Thus, this clinical case report aims to describe the step-by-step of rehabilitation planning of a 77-year-old male patient who was rehabilitated through maxillary and mandibular CDP after 6 months of use of the provisional CDP in the remodeling and bone resorption period. This model of rehabilitation planning allowed a functional and psychological adaptation of the patient prior to definitive reestablishment with CDP, reestablishing function, phonetics and aesthetics(AU)

Integrating 3D facial scanning in a digital workflow to CAD/CAM design and fabricate complete dentures for immediate total mouth rehabilitation

PURPOSE: To integrate extra-oral facial scanning information with CAD/CAM complete dentures to immediately rehabilitate terminal dentition. MATERIALS AND METHODS: Ten patients with terminal dentition scheduled for total extraction and immediate denture placement were recruited for this study. The patients were submitted to a facial scanning procedure using the in-office PritiMirror scanner with bite registration records in-situ. Definitive stone cast models and bite records were subsequently submitted to a lab scanning procedure using the lab scanner (iSeries DWOS; Dental Wings). The scanned models were used to create a virtual teeth setup of a complete denture. Using the intra-oral bite records as a reference, the virtual setup was incorporated in the facial scan thereby facilitating a virtual clinical evaluation (teeth try-in) phase. After applying necessary adjustments, the virtual setup was submitted to a CAM procedure where a 5-axis industrial milling machine (M7 CNC; Darton AG General) was used to fabricate a full-milled PMMA immediate provisional prosthesis. RESULTS: Total extractions were performed, the dentures were immediately inserted, and subjective clinical fit was evaluated. The immediate provisional prostheses were inserted and clinical fit, occlusion/articulation, and esthetics were subjectively assessed; the results were deemed satisfactory. All provisional prostheses remained three months in function with no notable technical complications. CONCLUSION: Ten patients with terminal dentition were treated using a complete digital approach to fabricate complete dentures using CAD/CAM technology. The proposed technique has the potential to accelerate the rehabilitation procedure starting from immediate denture to final implant-supported prosthesis leading to more predictable functional and aesthetics outcomes.

A Digital Approach to a Definitive Immediate Denture: A Clinical Report

Even though an immediate denture (ID) is a practical prosthesis, fabricating an ID may be challenging, as unexpected removals of periodontally compromised teeth may occur during an impression procedure. This clinical report introduces a digital approach to a maxillary ID. An intraoral scanner was applied to prevent accidental extraction. A physical cast and a resin pattern of a framework were fabricated with rapid prototyping technology. A proper border and retention was also achieved by an altered cast impression.

De las prótesis inmediatas a la sobredentadura: Reporte de un caso / From immediate prostheses to overdentures: Case report

En el presente artículo se describen los procedimientos clínicos y de laboratorio que se emplearon para rehabilitar a un paciente parcialmente edéntulo maxilar y mandibular. El tratamiento fue dividido en dos fases. La primera correspondió a la inserción de una prótesis total maxilar inmediata y a una sobredentadura mandibular inmediata con esquema oclusal balanceado. Una vez estabilizados los tejidos del paciente, se realizó la segunda fase del tratamiento, en la cual se cambiaron las prótesis inmediatas por una dentadura maxilar convencional y una sobredentadura dentomucosoportada retenida por aditamentos axiales radiculares. En esta segunda fase del tratamiento se reprodujo la guía anterior de las prótesis inmediatas y se empleó un esquema oclusal lingualizado. Los procedimientos descritos permiten disminuir tiempos clínicos y de laboratorio sin mermar la calidad de la rehabilitación final.

The present article purports a description of laboratory and clinical procedures used to rehabilitate a partially maxillary and mandibular edentulous patient. Treatment was divided into two phases. The first phase encompassed the insertion of an immediate maxillary total prosthesis as well as an immediate mandibular overdenture with balanced occlusal scheme. Once the patient's tissues were stabilized, the second phase of the treatment was undertaken: immediate prostheses were exchanged for a conventional maxillary denture as well as an tooth-supported overdenture retained by root-axial stud-type devices. In this second phase, the immediate prostheses' anterior guide was reproduced and a lingualized occlusal scheme was used. Described procedures allowed the decrease of clinical and laboratory time without endangering the quality of the final rehabilitation.

Immediate Dentures Using Natural Teeth - A Simple Solution.

Immediate dentures allow patient to continue their social activities without being in an edentulous state. Replacements are usually done with artificial teeth. Patients own natural teeth can also be considered as their use is well accepted by some patients. Natural teeth will retain their hue and strength for sufficient period of time to make their use practical in some instances. This clinical report describes a technique using patient’s natural teeth in fabrication of immediate removable partial denture.

Full Mouth Rehabilitation By Immediate Denture Prosthesis - A Case Report.

Esthetics plays a major concern in prosthesis. Golden guidelines of selecting and arranging teeth in natural pattern, and maintaing equilibrium of muscle forces over the prosthesis will provide good prognosis.A case in which all teeth present were of grade II and grade III mobility, immediate denture was planned to over come the social immobility. Customized bite registration tray was prepared for the record of maxillomandibular relation. All natural teeth were duplicated using selective shade of heat cure acrylic. Teeth were arranged in natural tooth pattern. Waxed up denture is acrylised and inserted soon after total extraction.

Comparison of immediate complete denture, tooth and implant-supported overdenture on vertical dimension and muscle activity

PURPOSE: To compare the changes in the occlusal vertical dimension, activity of masseter muscles and biting force after insertion of immediate denture constructed with conventional, tooth-supported and Implant-supported immediate mandibular complete denture. MATERIALS AND METHODS: Patients were selected and treatment was carried out with all the three different concepts i.e, immediate denture constructed with conventional (Group A), tooth-supported (Group B) and Implant-supported (Group C) immediate mandibular complete dentures. Parameters of evaluation and comparison were occlusal vertical dimension measured by radiograph (at three different time intervals), Masseter muscle electromyographic (EMG) measurement by EMG analysis (at three different positions of jaws) and bite force measured by force transducer (at two different time intervals). The obtained data were statistically analyzed by using ANOVA-F test at 5% level of significance. If the F test was significant, Least Significant Difference test was performed to test further significant differences between variables. RESULTS: Comparison between mean differences in occlusal vertical dimension for tested groups showed that it was only statistically significant at 1 year after immediate dentures insertion. Comparison between mean differences in wavelet packet coefficients of the electromyographic signals of masseter muscles for tested groups was not significant at rest position, but significant at initial contact position and maximum voluntary clench position. Comparison between mean differences in maximum biting force for tested groups was not statistically significant at 5% level of significance. CONCLUSION: Immediate complete overdentures whether tooth or implant supported prosthesis is recommended than totally mucosal supported prosthesis.

Single-tooth replacement in the aesthetic zone of maxilla with immediate provisionalization: a clinical study / 中华医学美学美容杂志

Objective To investigate the clinical results of immediate loading of a single anterior implant. Methods 26 implants were placed into anterior sites. Provisional prosthesis were placed at the time of fixture placement. It did not occlude in any pathway. Restoration was for esthetic only, not for function. Results No fixture was lost since the immediate restoration was delivered, the minimum being 12 months and the maximum 72 months. Conclusion Clinical studies on the placement of immediate restoration in anterior implant of maxilla have revealed predictable results.
