Crestal Bone Loss in Mandibular Telescopic Overdentures. Overdenture with Milled Titanium, Milled Poly-ether Ketone Ketones and 3D Printed Chrome Cobalt Secondary Copings.

Crestal Bone Loss in Mandibular Telescopic Implant Retained Overdenture with Milled Titanium, Milled Poly-ether Ketone Ketones and 3D Printed Chrome Cobalt Secondary Copings

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.

Inclusion Criteria:

1. Sufficient remaining bone in height, width and thickness in the interforaminal area to allow installation of at least 3.3 mm diameter and 8 mm length implants.
2. Adequate amount of interarch space of at least 12mm.
3. Age range from 55 to 75 years old age.

Exclusion Criteria:

1. Systemic and metabolic diseases that may affect osseointegration.
