A new approach to rehabilitate the severely atrophic maxilla using extramaxillary anchored implants in immediate function: A pilot study

Multiple Zygomatic Implants as an Alternative for Rehabilitation of the Extremely Atrophic Maxilla: A Case Letter With 55 Months of Follow-Up

“…3,19,20 Favorable clinical findings were also observed with the use of 4 zygomatic fixtures, where 2 implants were placed in the each zygomatic bone. 1,[11][12][13][14][15][16] Therefore, the success of multiple zygomatic implants reported in this case is in accordance with the high success rates previously described. 2,3,7,8 Torque values greater than 40 N.cm were obtained during implant placement, allowing the application of immediate loading technique.…”

“…The zygomatic bone density permits the use of immediate prosthetic loading. 12,14,22 Indeed, the success of this rehabilitation technique is related to the biomechanical concepts. Tilted implants may create horizontal forces when subjected to load therefore, being the most critical aspect of zygomatic implants.…”

Rehabilitation of totally atrophied maxilla by means of four zygomatic implants and fixed prosthesis: a 6–40-month follow-up

“…In these cases, treatment is the administration of antibiotics and/or meatotomies and repositioning the soft tissue without the removal of the stable zygomatic implant. No recurrence of sinusitis was seen 7,15,17 . The reason for the sinusitis could be perforation of the sinus membrane, leakage at the level of the maxilla due to a hole in the zygomatic implant leading to migration of bacteria from the mouth to the sinus.…”

“…Few studies 10,17 have been published concerning a consecutive series of totally edentulous patients with four zygomatic implants. A technical note proposed three zygomatic implants in a dry skull 5 showing the amount of bone available in the zygoma region.…”

“…The incidence is 14-30%. In some cases, patients with an oro-antral fistula may develop suppuration with or without sinusitis 3,7,15,17 . In these cases, treatment is the administration of antibiotics and/or meatotomies and repositioning the soft tissue without the removal of the stable zygomatic implant.…”
