1. Does traumatic occlusal forces lead to peri-implant bone loss? A systematic review
Abstract Observational studies have indicated that crestal bone level changes at implants are typically associated with clinical signs of inflammation, but still mechanical overload has been described as possible factor leading to hard–tissue deficiencies at implant sites without mucosal inflammation. The aim of this paper was systematically review the lit

2. Biomechanics of extra-alveolar mini-implants
RESUMO É inegável que a ancoragem com mini-implantes extra-alveolares revolucionou a nossa especialidade. No mesmo sentido, o correto entendimento da biomecânica com mini-implantes permitiu ampliar a gama de movimentos dentários como nunca visto na prática clínica. Deve-se, porém, atentar às diversas possibilidades dos sistemas de aplicação das for

3. Comparison of two asymmetric headgear force systems: A finite element analysis
Resumo Objetivo: o objetivo desse estudo foi usar o método de elementos finitos 3D para avaliar o efeito no padrão de deslocamento dos molares em resposta ao uso de aparelhos extrabucais com diferentes forças assimétricas. Métodos: foram confeccionados 25 aparelhos extrabucais (AEB) com diferenças, entre os lados direito e esquerdo, quanto ao compri

4. Influence of dental occlusion on the athletic performance of young elite rowers: a pilot study
OBJECTIVES: The present study aimed to assess the influence of dental occlusion on body posture and the competitive performance of young elite rowers. METHOD: Dental occlusion disturbance devices were used to simulate dental malocclusions. We assessed the influence of malocclusion on the body balance, paravertebral muscle contraction symmetry, and muscular

5. Case study of muscle fatigue in parafunctional patient using occlusal device with fiber Bragg grating sensors
Abstract This case study describes a new method using a fiber optic Bragg grating sensor to determine muscle fatigue in a patient wearing a resilient occlusal device for the treatment of bruxism symptoms. Four tasks performed at maximum bite force induced rapid exhaustion for the analysis of fatigue. The results show that it is possible to obtain a better un

6. 3-D finite element analysis of the effects of post location and loading location on stress distribution in root canals of the mandibular 1st molar
Abstract Objective The purpose of this study was to evaluate, by using finite element analysis, the influence of post location and occlusal loading location on the stress distribution pattern inside the root canals of the mandibular 1st molar. Material and Methods Three different 3-D models of the mandibular 1st molar were established: no post (NP) – a

7. The force magnitude of a human bite measured at the molar intercuspidation using fiber Bragg gratings
Abstract This study describes a localized method – using optical fiber Bragg gratings (FBGs) – to determine the human bite force at the very moment of occlusion, in maximum intercuspidation. The FBG was encapsulated in a silicone splint between uppers and lowers first molars and avoiding pre-contact with the other teeth in a dentition model. Gypsum denta

8. Three-dimensional analysis of an orthodontic delta spring
INTRODUCTION: The purpose of this study was to analyze the force system, moment-force ratios (M/F) and von Mises stresses in an orthodontic delta spring using a 3D finite element model. The M/F ratio produced by an orthodontic spring is related to the different types of tooth movement that are likely to occur in the sagittal and occlusal planes. METHODS: Ana

9. Effect of veneering material on the deformation suffered by implant-supported fixed prosthesis framework
Knowing how stresses are dissipated on the fixed implant-supported complex allows adequate treatment planning and better choice of the materials used for prosthesis fabrication. Objectives: The aim of this study was to evaluate the deformation suffered by cantilevered implant-supported fixed prostheses frameworks cast in silver-palladium alloy and coated wi

10. Load-bearing capacity of screw-retained CAD/CAM-produced titanium implant frameworks (I-Bridge®2) before and after cyclic mechanical loading
Implant-supported screw-retained fixed dental prostheses (FDPs) produced by CAD/ CAM have been introduced in recent years for the rehabilitation of partial or total endentulous jaws. However, there is a lack of data about the long-term mechanical characteristics. OBJECTIVE: The aim of this study was to investigate the failure mode and the influence of exten

11. Análise eletromiográfica e de força de mordida de pacientes acometidos por desordens temporomandibulares submetidos ao tratamento com placa oclusal / Electromyographic and bite force analysis of patients suffering from temporomandibular disorders undergoing treatment with occlusal splints
The diagnosis of temporomandibular disorders is based on the information collected about symptoms during clinical examination of the occlusion and radiological examinations of the temporomandibular joints. In the search for better understanding of the pathophysiology that affects the muscles of the stomatognathic system, electromyographic analysis has been i

12. Chewing side, bite force symmetry, and occlusal contact area of subjects with different facial vertical patterns
Craniofacial dimensions influence oral functions; however, it is not known whether they are associated with function asymmetry. The objective of this study was to evaluate chewing side preference and lateral asymmetry of occlusal contact area and bite force of individuals with different craniofacial patterns. Seventy-eight dentate subjects were divided into
