Implantation

A dental implant is an artificial root that is embedded into the bone, usually made of titanium, used in dentistry for supporting one or more tooth replacements.

All dental implants in use today are the type endoseal root implants, ie. they are very similar to real root of the tooth, imitate the authentic root form and are embbed into the bone. The jawbone merges with the titanium implant and giving place to osseointegration process. Bone integration refers to the connection of the implant surface with the surrounding bone. Dental implants then interface with the bones. Dental implants are used to support a number of dental restorations, including crowns, bridges or dentures on implants. They can also be used as a support for orthodontic tooth movement. The use of dental implants enables unidirectional tooth movement without retroactive effect.

Implants are the best and most convenient solution for tooth loss. They represent the optimal solution for therapeutic, medical as well as for aesthetic purposes.

Implants give patients a feeling of natural teeth, look natural and fit in well with the remaining teeth in the jaw.

We use implants made of titanium, a material human body readily accepts, and they are surgically embedded into the jaw in place of the missing tooth. After a certain period of time, a superstructure is set on the implant to hold crowns and bridges. Dental implants are the size of a natural tooth root and thus ensure a natural and safe feeling when speaking and eating.

Implants achieve the best combination of functionality and aesthetics of the tooth.
We use the most advanced type of implants, Nobel Biocare, Straumann and OSST. These interventions are performed by well-known and recognized experts in the field.

All surgical interventions are painless for the patient.

Surgery planning

Before surgery detailed and careful planning is necessary in order to determine the vital structures such as the lower alveolar nerve or sinus and the shape and dimensions of the bone so that the implant can be properly oriented so as to provide the best result. It is customary that before the surgery two-dimensional radiographic images such as orthopantomograph or retroalveolar images are made. In some cases, CT scan (Computed Tomography) is also recommended. For treatment planning it is necessary to use specialized 3D CAD / CAM computer program.

 

Basic procedure

Basically an implant requires bone preparation by using manual osteotomes or precision borers at a highly controlled rate (fisiodispenser) in order to prevent bone overheating and necrosis due to excessive pressure. After a certain period of time, which will allow the bone to integrate with the surface of the implant (osseointegration), crows or bridges can be placed on implant. Unlike conventional dental implants, mini dental implants can be inserted immediately, and thereby will maintain a high level of acceptance (94%). The time required for an implant placement depends on the experience of the surgeon, the quality and quantity of the bone and the specifics of each particular case.

To make sure the process of placing dental implant is successful, there must be enough bone in the jaw, and the bone has to be strong enough to withstand the implant. If there is not enough bone, it must be added. This process is called bone augmentation, or guided bone regeneration. Mini dental implants are especially useful in edentulous jaws with a minimal amount of bone in the anteroposterior direction. In addition, natural teeth and surrounding tissue around the implants must be healthy.

In all cases special attention must be paid to the final functional characteristics of restoration, such as assessing all the forces which will imapct the implant. The pressure on the mplant caused by chewing and parafunctions (bruxism, ie. teeth grinding or clenching) may exceed the biomechanical tolerance of thr bone surface and / or titanium and thus cause a failed surgery. This can consist in damage to the implant or in bone loss, "melting" or nearby bone resorption.

The dentist must first decide what kind of restoration is required. Only then can he determine the specific requirements of the implant - the number, length, diameter and thread type. In other words, before the procedure the teeth and jaws need to be healthy. If the volume or density is inadequate the dentist must first consider the process of adding bone. He can consult with relevant specialists such as oral surgeon, paradonthologist, endodontist or other specialists for joint treatment of the patient. Typically, models or impressions of the jaw and teeth taken by the prosthetist at the request of the surgeon are used as an aid in treatment planning. If he doesn’t have the imprints of the teeth and the jaw, the surgeon makes his own or relies upon advanced computer tomography or CT scan with conical rays, to be able to plan appropriate treatement.
