PREVENTION AND MANAGEMENT OF FREQUENT IATROGENIC DAMAGE IN THE PREPARATION OF ABUTMENT TOOTH PROCEDURES IN FIXED PARTIAL DENTURE

Background: In dentistry, dentists have to work in a small area that allows iatrogenic damage to occur during the preparation of abutment denture bridges, these damages can occur in adjacent teeth, soft tissues, and pulp. Prevention of damage and the need for handling if iatrogenic damage occurs need to be considered because it will affect the success of treatment and hinder the maintenance of dental health in the long term. Objective: This literature review aims to determine the types of iatrogenic damage that often occur in the preparation of tooth abutments procedures and their prevention and management. Results: The reviewed journals found that the highest prevalence of iatrogenic damage occurred on the proximal surfaces of adjacent teeth. Prevention can be done using rubber dams and matrix bands, making thin "lip" of enamel, mouth mirrors, and dental loupes. To treat this iatrogenic damage, polishing can be done with a soft-lex disc, composite resin, surgical crown lengthening and orthodontic extrusion. Conclusion: This review shows that iatrogenic damage to adjacent teeth is the most common iatrogenic error in the preparation of denture bridge abutments. The use of matrix bands, rubber dams, mouth mirrors, the manufacture of thin “lip” of enamel, and dental loupes can be used to prevent iatrogenic damage in abutment preparation procedures. Composite resins and soft-lex discs can be used to treat damage to rough tooth surfaces.
