A UNIQUE APPLICATION
Some patients have medical problems that prohibit them from benefiting from conventional upper arch dental implants. The major issue is a lack of adequate quality and/or quantity of alveolar bone (the jawbone where the teeth are situated) in the upper jaw, where conventional implants are often put.
Technological advancements have resulted in the development of zygomatic implants, a novel form of dental implant for the maxilla (upper jaw). They are termed zygomatic implants because they are placed into the zygomatic bone; humans have two zygomatic bones, one on each side of the maxilla, adjacent to the sinuses near the nose. These bones are easily identified on a face since they are responsible for the look of the cheekbones.
The primary restriction of zygomatic implants is, predictably, that they can only be utilized in the upper jaw because there is no zygomatic bone next to the mandible. In the event of lower alveolar bone atrophy, another treatment strategy for the lower dentition must be offered to the patient.
ZYGOMATIC IMPLANTS INSTALLATION
Because they are placed into bones higher than the maxilla, zygomatic implants are much longer than ordinary implants.
The use of zygomatic implants is frequently coupled with the placement of conventional implants in the jawbone to increase the stability of the denture in the mouth. Two zygomatic implants and two to four conventional implants are often required to complete the framework required for denture installation.
Four zygomatic implants can be utilized in instances when bone loss is severe; no standard implant is required in this scenario.
A NEW TECHNOLOGY
Zygomatic implants are very new, having been used on a patient for the first time in 1989.
Professor Per Ingvar Brnemark created them after conducting several tests on the skull bones to identify the best alternative to implants put in the jawbone.
ZYGOMATIC IMPLANTS ADVANTAGES
- Even if there is substantial bone atrophy in the upper jaw owing to lost teeth, this kind of implant does not require bone grafting or sinus augmentation.
- If the zygomatic implants are put appropriately, directly close to the maxillary sinuses, by a specialist with adequate expertise for this type of implant, the potential problems in the maxillary sinuses, as in the case of conventional implants, are practically non-existent.
- In the case of zygomatic implants, the prosthesis that restores masticatory function and enhances face aesthetics can be implanted right away.
- The insertion of the implants is computer-assisted, allowing the surgeon to design and practice the surgery ahead of time. As a result, the outcomes are somewhat predictable.
- The healing time is faster than with other types of implants, reducing the overall treatment time.
- The surgery’s success rate is comparable to or higher than that of traditional implants or mini-implants (over 95 percent).
ZYGOMATIC IMPLANTS’ DISADVANTAGES
- The prosthesis that is put on the zygomatic implants must occasionally have a portion that sits on the patient’s palate, reducing his comfort and phonetics quality, among other things.
- There should be no indications of disease or symptoms in the maxillary sinuses.
