What is the optimal design for a prosthetic device?
What does custom design mean for a prosthetic device?
It refers to the choice of material, color, the spatial distribution of the dental arch elements (selection of shape type: oval, triangular, square), gnathological development and function, and the reconstruction of gingival orthopedics.

Zirconia framework on implant abutments—bonding technique

Treatment: Functional rehabilitation and harmonization of the dental arch using a Zirconia framework
Dentist: Dr. Daniele Catalano, private practitioner in Reggio Emilia at the Bludent Healthcare Facility
Treatment: Zirconia bridges and crowns on metal abutments using the bonding technique, with Noritake CZR feldspathic ceramic aesthetic veneering
Patient: Male, 60+ years old, seeking improved masticatory function, harmonization of the lower anterior appearance, and selection of the most suitable shape in harmonic proportion to the face.

Editorial:

The restoration of a lower anterior group on implants can be very challenging if one does not begin with a wax-up for analog or digital analysis.
The reconstruction of ideal orthopedic tissue for implant restorations of the anterior groups requires a global consideration of the relationship between the positioning of the prosthetic teeth and the pink orthopedic gingiva.
The choice of prosthetic components, from the provisional to the final structure, must be planned to achieve support with a biological design.
The finishing of the model and maximum precision in the articulator positioning determine the initial project cycle. (It is inconceivable to use simple articulators for complex prosthetic cases, as they hinder a clear design vision and are cumbersome to handle)
The design and study of the orthopedic gingiva, its frame based on anatomical standards, the volume of the framework with adjacent teeth, the relationship with antagonist teeth, and the proximal contact area.
The aesthetic shape depends on the incisal edge and the harmonization of the form, while the biological limit is dictated by the cervical area, where the emergence profile begins for proper labial support.
A cement space of 0.0040 microns was calculated within the zirconia restoration (cylinder area) to achieve a passive fit that compensates for any distortion.
The passivity of the prosthesis was verified using periapical radiographs.
Minimal occlusal adjustments were made after delivery, then both screws were tightened with a torque of 35 N, and the access holes were covered with Teflon and topped with light-cured composite.
Further panoramic and periapical radiographs were taken for subsequent verification of the prosthesis’s precision.
The patient was provided with instructions regarding post-treatment management.
