Split obturator: An innovative approach
No full textA palatal prosthesis can improve function by closing the palatal defect, preventing regurgitation, and improving swallowing and speech. Although techniques have been previously described for fabrication of palatal obturator, but there has not been any technique to devise an obturator for a patient with palatal defect with a quadhelix orthodontic appliance overlying it. One cannot wait in such patients for completion of lengthy orthodontic treatment and then think of devising prosthesis as the patient cannot carry out normal functions like swallowing and speech without the closure of defect. This article focuses on an innovative method of fabricating a palatal obturator which aims at restoring the above-mentioned functions along with improving aesthetics. It also enables us to devise the fabrication of prosthesis in two parts for easy insertion and removal and as well as to be self-cleansable. Such prosthesis would markedly improve patient psychology and confidence
Lost salt technique for severely resorbed alveolar ridges: An innovative approach
No full textThe success of a complete denture relies on the principles of retention, stability and support. The prosthodontist skill lies in applying these principles efficiently in critical situations. Severely resorbed maxillary edentulous ridges that are narrow and constricted with increased inter ridge space provide decreased support, retention and stability. The consequent weight of the processed denture only compromises them further. This article describes a case report of an edentulous patient with resorbed ridges where a simplified technique of fabricating a hollow maxillary complete denture using lost salt technique was used for preservation of denture bearing areas. The hollowing of the denture reduces the weight of the denture, thereby enhancing stability and retention, reducing the further resorption of the jaws
Restoring Esthetics by Immediately Loaded Implant Placement
No full textThe replacement of a single missing anterior tooth with an implant-supported crown is a demanding therapy. This report describes a treatment in which an anterior maxillary implant was immediately restored with a provisional restoration. During the provisional phase, an optimal emergence profile was created by adjusting the provisional restoration. An impression was made with an individually fabricated impression post for an accurate reproduction of the established emergence profile and, finally, a screw-retained all-ceramic crown was placed. By implementing this protocol, an optimal definitive result could be achieved, together with immediate patient satisfaction.</jats:p
Peripheral giant cell granuloma
No full textPeripheral giant cell granuloma or the so-called "giant cell epulis" is the most common oral giant cell lesion. It normally presents as a soft tissue purplish-red nodule consisting of multinucleated giant cells in a background of mononuclear stromal cells and extravasated red blood cells. This lesion probably does not represent a true neoplasm, but rather may be reactive in nature, believed to be stimulated by local irritation or trauma, but the cause is not certainly known. This article reports a case of peripheral giant cell granuloma arising at the maxillary anterior region in a 22-year-old female patient. The lesion was completely excised to the periosteum level and there is no residual or recurrent swelling or bony defect apparent in the area of biopsy after a follow-up period of 6 months
Revolutionizing full-mouth rehabilitation: digital integration of Hobo’s philosophy with CAD/CAM multilayered zirconia crowns: a case report
Get PDFSevere occlusal wear disrupts function, aesthetics, and occlusal harmony. Hobo’s twin-stage philosophy offers a structured approach to full-mouth rehabilitation. Integrating this with CAD/CAM technology enhances precision and clinical outcomes. A 28-year-old male with generalized tooth wear and compromised function underwent full-mouth rehabilitation. Vertical dimension was increased by 2 mm following occlusal splint evaluation. Hobo’s twin-stage technique was applied using a semi-adjustable articulator. Digital impressions and CAD/CAM workflows facilitated the fabrication of multilayered zirconia crowns.The patient showed excellent adaptation to the increased vertical dimension. Functional occlusion with canine guidance and posterior disclusion was achieved. The final restorations demonstrated precise fit, esthetics, and occlusal stability, with high patient satisfaction. Digital integration of Hobo’s twin-stage protocol with CAD/CAM zirconia restorations offers a predictable, efficient, and esthetically superior solution for managing severe tooth wear.
Interoperator variability in shade matching for restoration with two shade guides- a study
No full textA study was undertaken in the department of Prosthodontics to compare to compare the interoperator variability in shade matching by visual techniques using two shade guides. 2 prosthodontists selected shades of upper right central incisor of 30 patients in a dental chair under ceiling daylight-corrected fluorescent lights. Two shade guides were used- Vitapan Classical and the Vitapan 3D Master shade guides (Vita Zahnfabrik). The 3 closest shade tabs were selected and ranked in order of best, second best, and third best matches. Interoperator agreement was found by comparing the best shade and the common shade for each subject by the 2 clinicians. The result was calculated using the CIE Lab color difference, ΔE*, between the best shade and the common shade selected by the clinicians for each subject. Statistical analysis was done to find clinician differences of the means of the best shade and the common shade for both shade guides using a t test (α= .05) Interoperator agreement was 32% for the best shade and over 84% for the common shade ( significant difference at the .05 level). No significant differences were found between the 2 shade guides by means of the mean color differences between the best shade match and the common shade match .Vitapan 3D Master shade guide was better than the Vitapan Classical shade guide in reducing the interoperator color differences from 0.7 to 0.2
