Abstract

Objective:The aim of this study was to present the technique of splinting anterior maxillary teeth using heat-pressed glass-ceramic material in a clinical case with long-term follow-up.Clinical Considerations:Various materials, including fiber-reinforced tapes, glass fibers, composite resin, and partial coverage metal frameworks, have been used as splinting materials with encouraging clinical results.Conclusion:As shown in the presented case, glass-ceramic heat-pressing materials can be used successfully for the splinting of anterior teeth.

Highlights

In cases of advanced periodontal disease, the destruction of the attachment apparatus may reach a level that some teeth may exhibit pronounced mobility or even signs of progressive mobility due to reduced periodontal tissue support
A feather-edge or knife-edge preparation makes it possible to minimize the needed preparation, maintaining more enamel layer intact, and for this reason are recommended for disilicate lithium restorations [19]
An important inhibiting factor in the use of the metal framework in the presented case were the diastemas of the teeth and the increased translucency

Summary

INTRODUCTION

In cases of advanced periodontal disease, the destruction of the attachment apparatus may reach a level that some teeth may exhibit pronounced mobility or even signs of progressive mobility due to reduced periodontal tissue support. Its mechanical properties may provide the option of even no preparation when there is sufficient occlusal space available or in cases of severely worn dentition when preservation of tooth substance is of utmost importance [16] When it comes to posterior regions fabricating a full contour crown using CAD systems out of lithium, disilicate can offer 360 MPa of strength through the entire restoration [12]. All innovative solutions offered by this ceramic system are widening the restorative treatment options; due to the excellent optical properties, the high mechanical resistance, the variability in clinical indications, and the different manufacturing techniques, it is no doubt one of the most promising dental materials in the realm of Digital Dentistry [18] This material can be bonded to residual enamel and dentin after etching of the inner ceramic surface with hydrofluoric acid (HF) and silanization, using the latest-generation dualcuring resin cement. A feather-edge or knife-edge preparation makes it possible to minimize the needed preparation, maintaining more enamel layer intact, and for this reason are recommended for disilicate lithium restorations [19]
