Incisors Single-Unit Rehabilitation With Narrow GM Implants: Observational Prospective Study

The study protocol was reviewed and approved by an Ethics Committee (CE) in Brazil.

The Narrow GM Implants were designed for oral functional rehabilitation using dental implants, allowing for treatment of patients with different bone qualities in the region of lateral incisors in the maxilla or the region of lateral and central incisors in the mandible.

The objective of the study is to confirm the long-term safety and clinical performance of implants and abutments of the Narrow GM System in a daily dental practice setting, by means of a prospective collection of clinical data in an observational study using these devices. Additionally, from the collected data, the study aims to identify previously unknown side-effects and monitor the known side-effects and contraindications stated on the Instruction for Use (IFU), identify and analyze emerging risks on the basis of factual evidence and ensure the continued acceptability of the benefit-risk ratio with the intent to verify that the intended purpose is correct for all JJGC products involved in the procedure that get in contact with the patient.

The sample will be prospectively selected and will consist of 55 patients, with at least one edentulous site in the region of lateral incisors in the maxilla and/or lateral and central incisors in the mandible, presenting natural adjacent and opposing tooth, and who are qualified for rehabilitation with narrow implants and single-unit fixed prostheses. Informed consent in writing will be obtained from each patient participating in the study prior to any study-related procedure.

GM Narrow implants will be placed under local anesthesia by guided or conventional surgery - as chosen by the surgeon - and with adequate bone bed preparation, as recommended by the manufacturer. Multiple implants can be placed in the same patient, as indicated. Implants must be installed 2mm infra-bony.
