The theory of Guided tissue regeneration has been challenged in dentistry. The GBR principle was first examined by Dahlin et al. in 1988 on rats. The selective ingrowth of bone-forming cells into a bone defect region could be improved if the adjacent tissue is kept away with a membrane; this was confirmed in a study by Kostopoulos and Karring ...
The first membranes developed were nonresorbable and required a second surgery for membrane removal some weeks later. The need for a second surgical procedure hindered the utilization of the original barrier membranes, which led to the development of resorbable membranes; [1] research indicates no statistically significant difference in surgical success between the two types.
There are three forms of institution-based training for general dentistry available for dental school graduates in Canada: General practice residency, often abbreviated as GPR; Special Enhancement for general dentistry, often abbreviated as SEGD; Multidisciplinary training program, often abbreviated as MTP
Rotation through the dental specialties increases the resident's ability to handle situations in private practice without referral to a specialist. In both programs, the basic skills learned in dental school are improved significantly, preparing the dentist for a career in private practice or for a specialty residency program.
The American Dental Association uses the term oral and maxillofacial pathology, and describes it as "the specialty of dentistry and pathology which deals with the nature, identification, and management of diseases affecting the oral and maxillofacial regions. It is a science that investigates the causes, processes and effects of these diseases."
ConeBeam computerized tomography image of a post-operative orthognathic surgery. Oral and maxillofacial radiology, also known as dental and maxillofacial radiology, or even more common DentoMaxilloFacial Radiology, is the specialty of dentistry concerned with performance and interpretation of diagnostic imaging used for examining the craniofacial, dental and adjacent structures.
The dentist communicates with the dental technician with prescriptions, drawings, and measurements taken from the patient. The most important aspect of this is a dental impression into which the technician flows a gypsum dental stone to create a replica of the patient's anatomy known as a dental cast.
There is a great difference between the early and new hybrid composites. [5] Initially, resin-based composite restorations in dentistry were very prone to leakage and breakage due to weak compressive strength. In the 1990s and 2000s, such composites were greatly improved and have a compression strength sufficient for use in posterior teeth.
