time points.
(1) After local anesthesia and before extraction, (2) immediately after extraction and (3) 4 months after extraction and alveolar ridge preservation
Ridge height
Ridge height will be measured through a stent via a periodontal probe as the distance between bone and predetermined landmarks on the stent. The measurement locations will be mesial buccal, midbuccal, distal buccal, mesial lingual, midlingual and distal lingual. The same measurements will be recorded at all selected time points.
(1) After local anesthesia and before extraction, (2) immediately after extraction and (3) 4 months after extraction and alveolar ridge preservation
Study Arms (4)
Non-molar sites with immediate post-extraction ridge expansion
Non-molar sites with an increase of buccolingual bone width immediately after tooth extraction compared to pre-extraction.
Non-molar sites with no immediate post-extraction ridge width change
Non-molar sites without a change in buccolingual bone width immediately after tooth extraction compared to pre-extraction.
Molar sites with immediate post-extraction ridge expansion
Molar sites with an increase of buccolingual bone width immediately after tooth extraction compared to pre-extraction.
Molar sites with no immediate post-extraction ridge width change
Molar sites without a change in buccolingual bone width immediately after tooth extraction compared to pre-extraction.
Interventions
Observational study; alveolar ridge preservation
Eligibility Criteria
Patients scheduled for tooth extraction and alveolar ridge preservation (bone graft and membrane) in the Graduate Periodontics Clinic at Marquette University School of Dentistry.
You may qualify if:
- 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
You may not qualify if:
- 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.
