The conventional osseointegration protocol calls for waiting up to 12 months for ossification of an extraction socket to heal before placing an endosseous implant. In this study the possibility of placing a pure titanium implant directly into an extraction socket immediately after extraction was investigated. A pure titanium Nobelpharma 10-mm implant was placed into a central incisor extraction socket of a stump-tailed monkey and allowed to heal for a period of 6 months, followed by functional loading of the implant. The implant was osseointegrated on a clinical and histological level. This pilot study suggests that pure titanium implants have the potential to integrate when placed immediately after extraction of the teeth and warrants further investigation.
传统的骨结合方案要求在拔牙窝骨化愈合长达12个月后再植入骨内种植体。在本研究中，研究了拔牙后立即将纯钛种植体直接植入拔牙窝的可能性。将一枚10毫米的纯钛诺贝尔pharma种植体植入一只短尾猴的中切牙拔牙窝，使其愈合6个月，然后对种植体进行功能性加载。该种植体在临床和组织学水平上实现了骨结合。这项初步研究表明，纯钛种植体在拔牙后立即植入时有实现骨结合的潜力，值得进一步研究。
