METZi minimal exposure technoique for zygomatic implants - minimal exposure maximum impact
Abstract Summary:
The Minimal exposure technique (MET), is the latest technique for zygomatic implant placement in patients who are severely deficient in the upper jaw bone due to bone loss. A graft-free method, reduces the risk of paresthesia and surgical trauma, simultaneously ensuring successful implant integration with bone. The technique of zygomatic implants aims at providing minimal invasion of the maxilla yet a sound rehabilitation in cases where severe bone loss is seen with improved comfort and minimal complications as the priority. This technique includes detailed pre-surgical planning to figure out the favorable implant positions. The surgery is performed by preparing zygomatic bone carefully with vestibular incision, followed by precise implant placement without much tissue invasion. METZI has yielded results such as better implant stability and is graft-free. Using a vestibular incision decreases the risk of complications like paresthesia, hematoma, oroantral communication, mucositis, and peri-implantitis. It was concluded that METZI is a safe and impactful method for rehabilitation of maxilla, reducing the complications and, better patient outcomes.
Background and Objectives:
The flapless zygomatic implants have changed the missing teeth rehabilitation for atrophic maxilla by introducing a grafless and minimally invasive as an alternative. This technique, unlike the conventional implant methods, does not need extensive grafting and anchors the implants in zygomatic bone, providing stability in even severe bone loss cases. In comparison to longer treatment time cases like sinus augmentation, short or tilted implants zygomatic implants, zygomatic implants offer a better solution for missing teeth rehabilitation where the bone is atrophic in the maxilla.
These challenges were addressed by the MET-ZI method, which enhances visibility while decreasing tissue trauma. By engaging in the vestibular incision, MET-ZI ensures precise implant placement and decreases postoperative complications such as numbness, bruising, inflammation, sinus communication, implant exposure, and infections. The researchers have suggested the possible links of post-zygomatic implant paresthesia to infraorbital and zygomaticofacial nerve damage [2,3,4], with studies reporting incidences of 5.4 % (Besdrosdian) and 4.6% (Aparicio et al.) [5,6]. MET-ZI’s minimally invasive nature significantly lowers these risks.
Key Takeaway Points:
1. novel technique for zygomatic implant placement minimum trauma decreased downtime.
