The volume of air passing through the nose and nasopharinx is limited by its shape and diameter. Continuous airflow through the nasal passage during breathing induces a constant stimulus for the lateral growth of maxilla and for lowering of the palatal vault. Maxillary morphological differences exist between patients with airway problems and control groups, identifying a potential etiological r...

A 26 yr old female presented to the Faculty of Dental Sciences, Institute of Medical Sciences, Banaras Hindu University, Varanasi, India, in September 2015, with black discolouration of her upper gums both on labial and palatal sides. According to the patient this was present for the past four months. There was no history of smoking and drinking. A diffuse black pigmentation on the labial and p...

BACKGROUND To evaluate soft tissue conditions and bone loss around palatal positioned implants supporting fixed full-arch prostheses to rehabilitate edentulous maxillae with horizontal atrophy and compare them with conventional well-centered implants placed in non-atrophic maxillae after a minimum follow-up of 5 years. MATERIAL AND METHODS A clinical retrospective study was performed of patie...

OBJECTIVE To assess whether palatal mini-implants are effective as direct anchorage for distal movement of the upper molars. METHODS It was used an acrylic model of the upper dental arch. After making a groove in the region corresponding to dental alveolus, acrylic teeth were fixed in this groove with #7 wax, with the roots being previously immersed in adhesive wax. The orthodontic appliance ...

Mechanics using a mid-palatal temporary anchorage device (TAD) and an intrusion transpalatal arch (TPA) were applied to correct the open bites. Two different patterns could be obtained according anteroposterior position of TADs. When TAD was placed posterior first molar, teeth intruded (“posterior intrusion”), bite corrected efficiently. This is commonly used in most However, sometimes, with gu...

The aim of this case-control study was to test the hypothesis that maxillary morphology differs between obstructive sleep apnoea (OSA) patients and non-snoring, non-apnoeic subjects. Forty randomly selected patients [36 M, 4 F; mean age 49 +/- 2 (SEM) years] with varying degrees of OSA (mean Apnoea/Hypopnoea Index 32 +/- 4/hour) were compared with 21 non-snoring, non-apnoeic control subjects (1...

Objectives: Extraction of a tooth leads to a series of healing events that are intimately associated with dimensional changes in the alveolar ridge that typically result in a net volume loss. Previous studies have evaluated the extent and pattern of those resorptive changes, however it remains challenging to predict the degree of change that will occur, as numerous local and systemic factors ma...

INTRODUCTION The treatment effects and the short-term (0.9 +/- 0.45 years) relapse potential of phase I slow maxillary expansion, with a bonded palatal expander or a quad-helix appliance combined with a mandibular banded Crozat/lip bumper and followed by 12 to 15 months of retention, were examined. METHODS Pretreatment (8.8 +/- 1.7 years) and posttreatment (11.1 +/- 1.7 years) models of 54 pa...

BACKGROUND To evaluate satisfaction and quality of life in patients with palatal positioned implants supporting fixed full-arch prostheses to rehabilitate edentulous maxillae with horizontal atrophy and compare them with conventional well-centered implants placed in non-atrophic supporting fixed full-arch prostheses. MATERIAL AND METHOD A clinical retrospective study was performed of patients...
