视频展示了通过插入C-Tech Implant的四个直径为2.1毫米、高度为13毫米的口内迷你植体来稳定下颌活动义齿的关键步骤。在此之前，为患者制作了上颌和下颌全口义齿，按照最高的精度和质量标准执行。
为准备手术，我们要求牙科技师使用透明树脂复制废弃的下颌义齿。这个复制品经过修改，在犬齿远端添加了两个金属标记，以便在手术过程中定位。手术前，患者口中含有复制品进行了全景X光检查。这张放射影像使我们能够精确确定标记与颏孔的距离，从而划定了一个安全且明确的工作区域。
在手术阶段，我们使用复制品进行骨切开术，从远端开始，然后进行中央部分。利用C-Tech迷你植体的先进特性，垂直和水平方向的准备工作至关重要。这些植体具有主动尖端，使其自我定位和自我钻孔，便于插入并提高初始稳定性。
植体的插入分多个阶段进行：最初的旋转使用特氟龙载体，然后使用蝴蝶螺丝刀进行后续旋转。最后的旋转再次使用载体和扭矩扳手，以验证达到30 Ncm，这是立即加载义齿的必要条件。确保迷你植体尽可能平行放置，以确保咀嚼力的均匀分布至关重要。
在验证正确的扭矩后，我们将套环放置在植体上，并移除了活动义齿。在套环下方插入了一根橡胶管，在重新衬里阶段非常有用，防止树脂卡在凹陷处。随后，我们检查了义齿的被动性，并插入树脂进行闭口重新衬里。硬化时间后，我们从口腔中取出义齿，发现套环已嵌入义齿基底。
最后，我们检查了预接触和咬合，以确保义齿的完美功能。然后，患者被详细告知术后护理和新稳定义齿的使用方法。

Conventional mini implant surgery in the edentulous mandible is in most cases, a very quick and minimal invasive procedure. The implants are usually placed trans gingivally and if initial primary stability is achieved then they can be loaded immediately following the surgery.

Case description
68-year-old man, fully edentulous, smoking patient, lack of medical history.
Surgical dental history:
– maxillary rehabilitation by full implant-supported bridge
– failure of 2 mandibular implant surgeries
What are mini implants?
Mini implants are in all respects implants, but with a small diameter, not exceeding 3 mm.
They are produced in a titanium alloy, which is classified as grade 5, and has excellent mechanical properties. They have a sandblasted and etched surface which once inserted into the bone undergoes osseointegration such of that of implants with a larger diameter.
We present you a Surgical Clinical Case with Flapless Technique performed by Doctor Aldo De Blasi using SD Mini Implants. You will be able to observe all the steps necessary for the stabilization of the lower prosthesis in the interforaminal region.
A 55 year old female patient was referred to our office for a full mouth rehabilitation. Upon clinical examination and a CBCT, we have decided to implant 4 EL C-Tech conical Morse tapered connection implants in the upper jaw for a bar retained over denture and due to financial considerations; was to perform extraction of all remaining lower teeth and immediate post extraction implantation of SD C-Tech mini dental implants. A full muco-periosteal flap was released, teeth were extracted, an alveotomy was performed to achieve an optimal bone platform for the SD mini dental implants and to obtain a bigger vertical dimension for the overdenture!
A 58 years old female patient has come to our clinic for lower jaw rehabilitation. After the clinical examination and OPG, We have decided to extract tooth 33, which is the only one remaining. As thepatient has not accepted a big augmentation procedure, we have decided to implant 4 C-Tech SD mini dental implants for retention and stabilization of the lower denture.
