special _ implants I _Discussion Drilling free hand into the prosthesis with no guide can result in oversized access holes and wasted chairside time. The primary goal of the methoddescribedhereistomaximiselaboratory procedures in order to reduce chairside time. We also minimise the size of the access holes, which reduces the damage to the prosthesis. Delegation of the construction of the device to a technical assistant can further reduce cost, for both the patient and us. Thereby, a task to which we look forward with trepidation can be reduced to a minor inconvenience. By minimising the diameter of the access holes, we increase the probability that the pros- thesis can be returned to the patient after dealing with the reason for removal. Once the prosthesis has been removed from the mouth, there are two options. Firstly, we could consider the abut- ment/prosthesis as a single item. After inspection and cleaning, the prosthesis can be replaced. Had the abutment screw become loose, then the grain structure of the screw may have become elon- gated and the screw should be replaced. The second option is separating the abutment from the crown or bridge. When they cannot be separated by mechanical means, they can be separated by gentle heating in a furnace. Slowly heattolessthan200°Cforfiveminutes,thenthe abutment and prosthesis should separate very easily. Allow to cool to room temperature slowly, then inspect porcelain for defects before return- ing to the patient._ I hereby agree to receive a free trial subscription of (4 issues per year).I would like to subscribe to for € 44* for German customers, € 46* for customers outside of Germany, unless a written cancellation is sent within 14 days of the receipt of the trial subscription.
