NCT06011031

Brief Summary

The aim of the current study is to assess the effect of two types of attachments (Locator, Novaloc) on the supporting structures both mechanically using stress strain analysis and biologically through measuring bone height using cbct.

Outcome Measures

Primary Outcomes (1)

  • bone level change around implants

    measurement of bone height mesial, distal to each implant

    Through study completion an average 1 year.

Secondary Outcomes (1)

  • patient satisfaction

    Through study completion an average 1 year.

Study Arms (2)

Novaloc attachment

EXPERIMENTAL

a newly developed device "novaloc attachment system"made of peek material and amorphous diamond like carbon.

Device: Novaloc attachment

locator attachment

ACTIVE COMPARATOR

a device with low-profile attachment used in cases of limited inter arch distance, provides excellent retention, possesses a self-aligning property and allow correction of implant divergence up to 20 degrees

Device: Locator attachment

Interventions

Each patient will be restored with 4 implants retained maxillary overdenture with the assigned attachment

Novaloc attachment

Each patient will be restored with 4 implants retained maxillary overdenture with the assigned attachment
