Immediate Loading with Intraoral Welding for Improved Implant Stability during Healing
International Journal of Oral Implantology & Clinical Research, 2011
Purpose: A clinical case is presented demonstrating the utilization of intraoral welding (syncrystallizer) to stabilize immediate one-piece implants during osteointegration for a fixed full-arch upper and lower rehabilitation with flapless surgical approach. Materials and methods: The surgical and prosthetic technique including postextraction placement of one-piece implants, modification of the implants intraorally for prosthetic angulation, and the method of initial bracing the implants, is described. The procedure has been subdivided by arch, with each arch being treated in a similar manner during a single surgical appointment for the full mouth implant treatment. Outcome: No complications are reported, and no implant has been lost one and a half years following surgical placement and restoration. The patient maintains appropriate oral hygiene and is pleased with the functional and esthetic results. The radiographs demonstrate maintenance of the osseous crestal levels with no peri-implant bone loss. Conclusions: The technique has demonstrated an effective aid for immediate implant stabilization allowing immediate loading without hampering the osteointegration process.
Prosthesis
The need to modify removable partial dentures equipped with a metal framework in order to add other prosthetic teeth to replace natural teeth lost by the patient could lead to laboratory procedures so complex as to require the creation of new prostheses with a heavy economic burden. The creation of preformed metal pins to be welded using the economical TIG cold welding method could represent a valid alternative solution with the aim of modifying the prostheses using a reinforced resin capable of adequately resisting masticatory loads. This study evaluates and compares the mechanical robustness and the clinical reliability of these modified prostheses in cases of junctions of one or two contiguous prosthetic teeth. The 6-month follow-up demonstrated the total validity of the method via the absence of significant breakages or detachments in all of the patients analyzed; on the other hand, the prostheses modified using the traditional method and used as controls showed a high incidence...
Proposed technique for fabricating complete denture
Introduction: Reduction of the visits for fabricating complete dentures are welcomed by both dentists and patients and this might be an aspect of the new changes in prosthodontic treatment according to the suggested new methods. Clinical Innovation: Complete dentures fabricated by the technique described in this report reduce processing time, cost and efforts since the technique does not require the use of gypsum materials, metal flasks or other related materials to obtain a mold for packing the heat cured acrylic resin as might be needed with the conventional method. This method requires only an appropriate volume of silicone impression material to provide the required mold and a heat pressure machine for processing and polymerization of the heat-cured acrylic resin. Although this technique might be difficult to be applicable by all dentist but it could be consider an advisable method. Discussion: Because the record base in this technique is made of heat cured resin, it provides a reliable denture base with better retention and stability and it overcomes the shortcomings that may be faced during registration of vertical dimension. This technique meets the basic requirements for a successful complete denture which is well tolerated by the patient’s mouth. Key words: Acrylic, denture, polymerization, technique
Immediate denture fabrication: a clinical report
Annali di stomatologia
The aim of the present clinical report was to describe the use of a patient's extensive fixed prosthesis, where the supporting teeth were hopeless, for fabricating an interim immediate complete denture. The present procedure was used to replicate the vertical dimension, phonetic and aesthetic of the existing fixed prostheses as part of an immediate denture and a final complete denture.
Journal of Prosthetic Dentistry, 2010
Prosthesis fracture is a common complication associated with implant-retained overdentures. A new overdenture can be strengthened by incorporating a cast metal reinforcement during processing. The authors describe a technique for converting an existing conventional nonreinforced serviceable denture into an overdenture that includes a cast metal reinforcement and its attachments.

Fabrication of an Immediate Denture: A Case Report
2020
The aim of this clinical report is to describe the use of a patient's fixed prosthesis, where the supporting teeth were having poor prognosis. The patient was convinced for fabricating an interim immediate complete denture followed by fabrication of permanent complete denture. The present procedure was used to replicate the vertical dimension, phonetic and aesthetic of the existing fixed prostheses as part of an immediate denture and a final complete denture.
New clinical technique for fabrication immediate partial denture
Immediate partial denture is a choice of treatment due to various cases of teeth extraction such as badly carious teeth, periodontal disease, eruption problems, trauma, and other reasons. Many choices are used to replace the lost teeth; one of these choices is a removable plastic denture in which hot cured acrylic resin should be used to fabricate such denture. Aim of Study: To provide an applicable technique to fabricate an immediate partial denture by reducing and declining the prosthetic steps and some materials in proportional to the conventional method. Clinical Procedures: Maxillary and mandibular stone casts are mounted to a simple articulator and the procedures are explained as step by step to fabricate an immediate partial denture without using the conventional methods and material, just using a small quantity of white cold cure acrylic resin to fabricate the artificial teeth, hot cure acrylic resin for the denture base and mold made of a silicon impression material are used to fabricate an immediate partial denture. Conclusion: The finished immediate partial denture showed a good retention and produced the exact shapes and sizes of the extracted teeth with low cost and less time for a dentist and patient.
