Brief Summary
The aim of this comparative RCT is to evaluate the differences between the entire digital, the combined digital-analogic and the entire analogic workflows of implant-supported and teeth-supported prostheses. It is a three-arms comparative study. The 60 patients are divided into three groups:
- fully digital workflow
- combined digital and conventional workflow
- fully conventional workflow For each patients were evaluated the interproximal (IC) and occlusal contact (OC) and impression time (IT) and the patient satisfaction through a VAS scale. The null hypothesis is that are no differences between the three groups for each parameter.

Outcome Measures
Primary Outcomes (4)
Entity of interproximal contact
Precision of interproximal contact between prosthetic crown and adjacent teeth. It was measured by the clinician evaluating the resistance to the sliding of waxed dental floss. The clinician gives to the interproximal contact a score from 0 to 4, where 0 is considered as an absence of resistance (open space between crown and adjacent teeth) and 4 is the total impediment to the floss slide (the crown and the adjacent teeth are too close to have a correct interproximal contact)
2 weeks after definitive prosthesis delivery
Entity of occlusal contact
The entity of contact between prosthetic crown and antagonist teeth was evaluated with a dichromatic articulating paper in order to identify any static and dynamic alterations in occlusal contacts that must be corrected. The clinician gives a score from 0 to 3 where 0 is the absence of contact between crown and antagonists, 1 is a correct contact between them that needs no corrections, 2 there is a slight altered contact that requires minor corrections and 3 there is an altered contact between the prosthetic crown and their antagonists which requires major corrections.

Impression time
Length of time useful to take impression expressed in seconds
2 weeks after definitive prosthesis delivery
Patient satisfaction degree
Patient satisfaction through a VAS scale. The patients is asked to make a mark in an unnumbered line ranging from 0 to 5 where 0 represents maximum comfort and 5 represents a very bad experience. The scale is 5 cm long so the clinician next measures the distance (in cm) from 0 to where the mark was placed by the patient.

Study Arms (3)
Fully digital workflow
EXPERIMENTALPatients of this group are subjected to entire digital workflow, from the digital planning to the delivery of definitive zirconia fixed dental prosthesis
Combined digital-conventional workflows
EXPERIMENTALPatients of this group were subjected to every digital steps as the "fully digital workflow" arm, except for the impression that includes analog material (silicones).
Fully conventional workflow
ACTIVE COMPARATORPatients of this group follow the entire analog protocol. All the procedures exclude digital involvement.
Interventions
The intervention that was administered was a full digital workflow. It includes an initial digital planning, an optical impression with intraoral scanner and a CAD-CAM milled zirconia crown. No analog materials were used.
The intervention that was administered was a combined digital and traditional workflow. The initial planning was digital, then the impression was performed with analog impression material (silicones) and the final zirconia crown was CAD-CAM milled, with a digital procedure.
The intervention that was administered was a conventional workflow that doesn't provide any digital step. The impression was taken with analog material (silicones) and the final prosthesis was a metal-ceramic crown, realized on plaster cast.
