Abstract

The typical biomechanical properties of an internal conical connection (ICC) are axial displacement and loss of preload. The axial displacement of an ICC without a vertical stop can cause the loss of preload and a lowered occlusion. The stress of an ICC is concentrated on the contact interface of the abutment and not on the screw, and during placement, it is important to choose a wider coronal wall thickness as much as possible. The ICC should also be placed below the level of the bone crest. During the restoration of an ICC, care should be taken to ensure an appropriate abutment shape and an accurate connection. To get the best clinical results, it is important to select its wall thickness and place it in the appropriate position to restore it adequately.

원추형 내부연결 임플란트의 독특한 생역학적 현상이 수직침하와 전하중 상실이다. 원추형 내부연결 임플란트에서 수직적 정지점의 부재로 발생하는 수직침하에 의해 나사의 전하중이 상실되고 교합이 낮아지는 현상이 유발된다. 원추형 내부연결 임플란트에 발생하는 응력은 나사가 아니라 지대주가 접촉하는 계면에 집중되므로 식립할 때는 가급적 상부직경이 두꺼운 임플란트를 선택하는 것이 중요하다. 원추형 내부연결 임플란트는 치조정보다 하방에 식립해야 하며 수복 시에는 적절한 지대주 형태와 정확한 연결을 가지는지 주의해야 한다. 최상의 임상적 결과를 얻기 위해서는 상부 직경을 잘 선택하고 적절한 위치에 식립하여 수복하는 것이 필요하다.
