Abstract

A micro-implantable apparatus and method for the stability assessment of a two-stage dental implant during osseointegration processes, whose detection mechanism is based on a transmission of a pulse wave signal from the upper opening of a implant and a subsequent analysis of the reflection waves that measures the changes in degree of mechanical interlock between the bone and the implant which comes as a result of the wound healing processes happened at the gap between bone-implant interface. The incorporation a surface coil in such device provides a mean to transmit and to receive the detection waves, which makes it possible for such device to be operated in a wireless setting. This device also includes an energy-storing capacitor, which serve as a temporary power supply unit to effectively eliminate the need for signal wires and power cores, which in turn further increases the applicability and safety of such device as a passive implantable apparatus.

4 / DOJJ V. Description of the invention (2) Introduce ^ λ to π i. The dilemma and problems caused by the above-mentioned denture installation method: In c, "artificial implant" is the best choice at present ^ "Tooth" is made of titanium metal. Titanium metal has a good A valley. It will not dissociate in the body and the environment to produce cytotoxic MAH. Thorough surgical procedures. The "artificial implant" can reach 0, / W has many advantages such as durability, beautiful appearance, large bite force, no loss of bone, and no need to sharpen the good teeth next to it. " Estimating the stability of artificial tooth root implants can be divided into two main stages according to their healing process: ^ ^ and-human stage. The factors that determine the stability of the root implant in the main stages include: the density and thickness of the alveolar bone, the choice of surgical methods, the shape and size of the artificial root implant. Based on the healing status achieved by the root implant in the main stage, the factors that affect the stability of the root implant in the secondary stage are determined by the bone regeneration and absorption mechanism between the tooth root implant and the alveolar bone junction. In recent years, the robustness detection methods for assessing the healing status of artificial tooth roots have mainly used non-destructive techniques in vibration theory. In this kind of method, it is common to use impulse force or sinusoidal wave to excite the vibration of the artificial tooth root, and monitor and analyze the resonance frequency (resonance frequency) or the so-called natural frequency (nat ^ ai, frequency ) To determine the density relationship between the alveolar bone and the artificial bone root.

However, it is difficult for the teeth in the posterior region of the oral cavity to be in the position of .0 + teeth (such as the position of wisdom teeth) to flush the ashes.符 # mallet smashing has its difficulties in construction. The present invention addresses the above problems, and develops an implantable artificial stability detection device. Therefore, the main root electrical system (_s) manufacturing technology of the present invention is designed to design— It is necessary to use microcomputer stability to sense the placement and method ", which is mainly a detection device and method for detecting the root and branch of the tooth before the artificial tooth root = and the denture. ~ &Amp;
