NCT06219811

Brief Summary

The goal of this randomized clinical trial is to compare and assess the prosthetic maintenance of two implant-retained mandibular overdentures reinforced with PEKK and Co-Cr frameworks after twelve months. Twenty-four participants were randomly assigned to two groups: Group I received a mandibular implant-retained overdenture reinforced with a Co-Cr framework, while Group II received a mandibular implant-retained overdenture reinforced with a PEKK framework. Also, both groups were rehabilitated with a maxillary complete removable denture.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of Prosthetic Maintenance of both types of implant retained overdentures

    Evaluation of prosthetic maintenance for mandibular implant-retained overdentures in both groups was made after twelve months of overdenture insertion. Prosthetic maintenance is a checklist for the following aspects that were inspected regarding screw (screw loosening, screw fracture), attachments (wear, distortion, fracture, replacement), and overdentures (reline, remake, fracture, teeth wear, teeth separation, or fracture).maintenance for complication assed through counting frequency of incidence. The unit of measurement used is percentage.

    twelve months after delivery of implant retained overdenture

Study Arms (2)

Mandibular implant-retained overdenture reinforced with a Co-Cr framework

EXPERIMENTAL

The patient received a mandibular implant-retained acrylic overdenture reinforced with a Co-Cr framework. The framework is manufactured by milling polymethylmethacrylate (PMMA) and then the PMMA undergo conventional casting to produce cobalt chromium (Co-Cr) framework. The framework included in the overdenture by conventional processing technique.

Device: Two implant -retained overdenture reinforced with Co-Cr framework

Mandibular implant-retained overdenture reinforced with a PEKK framework

ACTIVE COMPARATOR

The patient received a mandibular implant-retained acrylic overdenture reinforced with a Polyetherketoneketone (PEKK) framework. The framework is manufactured by milling PEKK the framework included in the overdenture by conventional processing technique.

Device: Two implant -retained overdenture reinforced with PEEK framework

Interventions

The intervention is made from polymethylmethacrylate reinforced with cobalt chromium ( Co-Cr) framework.

You may qualify if:

  • Age range between 50-70 years old.
  • Completely edentulous patients
  • Systemically free from any disease that contraindicates implant placement.
  • A minimum of 12 -15 millimeters of bone height and 6 mm bone width at canine areas diagnosed from the pre-operative cone beam CT.
