Digital partition bonding for porcelain veneers guided by sequence 3D printing templates

doi:10.7518/hxkq.2022.03.019

Abstract

Abstract:

Obtaining optimal enamel bonding is a common recommendation to ensure the retention, edge closure, and clinical service life of porcelain veneers. Bonding surface is determined after tooth preparation. More or less dentin exposure often occurs due to the uneven thickness of the enamel. Identifying the enamel or dentin on the bonding surface and adopting the “selective etching” technique are useful to obtain the maximal bonding strength. Naked eye recognition in “selective etching” has uncertain results and is experience-based, whereas the proposed technique controls the preparation depth through the first target restoration space template to obtain the accurate enamel and dentin subarea. It is mapped to the second bonding template, depending on the treatment carried out on the enamel and dentin surface, to accurately predict the adhesion of porcelain veneers.

Key words: porcelain veneer, selective etching, sequence 3D printing template, partition bonding, target restoration space
