The role of computer‐aided 3D surgery and stereolithographic modelling for vector orientation in premaxillary and trans‐sinusoidal maxillary distraction osteogenesis

Abstract

Preoperative bending of internal maxillary distractors prevents significant loss of operation time. 3D computer-aided surgical simulation and model surgery provide accurate orientation of distraction vectors for premaxillary and internal trans-sinusoidal maxillary distraction. Combination of virtual surgical simulation and stereolithographic models surgery can be validated as an effective method of preoperative planning for complicated maxillofacial surgery cases.

Accuracy of virtual surgical planning-assisted management for maxillary hypoplasia in adult patients with cleft lip and palate

“…14 For cleft-related maxillary hypoplasia, however, there are only a few studies related to VSP. [15][16][17] To the best of our knowledge, studies evaluating the accuracy of different surgical techniques are still lacking.…”

Usos y limitaciones de la tomografía computarizada de haz cónico (TCHC) y la tomografía computarizada multidetector (TCMD) en cirugía de cabeza y cuello:

“…2018; 6 (2): 213-227 la planificación de las osteotomías y la orientación y adaptación de los distractores (intraorales y/o extraorales), labor que realiza generalmente el cirujano durante la cirugía, asumiendo retos importantes en la alineación de los distractores principalmente cuando son bilaterales en los 3 planos. El uso de este proceso facilita la elección de los distractores, facilita su colocación, disminuye los tiempos quirúrgicos y evita el daño iatrogénico de estructuras anatómicas como las raíces dentales, los gérmenes dentales, los paquetes neurovasculares y la activación de fuerzas en vectores diferentes, los cuales pueden afectar los procesos condilares y la dirección del movimiento de los maxilares (49).…”

Surgical Engineering in Cranio‐Maxillofacial Surgery: A Literature Review

“…Table 3. Different techniques of RP modeling for craniomaxillofacial surgery RP models afford manufacturing of surgical guides and splints [149] for transfer of preoperative planning (osteotomy lines, bone movements, facial asymmetry) to the operating theater in orthognathic surgery [150][151][152], implantology [153], and distraction osteogenesis [154][155]. In reconstructive oncological CMF surgery, 3D RP models of the fibula graft allow for choosing the best titanium plates, allow for the bending of the plates preoperatively (reducing the time spent in the operating theater [156]), and help in preoperatively planning the osteotomies and bone movements [156][157][158][159][160].…”
