Zygoma implant‐supported midfacial prosthetic rehabilitation: a 4‐year follow‐up study including assessment of quality of life

Abstract

Zygoma implants can reliably anchor the midfacial maxillary prostheses and enable a quality of life comparable with autologous maxillary reconstruction. They can be replaced immediately if local infection or loosening should occur. A premolar and canine position reduce leverage when no anterior alveolar process is present. The patient can alternatively be provided with dental implants.

Zygoma implant-supported prosthetic rehabilitation after partial maxillectomy using surgical navigation: A clinical report

“…Recent investigations have confirmed the effectiveness of obturator prostheses in terms of speech, masticatory function, swallowing and appearance, 5,28 especially for small defects. 6,12 There is evidence that speech can be restored to a preoperative level with a maxillary obturator prosthesis.…”

“…36 Since then several reports have been published on the clinical performance of zygoma implants. 28,29,31,35,[37][38][39][40][41][42][43][44][45][46] The 2 primary indications for the use of zygoma implants are atrophic edentulous maxillae and defects after maxillary resection. 28,29,40 Zygoma implants are generally placed at a 30 to 60-degree angle relative to the occlusal plane.…”

“…28,35,40,47 This clinical report demonstrates the use of a zygoma implant to improve stability and retention of a telescopic-crown retained [48][49][50][51] obturator prosthesis and highlights the benefits of computer-supported navigation when placing such an implant.…”

“…[24][25][26][27] Because of the limited amount of remaining maxillary bone following maxillectomy, implant placement for anchoring a prosthesis has also been performed in more remote sites such as the zygomatic bone. [28][29][30][31][32][33][34][35] The zygoma implant (Zygomaticus fixture; Nobel Biocare, Göteborg, Sweden) developed by Branemark was specifically designed to offer maximum bone anchorage while simplifying access to the implant head, facilitating the abutment connection. 36 The zygoma implant is available in 8 lengths ranging from 30 to 52.5 mm.…”

Zygomatic implant: Late complications in a period of 12 years of experience

“…Some examples of late complication are: loss of fixation or osseointegration, bucco sinusal communication, fenestration of the buccal mucosa, chronic sinusitis and sinus pathologies, palatal emergency of fixations, mucositis and peri-implantitis. (6)(7)(8)(9)(10)(11)(12)(13)(14) Recent systematic review studies reported the survival and presence of complications related of zygomatic fixation. (15) They conclude that the studies with a high level of evidence are scarce.…”
