“…Also the amount of change in the class II division 1 and division 2 group from before to after treatment was not significant. Our results were contradictory to multiple studies were the palatal depth decreased with the extraction groups after treatment regardless if they were Class I, II, division 1 or 2 [31,32] this was mostly due to movement of the upper molars to a more anterior position in the extraction space, thus the molars as reference for arch depth became nearer to a shallower area of the palate. This didn't happen in our study mostly due to the operator's control on molars anchorage [10].…”

Introduction: Orthodontics has been advocating extraction as a treatment option for over a Century. Some concerns have been raised regarding dental extractions in orthodontics. Some clinicians suggested that extraction would lead to arch collapse resulting in a narrower arch width. Yet others have reported that extraction treatment to correct malocclusion will not result in arch narrowing compared with similar non extraction protocols. However, it is well accepted that extraction treatment will involve changes in the arch dimensions. Aim of the study:The aim of the current study will be directed to investigate the changes in maxillary dental arch parameters concomitant to maxillary first premolar extraction in orthodontic treatment of Angle Class II dental malocclusion. Materials and methods:This prospective clinical trial was carried out in a two arm parallel design. A group of orthodontic patients with Angle Class II dental malocclusion, Division 1 and 2 (Total N= 17) and divided into two groups division 1 (N=10) and division 2 (N=7). Records were taken before treatment and after extraction and space closure in the maxillary arch. Both groups were compared regarding Arch width, Arch perimeter, Arch length and arch depth. Conclusion:We concluded that there was no significant difference in all pre-treatment readings between Class II division 1 and division 2 groups except for Arch perimeter, Upper incisor angulation and upper incisor tip where they showed a statistically significant difference. Regarding the amount of change between pre and post-extraction measurements in for Class II division 1 there was no significant difference except for arch length, inter-canine width, and arch perimeter. The amount of change between pre and post-extraction measurements in Class II division 2 showed no significant differences.

“…The first attempt to measure palatal volume was made by Heiser et al in 2004 where the volume was measured indirectly by weight correlation . The palatal volume assessment has been done on digital study cast using 3D software programs in mouth breathing subjects, obstructive sleep apnoea patients, skeletal Class III and crossbite subjects.…”

Cleft lip and palate (CLP) is the most common birth defect affecting the face with an overall incidence of 1 out of 700 live births. The interdisciplinary treatment required in the treatment of cleft patients presents a challenge to healthcare professionals throughout the world. 1 The operated cleft lip and palate patients show a reduction in maxillary growth which is evident by midface retrusion 2 and anterior crossbite. 3 The growth inhibitory effects also extend to transverse

“…The initial weight of the model was subtracted from the final weight of the model with the silicone to obtain the silicone mass. The volume for each palate was then calculated as the mass of the silicone divided by the density (18).…”

Objective: The study objective was to assess the effect of adenoid hypertrophy on the dental arch dimensions of children in Ile-Ife, Nigeria.Methods: Ninety patients aged 3-12 years attending the Otorhinolaryngology Clinic at Obafemi Awolowo University Teaching Hospital Ile-Ife diagnosed as having hypertrophied adenoids and 90 children from the Child Dental Health Clinic were recruited as adenoid and control subjects respectively. Arch and palatal vault dimensions, including total arch length; inter-canine, inter-premolar, and inter-molar widths; palatal length; and palatal heights measured at three levels and palatal volume were determined for both groups from dental casts.Results: Maxillary arch dimensions were shorter in the adenoid group than the control group; however, only total maxillary arch length was significantly shorter (p=0.049). Mandibular arch dimensions with the exception of inter-molar width were significantly shorter in the adenoid group (p<0.05). Adenoid subjects had significantly increased palatal heights at canine, premolar, and molar levels and reduced palatal volume compared to the control subjects (p<0.05). Conclusion:Adenoid subjects demonstrated shorter maxillary and mandibular arch dimensions compared with control subjects, with the differences being more evident in the lower arch. They also exhibited increased palatal heights at all levels and reduced palatal volume compared with control subjects.
