A randomised crossover clinical trial of masticatory function in complete denture wearers with conventional and lingualised balanced occlusion.

Objectives: The purposes of the present study were as follows: (1) to conduct a randomised crossover clinical trial to evaluate masticatory performance in wearers of conventional complete dentures in both arcs with conventional balanced occlusion (CBO) and lingualised balanced occlusion (LBO), using almonds as natural test food chewed for (a) 30 chewing cycles, (b) 40 chewing cycles and (c) until the subject felt ready to swallow and (2) to perform a randomised crossover clinical trial of oral health self-perception through the Geriatric Oral Health Assessment Index (GOHAI) questionnaire.

Background: During rehabilitation with full dentures, achieving stability and retention is essential for masticatory performance. A factor that can act is the appropriate occlusal scheme to be used, although the literature is full of discussions as to the most suitable occlusal scheme to be used, being CBO and LBO the most used in complete dentures.

Masticatory efficiency in complete denture and single implant-retained mandibular overdenture wearers with different occlusion schemes: A randomized clinical trial.

Statement Of Problem: How the masticatory function of complete denture wearers is influenced by the positioning and occlusion of posterior teeth or by the presence of a single mandibular implant is unclear.

Purpose: The purpose of this randomized crossover clinical trial was to evaluate the masticatory efficiency of wearers of bimaxillary complete dentures and of wearers of maxillary complete denture and single implant-retained mandibular overdentures, both with bilateral balanced occlusion and lingualized occlusion.

Material And Methods: Participants received 2 sets of complete dentures with interchangeable teeth in the mandibular prosthesis to allow a change in the occlusion scheme.

Mechanical Behavior of Ceramic Monolithic Systems With Different Thicknesses.

Objectives: This study assessed the fully stabilized zirconia (FSZ) Prettau Anterior, the partially stabilized zirconia (PSZ) Prettau, and the lithium disilicate IPS e.max CAD (LD) through microstructural and mechanical characterization and effect of thickness on fracture load of the ceramics.

Methods And Materials: Disk-shaped specimens (12 mm diameter and 1.

Implant-supported double-bar overdenture to reestablish lip support in an atrophic maxilla: a case report.

Prosthodontic treatment for edentulous maxillae with severe bone loss is a challenge to clinicians. Although implant-supported, fixed maxillary complete dentures are increasingly common, they are not always able to provide adequate lip support without a buccal overextension in patients with bone loss. The overextended buccal flange makes it difficult for patients to clean under the prosthesis.
