Practical stress absorption by means of modified abutments. Case presentations

To improve the success rates of implants, numerous clinicians suggest progressive bone loading. The effectiveness of progressive loading can be enhanced by the use of stress-absorbing components. This paper reviews a polyoxymethylene intramobile element, which provides a resilient connection between the implant and prosthesis and reduces the stress transmitted to the implant and supporting bone, resulting in an improved long-term performance. This paper also introduces a relatively new intramobile connector system, which provides stress absorption and distributes the masticatory load in physiologic manner to the bone surrounding the implants. Types of bone and their locations in the mandible and the maxilla are discussed. Four case reports are used to illustrate the clinical procedure. The learning objective of this article is to expand the knowledge of available enhancements in stress absorption.
