Diagnosis is a Greek word that means discern or distinguish; thus, diagnosis is a cognitive experience. The diagnostic process was originally based on interrogation, inspection, auscultation, olfaction and palpation. With advancement in medical...
Fully edentulous maxilla - a "different" treatment approach
A 65-year-old female patient came for a complete-arch treatment. The aim was to re-position the old removable denture in its original position to be able to transfer it into a cement-retained provisional denture.
Conceptually, a provisional prosthesis for an edentulous patient is a convenient tool that offers the patient a satisfactory level of function and esthetic appearance while definitive treatment is undertaken...
Treatment planning for the edentulous patient requires a diagnostic tooth arrangement which provides valuable information for pre-surgical planning (surgical guide fabrication), facilitates discussion regarding...
The primary goal of creating a preliminary teeth arrangement for a try-in diagnostic evaluation is the opportunity to visualize those specific morphological features that impact functional and esthetic considerations for each treated patient...
Tomography represents 2-D images of a slice through an object. Computerized tomography (CT) can produce virtual slices and conventional CTs take slice by slice and the machine stops and moves in between slices. Spiral/helical CTs are continuous scans in a...
Radiation source collimated at its source and then diverges into a fan shape to reach detectors. This results in a cone beam.
Pixel (picture + element) is the smallest single component of a 2-D image, whereas a voxel is the smallest element...
When obtaining a panoramic film, one must be aware of the importance of following proper technique and carefully positioning the patient's skull between the X-ray generator and the film. Rotation of the film and radiation source often occurs along a...
Intra-oral radiography can provide sufficiently diagnostic information regarding a dentition and also, in many instances, also yield the necessary pre-surgical planning information for implant surgery. If panoramic radiography is not available...
Because any form or radiation can impose a risk, patient history and clinical examination should be performed first to ensure that the right kind of imaging is sought and unhelpful imaging is avoided.
The four main types of imaging tools utilized, and...
Physiological salivary output is 0.75 to 1.5 liters per day, with most originating from the submandibular glands. Saliva is a lubricant and has a complex set of protective and healing functions for the oral cavity. It adheres instantly to...
Epithelial desquamation in the oropharynx limits bacterial accumulation, except on the tongue dorsum and in the tonsillar crypts. Loss of teeth dramatically reduces the load of periodontal pathogens except for Aggregatibacter actinomycetemcomitans and to a...
Radiographical check-ups to evaluate bone levels cannot be repeated too often to avoid unnecessary radiation. Monitoring the overlying soft tissues may help to identify eventual problems of the underlying bone, although the correlation...
Head and neck cancers is mainly represented by head and neck squamous cell carcinoma (HNSCC). Incidence in males is higher than in females (2,8:1). Human papilloma virus (HPV) has been demonstrated to be related to the increased...
A universally accepted definition of ideal occlusion has been elusive. This is because an ideal occlusion can only be defined in broad terms of a physiological range of form and function. Functional aspects of occlusion, rather than specific anatomical...
