BACKGROUND The extensive literature concerning the early treatment of anterior open bite (AOB) is still controversial and covers a wide variety of therapeutic approaches. OBJECTIVES The objective of this study was to provide a comprehensive review evaluating the effectiveness of the orthodontic correction of AOB in growing individuals. SEARCH METHODS Search was conducted on PubMed, Embase, ...

INTRODUCTION Anterior open-bite (AOB) treatment is considered challenging because of difficulties in determining and addressing etiologic factors and the potential for relapse in the vertical dimension after treatment. In this review, we compiled evidence on the long-term stability of the major therapeutic interventions for correcting AOB. Our objective was to review and compile evidence for th...

This study evaluated cephalometric differences between 113 Japanese (43 males and 70 females, aged 14.1 ± 5 years) and 106 European subjects (36 males and 70 females, aged 13.5 ± 7.3 years) using two compound angular measurements and their single components: the overbite depth indicator (ODI) for the assessment of vertical skeletal relationships and the antero-posterior dysplasia indicator (APD...

Dog-bite wounds are often left open because of their reputation for infection if primarily closed. A prospective randomized trial comparing primary closure with leaving the wound open was performed to assess infection and cosmesis. Ninety-six patients with 169 lacerations had thorough surgical debridement and irrigation of their wounds. Ninety-two wounds were sutured and 77 left open. No prophy...

BACKGROUND Orthodontic management of anterior open bites is a demanding task for orthodontists. Molar intrusion as a primary means of open bite correction entails the need for appropriate anchorage. Orthodontic mini implants can provide the required mechanical support. The suggested procedure aims to reduce the risk of complications such as root damage or soft tissue irritations while minimizin...

Moses describes an appliance termed a "passivator" which supports the mandible in an anterior and slightly open bite yet neither allows nor causes undesirable orthodontic tooth movements. This appliance is reported to support the patient’s mandible during sleep, prevent collapse of the pharyngeal musculature, allow greater volume of space for tongue activity and prevent incorrect swallowing and...

It has been postulated that dentoalveolar height is enlarged by a compensation mechanism in long face subjects. In this study, dentoalveolar composition was studied in 83 open bite patients. It was found that increases in overbite during treatment coincided with vertical lengthening of the symphysis, which exceeded increments in lower face height. This vertical growth coincided mainly with an i...

Ontogenetic studies of vertebrate feeding performance can help address questions relevant to foraging ecology. Feeding morphology and performance can either limit access to food resources or open up new trophic niches in both aquatic and terrestrial systems. Loggerhead sea turtles are long-lived vertebrates with complex life histories that are marked by an ontogenetic shift from an oceanic habi...
