A Post Market Clinical Follow-up Study on Biomet Microfixation HTR PEKK (Midface), Facial & Mandibular Plates.

Completed

• Conditions: Facial Fracture; Hemifacial Microsomia; Treacher Collins Syndrome; Mandibular Fractures; Neuroma; Cleft Face; Miller Syndrome; Tumor; Fibrous Dysplasia; Osteoma of Mandibular Condyle
• Interventions: Device: HTR-PEKK; Device: Titanium Facial Plates; Device: Titanium Mandibular Plates; Device: Add-on Condyle

• Registration Number: NCT04931056
• Lead Sponsor: Zimmer Biomet

Brief Summary

This study will address medical devices manufactured by Biomet Microfixation (d.b.a. Zimmer Biomet) designed for fixation and stabilization of the facial and mandibular skeleton.

Detailed Description

The subject devices are:

* plates, screws, and primary instruments from the Biomet Microfixation Facial Plating System, including plates to be specifically used in orthognathic procedures

* plates, screws and primary instruments for the Mandibular Plating System, including and a device intended to temporarily restore the functionality of the temporomandibular joint for patients whose natural condyle has to be resected, subsequent to a tumor ablation ("Add-On Condyle") Additionally, a third device intended for the replacement of bony voids in the facial skeleton will be evaluated in this trial (HTR-PEKK- facial application).
