One of the most crucial factors that will help determine the overall success of teeth implants would be the maintenance and achievement of stability for the implants that were installed. The degree of stability of teeth implants is basically presented through the use of an ISQ or Implant Stability Quotient value. Other types of contributing variables towards the success of the installation of dental implants, as with other varieties of surgical procedures, will include the patient’s general health condition and the degree as to which he or she complies with the post-surgical care procedures that are recommended by the dentist.
The use of a computer simulation program that is tailored based on information obtained from a CT scan allows the virtual surgical installation of the teeth implants according to CT scan information makes it possible for a virtual surgical placement of teeth implants that is based on a barium impregnated prototype with the last prosthesis. This is basically done to determine bone quality, embed characteristics, important anatomy, and the need for a bone graft. Moreover, this is also performed so as to maximize the surface area of the bone where the implant will be placed so as to create a higher level of predictability. Computer system CAD or CAM milled or stereolithography dependent drill guides may also be developed so as to aid the surgeon to facilitate the proper placement of teeth implants based on the occlusion and aesthetics of the final prosthesis.
Software that makes a treatment plan can also be employed in demonstrating the “try-ins” to a patient on a computer screen. When the different options have been discussed by the surgeon to the patient, the same computer program can be used in coming up with precise drill guides. Specialized computer software such as SimPlant and NobelGuide utilize the data from a patient’s CBCT in making a specific treatment plan for him or her. After this, a data set is then made and sent to the lab for the production of an accurate drill guide.
For teeth implant treatments to be successful, there should be enough bone within the patient’s jaw. Moreover, the bone should also be strong enough so as for it to adequately hold and support the implants that will be installed. If enough bone mass is not present, more of this may be added by the surgeon through the use of a bone graft. The process of bone grafting is also referred to as bone augmentation. On the other hand, natural teeth and supporting tissues near the site where the implant will likely be installed by the surgeon must be in good condition.
In all situations or cases, a good amount of consideration must be made to the final functional points of the procedure. These considerations include the forces that will be placed on the teeth implants such as chewing and parafunction or abnormal grinding or cleaning habits. This need to be looked into since these forces may exceed the biomechanic tolerance of the teeth implants, which may in turn cause failure.
