Success and Safety of the Implant Placement Using Navigated Surgery

The study aims to evaluate the success and safety of immediate navigated implant placement in the atrophic mandible or post-extraction sockets near the alveolar nerve, as an alternative to guided bone regeneration followed by delayed implant placement.

This single-center retrospective study includes 20 subjects with severely atrophic mandibles or post-extraction sockets, followed for 1 year after implant placement.

The primary objective is to assess treatment success, defined as the implant supporting a dental prosthesis, no adverse events related to the alveolar nerve, and minimal bone loss around the implant. The secondary objective focuses on safety, particularly concerning the alveolar nerve. Subjects must meet specific inclusion criteria, such as implants placed within 2 mm of the alveolar nerve and being at least 18 years old and must have signed consent forms. Exclusion criteria include the absence of 1-year follow-up data.

Data collected includes demographic and medical history, plaque, bleeding, and gingival indices at pre-treatment and 1-year follow-up, and radiographic exams (CBCT and intra-oral radiographs) to assess bone levels. Written informed consent is required, and all data is de-identified and transferred to Switzerland for analysis, complying with EU regulations. This study aims to provide a less invasive alternative to traditional methods, potentially reducing the number of surgical interventions needed.
