“Computer assisted navigation systems” are prevalent in the surgeries of nose, ear, orthopedics, throat and neurosurgeries (Kelly, 1995). In the arena of oral and maxilla-facial surgical treatments, the technology of navigation is generally used with triumph in “arthroscopy” of the joint between temporal bone and mandible, in the surgery management of post-traumatic abnormalities of the “Zygomatic Bone”, in “Orthognathic Operation”, and for osteotomies, surgery for tumors, biopsies, distractions, punctures, and elimination of unfamiliar organisms (Wagner, et al, 2001).
The computer-aided maxillofacial surgery can be advantageous for the dental implants.
Impact of Computer Aided System in Dentistry
Nowadays an obvious tendency in the utilization of computer assisted navigation in the implantology of dentistry could be examined. For the purposes of researches and for employment by marketable businesses, systems of navigations are constructed that supply software and hardware built up to place the dental plants. An extensive benefit of this navigation is accurate planning prior to surgery, which is maximized via considering its aspects of function and prosthesis. This is of critical significance to an adverse automatic freight which could bring about peri-implant atrophy of bone and as a result failure of implant at earlier stages (Hobkirk & Havthoulas, 1998).
In addition, the systems of navigation enhance the intra-operative security, for the reason that injury to vital structures of anatomy for instance the nerves, or adjacent incisors can be evaded. The accurateness achievable through the computer assisted systems of navigation has been explored in a number of researches and discovered to be adequate. For instance, Wagner et al (2003) state, in an assessment of around 32 implants of endosseous placed under the supervision of navigation system, an average variation of 1.1 mm mutually at the apex and bottom of the plants in vestibular and lingual track.
Efficiency and Effectiveness
Developments in technology strongly influence the up-to-date field of medicine. This is particularly clear in the technology of imaging. An important part of the clinical use of this technology is the planning and surgical simulation. The objective of surgical planning is to optimize results. A prerequisite for planning successful surgery is the preparation of images Preoperative. For the segmentation of data image, a single pixel is assigned to certain tissues two as skin, bone, structures at risk, tumors, etc... Powerful graphics programs are necessary for interactive manipulation high resolution. Using a model of the patient you generated with the CT or MRI data, the definition of the surgical goal and planning can be made. Despite this, we must remember that models are approximations of the patient and the accuracy is limited by the thickness of the cuts in relation to particular structures (e.g. the pa- orbital networks and sinuses, etc...).
Access to Care
The pattern of the provision of service may reveal a difference among private and public patients of dentistry. To a certain extent, these reproduce the dilemmas of constraints of the resources in the community segment wherever there is a larger dependence on care in urgent situation that is revealed in a advanced ...
