Simplified Versus Conventional Technique for Complete Denture Fabrication.

7 de enero de 2016 actualizado por: Ana Luísa de Barros Pascoal, Universidade Federal do Rio Grande do Norte

Quality of Life, Patient Satisfaction, Quality of Dentures, Masticatory Efficiency, Presence of Temporomandibular Dysfunction and Costs Analysis of Simplified and Conventional Techniques for Complete Denture Fabrication

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.

Descripción general del estudio

Descripción detallada

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.

Comparador activo: Complete conventional dentures
Complete dentures fabricated by conventional technique.

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.

Medida Descripción
Periodo de tiempo
Quality of life
Periodo de tiempo: Baseline = day 0
To assess the impact of oral health on quality of life individuals will be used the Brazilian version of Oral Health Impact Profile for edentulous patients (OHIP-Edent). The inventory shall be applied by a masked examiner.
Baseline = day 0
Patient satisfaction
Periodo de tiempo: Baseline = day 0
Patient satisfaction about complete dentures will be access using a questionnaire that assesses aspects related to overall quality of prosthesis, as well as comfort, aesthetics, retention, phonetics and mastication.
Baseline = day 0
Masticatory efficiency
Periodo de tiempo: Three months
The evaluation of the masticatory efficiency will be conducted through chewing capsules.
