Summary

For this study, twenty patients were selected, and participants were randomly divided into two groups using random numbers produced in an Excel spreadsheet. Each patient got four implants in the mandibular canine and first molar sites, as well as the bar attachment. The purpose of this study was to document and report patient satisfaction with mandibular implant overdentures with quadrilateral distribution and linear distribution. The null hypothesis was that patient satisfaction would not be different depending on the distribution type (quadrilateral or linear). According to the bar design, all patients were classified into two equal groups: quadrilateral bar design (group I) and bilateral linear bar design (group II). Peri-implant marginal bone loss was evaluated immediately (T0) and after 2 years (T2) of overdenture insertion using a digital periapical X-ray.

Conditions

• Edentulism

Interventions

Type	Name	Description
OTHER	Implant	A long cone paralleling approach with a specially made film holder will be used to assess each patient's vertical marginal bone loss to ensure standardized radiography analysis and avoid any magnification errors. The linear distance between the proximal crestal bone level and the implant shoulder will be measured at the mesial and distal aspects of the implant measured in millimeters (mm). Measurements will performed using image measurement software patient satisfaction comparison between 2 groups
