A new dental implant system was used to replace the mandibular right first molar tooth in an eleven-month-old male/intact, utility trained German shepherd dog. The permanent mandibular right first molar tooth had been extracted as treatment for an extensive carious lesion when the dog was 9-months of age. There were no complications associated with placement of the dental implant. However, peri-implant osteomyelitis occurred secondary to a traumatic oral wound 6-months following implant placement. The 17-month post-operative examination indicated that the implant system used in this case could be maintained in a working dog that uses extreme bite forces. However, periodontal inflammation and vertical bone loss exposing the implant fixtures were noted during oral examination. Further clinical applications are required to determine if the periodontal inflammation and vertical bone loss noted in this case were complications associated with the implant, maturity of bone at the time of implant fixture placement, general biting/chewing forces placed on carnassial teeth, or the oral trauma that occurred 6-months following implant placement.
一种新型牙种植体系统被用于替换一只11个月大、未绝育、经过实用技能训练的雄性德国牧羊犬右下第一恒磨牙。这只狗9个月大时，右下第一恒磨牙因广泛龋损被拔除作为治疗手段。牙种植体植入过程未出现并发症。然而，种植体植入6个月后，因口腔创伤继发了种植体周围骨髓炎。术后17个月的检查表明，该病例使用的种植体系统在一只使用极大咬合力的工作犬体内能够维持。不过，口腔检查时发现了牙周炎症以及暴露种植体固定装置的垂直骨吸收。需要进一步的临床应用来确定本病例中观察到的牙周炎症和垂直骨吸收是与种植体相关的并发症、种植体固定装置植入时骨的成熟度、施加于裂齿的一般咬合力/咀嚼力，还是种植体植入6个月后发生的口腔创伤有关。
