2. Treatment Concept<br />

Introduction<br />

It is known from general physiology that<br />

both non-loading and underloading of<br />

the bone induces degradation just as<br />

much as overloading (inactivity atrophy,<br />

pressure atrophy). The area between<br />

these two extremes is called normal<br />

loading. This consists in a balance<br />

between growth and degradation.<br />

Working with bridge restorations in conventional<br />

prosthetics has led to identification<br />

of consistently high rates of bone<br />

degradation in non-loaded or underloaded<br />

abutment teeth (Misch/Frost<br />

1990).<br />

W. Schulte recognized this in 1982 and<br />

proposed early (= immediate, if possible)<br />

implantation to offset atrophy of the<br />

periodontal structures, which commences<br />

immediately after tooth loss. The implant<br />

supports the alveolar bone and tooth-bytooth<br />

implant-supported rehabilitation<br />

prevents the bony areas from being<br />

either overloaded or subjected to inactivity<br />

atrophy (stress-shielding).<br />

Leverage Relations at the Implant<br />

Loading of the implant-bone interface is<br />

a result of the leverage relation generated<br />

by osseointegration-related resistance<br />

to the prosthesis load arm (equivalent to<br />

the supracrestal implant length plus the<br />

height of the crown above the implant<br />

shoulder). If this (IL) is less than 1 (CL),<br />

then the load must be reduced (e.g.,<br />

through prosthetic splinting).<br />
