Spiral or Cone Beam CT (CBCT) data sets of the patient jaw bones and of the scan template are transcoded by a specific software to produce three-dimensional (3-D) images of the jaw bones and thickness of the mucosa. Software planning...
The scientific literature shows that short implants with a length of ≥ 6 mm are able to support prosthetics in the edentulous mandible. After tooth removal the mandible displays different degrees of atrophy (Fig 1&2). Regarding hard tissue management...
3-D imaging seems the best option unless clinical examination reveals an ample bone volume. The bone quality can be derived from density measurements if CT scan images are available or approximately from the trabecular pattern of 2-D images. Pano....
Teeth extractions are followed by a reduction of the bucco-lingual as well as the vertical dimension of the residual alveolar ridge. The ensuing resorption is progressive and even the basal jaw may become involved. In the lower jaw, the....
At the beginning of the recall control it is necessary to define the intention of a radiograhical control and if it is needed. Radiological controls are only justified in the presence of certain symptoms, anamnesis and/or clinical examination...
Addressing the patient’s chief complaints satisfactorily and meeting patient expectations lies at the core of all dental therapy. The best way to ensure that patient expectations are met or exceeded is by thoughtful listening during the diagnosis...
The trial placement appointment is crucial for successful edentulous patient care.
The tooth arrangement (set-up) provides a tangible orientation index of the teeth’s spatial positions in relation to each...
A fixed prosthesis offers benefits from both a functional and esthetic point of view and may be regarded as quite similar to a patient's own natural dentition when compared to alternative treatment options such as complete dentures....
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...
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...
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...
