Background: In the case of mandibular resection that leaves a large mandibular bone defect, a mandibular reconstruction is required to restore functional and postoperative aesthetic factors. Mandibular reconstruction plate installation on mandibular resection is very important but difcult to achieve maximum results. The formation of reconstruction plates can be preoperative and intraoperative. Preoperative stereolithography (medical rapid prototyping/MRP) can be used to form rapid and accurate plates (precontours). Objective: Report the use of MRP as an alternative tool to precontour mandibular reconstruction plate.Case management: Reported reconstruction of mandibular defects in one case of hemimandibulectomy and two cases of segmental resection with avascular iliac bone grafts using MRP through a computer-aided design and computer aided manufacture procedure (CAD/CAM) to establish preoperative reconstruction plates (precontour) so the surgery doesn’t take long time to reconstruct, by forming a mandibular models under normal circumstances.Result: The formation of a reconstruction plates (precontour) using MRP (medical rapid prototyping) with CAD / CAM procedure gives results in accordance with the original form.Conclusions: The making of MRP through CAD / CAM procedure gives maximal result resembling the form of mandibular model. The MRP models get an accurate picture of the patient’s jaw as a pre contour tools for reconstruction plate. The formation of the reconstruction plates (precontour) with these MRP model is obtained from CAD / CAM and provides a normal jaw image, so that preoperative precontouring will give good and maximum result on the reconstruction plates made under the MRP models.

This study evaluated the outcomes of computer-aided design–computer-aided machining (CAD-CAM)–customized titanium mesh used for prosthetically guided bone augmentation related to the occlusion-driven implant position, to the vertical bone volume gain of the mandible and maxilla, and to complications, such as mesh exposure. Nine patients scheduled for bone augmentation of atrophic sites were treated with custom titanium mesh and particulate bone grafts with autologous bone and anorganic bovine bone in a 1:1 ratio prior to implant surgery. The bone volume needed to augment was virtually projected based on implant position, width, and length, and the mesh design was programmed for the necessary retaining screws. After 6 to 8 months, bone augmentations of 1.72 to 4.1 mm (mean: 3.83 mm) for the mandibular arch and 2.14 to 6.88 mm (mean: 3.95 mm) for the maxilla were registered on cone-beam computerized tomography. Mesh premature (within 4 to 6 weeks) exposure was observed in 3 cases and delayed (after 4 to 6 weeks) in 3 other cases. One titanium mesh was removed before the programmed time but in all augmented sites was possible implant insertion. No complication occurred during prosthetic follow-up. Using CAD-CAM technology for prosthetically guided bone augmentation showed important postoperative morbidity of mesh exposure (66%). Because of this high prevalence of mesh exposure and the potential infection that could affect the expected bone augmentation, this study suggests a cautious approach to this procedure when designing the titanium mesh, to avoid flap tension that may cause mucosal rupture.

Design Aspect

Computer-Aided Design (CAD) is the essential tools to create technical documentation and product specification for designing a product. Because of this, a survey conducted to identify the needs and importance of the design aspect such as design requirement, design concept, detailed product design and design evaluation. The result of a descriptive analysis indicated that significance of the elements of designing the quality product was at a high level. Findings also state that there was a positive relationship between the design process among each aspect of the product design, and the correlation shows a moderate level.
