The immediate postextractional implant insertion is a specific way of surgical approach to implanto-prosthetic treatment. This article addresses the indications, advantages, and surgical techniques of immediate postextraction insertion, illustrated with a clinical case. Objectives: presentation of the indications, advantages and surgical procedure of immediate postextractional implant insertion. Materials and methods: The present study considered the presentation of a case in which we opted for the insertion of implants immediately postextractionally as a therapeutic attitude. Results and discussions: The advantages and disadvantages of this therapeutic technique were represented as follows. The advantage of this technique is given by the shortening of the time necessary to complete the treatment until the prosthetic phase, the disadvantage being represented by the insertion of the implant in positions sometimes less advantageous to the prosthesis. Also, the fact that we could not preserve the alveolar ridge, keeping the bone volume necessary to insert the implant in the best position of the prosthesis by complying with the biomechanical principles, made over time, a series of complications that occurred due to vicious insertion of the implant and non-compliance with those biomechanical principles. Conclusions: The analysis of the case as a whole, represents the main premise from which any dental treatment must be started, so that the functionality of the prosthetic and aesthetic reconstruction will have to be taken into account when we choose the best treatment option
