Several procedures have been proposed to achieve maxillary ridge augmentation. These require bone replacement materials to be manually cut, shaped, and formed at the time of implantation, resulting in an expensive and time-consuming process. In the present study, we describe a technique for the design and fabrication of custom-made scaffolds for maxillary ridge augmentation, using three-dimensional computerized tomography (3D CT) and computer-aided design/computer-aided manufacturing (CAD/CAM). CT images of the atrophic maxillary ridge of 10 patients were acquired and modified into 3D reconstruction models. These models were transferred as stereolithographic files to a CAD program, where a virtual 3D reconstruction of the alveolar ridge was generated, producing anatomically shaped, custom-made scaffolds. CAM software generated a set of tool-paths for manufacture by a computer-numerical-control milling machine into the exact shape of the reconstruction, starting from porous hydroxyapatite blocks. The custom-made scaffolds were of satisfactory size, shape, and appearance; they matched the defect area, suited the surgeon's requirements, and were easily implanted during surgery. This helped reduce the time for surgery and contributed to the good healing of the defects.

The use of virtual surgical planning and computer-aided design/computer-aided manufacturing has been reported to enhance the planning for the reconstruction of mandibular continuity defects. This case report illustrates the use of this technology in the fabrication of a custom-made titanium prosthesis to restore a segmental mandibular defect. The design specifications and sequence of the custom-made titanium prosthesis are discussed. Although successful in this case, there are limitations in its application and case selection is of vital importance.

Anterior Mandible

This report documents the clinical, radiographic, and histologic outcome of a custom-made computer-aided-design/computer-aided-manufactured (CAD/CAM) scaffold used for the alveolar ridge augmentation of a severely atrophic anterior mandible. Computed tomographic (CT) images of an atrophic anterior mandible were acquired and modified into a 3-dimensional (3D) reconstruction model; this was transferred to a CAD program, where a custom-made scaffold was designed. CAM software generated a set of tool-paths for the manufacture of the scaffold on a computer-numerical-control milling machine into the exact shape of the 3D design. A custom-made scaffold was milled from a synthetic micromacroporous biphasic calcium phosphate (BCP) block. The scaffold closely matched the shape of the defect: this helped to reduce the time for the surgery and contributed to good healing. One year later, newly formed and well-integrated bone was clinically available, and two implants (AnyRidge, MegaGen, Gyeongbuk, South Korea) were placed. The histologic samples retrieved from the implant sites revealed compact mature bone undergoing remodelling, marrow spaces, and newly formed trabecular bone surrounded by residual BCP particles. This study demonstrates that custom-made scaffolds can be fabricated by combining CT scans and CAD/CAM techniques. Further studies on a larger sample of patients are needed to confirm these results.

BACKGROUND Nowadays, the use of computer aided design / computer aided manufacturing (CAD / CAM) in fabricating indirect restoration such as onlay, crown and bridge has increased tremendously. However, there is lack of clinical information and evidence on current material and fabrication techniques of CAD / CAM post and core. This paper describes the classification of the post and core system and review current perspectives on recent development of CAD / CAM post and core. An electronic search of the literature was performed via PubMed and Scopus database, using the keyword (post and core) and (CAD / CAM) and (CAD / CAM post and core) as MeSH term. Articles eligible for inclusion in the present review were published in English, journal article and dated from January 2000 until November 2020. A total of 31 publications consisting of 18 in-vitro studies, 7 case reports, 4 finite element analysis and 2 clinical techniques were included in this review. Analysis parameters included are options of chairside CAD / CAM materials, CAD / CAM system and milling machine used, advantages and disadvantages and future direction of CAD / CAM post and core. CAD /CAM post and core can be alternative option as compared to the custom-made post and core and prefabricated post and core. KEY WORDS Computer - Aided Design, Computer - Aided Manufacturing, Dental Material, Indirect Restoration, Post and Core
