Guidelines for implant selection after maxillofacial trauma

Guidelines for implant selection after maxillofacial trauma

Maxillofacial Trauma Overview

Definition:
Maxillofacial trauma refers to injuries caused by external forces to the facial skeleton and soft tissues, 

involving 14 interconnected osseous structures, including the maxilla, mandible, zygomatic bone, and orbit.

Unique Clinical Characteristics:

Functional Convergence Zone:
Concentrates vital functions such as respiration, mastication, phonation, and sensory perception.

Aesthetic Critical Zone:
Facial contour morphology directly impacts psychosocial well-being and quality of life.

Anatomical Complexity:
Contains 3–5 neurovascular bundles per cubic centimeter

I.Assessment of the type of trauma and goals of repair

1. Fracture complexity

1.1 Simple linear fractures:

Absorbable material (e.g. PLLA) or pure titanium microplates

1.2 Comminuted/weight-bearing zone fractures:

Titanium (Ti-6Al-4V) reconstruction plate

1.3 Paediatric fractures:

Prefer PEEK material (to avoid bone growth inhibition)

2. Functional and aesthetic requirements  

2.1 Restoration of occlusal function:

Choose titanium alloy with high fatigue strength (≥900MPa)

2.2 Facial contour reconstruction:

3D preformed titanium plate or intraoperative navigation adaptation system Translation into English

II. Core Consideration Dimensions of Material Selection
