Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The null hypothesis for this study is that there is no difference in bone ridge width and height changes 4 months following extraction and alveolar ridge preservation at sites that undergo immediate post-extraction socket expansion or no immediate post-extraction ridge width change. Patients of the Graduate Periodontics Clinic at Marquette University School of Dentistry scheduled for extraction, bone graft and resorbable membrane will be recruited for this study.

After providing informed consent and prior to local anesthesia and extraction, the following parameters will be recorded: age, gender, race, medical history, medications, tooth site, reason for extraction and tooth mobility. Gingival width will be recorded prior to local anesthesia and extraction, and at 4 months. Gingival thickness will be recorded after local anesthesia and prior to extraction, and at 4 months. Buccolingual ridge width and ridge height will be recorded immediately before, immediately after extraction, and at 4 months. Immediately after extraction, the following measurements will be recorded: buccal bone thickness, number of roots, root length and width, instruments used for extraction, need for flap elevation, duration of extraction, anesthetic amount, type and approach, and operator experience.
