  • rehabilitation for a scleroderma patient with severe microstomia using digital and conventional methods
    Journal of the American Dental Association, 2020
    Co-Authors: Yan Zhang, Jun Luo, Yumei Zhang
    Abstract:

    Abstract Background Microstomia is a principal clinical symptom in patients with scleroderma. It is characterized by an abnormally small mouth opening, which makes traditional prosthetic rehabilitation difficult. Methods First, the primary impression and Jaw Relation Record were acquired using an intraoral scanning technique and the primary diagnostic dentures were fabricated using 3-dimensional printing (3DP). The definitive impression and Jaw Relation were obtained and digitally scanned. The second diagnostic denture was also made to confirm the esthetic and occlusal effects. Next, the adjusted dentition parts were scanned and milled from a cross-linked polymethyl methacrylate disk. In addition, the titanium alloy frameworks were also fabricated using 3DP. With flasking, the milled dentition parts were inserted and the definitive dentures were finally fabricated and delivered to the patient. Results The authors constructed the definitive removable partial dentures successfully using the digital methods of intraoral scanning, computer-aided design, and 3DP. Conclusions and Practical Implications These digital methods provide an alternative option for prosthetic rehabilitation in scleroderma patients with severe microstomia.

  • digital impression and Jaw Relation Record for the fabrication of cad cam custom tray
    Journal of Prosthodontic Research, 2018
    Co-Authors: Manabu Kanazawa, Maiko Iwaki, Toshio Arakida, Shunsuke Minakuchi
    Abstract:

    Abstract Purpose This article describes the protocol of a digital impression technique to make an impression and Recording of the Jaw Relationship of edentulous patients for the fabrication of CAD/CAM custom tray using computer-aided design and manufacturing (CAD/CAM) technology. Methods Scan the maxillary and mandibular edentulous Jaws using an intraoral scanner. Scan the silicone jig with the maxillary and mandibular Jaws while keeping the jig between the Jaws. Import the standard tessellation language data of the maxillary and mandibular Jaws and jig to make a Jaw Relation Record and fabricate custom trays (CAD/CAM trays) using a rapid prototyping system. Make a definitive impression of the maxillary and mandibular Jaws using the CAD/CAM trays. Conclusions Digitalization of the complete denture fabrication process can simplify the complicated treatment and laboratory process of conventional methods In addition, the proposed method enables quality control regardless of the operator's experience and technique.

  • Jaw Relation Record evaluation with block teeth
    Journal of Prosthetic Dentistry, 1993
    Co-Authors: Oskar Sykora
    Abstract:

    ing machine. It is not necessary to use a whole piece of thermoplastic material. 2. It is a fast and easy way to fabricate a template. Dental assistants can make one easily. 3. If a clear thermoplastic material is used, the dentist can observe whether there is adequate reduction for a provisional fixed partial denture. 4. The dentist may choose from different thicknesses of thermoplastic materials according to the clinical requirements. The only disadvantage is that this method cannot be used for a long-span fixed partial denture because it is difficult to soften a large area of thermoplastic material uniformly.
