Digital impressions (intraoral scan)
6 months after the procedure, a 3D scan of the patient's mouth is performed with an intraoral scanner. No traditional impressions with pastes and trays.

The Circolare d'Autore® is the definitive fixed prosthesis in zirconia-ceramic that completes the Bilateral Sinus Solution™ (BSS) rehabilitation, applied about 6 months after the procedure. It covers the whole arch with 14 teeth, without fake gum, with a natural appearance. Every prosthesis is a unique handmade piece made to measure for the patient and does not require periodic replacement.
The Circolare d'Autore® (registered trademark) is the definitive fixed prosthesis designed to complete the implant rehabilitation with the Bilateral Sinus Solution™ (BSS) technique. It is applied about 6 months after the surgical procedure, when the osseointegration of the implants is complete and the gums have stabilised around the temporary prosthesis.
It is called "Circolare" because it covers the whole circumference of the dental arch (from molar to molar), and "d'Autore" because every prosthesis is a unique handmade piece, made to measure for the patient by a specialised dental technician under the supervision of the Nicola Lettera Team.
Main characteristics:
The explanatory video of the Nicola Lettera Maxillofacial Team illustrates the characteristics and advantages of the Circolare d'Autore®. It shows how the definitive zirconia-ceramic prosthesis differs from traditional composite resin prostheses, explaining why the absence of fake gum and the zirconia structure guarantee superior aesthetic results and permanent durability.

The Circolare d'Autore® uses zirconia (ZrO2) for the load-bearing substructure, with mechanical strength up to 1,200 MPa, biocompatibility and lightness. The aesthetic layered ceramic coating is applied by hand by the dental technician layer after layer with firings above 800°C, faithfully reproducing colour, translucency and morphology of natural teeth.
The Circolare d'Autore® uses the most advanced materials available in prosthetic dentistry:
Zirconia (ZrO2) is a high-strength ceramic material used as the load-bearing skeleton of the prosthesis. It is milled from sintered blocks with CAD/CAM technology. Properties:
The layered ceramic is applied by hand by the dental technician layer after layer, firing each layer in an oven above 800°C. This handmade process allows:
The realisation of the Circolare d'Autore® combines digital technology and craftsmanship: digital impressions with an intraoral scanner, CAD design of the zirconia structure, 5-axis CNC milling with micrometric precision, handmade ceramic layering in several firings, mouth trial and finishing, and definitive application with screwing onto the implants.
The realisation of the Circolare d'Autore® is a process that combines digital technology and dental craftsmanship. Here are the phases:
6 months after the procedure, a 3D scan of the patient's mouth is performed with an intraoral scanner. No traditional impressions with pastes and trays.
The technician designs the zirconia structure on the computer, defining shape, thickness and morphology of every tooth, respecting the patient's occlusion and aesthetics.
The zirconia structure is milled from a solid block with 5-axis CNC machines. Micrometric precision, tolerances below 20 microns.
The dental technician applies the aesthetic ceramic by hand layer after layer (dentine, enamel, background colours), firing each layer in an oven. Every prosthesis requires several layering and firing sessions.
The prosthesis is tried in the patient's mouth to verify shape, colour, occlusion and comfort. Any small adjustments are made in the laboratory.
The Circolare d'Autore® is screwed onto the implants with titanium screws. The prosthesis is definitive: it never needs to be removed except for periodic controls.
The Circolare d'Autore® differs radically from Toronto Bridge and All-on-4/6: it offers 14 zirconia-ceramic teeth without fake gum with permanent durability, while the alternatives have 10-12 composite resin teeth with fake gum and a lifespan of 4-5 years. The Circolare d'Autore® allows normal hygiene, has a very low risk of peri-implantitis and is a one-time investment without recurring costs.
| Characteristic | Circolare d'Autore® | Toronto Bridge | All-on-4/6 | Overdenture |
|---|---|---|---|---|
| Number of teeth | 14 | 10-12 | 10-12 | Variable |
| Material | Zirconia-ceramic | Composite resin | Composite resin | Acrylic resin |
| Fake gum | Absent | Present, abundant | Present | Present |
| Duration | Permanent | 4-5 years | 4-5 years | 3-5 years |
| Replacement | Never necessary | Every 4-5 years | Every 4-5 years | Every 3-5 years |
| Fixing | Fixed (screws) | Fixed (screws) | Fixed (screws) | Removable |
| Oral hygiene | Normal | Difficult | Difficult | Difficult |
| Peri-implantitis risk | Very low | High | High | Medium |
| Aesthetics | Excellent | Mediocre | Mediocre | Poor |
| Long-term cost | One-time investment | Recurring | Recurring | Recurring |
The Circolare d'Autore® offers natural aesthetics with ceramic teeth indistinguishable from real ones, permanent durability without the need for replacement, a complete arch with 14 teeth and all posterior molars, easy hygiene with dental floss and toothbrush as with natural teeth, biocompatibility of the materials and handmade custom realisation as a unique piece for every patient.
Ceramic teeth indistinguishable from natural ones. No fake gum.
Does not wear out, does not stain, does not need replacement. One-time investment.
Complete arch with all posterior molars for perfect chewing.
Separate teeth: dental floss and toothbrush as with natural teeth.
Zirconia and ceramic: hypoallergenic, non-toxic materials.
Unique handmade piece designed for every patient.
The fake gum (pink flange) is a typical element of traditional prostheses (Toronto Bridge, All-on-4/6, overdenture) that causes hygiene, aesthetic and health problems. The Circolare d'Autore® completely eliminates the fake gum thanks to the posterior anchorage: the teeth emerge from the natural gum like real teeth, facilitating hygiene and preventing peri-implantitis.

The maintenance of the Circolare d'Autore® is simple, as with natural teeth: brushing 2-3 times a day, dental floss, interdental brushes and semi-annual check-ups. It does not require specific products or particular techniques. The fixing screws are checked periodically and the prosthesis never needs replacement.

The transition from Toronto Bridge to Circolare d'Autore® represents an epochal quality leap: the Toronto Bridge is a composite resin prosthesis with fake gum lasting 4-5 years; the Circolare d'Autore® is in zirconia-ceramic without fake gum with permanent duration. The difference is comparable to that between a sheet metal body and a titanium one.
