Presence/number of implants influences aerobe and anaerobe species in saliva and on tongue in edentulism. Subgingival microbiota in periimplantitis vary according to studies. Less periodontal pathogens than in partial edentulism. Prevotella nigrescens,...
All tissue surfaces, prosthesis surfaces and implant surfaces should be accessible by oral hygiene aids like toothbrushes, interdental brushes and dental floss or dental tape. It is paramount that, during treatment planning...
The regular recall control appointment, at least every 6 months, should comprise a hygiene check by the dental/oral hygienist or other auxiliary, and include professional cleaning of the restoration, prosthetic components, sulcus and any...
Flapless implant surgery is a minimally invasive procedure that can be performed either using guided surgery or custom fabricated surgical guides made of casts taken at the first patient visit. Several clinical papers reported excellent short- and long...
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...
Smoking and nicotine consumption have a constrictive effect on blood vessels thereby reducing blood supply. It increases the susceptibility to periodontal inflammatory diseases, dry extraction sockets and wound healing...
