The aim of the study was to establish the prevalence of dental features that indicate a need for early orthodontic treatment (EOT). A group of schoolchildren in the mixed dentition stage (7-11 years old) (n = 432) was clinically screened for indications for EOT. Over 1/3 of the youngsters (34.7 per cent) presented at least one of the indications for EOT: anterior and posterior crossbites (inclu...

Background The aetiology of temporomandibular joint disorders (TMD) is multifactorial, whereas occlusal disharmony is one of the predisposing factors. Researchers still discuss the relation between occlusion and TMD. Objective The study aims to investigate the relation between static occlusal parameters and TMD clinical symptoms using T-Scan II analysis system. Material and methods The samp...

BACKGROUND There have been passing references in history that excessive occlusal forces might be a causative factor in gingival recession. The purpose of the present cross-sectional study was to explore the role of trauma from occlusion on the development of gingival recession. METHODS Three hundred patients reporting to the department of Periodontics were screened for the presence of gingiva...

OBJECTIVE The purpose of this study was to evaluate the effect of occlusal contact area for loading on the cuspal defection and stress distribution in a first premolar restored with a high elastic modulus restorative material. MATERIALS AND METHODS The Rhinoceros 4.0 software was used for modeling the three-dimensional geometries of dental and periodontal structures and the inlay restoration....

AIMS To establish the minimum dimensions for a non-precious cast metal occlusal rest by using mathematical analysis. An occlusal rest in a removable partial denture (RPD) provides vertical support and allows occlusal forces to be transmitted through the long axis of the abutment tooth. METHODS The stress status of an occlusal rest in a posterior tooth-bounded RPD resembles that of a cantileve...

The pathogenesis of ‘abfraction’ has been considered to be multifactorial with contributions from occlusal loading becoming increasingly prominent in recent years. The objective of this study was to find out whether the presence of an extensive occlusal amalgam restoration and eccentric parafunctional loads would cause increased cuspal movement and therefore, increase in cervical stress exceedi...

Masticatory system function disorders, known as temporomandibular disorders (TMD) represent frequently encountered problem in daily practice. Clinicians generally agree that psychosocial factors (stress), trauma (macrotrauma any sudden force to the joint resulting in structural alteration, or microtrauma functional overloading associated with muscular hyperactivity (bruxism) or occlusal instabi...

The incidence of fractures involving the mandibular condyle are stated by most authors to be the second-most common type of fracture of the mandible with male-female ratio 2:1. Condylar fracture may results in restricted mouth opening, restricted movement of the jaw and malocclusion, Mal-occlusion following condylar trauma may result from alteration in the condylar growth center or union of the...

Teeth with vertical root fracture (VRF) have complete or incomplete fractures that begin in the root and extend toward the occlusal surface. The most frequent causes of VRF originate from physical trauma, occlusal prematurity, inadequate endodontic treatment, and iatrogenic causes. Diagnose is difficult and delay can cause stomatognathic system problem. The purpose of this case report was to ev...

Introduction: The aim of this paper is to describe a case of rehabilitation of trauma induced mandibular defect, reconstructed by distraction osteogenesis, and followed by the precise placement of implants aided with digital planning software. Case Report: In the following case report, a 56-year-old male patient with mandibular segmental defect, was treated with distraction osteogenesis followe...
