Radioanatomical characteristics of zygoma for planning of quad zygoma implants: a cross sectional study.
Purpose: To evaluate the radioanatomical measurements of the zygoma as a guide for treatment planning of quad zygomatic implant placement.
Methods: This cross sectional study was carried on 17 patients of 34 zygomatic regions reported with atrophic maxilla for placement of zygomatic implants. The zygomatic implants were placed virtually in a quad approach using "Real Guide" version 3.0" and, the following parameters were assessed at 20 points in antero- superior, antero-inferior, postero-superior and postero-inferior regions. The thickness of zygomatic bone, Installation angle of zygomatic implants, Length of the installed zygomatic implants and Distance between the zygomatic implants on each side were measured using Cone Beam Computed Tomography (CBCT) on a virtual planning software "Materialise Mimics" version 15.
Results: The mesial implant can be emerged in antero-superior region and the distal implant can be emerged in antero-inferior region on the right side zygoma since the maximum thickness of zygomatic bone was seen in D2, A1, A3 and D4 directions. Similarly in the left side of zygoma, the mesial implant can emerge in postero-superior region and distal implant can be emerge in postero-inferior region since the maximum thickness was seen in D2 and A3 directions (P > 0.05). The installation angle for mesial implant in right and left side was 450 and the distal implant angle for right and left side was 450 and 460 (P < 0.05). The mesial zygomatic implant length for right and left side was 55.88 mm and 56.18 mm while, the distal zygomatic implant length for right and left side was 44.56 mm and 45.59 mm (P > 0.05). The distance between the two zygomatic implants in right and left side was 5.06 mm and 4.54 mm (P > 0.05).
Conclusion: Virtual planning for placement of implants in quad zygoma approach would be a feasible requirement as it eases out the surgeon's practice and prevents the possibilities of causing intrusion complications intraoperatively. Hence, quad zygoma implants remains a promising viable option for patients presenting with severe atrophic maxilla.
期刊介绍：
Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
