Four splinted anterior crown

7 Nov 2018 - 1552

A 77 year-old patient approached our dental practice with a request for esthetic and functional rehabilitation of the maxillary anterior region. 

The initial intraoral examination found significant tooth substance defects in the maxillary anterior region as well as carious lesions in inadequately restored teeth 12-22. Furthermore, teeth 12, 21 and 22 were found to have a mobility grade of one. Besides horizontal bone resorption, X-ray imaging found no further abnormalities.

Teeth 23 and 24 were crowned (PFM crowns), while teeth 13-18 and 26-28 were missing. In the mandible, 35 and 45 were also crowned (PFM crowns), while the missing lower molars had been replaced by a partial denture.

A silicon impression (DMG Honigum Pro Putty) was taken in order to get a template for a semi-permanent restoration.

Caries were removed and teeth restored with a build-up, using a bulk fill resin composite (DMG Ecosite Bulk Fill).

After isolating the preparations with vaseline, the silicon key was filled with DMG LuxaCrown and repositioned in the mouth. 2 minutes after the mixing, the key was removed while the resin was in the elastic phase.

5 minutes after the mixing, the restoration was ready to be finished and polished.

In order to ensure a stable bond beyond the 6 months, a self-adhesive resin cement was chosen (DMG PermaCem 2.0).

The interim denture, created in the meantime to replace the missing teeth in the upper jaw, was also inserted following adjustment and activation of the retaining elements.

Conclusions

The semi-permanent restoration produced with DMG LuxaCrown is a stable restoration that enables esthetic rehabilitation and affords both the dentist and the patient a generous time frame and a reliable basis for periodontal therapy as well as further restoration.
