“…Hinze et al [24] with Chow's technique described an increase in peri-implant bone around the coronal part of the implant (buccal bone 1.4 ± 0.5 mm and palatal bone 4.3 ± 0.4 mm) at 6 months. The results of this study showed similar bone gained width (buccal bone 2.65 mm and palatal bone 3 mm) at 6 months.…”

“…Bone gain was measured in the CBCT images at 6 months in two directions: through a perpendicular buccal and palatal lines to the implant axis (width) [24] and through a parallel buccal and palatal lines to the implant axis at level of coronal part of the implant (length) (Figure 4). Keratinized buccal mucosa width was measured at 3 months in cases with immediate loading and at the removal of second-surgery suture in cases without immediate loading (< or > 2 mm of keratinized buccal mucosa width).…”

“…A number of techniques for bone and soft tissue enhancement around zygomatic implants have been described, with high success rates. Regarding bone regeneration, a sinus lift during the zygomatic implant placement has been proposed [23,24]. Regarding soft tissue enhancement, dissection of the buccal fat pad [25] and the ZAGA "Scarf Graft" (pediculate connective tissue grafting [26]) have been utilized to prevent buccal mucosal recession.…”

Purpose: To present a case series of zygomatic implants combined with bone regeneration and soft tissue enhancement techniques to reduce the risk of biological delayed complications such as maxillary sinusitis and soft tissue recession. Materials and methods: Zygomatic implants placed simultaneously with different bone regeneration techniques (buccal, palatal and buccal-palatal bone regeneration) and soft tissue enhancement techniques (pediculate and free connective tissue graft) were followed for at least 12 months. The following information was collected: patient age and sex, number of zygomatic implants, zygomatic implant success rate, zygomatic implant position according to classification of the Zygomatic Anatomy Guide Approach (ZAGA), sinus membrane perforation, type and outcome of the bone regeneration or the soft tissue enhancement technique, bone gain (width and length along the zygomatic implant) and keratinized buccal mucosa width, duration of follow-up, loading protocol (immediate or delayed) and biological complications (maxillary sinusitis and soft tissue recession). Results: Thirty-one zygomatic implants placed in 19 patients were included. All implants were successful and none of the implants presented biological complications. The bone regeneration technique was successful in 30 of 31 cases with a mean palatal bone width of 3 mm, buccal bone width of 2.65 mm, palatal bone length of 6.5 mm and buccal bone length of 8.3 mm. The success rate of soft tissue enhancement was 100% and it established at least 2 mm of keratinized buccal mucosa width in all implants. Conclusions: Within the limitations of the present study, bone regeneration and soft tissue enhancement techniques were useful to establish more favorable conditions of the peri-implant tissues around zygomatic implants. This could prevent biological complications such as maxillary sinusitis and soft tissue recessions. Prospective and randomized controlled clinical trials with longer follow-up periods are advisable.

“…Early publications on zygomatic implants were presented as case reports (28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38). By considering our large case series, it became evident that the reconstruction of an atrophic jaw with zygomatic implants provide a good fine prosthetic solution while reduce the disadvantages related to a major surgery.…”

SUMMARYTreatment of severe maxillary atrophy with implants has achieved important successes in recent years. The limit of implant insertion is related to inadequate bone quantity (i.e. height and width). Alveolar bone grafting, sinus lifting and major grafting via Le Fort I osteotomy have used in the past to restore bone volume prior of implant insertion. However successes do not always occur and a second stage surgery is necessary in most cases. Immediate loading cannot be performed in all grafted bone. In recent years a new treatment approach has been proposed by using zygomatic implants. This new technique can provide a better stability to the prosthesis and less morbidity for patient. Here a cases series of eighteen patients rehabilitated with zygomatic together with standard implants and immediate loading is reported.

“…Furthermore, the visually controlled implant placement facilitates easier and more reproducible implant positioning, enabling prosthetically ideal orientation of the implant platform. 8 Step 1: Crestal incision, elevation of a mucoperiosteal flap, and visualization of the lateral antral wall.…”

Zygomatic Implants: A Boon For The Depleted Maxilla

ABSTRACT:Rehabilitation of the severely resorbed maxilla poses a dificult challenge for the clinician with inadequate stability with the use of removable dentures which also accelerate the resorption pattern as well. Placement of dental implants in the posterior maxilla is often jeopardized by the size and extension of the sinus cavities and inadequate amounts of bone. The next automatic choice for the rehabilitation turns out to be the placement of implants in the zygomatic bone with the help of Autogenous bone, harvested from the iliac crest. This article gives a review of the rehabilitation of severely resorbed maxilla with the placement of zygomatic implants and its advantages and disadvantages.
