The Use of Intraoral Imaging at Clinical Crown Lengthening Procedures
Crown lengthening surgery is done when a tooth needs to be fixed with a crown. Sometimes, not
enough of the tooth sticks out above the gum to support a crown. This can happen when a tooth
breaks off at the gum line, or when a crown or filling falls out of a tooth and there is
decay underneath. To place a crown, the dentist needs to expose more of the tooth. This is
done by removing some gum tissue or bone.
After surgery, the area will heal in about three months. Then, making a crown can begin. This
healing period often delays the delivery a final crown. This study is investing a way to make
the final impression at the surgery to expedite the delivery of a final crown.

The purpose of this prospective study is to evaluate clinical and radiographic outcomes of
single unsplinted fixed restorations made with digital intraoral imaging in conjunction with
clinical crown lengthening procedures (CLPs) compared ones fabricated by the conventional
protocol.
Specific Aim 1: To evaluate the clinical outcomes between the experimental group (the digital
impression taking at clinical crown lengthening procedures) and the control group (the
conventional protocol) Hypothesis: There will be no differences in clinical parameters around
the teeth between the two groups.
Approach: The investigators will conduct a prospective clinical study and will compare the
changes in gingival recession, the width of keratinized gingiva, and pocket depths around the
teeth between the two groups.
Specific Aim 2: To evaluate the radiographic outcome between the experimental group and the
control group Hypothesis: There will be no difference in crestal bone level around teeth
between the two groups.
Approach: The study will investigate the difference in crestal bone level around the teeth at
baseline and 12 months between the two groups.
