Abstract:
The first aim of this study is to compare the outcomes in rehabilitating the atrophic maxilla using zygomatic implants ( ZIs ) and regular implants ( RIs ) using the classical zygomatic technique ( CZT ) versus the zygomatic anatomy‐guided approach ( ZAGA ). The second goal of this paper is to propose a standardized system to report rhinosinusitis diagnosis. Materials and Methods Twenty‐two consecutive zygomatic patients operated on from 1998 to 2002 and 80 consecutive zygomatic patients operated on from 2004 to O ctober 2009 were selected. All included patients were in a maintenance program. Survival rates ( SRs ) of ZI and RI were recorded. Implants were individually tested using P eriotest® ( P eriotest value [ PTv ], S iemens AG , B ensheim, UK ). Sinus health was radiographically and clinically assessed according to L und‐ M ackay system and L anza and K ennedy survey recommended by T ask F orce on R hinosinusitis for research outcomes. A satisfaction questionnaire (Oral Health Impact Profile for assessing health‐related quality of life in Edentulous adults) and different anatomical measurements were also performed. Results No significant differences ( p = .602) were observed with respect to SR between the two groups (95.12% vs 96.79%). Significant differences ( p = .000) were found comparing measurements of ZI head distance to the alveolar crest (5.12 ± 2.38 mm vs 2.92 ± 2.30 mm). With the CZT , more palatal emergence of ZI was observed. PTv gave significantly greater stability for the CZT compared with the ZAGA group in both measurements (−4.38 ± 1.75 vs −2.49 ± 4.31, p = .000; −4.94 ± 1.46 vs −3.11 ± 5.06, p = .000). L und‐ M ackay score was significantly lower for the ZAGA group (2.38 ± 3.86 vs 0.56 ± 1.26, p = .042). Statistically significant difference ( p = .047) regarding the percentage of patients with no signs or symptoms of rhinosinusitis ( L anza and K ennedy test negative and L und‐ M ackay score zero) was observed between groups (54.55% vs 76.25%, p = .047). Conclusions Both procedures had similar clinical outcomes with respect to implant survival. The ZAGA concept is able to immediately rehabilitate the severely atrophic maxillae, minimizing the risk of maxillary sinus‐associated pathology. Moreover, less bulky, more comfortable, and easy to clean prostheses are achieved.
