BACKGROUND AND AIM: Existence of developmental spaces during the primary dentition period is essential for the permanent dentition period and results in regular eruption of permanent teeth. The wide class of different occlusion and dental arch types during the primary dentition period, based on factors such as race, conducted to research the prevalence of these...

BACKGROUND The purpose of this study is to evaluate the relationship between dental arch form and the vertical facial pattern determined by the angle between the mandibular plane and the anterior cranial base (Sella-nasion/mandibular plane angle (SN-MP)) in skeletal class II untreated patients. METHODS A sample of 73 Caucasians patients with untreated skeletal class II in permanent dentition ...

This study was designed to clarify the three dimensional features of naso-maxillary complex in cleft lip and palate (CLP) by using computed tomography (CT) and to examine its change following an upper dental arch expansion. Sequential CT images with 2mm-thickness were obtained for 11 unilateral CLP boys (UCLP), 6 bilateral CLP boys (BCLP) and 4 boys without cleft (non-cleft). Additionally, two ...

The aim of this article was to show two cases that used a two-plan loop (T-loop modified) for correcting of dental transposition. The cases showed orthodontic treatments of transposition between lateral incisor and canine treated by two-plan loop. The loop modified showed as a good option to correct transposition with minor possibility of periodontal trauma due the horizontal movement with decr...

This case report describes a new surgical orthodontic approach involving alveolar bone distraction osteogenesis for correction of an asymmetric maxillary dental arch. The treatment was combined with conventional orthognathic surgery to improve the mandibular lateral deviation. This new treatment strategy produced an ideal dental arch and a symmetric facial appearance efficiently and effectively.

BACKGROUND AND AIM: Tooth extraction as a part of orthodontic treatment plan to create space for leveling and aligning teeth or causing tooth movement leads to changes in arch width and length. The outcome of these changes is important for the clinicians and affects the treatment and retention plans. Despite some previous studies, data in this regard are still scarce and further investigation i...

BACKGROUND Plaster casts of individual patients are important for orthodontic specialists during the treatment process and their analysis is still a standard diagnostical tool. But the growing capabilities of information technology enable their replacement by digital models obtained by complex scanning systems. METHOD This paper presents the possibility of using a digital camera as a simple i...

Objective: To highlight the advantages and disadvantages of the concept of shortened dental arch in the rehabilitation of a dentition with conventional and implant supported prosthesis, expanding treatment options to patients. Literature review: The traditional restorative concept makes the dentition a cycle of permanent repair, more than 50% of the restorative treatments consists on the repair...

This study was undertaken to examine which factors contributed to the correction of crowding in two patients who underwent nonextraction orthodontic treatment. A study model analysis was conducted to determine the effects of the orthodontic treatment for crowding with high canines on crown angulation and dental arch width in two patients. The results showed that the crown angulation was signifi...

OBJECTIVES The objective of the present systematic review was to test the hypothesis of no difference in transverse skeletal and dental arch expansion and relapse after segmental Le Fort I osteotomy versus surgically assisted rapid maxillary expansion. MATERIAL AND METHODS A MEDLINE (PubMed), Embase and Cochrane library search in combination with a hand-search of relevant journals was conduct...
