Background and purpose: Transverse problems in the maxilla (high arched- narrow hard plates) can cause respiratory disorders. Palatal expansion can be helpful in this way. The present study aimed at evaluating the effect of bone borne expansion and tooth borne palatal expansion on airway volume. Materials and methods: A review study was performed by search in Google Scholar, Scopus, PubMed, Em...

The aim of this article was to describe the process designing and manufacturing 3D TPAs discuss some clinical cases in which were used. Digital models acquired by scanning casts, PVS impressions or dentitions directly. data a common STL format used for computer design that follows. Then, instructions sent printer fabrication. Finally, manual polishing should be performed. Seven assist orthodont...

Palatal rugae, are the ridges on the anterior part of palatal mucosa, each side of the median palatal raphe and behind the incisive papilla. Rugae patterns have been studied for various purposes, and have been established to have a role in positive identification of individuals in suspected cases. The present study aims at determining the effect of growth, on palatal rugae patterns and to analy...

OBJECTIVE To compare single buccal articaine injection versus conventional lignocaine buccal and palatal injections for uncomplicated maxillary tooth extractions. STUDY DESIGN Single blinded randomized control trial. PLACE AND DURATION OF STUDY The outpatient department of Oral and Maxillofacial Surgery, Armed Forces Institute of Dentistry, Rawalpindi, from February to September 2011. MET...

An ectopic tooth is one that erupting in an aberrant route, whereas impacted has failed to fully erupt into the oral cavity within its expected developmental time period and can no longer be do so. The majority of canine eruption abnormalities occur two directions: palatal or buccal displacement from usual eruptive location 2. Permanent maxillary impaction affects about 1-2 percent general popu...

INTRODUCTION This study was carried out to evaluate the treatment changes in skeletal and dental parameters in growing patients. METHODS The sample consisted of 24 subjects with Class II Division 1 malocclusion. Half of the patients were treated with cervical headgear alone (group C, n = 12), and the other half received a combination of cervical headgear and lower utility arch (group CU, n = ...

Figure 1.Maxillary PVS impression demonstrating defect in palatal region. A maxillary complete denture (CD) impression often demonstrates a defect in the palatal region of the edentulous arch. This problem commonly relates to air trapped in the impression material or mishandling of the tray seating; the bubble formed in the impression can compromise the fit of the CD or impair tissue health. On...

The aim of the present study was to examine dentoalveolar development in subjects with an 'ideal' (normal) occlusion. The material comprised 436 study casts of 189 male and 247 female subjects of Swedish origin between the ages of 5 and 31 years with no history of orthodontic treatment. Tooth width, and arch length, width, and depth, as well as palatal height were measured. The data were analys...

OBJECTIVE To determine the diagnostic value of 2 intraoral bisecting angle radiographic views in comparison with periodontal probing for the assessment of periodontal attachment of the canine teeth in dogs. STUDY POPULATION 466 canine teeth from 117 dogs. PROCEDURE Periodontal probing measurements were recorded, and clinical attachment levels (CAL) were calculated at the mesial, buccal, dis...

AIM To evaluate the methodological feasibility of a RCT comparing skeletal changes of nasal cavity size obtained with RME and SME, assessed via CBCT. MATERIALS AND METHODS Twenty Caucasian children with a mean age of 10.4 years were recruited and allocated to receive RME (10 subjects, mean age 10.4 years) or SME (10 subjects, mean age 10.5 years). INCLUSION CRITERIA constricted maxillary ar...
