Study of Hard and Soft Tissue Behavior Around Abutments on Implants.

Purpose: To compare the loss of peri-implant tissue by means of radiographic and digital analysis of a zirconia prosthesis placed immediately and delay loading. Materials and methods: 60 consecutive patients with the need for a full-arch rehabilitation were selected and divided randomly into two groups: Group A: Conventional dental extraction, placement of 6 to 8 implants. Placement of the multi-unit prosthetic attachment and finally in the same week the placement of the definitive monolithic zirconia prosthesis on implants. Group B: Conventional dental extraction, placement of 6 to 8 implants. Placement of prosthetic and provisional attachment. After 3 months, place the definitive prosthesis. Assess volumetric changes using radiographic and optical scan techniques. The number of implant failures, prosthetic incidents and bone loss around the implants will be evaluated. The data will be evaluated 3, 6, and 12 months after the operation.
