Simplified Versus Conventional Technique for Complete Denture Fabrication.
Condition: Edentulous
MeSH terms: Mouth, Edentulous
Study type: Interventional
Phase: Phase 2

Summary: 
      The purpose of this study is to evaluate the effectiveness of a simplified technique of
      conventional dentures fabrication, comparing it to a traditional technique, by evaluating the
      impact of oral health on quality of life, satisfaction of individuals and chewing efficiency
      as well assessing the quality of prosthetics and TMD. Furthermore, the cost involved in the
      manufacture of dentures through technique simplified will be compared to the cost involved in
      the traditional technique.
    

Detailed description: 
      The traditional technique will be conducted through a protocol used by most dental schools in
      Brazil and described in some clinical trials as a conventional technique for dentures
      fabrication. On simplified technical functional molding step is deleted, and thus the
      orientation planes are made directly on the resulting models of the initial molding alginate,
      and the mounting of the models is performed in semiadjustable articulators random with the
      aid of an auxiliary table 15 degrees with semiadjustable articulators fixed to the slope. To
      evaluate the impact on oral health quality of life of individuals will be used the Brazilian
      version of Oral Health Impact Profile for edentulous patients (OHIP-Edent) for evaluation of
      patient satisfaction will use a specific questionnaire assessing the quality of the
      prostheses will be carried out through a specific exam, to assess the presence of TMD, all
      subjects will be evaluated through the RDC / TMD, for assessing the efficiency masticatory
      chewing capsules are used, the costs involved in the manufacture of prostheses will be
      calculated according to the material consumption used during the making of the prosthesis.
      All subjects will be assessed before making the prostheses and 90 days after installation of
      new dentures during this period will be held regular control visits. The data will be
      evaluated in order descriptive by numbers and proportions, moreover, it will be statistically
      evaluated by means of suitable tests.
    

Intervention name(s): Complete conventional dentures; Complete simplified dentures
Intervention type(s): Device; Device
Intervention description(s): The typical operations of conventional technique will be carried out dentures fabrication and clinical appointments and laboratory steps will be necessary until denture insertion:
Preliminary impression using irreversible hydrocolloid in a stock trays; Individual acrylic resin trays fabrication; Functional impressions using Zinc oxide-eugenol paste and low fusion compound in a individual acrylic resin trays; Maxillary occlusion rims fabrication; Maxillary occlusion rims fabrication adjustments, Centric relation records and transference of the maxillary occlusion rims positions to semiadjustable articulators using a facebow; Setting of teeth in wax; Complete denture wax try-in; Insertion, instructions and postinsertion appointments.; For a complete simplified denture fabrication, individual acrylic resin trays fabrication and functional impressions steps will be deleted, and the facebow for transference of the maxillary occlusion rims positions to semiadjustable articulators will be replaced by the table Camper.
