To correct the malocclusion is the chief aim of an orthodontist. For each individual, ideal facial esthetics would result when the teeth were placed in ideal occlusion. Malocclusion is caused by two ways either spacing or crowding in which crowding is the most common cause.Treatment of a crowded arch requires space gaining.

متن کاملFirst or second premolar extraction effects on facial vertical dimension.
If the concept of mesial movement of molars to reduce the "wedge effect" and decrease facial vertical dimension (FVD) is valid, it is important to investigate the effect of first (P1) and second premolar (P2) extraction on FVD. This study compares the mesial movement of molars and changes in FVD between P1 and P2 extraction groups in Class I malocclusion with a hyperdivergent facial type. We co...
متن کاملMaxillary First Premolar with Three Root Canals: a Case Report
The maxillary first premolar is the most commonly bi- rooted tooth with occasional presentation of three roots system; it is a transitional tooth between incisors and molars. Although it usually has two canals, it may rarely have three and this third canal can easily be missed. Thus meticulous knowledge of tooth morphology, careful interpretation of angled radiographs, proper access cavity prep...
متن کاملHorizontal Root Fracture in Maxillary First Premolar: a Case Report
Horizontal root fractures of the posterior teeth are rare and occur due to severe trauma. We report herein a case of horizontal root fracture in the middle third of a two-rooted maxillary left first premolar. Since the coronal part of tooth was non-vital, calcium hydroxide was used as an intracanal medication for 10 days. Later, root canal therapy was successfully performed with mineral trioxid...
