Reshaping Componeer: tips and tricks 1

Daily use of EGRs (Esthetic Guided Restorations) allows to combine esthetics and function in a simple way. Four sizes EGRs help the clinician to solve almost every case of every patient. However, these Componeer shells are available only in one shape and this could represent a limitation in some clinical situation like crowding, diastema or when we need to change the teeth shape or gingival profiles. Nevertheless, changing the shape of an EGR is easy. After choosing the right size, is possible to change its shape using discs. If it is necessary to shorten them, we suggest you to make it at the cervical level without touching the incisal edge. It’s thus possible to create a new cervical profile, whose design will modulate the soft tissue healing.

A female patient, age 17, showing spacing between upper teeth, due to an altered Bolton index. In order to achieve a canine class I relationship, diastema in front teeth were necessary and the patient asked for the closure of these spaces. No prep semi-direct veneering using EGR was suggested for the upper central and lateral incisors.
After width and length measurement, 4 “L sized” veneers were chosen. Due to the triangular shape of the patient’s teeth, a reshaping of EGR was necessary. Moreover, changing the gingival profile allowed us to modify and align the periodontal curve on 11 and 21.

Conclusions

Reshaping EGR in daily use is very easy and it allow to facilitate a ideal customization of the shells in every smile.
