Summary

Evaluating the bone changing after receiving one-piece implants supported full arch prosthesis compared to the conventional two-piece implants.

Conditions

  • Marginal Bone Loss
  • One-piece Implants Versus Two-piece Implants During the Osseointegration Phase

Interventions

DEVICE

One-piece dental implants with MUA

one-piece dental implants with multi-units abutment mounted on the implants as a single piece provided with different abutment angulation utilizing these implants for All-On-Four prothesis

DEVICE

Two-piece dental implants

Surgical and immediate loading procedures: On the day of implant placement, patients will receive two-piece implant. After crestal incision and full-thickness flap elevation, the implant sites will be prepared aided by a surgical template. 4 implants will be placed, two aligned in an axial orientation and two will be distally aligned (17 degrees). The standard placement procedure as recommended by the manufacturer will be used. The surgical drills with increasing diameters will be used to prepare the implant sites. Implants will be ideally placed at bone level (or 1 mm deeper depending on the soft tissue thickness). After 3 months as a healing phase, a definitive prosthesis will be fabricated using the same abutments, and the marginal bone loss after the osseointegration phase will be assessed.
