Introduction: the placement of a dental implant has been performed for several years using the freehand technique, with the current highlight being the support of surgical guides.
Objective: to describe a clinical case using two surgical guides to perform ridge regularization and the placement of dental implants under the All-on-Four concept.
Case Presentation: a 34-year-old female patient with generalized chronic periodontitis and advanced mobility in the lower incisors, presenting pain, halitosis, and aesthetic alterations. After clinical and imaging evaluation, multiple tooth extractions and rehabilitation through guided surgery were planned. Two surgical guides were designed: the first aimed at alveolar ridge regularization and the second for the placement of four mandibular implants. During surgery, block extractions were performed, guides were seated with fixation pins, controlled drilling was carried out, and implants were placed. Straight and angled abutments were installed according to position, and a provisional prosthesis was adapted five days later, with shortened occlusion up to premolars to favor healing. The patient evolved favorably, with adequate primary stability and planning for a future definitive prosthesis.
Conclusions: the data show that surgical guides manufactured through 3D printing are statistically precise for guided implant surgery. These guides offer significant advantages such as high accuracy, ease of fabrication, waste reduction, and shorter laboratory working time, which contributes to improving the profitability of the procedure.
