Details and patient eligibility

About

It is a randomized controlled trial to evaluate two surgical techniques for dental implant placement simultaneously with bone augmentation.

Full description

Implants receiving Contour Augmentations at the time of placement are randomized into two groups, submerged and non submerged. Healing is evaluated at 4 months post op compared to the day of surgery.

Enrollment: 28 patients

Sex: All

Ages: 21+ years old

Volunteers: Accepts Healthy Volunteers
