RESTIT : Evaluation of Resorbable Osteosynthesis Devices Versus Titanium in Maxillofacial Surgery

RESTIT : Evaluation of Resorbable Osteosynthesis Devices Versus Titanium in Maxillofacial Surgery - A Prospective Randomized Trial in Therapeutic Strategy

Primary objective : To evaluate the quality of fractures setting and osteotomy of the facial massif osteosynthesised with resorbable device PLLA/PGA compared with usual Titanium plates.

Secondary objective :

• To evaluate the resorbable device ergonomy versus Titanium.
• To evaluate the clinical tolerance of resorbable device versus Titanium.

Hypothesis :

Osteosynthesis with resorbable device demonstrates a non inferiority success probability regarding the success observed in osteosynthesis with Titanium, with a less important probability of re-operation.

Study duration : 14 months for each patient.

Study treatment :

• Group I : Resorbable device PLLA/PGA.
• Group II : Titanium device.

Study visits :

- Screening visit - Baseline with randomization and surgery - Day1 - Day 21 - Day 45(Traumatology)/Day 90 (orthognatic) - Month 6,12 and 14.

Randomization : Stratification by centres, mono or bimaxillar surgery and traumatologic or orthognatic criteria.

• Signed informed consent.

Exclusion Criteria:

• Any previous surgery at the same operative site.
