Study Evaluating the Performance and Safety of Global D Implants Indicated for Orthognathic Surgery (CMF-ORTHO)

January 13, 2026 updated by: Global D

Prospective Study to Evaluate the Performance (by the Assessment of Patient's Quality of Life) and the Safety of Global D's Implants of Cranio-maxillofacial Surgery Indicated for Orthognathic Surgery

This study is set up within the framework of the European Union regulation 2017/745 on medical devices. Its objective is to confirm the performance and safety of the Global D implants (ORTRAUTEK® and MINITEK®) used for orthognathic surgery.

Sampling Method

Non-Probability Sample

Study Population

The study population is composed of male and female, major or minor, who will be treated by orthognatic surgery (maxillary, mandibular, maxillomandibular or/with genioplasty). The bone maturity of the participants (assessed by investigators) need to be sufficient for the treatment.

Description

Inclusion Criteria:

  • Male or female patient, major or minor, having reached bone maturity according to the judgement of the investigator,
  • Patient having first orthognathic surgery (maxillary, mandibular, maxillomandibular or/with genioplasty)
  • Patient who received orthodontic treatment prior to orthognathic surgery.
  • Patient with abilities to read, understand and answer to the study quality of life questionnaire.
  • Patient (and his legal representative if minor) who signed the study consent form.
  • Patient affiliated to a social security system.

Exclusion Criteria:

  • Patient allergic to one of the components of the implants
  • Patient with physical or mental inabilities that will compromise the follow-up during the study
  • Patient with acute or chronic infection (local or systemic)
  • Person on legal protection
  • Pregnant or breastfeeding women

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Study group
Male and female, major or minor, who will be treated by orthognathic surgery (maxillary, mandibular, maxillomandibular or/with genioplasty). The bone maturity of the participants (assessed by investigators) need to be sufficient for the treatment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Performance of the Global D's implants used for orthognathic surgery, assessed by the Orthognathic Quality of Life Questionnaire (OQLQ) before and after the surgery.
Time Frame: 1 year
The evolution of patient's quality of life will be assessed by comparing the score of the Orthognathic Quality of Life Questionnaire (OQLQ) before and after the surgery. The OQLQ can vary from 0 (better quality of life) to 88 (worst quality of life).
1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Security of the Global D implants used for orthognathic surgery - Outcome Measure 1a
Time Frame: 6 weeks after the surgery
Bone consolidation after the surgery, assessed by a correct dental occlusion on the postoperative image. This information is assessed 6 weeks after the surgery: correct occlusion (Yes/No).
6 weeks after the surgery
Security of the Global D implants used for orthognathic surgery - Outcome Measure 1b
Time Frame: 6 weeks after the surgery
Bone consolidation after the surgery, assessed by the alimentation of the patient. This information is assessed 6 weeks after the surgery: solid alimentation of the patient (Yes/No).
6 weeks after the surgery
Security of the Global D implants used for orthognathic surgery - Outcome Measure 2
Time Frame: 18 months
Adverse events identification, assessment and follow-up.
18 months
Surgeon satisfaction on the implant's utilisation
Time Frame: Immediately following surgery
Assessment by a satisfaction questionnaire, specially developed for the study, completed by the surgeon after the surgery. The surgeon evaluates each item using a likert scale (Highly Satisfied/ Satisfied/ Not very satisfied / Unsatisfied).
Immediately following surgery
