Incisors Single-Unit Rehabilitation With Narrow GM Implants
Incisors Single-Unit Rehabilitation With Narrow GM Implants: Observational Prospective Study
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.
Devices will be used according to standard routine in daily practice, according to all indications as specified by the manufacturer in the instructions for use (IFU).
55 patients (needed to obtain a sample size of 55 implants) will be followed for 36 months and monitored for Adverse Events by the Investigators until the last protocol-related procedure of a patient is completed.

Detailed Description
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.
Data concerning the studied variables will be collected following the procedures and assessments plan by fulfilling the Case Report Form (CRF), in the following stages: First visit (Screening); TP - Implants placement; T0 - Implant Loading; TF - final prosthesis T6, T12, T24 and T36 - 6, 12, 24 and 36 months, respectively, after implant loading.
Panoramic radiographs, periapical radiographs, and computed tomography (CT) scans will be obtained from the region of interest before surgery, for surgical planning. Additionally, standardized digital periapical radiographs will be taken in a usual daily practice frequency, as determined by the investigator: after implants placement (TP - immediately or within 1 week after implant placement) and during the post-operative stages (T0, TF, T6, T12, T24, and T36) to assess the osseointegration process, changes in peri-implant bone level as well as prosthetic settlement and integrity.
Moreover, soft tissue evaluation will be conducted at the pre-treatment (Screening visit), for the regions to be rehabilitated with the study implants and in the postoperative period, at T0, TF, T6, T12, T24, and T36, for all study implants.

Time Frame |
---|---|---|
Peri-implant bone level change
Time Frame: up to 36 months

Periimplant bone level
Time Frame: up to 36 months

The peri-implant bone level will be measured on the periapical radiographs obtained as the distance between the coronal margin of the implant shoulder and the most coronal point of the peri-implant bone, on the mesial and distal surfaces of each implant.
The horizontal measurement of the remodeling will be done, when there is no bone contact in the cervical part of the implant.
This measurement will be performed from the superior site of the bone crest to the lateral edge of the implant, perpendicular to the long axis of the implant.

|
up to 36 months
|
Prosthetic Success
Time Frame: up to 36 months
|

Patient Satisfaction with treatment: questionnaire
Time Frame: up to 36 months
|
Portuguese translation of the OHIP-14 [20,21] (Annex III) questionnaire will be used to assess Oral Health-Related Quality of Life (OHRQoL), as a measure of patient satisfaction with treatment.

|
Clinician Satisfaction with treatment: questionnaire
Time Frame: up to 36 months
|
The assessment will be performed by means of a questionnaire using a visual analog scale (VAS) in the form of a 10 cm horizontal line, where 0 (left end) indicates minimum satisfaction and 10 (right end) indicates maximum satisfaction.
The clinician will evaluate his/her satisfaction with the surgical procedure, experience with the use of the abutments, as well as with the surgical and prosthetic results obtained.
