It is not possible to use any implant brand for guided closed surgery. Only some implant brands offer special drill sets and special sleeves for plaque preparation that are specific to guided closed surgeries. You can contact us for detailed information about these implant brands.
After planning, the digital data is transferred to special CAD / CAM systems to fabricate the surgical guide template. This template is a transparent plastic plaque which guides the surgeon to position the implants with precision. Special sleeves that guide the drills to open implant holes, are located on that template. Finally the template is being disinfected to be ready for surgical operation.
After guided implant surgery, the patient may have fixed prosthesis on the same day of implant placement procedure. As there are no sutures and minimum swelling, the prosthesis measures are taken more accurately.
In standard implant treatment, first the implants are placed and then the prosthesis measures are taken to manufacture the prosthesis. However with guided implant procedures, the prosthesis is planned at the beginning of the procedure and the implants are placed to the points that are best for the prosthesis. Thus, more aesthetic, stable and functional prostheses can be made.
If the patient has removable denture, barium sulfate is put into that denture to get the implant template. With this method, the distance between the gum and the bone can be measured more precisely. Another method is that, the surgeon places 2 or 3 mini implants within the jawbone of the patient by using minimum anesthesia and takes a 3-D image of patient’s mouth. The aim of this method is to make sure that the planned surgical guide fits patient’s mouth with precision.
• Surgery time is reduced to one third or even one fourth compared to classic approach.
• Implant positioning can be much more accurate. This has a positive effect on the long-term success of the dental implant.
• In some cases where advanced surgery is required, the implant can be placed without the need for further internevtions.
• Post-surgery bleedings, pain, swellings are seen much less and for a shorter time and no stitches needed.
• Recovery time is much faster.
• It is possible to produce more aesthetic and functional prostheses.
• Cannot be performed for patients who don't have sufficient bone volume and quality.
• It is a little more costly than classical surgery.
• If the treatment has planed badly or the surgery is not performed in accordance with the planning, wanted results cannot be obtained with the closed surgery and the procedures can be continued with the open approach. Dentist's experience and skill in field is extremely important.
Standard panoramic x-ray images are not sufficient for guided surgery. Because those will only give 2D images and will show only the height and width of the bone but not the diameter and depth. The feasibility of the implant and the most suitable place and angle may not be determined through two-dimensional images. In addition, the most accurate evaluation for the diameter and length of the implant to be placed can be obtained with three-dimensional imaging systems. So, 3D imaging systems are a very important tool in determining where and how the implant can best be placed without opening the gingiva.
Before surgery, the patient's intraoral 3D image is taken. Afterwards, the surgeon analyzes patient's teeth and jaw structure in the "surgical guide" preparation program on the computer. S/he plans where and at which angles and in which dimensions implants will be made based on this analysis results.
Not every implant brand can be placed with the guided surgery method. For guided surgery, some implant brands have special drill sets for their implants and "sleves" for preparing plaques. You can consult us to get information about the brands that produce solutions in this field.
The digital data generated after the implant planning is transferred to special CadCam systems and a surgical guide is created through these systems without human intervention. This guide is a plate consisting of a transparent plastic that will show how the physician who will perform the implant surgery will place the implants in which areas. “Sleves” that guide the burs used to open the implant slots are attached to the plate made of transparent plastic. Afterwards, this plate is disinfected and prepared for the surgical procedure.
If the patient has removable dentures, barium sulphate is applied to the existing dentures and x-ray is taken in that way. In this way, the distance between the bone and the gum can be determined more clearly. As the second method, 2 or 3 mini implants can placed in the patient's jawbone with small anesthesia and a 3-D image of the jaw is taken. It is the stable fit of the surgical guide produced as a result of target planning in the patient's mouth.
The guide has been digitally prepared to be placed in the mouth. Small slots will be opened in the patient's mouth in accordance with the directions in the surgical guide where only the implants can enter, without bringing deep cuts with a scalpel. The 3-D image of the patient's chin is taken again to check whether everything is going according to plan if necessary. Bone abrasions are made by means of bursn order to place the implants through these holes. Then the implants will be placed. As a final step, gingival shapers are placed in the area where the implant is placed. The purpose of this is to shape the gums for the prosthesis to be made later and to prevent the gums from closing there. After this surgery, there is no need for stitches to the gums. For this reason, it is also called sutureless surgery.
One of the most important advantages of guided surgery over classical implant surgery is in prosthesis field. In classic method, implants are placed, then the impression is taken. The prosthesis is planned in the first stage when it comes to guided surgery and the implants are tried to be placed in the most suitable places for the prosthesis. In this way, more aesthetic, more stable and more functional prostheses can be obtained.
Other than that the prosthesis stages are the same as the prosthesis stages in classical surgery.
