Details and patient eligibility

About

The objective of this clinical trial is to evaluate crestal bone loss every three months at time of overdenture insertion, 3, 6, 9, 12 months from overdenture use. Also, to evaluate prosthesis satisfaction.

All participants will receive conventional complete dentures, followed by two intraforaminal implants. After healing time, fabrication of secondary copings in all cases according to randomized groups for final overdenture insertion.

Enrollment: 30 patients

Sex: All

Ages: 55 to 75 years old
