This study was performed to evaluate the feasibility of using preoperative surgical simulation to enhance the clinical outcome in patients undergoing bi\u2010directional alveolar distraction osteogenesis.<\/jats:p><jats:p><jats:bold>Material and methods: <\/jats:bold> Nine patients (mean age, 49 years; range, 20\u201361 years) with maxillary segmental alveolar defects following post\u2010traumatic atrophy or disuse atrophy after periodontal tooth loss were enrolled in the study. All patients were scheduled for implant placement. Three\u2010dimensional (3\u2010D) morphological evaluation and virtual bi\u2010directional distraction were performed with SimPlant CMF\/OMS surgical simulation software (Materialise). In addition, use of an extraosseous bi\u2010directional distraction device (V2\u2010Alveolar Distraction System; Medartis AG) was evaluated during the 3\u2010D alveolar regeneration simulation and resulting augmentation.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> Alveolar height regeneration and labial\u2010buccal augmentation were planned preoperatively using surgical simulation software. New bone formation with sufficient vertical augmentation of 5.8\u2003mm was observed. As we encountered strong palatal inclination, the angulation required for labial\u2010buccal augmentation during active distraction was the maximum angulation of 40\u00b0, even greater than that required in the preoperative simulation of 23.9\u00b0. Furthermore, the labial\u2010buccal augmented angulation was gradually decreased to 11.2\u00b0 at the time of implant placement. In all cases, implantation was successful at the well\u2010augmented sites, with sufficient primary stability after a 3\u2010month consolidation period.<\/jats:p><jats:p><jats:bold>Conclusions: <\/jats:bold> Preoperative 3\u2010D simulation is a potentially valuable tool for treatment of the morphologically complicated oral\u2010maxillofacial region. More realistic surgical simulations are anticipated with ongoing effort to collect and integrate clinical data into next\u2010generation software.<\/jats:p>","DOI":"10.1111\/j.1600-0501.2008.01579.x","type":"journal-article","created":{"date-parts":[[2008,10,8]],"date-time":"2008-10-08T19:20:23Z","timestamp":1223493623000},"page":"1211-1218","source":"Crossref","is-referenced-by-count":13,"title":["Computer\u2010simulated bi\u2010directional alveolar distraction osteogenesis"],"prefix":"10.1111","volume":"19","author":[{"given":"Takahiro","family":"Kanno","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaharu","family":"Mitsugi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shintaro","family":"Sukegawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michi","family":"Hosoe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshihiko","family":"Furuki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,11,11]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"11","article-title":"The long\u2010term efficacy of currently used dental implants","volume":"1","author":"Albrektsson T.","year":"1986","journal-title":"The International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.id.0000226824.39526.71"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1997.080302.x"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2007.01.024"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2005.01196.x"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2005.01247.x"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2004.00999.x"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2007.01351.x"},{"key":"e_1_2_5_10_1","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1016\/S1061-3315(18)30059-3","article-title":"Distraction osteogenesis for dental implants","volume":"7","author":"Chin M.","year":"1999","journal-title":"Atlas of the Oral and Maxillofacial Surgery Clinics of North America"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2006.01.021"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tripleo.2004.11.021"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1053\/joms.2002.31844"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2006.04.001"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1054\/jcms.2000.0203"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/PL00014524"},{"key":"e_1_2_5_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjoms.2005.05.021"},{"key":"e_1_2_5_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2005.01185.x"},{"key":"e_1_2_5_19_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199001000-00003"},{"key":"e_1_2_5_20_1","first-page":"52","article-title":"Anterior maxillary alveolar distraction osteogenesis","volume":"17","author":"Jensen O.T.","year":"2002","journal-title":"The International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_5_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2006.11.009"},{"key":"e_1_2_5_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0915-6992(06)80018-X"},{"key":"e_1_2_5_23_1","first-page":"446","article-title":"A comparison of jaw dimensional and quality assessments of bone characteristics with cone\u2010beam ct, spiral tomography, and multi\u2010slice spiral ct","volume":"22","author":"Loubele M.","year":"2007","journal-title":"The International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_5_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2005.08.016"},{"key":"e_1_2_5_25_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2007.060048"},{"key":"e_1_2_5_26_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcms.2006.12.004"},{"key":"e_1_2_5_27_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2005.10.015"},{"key":"e_1_2_5_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2005.12.080"},{"key":"e_1_2_5_29_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joms.2004.06.039"},{"key":"e_1_2_5_30_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.2002.130203.x"},{"key":"e_1_2_5_31_1","first-page":"215","article-title":"Prosthetically directed implant placement using computer software to ensure precise placement and predictable prosthetic outcomes.
