Description

数字植牙规划辅助组件的产生方法 Method of generating digital implant planning ancillary components

技术领域 FIELD

[0001] 本发明与植牙技术有关,特别是指一种数字植牙规划辅助组件的产生方法。 [0001] The present invention is related to implant technology, and particularly to a method for generating a digital dental implant planning ancillary components.

背景技术 Background technique

[0002] 按,公知的植牙技术中,大多着重在骨质环境的评估,而忽略了牙齿对咬优劣的情形。 [0002] press, known implant technologies, mostly focuses on the assessment of bone environment, while ignoring the merits of the case biting teeth. 一般认为考虑植体在齿颚骨头位置是最重要的一点,之后若植体在植入后,其轴向偏移幅度过大时,再利用有角度的支台齿进行矫正即可。 Explants generally considered that the tooth jaw bone is the most important point position, after the time when the explants after implantation, which is axially offset amplitude is too large, then the use of the angled abutment teeth to be corrected.

[0003] 上述做法并非最佳做法,其原因在于,骨质的优劣固然重要,但假如植体的轴向偏离对咬基准面,则上下颚牙齿对咬或咬物体时,植体所承受到的将不只是一个轴向力,而是再加上一弯曲力矩,过大的弯曲力矩将容易破坏该植体与齿槽骨的密合状态,且会减少植体的使用寿命,或造成植体在手术完成的一段时间后骨整合失败。 [0003] The approach is not the best practice, the reason that the merits of the bone is important, but if the axial deviation from the explant bite plane, the jaw teeth to bite or bite objects, the explants are subjected will not only to an axial force, but together with a bending moment, excessive bending moment will readily destroy the adhesion state of the implant body and the alveolar bone, and will reduce the life of the implant body, or cause explant surgery after a period of time to complete failure of osseointegration.

[0004] 再者,如果植体在植入后,其轴向歪斜幅度已经超过该支台齿所能矫正的范围时,则装上假牙后咬合面会整个偏离,牙齿咬合的功能将完全丧失。 [0004] Further, if the explants after implantation, the magnitude of axial skew has exceeded the range of the abutment can be corrected, the entire package will deviate from the occlusal surface, the dental occlusion complete loss of function of the dentures.

[0005] 有鉴子此,植牙时的植体位置、角度及轴向,即必须在植牙前即做好最佳的规划。 [0005] In view of this child, explants position, the angle and the axial direction when the implant, which must make the best planning i.e. before implant. 而通过计算机辅助的数字牙模来进行辅助植牙的规划,即是一种可能的选择。 And it is aided by computer-aided implant dental wax plan number, i.e., a possible choice.
