PURPOSE Nasal polyposis (NP) in adult population is a common problem in otorhinolaryngology outpatient practice. Computed tomography (CT) is the ideal imaging method to investigate paranasal sinus diseases. There is yet no study in the literature measuring the morphometry of maxillary bone in NP. The objectives of this study are to correlate the airway variables obtained by CT findings of both ...

Participating in the International Symposium on Early Orthodontic Treatment allowed me to review our long-term studies of orthodontic and orthopedic intervention in patients in the mixed and early permanent dentition periods who present with tooth size-arch length discrepancies. I hope this brief synopsis of that research will spur the reader to examine our textbook, a short conceptual article ...

of costal cartilages. Another problem in case of maxillectomy is the restoration of the maxillary alveolar arch. While the palate can be restored satisfactorily with soft tissue only, the cartilage and rib are inadequate as graft material when osseous-integrated implants are programmed, so this technique is unable to restore masticatory function. In our case, we performed a partial maxillectomy...

OBJECTIVE This study aimed to compare the effects of conventional and orthodontic mini-implant (OMI) anchorage on tooth movement and arch-dimension changes in the maxillary dentition in Class II division 1 (CII div.1) patients. METHODS CII div.1 patients treated with extraction of the maxillary first and mandibular second premolars and sliding mechanics were allotted to conventional anchorage...

Human embryos aged six and one-half through 12 weeks were studied to determine the morphological changes in shape of the maxillary dental arch during this early developmental period. Age was determined by crown-rump lengths using the table of Patten ('53). When compared to a reference catenary curve, the embryonic dental arch exhibited several time-linked and directional changes in shape. First...

The endodontic treatment of maxillary third molar often poses a challenge even to an experienced endodontist because of their most posterior location in the dental arch, aberrant occlusal anatomy, abnormal root canal configuration and eruption patterns. Owing to these anatomical limitations, their extraction remains the treatment of choice for many clinicians. As we know, retaining every functi...

BACKGROUND Dental crowding is the one of the most frequently encountered problem for an orthodontist. The relationship between crowding and various skeletal, dental and soft tissue parameters is important to establish and consider during the overall orthodontic treatment planning. This study aimed to determine the correlation of maxillary and mandibular base lengths with dental arch crowding in...

Alveolar bone grafting is a standard method for treating alveolar cleft. To ensure the best outcome, improving the arch form as well as soft tissue quality in the area around the cleft is recommended. In this study, 11 patients who presented with alveolar cleft and collapsed maxillary arch were treated in the following sequence: transpalatal distraction osteogenesis followed by soft tissue surg...

BACKGROUND After loss of natural teeth, provision of prosthodontic services almost becomes necessity in the present day living. To provide effective mastication teeth have peculiar forms. To make it more efficient both functionally and biologically, they are arranged in particular geometric manner referred to as dental arch. The objective of this study was to compare the distance between mesial...
