The purpose of this article is to present a minimally invasive technique using the implant drills to help extract teeth before the insertion of immediate implants.
Nine patients (7 women and 2 men) aged 24 to 60 years having root fractures and dental caries were included in this study. Inclusion criteria for the study were presence of at least 4 mm of bone beyond the root apex, the absence of acute signs of infection or inflammation in the treatment area, and the absence of systemic pathologies that would contraindicate bone healing around implants. Heavy smokers were not included in the study. Extraction was done after thinning the root walls by the help of the implant drills. After extraction, implant sites were prepared and implants were inserted. In 2 of the cases, the peri-implant bone defect was filled with autogenous bone graft.
Healing progressed uneventfully in all 9 cases. The use of implant drills to thin the root walls provided atraumatic tooth extraction protecting the thin buccal bone. At second stage surgery, all implants were asymptomatic, immobile, and osseointegrated. The soft tissue anatomy was clinically acceptable in all patients. Radiographic examination of all 9 implants showed no peri-implant radiolucency at the end of a year.
Successful osseointegration and complete bone healing were observed for all patients. The new extraction technique was found to be effective in immediate implant cases in order not to damage the thin plate of buccal bone.
本文旨在介绍一种微创技术，使用种植体钻头帮助在植入即刻种植体之前拔牙。
本研究纳入了 9 名年龄在 24 至 60 岁之间的患者（7 名女性和 2 名男性），他们均有牙根折断和龋齿。该研究的纳入标准为：根尖端至少有 4 毫米的骨量，治疗区域无急性感染或炎症迹象，且无会影响种植体周围骨愈合的系统性疾病。重度吸烟者不包括在研究中。通过种植体钻头帮助薄化牙根壁后进行拔牙。拔牙后，准备种植部位并植入种植体。在 2 例病例中，使用自体骨移植填充了种植体周围骨缺损。
所有 9 例患者的愈合均顺利进行。使用种植体钻头薄化牙根壁可在保护薄的颊侧骨的同时进行无创伤拔牙。二期手术时，所有种植体均无症状、无动度且骨整合良好。所有患者的软组织解剖均在临床可接受范围内。所有 9 个种植体的放射学检查在一年后均未见种植体周围放射透光区。
所有患者均观察到成功的骨整合和完全骨愈合。这种新的拔牙技术在即刻种植病例中被发现是有效的，可避免损伤颊侧薄骨板。
