About this trial
Subjects with severely atrophic mandibles were treated with implants and implant-based restorations. Subjects will be required to consent to study participation and data processing according to General Data Protection Regulation (GDPR). Implant positions were planned digitally in a dental software DTX Studio, and implants placed with navigated surgery (Nobel Biocare X-Guide). Implants eligible for this study must be placed 2 mm or less from the alveolar nerve. Implants placed are NobelParallel TiUnite and NobelActive TiUnite. All subjects were followed up for 1 year after surgery to monitor success and adverse events related to the alveolar nerve. Data analysis will include demographics, medical history, Cone-beam Computed Tomography (CBCT) scans/peri-apical x-ray data, soft tissue parameters, and adverse events.

Subject signed consent form
Subject signed GDPR form
Disqualifiers

implant placement using navigated surgery near alveolar nerve
Procedure/SurgeryDental implant placement in proximity of alveolar nerve (within 2 mm) using navigated surgery.
Treatment groups
Trial outcomes
Primary outcomes
Treatment success after 1 year of implant placement
Treatment success is defined specific to this study as: * The implant supports a dental prosthesis * No adverse event related to the alveolar nerve * No or only minor bone loss around the implant
Secondary outcomes
Safety assessment with focus on alveolar nerve
The safety of the procedure will be evaluated based on the data collected from the adverse events and device deficiency issues. Based on the seriousness of the event it is categorized as either: * Adverse Event (AE) * Serious Adverse Event (SAE)• Adverse Device Effect (ADE) Serious Adverse Device Effect (SADE) * Unanticipated Serious Adverse Device Effect (USADE) * Device Deficiency (DD) Known issues associated with dental implant surgery include, but are not limited to, excessive bleeding during surgery, pain, alveolar wall fracture, partial or total anesthesia after surgery.
