Making the best out of your analogical world. Provisional implant-supported FDPs.

The use of implant-supported FDPs, in everyday practice, has become more and more popular, as the protocols have been simplified in the last two decades.
Moreover, immediate-load protocols are today well established in clinical practice and in the literature.
These changes are of course happily welcomed by patients, for whom this kind of rehabilitation is now comfortable enough to be accepted, as the dentist can today extract the teeth, place the implant and also provisionalize in a very short time span.
The fabrication of nice-looking provisionals is still challenging for the dental team, both because of timing and aesthetic expectations of the patient.
Moreover, the mechanical properties of the material should withstand a minimum of 6 months inside the patient’s mouth. In the meantime digital technology allows clinicians to fabricate printed surgical guides, printed/milled temporaries, ready to be screwed or cemented onto the implant(s).
This technological reality is working very well, and will be more and more our daily future. Nevertheless, the financial reality of dental practice has changed significantly the last 5 years and it is easy to observe that the technological promise does not always match with the economic reality, because the digital workflow is more expensive, whatever experts can demonstrate.
The purpose of this article is to present a simple and affordable way to produce nice and elegant implant-supported temporaries to fit with the analogical reality.

implants and abutments from occlusal

This 56 years old female patient was affected by multiple, severe apical infections on FDP-supporting roots of teeth 22, 21 and 12. 5 implants 5 (V3 MIS NP) were placed after extraction. As you can see, we were not able to place the implant on 22 in the ideal position because of the severe lack of bone volume, and the impossibility to have an angulated multi unit abutment on a narrow platform implant.
The prosthetic treatment plan included an implant-supported FDP from 15 to 22, and natural tooth FDP from 23 to 27.

wax-up for implant supported fdp

The whole arch was first waxed-up in order to recreate a proper lip support, a nice smile line, and aesthetics. The patient explicitly asked for very white and aligned teeth, with not much customization.

prostodontic wax up

In order to keep tooth proportion close to ideal, and compromising with the severe bone resorption, an artificial gum is used in the cervical area in the anterior zone.

putty and light silicone index

A silicone index was fabricated on the wax-up, with a putty silicone (Lab silicone, Henry Schein) relined with a light-bodied silicone (Honigum light,  DMG to get an accurate replica of the texture.

The temporary prosthetic cylinders were cut, in order to let the silicone index fit.

injecting resin in silicone index

The silicone index is first fit to check insertion, then a reinforced bis-acryl resin material (LuxaCrown, DMG)  is injected in the silicone index . Injection has to start from the bottom of the incisal edge up to the cervical part.

resin provisional prosthesis with excess

After the setting time (5 minutes), the silicone index is removed. Some small bubbles can occur, especially in the incisal and buccal area. This depends on how smooth the index is fit, and how firmly it’s hold in position during setting. This small bubbles can be filled with a drop of flowable composite (LuxaFlow-Star, DMG) or can be relined as well with LuxaCrown again before starting the polishing sequence.

pink composite for provisional prosthesis

Pink composite (Gradia Pink GC) is added in the cervical area.

coarse grit silicone diamond wheel

A coarse-grit silicone disc is used for the primary polishing in order to finalize the shape.

rough implant prosthesis

After a couple of minutes both the white and pink are finished, and we can proceed to the actual polishing.

polishing paste on temporary prosthesis

A universal diamond paste is applied on the surface to get the gloss.

polishing prosthesis with brush

Polishing pastes, combined with miniature polishing brushes (HATHO) work impressively well on the LuxaCrown resin, thanks to its composition.

The same brush is used without the diamond paste. Texture changes easily with this simple polishing technique.

In 5 minutes total, the resin is glossy, and the value is improved, while texture is maintained.

The aim of this article was to share simple tips and tricks for your everyday practice, while complying with a common financial reality.
This analogical approach is efficient on different sides:
– It’s easy to do
– It’s quick
– Durable for the scope
– Esthetic
Of course digital options work very nicely, but they do cost much more and can be longer too. The aim is not to compare the two very different workflows, but it’s to highlight the pros and cons of each.
The challenge for the dentist is not to use one technique instead of the other, but to try to make the best synthesis of the analogical and the digital workflows, and get the best out of each.
