In the planning phase of the OCTO implant, patient’s findings obtained by means of a model, clinical and radiographic examinations are assesed according to the patient’s force factors. These findings should be planned by the dentist for each case specifically to obtain optimum loading conditions. In order to reduce the complication risk and increase the prosthetic success it is recommended to apply the implants by means of the surgical stent. OCTO implants can be applied by means of the surgical technique without raising a flap (flapless surgery). The dentists preforming this method should have sufficient experience and they should try to insert the implants against to palatinal cortical plate to protect the buccal osteotomy plate.
Preparations before surgery
For a successful treatment outcome, implants should be applied pursuant to general health and dentistry rules with a carefull planning in the direction of the following procedures.
- The oral situation of the patient should be assessed carefully with clinical examination, radiography and diagnostic model.
- If different treatment alternatives are in question, the consent of the patient should be confirmed after the negative and positive aspects of each method and the treatment duration are explained sufficiently.
- Anamnesis from the patient should be taken to assess the general status of the patient. If there is any suspicion, the preparations for the implant surgery treatment should be initiated in case that it is understood that there is no problem after the necessary examinations are performed.
- Only unbroken seal of the plastic cap of the implant box can maintain the sterilization conditions ensured by the gamma radiation. Therefore, it should be carefully controlled whether the packages are not open.
- The products which are not completely closed and/or those with disrupted packages cannot be used. The physician should examine whether there is any foreign body or any contamination on
Alternatives in Prosthetic Planning in Surgery
By using 10°, 17° and 25° angled abutments, the parallelism of the OCTO abutments can be obtained in the mouth, therefore, the fixed restorations can be done with direct technique within the mouth, in such case, laboratory transfer using analogs is not needed. In order to protect the bone and the soft tissue, it is recommended to insert abutments during the surgery and to apply the conventional stages of the crown and bridge restoration procedure. At this stage, a temporary restoration should be made to form the natural gingival contours and the crown emerging profile.
Temporary restorations
Temporary crown and bridge restorations can be made by means of the following methods:
- By using standard prefabricated crowns.
- By using an impression taken from a current restoration or from a setup model.
- By using acrylic shell temporaries prepared in the laboratory. Although, temporary restoration can be made by selecting any of the method above, the parallelism of the abutments within the mouth can be obtained without transferring the implant positions to the laboratory by virtue of 10°, 17° and 25° angled OCTO abutments that can rotate 3600. Therefore, initially obtained parallel abutments can give the option of preparing the temporary restoration within the mouth which provides the advantage of less clinical working time to the physician.
