PEEK Bar Versus Titanium Bar Fabricated by CAD-CAM in Mandibular Hybrid Prostheses: A Comparative Study

N/ACompletedNCT06201169

Amr Azab Abd El-Fattah14 enrolled

Overview

CAD/CAM-fabricated PEEK bar exhibited greater dimensional deviation in comparison to its titanium counterpart. Nevertheless, patients with PEEK bars reported higher satisfaction levels and lower marginal bone loss when compared to those with titanium bars.

Fourteen patients with completely edentulous mandibular arch opposing natural dentition were selected and divided into two groups, seven patients in each. All patients received implant-supported hybrid prostheses with a bar fabricated by CAD/CAM milling technique. In group I (control), bar was fabricated from titanium, while in group ӀӀ, the bar was fabricated from PEEK. The evaluation of the study was done at 6 and 12 follow-up periods according to the following: 1- Experimentally by Geomagic (Geomagic, Japan) to detect any dimensional deviation of PEEK bars compared to titanium bars. 2-Clinically by questionnaire to evaluate the patient satisfaction. 3- Radiographically (digital periapical) to measure marginal bone loss around the implants.
