简要总结

Is patient specific customized computer assisted 3D PEEK plates more superior to 3D titanium plate in fixation of mandibular angle fractures?

详细描述

Open Reduction Internal fixation (ORIF) of mandibular angle fractures using titanium plating systems had several drawbacks including sepsis with subsequent wound dehiscence and the need for 2nd surgery which is attributed to bone loss as a result of the elevated modulus of elasticity of titanium hardware. Accordingly, attempts were made to overcome problems encountered with the titanium plating system. In this study, custom made PEEK 3D plates will be used in ORIF of mandibular angle fractures. The main beneficial property of PEEK material is its lower modulus of elasticity that is close to that of living bone with subsequent elimination of the problem of stress shielding phenomenon encountered with titanium plating system. PEEK material has other advantages including biocompatibility, mechanical strength, durability, resistance to high degree of temperature without dimensional alteration.

研究组 & 干预措施

Computer-assisted PEEK custom made 3D plates

Experimental

Patients were treated using computer-assisted patient-specific PEEK plates manufactured by CAD/CAM technology and fixed using titanium screws.

干预措施: Patient-specific PEEK plates manufactured using CAD/CAM technology and fixed using titanium screws. (Device)

3D titanium plates on the mandibular angle will be fixed using titanium screws

Active Comparator

Patients were treated using conventional 3D titanium plates fixed with titanium screws after reduction of the fracture.

干预措施: Conventional 3D titanium plates (Device)

结局指标

主要结局

Postoperative occlusion stability(binary: yes/no)

时间窗: 1 week, 1 month, and 6 months postoperatively

Occlusal stability was recorded as stable or unstable. Occlusal stability was assessed clinically by evaluating the intercuspation between maxillary and mandibular teeth. Proper occlusion was defined as normal intercuspation without premature contacts or occlusal discrepancies. Any deviation, including open bite or malocclusion, was recorded during follow-up.

次要结局

  • Condylar seating (binary: yes/no)(1 week, 1 month, and 6 months postoperatively)
  • Postoperative infection (binary: yes/no)(1 week, 1 month, and 6 months postoperatively)
  • Wound dehiscence (binary: yes/no)(1 week, 1 month, and 6 months postoperatively)
  • Need for second surgical intervention ( binary: yes/no)(1 week, 1 month, and 6 months postoperatively)
