Personalized Titanium Plates vs CAD/CAM Surgical Splints in Maxillary Repositioning of Orthognathic Surgery

2016-09-26 22:23:21 | BioPortfolio

Summary

The purpose of this study is to determine whether personalized titanium plates can achieve better accuracy than CAD/CAM surgical splint in maxilla repositioning in orthognathic surgery, and evaluate the feasibility of this technique in clinical application.

Description

The repositioning of maxillary segment is essential for esthetic and functional outcomes in orthognathic surgery. With the giant leap in three-dimensional (3D) computer-aided surgical simulation (CASS) technology development, surgeons are now able to simulate various surgical plans in a computer to achieve the best possible outcome. In order to transfer the virtual surgical plan to the patient at the time of the surgery, surgical splints manufactured by computer-aided design and manufacturing (CAD/CAM) technique has been traditionally used to intraoperative reposition the maxilla. Nonetheless, the position of maxilla is still dependent to mandibular autorotation. The instability of the mandibular condyle-fossa relationship is a potential problem that may directly affect the placement of the maxillary segment at the desired position. Personalized titanium plates manufactured using titanium 3D printing technique have been used for maxilla repositioning and fixation to improve the operative accuracy in orthognathic surgery. Despite this, the evidence for advantage of this personalized titanium plates technique is not very strong and based on only a few studies.

The purpose of this study is to determine whether personalized titanium plates can achieve better accuracy than CAD/CAM surgical splint in maxilla repositioning in orthognathic surgery. The accuracy of using both methods for maxilla repositioning was quantitatively evaluated using linear and angular measurement. Secondary outcomes include operative time, amount of intraoperative blood loss, preoperative preparation time and treatment cost will also be measured to evaluate the feasibility of clinical application of personalized titanium plates technique in orthognathic surgery.

Medical and Biotech [MESH] Definitions

Malocclusion in which the mandible is anterior to the maxilla as reflected by the first relationship of the first permanent molar (mesioclusion).

Malocclusion in which the mandible is posterior to the maxilla as reflected by the relationship of the first permanent molar (distoclusion).

The region in the dorsal ECTODERM of a chordate embryo that gives rise to the future CENTRAL NERVOUS SYSTEM. Tissue in the neural plate is called the neuroectoderm, often used as a synonym of neural plate.

Malocclusion in which the mandible and maxilla are anteroposteriorly normal as reflected by the relationship of the first permanent molar (i.e., in neutroclusion), but in which individual teeth are abnormally related to each other.

The head of a long bone that is separated from the shaft by the epiphyseal plate until bone growth stops. At that time, the plate disappears and the head and shaft are united.
