Examination of oral cavity
Examination of oral cavity before implantation usually carried out the same way as the ordinary examination of a patient with partial or fully edentulous. However, a doctor should pay attention especially to the factors that may affect the installation of implants, they are as follows:
Access
A doctor has to make sure he has adequate space for access to the proposed implantation area and manipulation associated with implants setting.
Prosthetic space
There should be enough space for suprastructures whether single crown, fixed bridge or removable denture.
Defect length
Defect length should be evaluated in terms of the possibility of subsequent implant placement.
Bone volume
There are certain minimum requirements for installing the implant and optimal requirements to help achieve the best result. A considerable assistance can provide palpation of the area prosthetic bed for determining the contours of the bone tissue in cases where it is possible. However, this method is not always feasible and does not have the required precision. It will help to identify the lack of bone only when it is clearly noticeable. Palpation method can be used as an adjunct to other methods of bone quality studies before making a decision about implant setting. Traditionally doctors use X-ray research, manufacture and test models of the prosthesis.
Bone contours
Contours of the alveolar ridge, especially in the frontal region of the upper jaw, are very important for contour crowns on the implant and may have implications for aesthetics.
Bone orientation in space
Jawbone has major and minor axis in the plane of the implant, which will determine the orientation of the implant body. When the implant is in adverse conditions attaching crowns may be difficult or impossible because of too strong inclination.
Dynamic and static spaces for crown restore
It is important to make sure that there is enough space for the suprastructure in the mouth; sometimes it is necessary to make diagnostic models, especially for assessing the impact of jaw movements on the amount of space for the suprastructure.
Prediction for remaining teeth
Assessment of the remaining teeth is very important, since modern implants can operate successfully throughout the patient's life. Implant set to produce one form of the prosthesis can be completely unsuitable for other prosthetic construction in the subsequent loss of teeth.
Condition of existing dentures
Evaluation of existing dentures condition allows you to set the likelihood of solving the problem with a new prosthesis, materiality patient complaints and the possibility of successful treatment with implants.
