Acqua GM (Grand Morse) Helix implants present an optimized implant design with adapted treatment protocol, allowing for treatment of patients with different bone qualities. The objective of the study is to prospectively collect clinical data to confirm the long-term safety and clinical performance of Acqua GM Helix implants and GM prosthetic abutments in daily dental practice setting, by means of success and survival rates of these devices. Devices will be used according to standard routine in daily practice, according to all indications as specified by the manufacturer in the IFU (instructions for use). patients will be followed for 36 months after implant placement.
The study protocol was reviewed and approved by an Ethics Committee (CE) in Brazil. The sample will be prospectively and consecutively selected and will consist of patients who are 18 years of age or older, who are in need of one or more dental implants and who qualify for placement of Neodent GM Helix implants. Informed consent in writing will be obtained from each patient participating in the study prior to any study related procedure. Neodent Acqua GM Helix implants will be placed under local anesthesia and with adequate bone bed preparation, as recommended by the manufacturer. Multiple implants may be placed in a single subject. Implants will be placed 2mm below the alveolar ridge. The selection of the prosthetic component and loading protocol (late or immediate) will be conducted according to the need of each subject and to the manufacturer's instructions (IFU). Thus, implant immediate loading may be performed (at the discretion of the surgeon) when primary stability reach at least 32 N.cm and the patient present physiological occlusion. Data concerning the studied variables will be collected by fulfilling the Case Report Form (CRF), in the following stages: First visit (Screening); T0 - Implant(s) placement; TL - Implant loading; T6, T12, T24 and T36 - 6, 12, 24 and 36 months, respectively, after implant placement. A visit window of more or less one month is eligible for each of the planned intervals. Standardized digital periapical radiographs, computed tomography scans and photographs will be obtained in an usual daily practice frequency, as determined by the investigator.

Implant survival and success rates
Implant survival will be defined as no loss of the implant at each follow-up. Evaluation of implant success will be assessed based on the criteria proposed by Buser et al. (1990).
Time frame: 36 months after implant placement
Implant survival and success rates
Implant survival will be defined as no loss of the implant at each follow-up. Evaluation of implant success will be assessed based on the criteria proposed by Buser et al. (1990).
Time frame: 6, 12 and 24 months after implant placement
Prosthetic survival and success rates
Prosthetic survival will be assessed as the prosthesis remaining in situ at each follow-up, irrespective of its condition. Success will be defined as the prosthesis that remained unchanged and did not require any intervention during the entire observational period.
Time frame: 12, 24 and 36 months after implant placement
Patient Satisfaction: OHIP-14 (Oral Health Impact Profile) questionnaire
The Portuguese translation of OHIP-14 \[18,19\] questionnaire will be used to assess Oral Health Related Quality of Life (OHRQoL), as a measure of patient satisfaction with treatment. Scores will range from 0 (absence of negative impacts on oral health) to 28 (high frequency of negative impacts on oral health).
Time frame: 6, 12, 24 and 36 months after implant placement
Clinician Satisfaction: VAS (Visual Analogue Scale) questionnaire
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 be instructed to mark the position considered to best represent their degree of general satisfaction with patient treatment. The score will be measured in centimeters from the left end of the line to the marked point.
Time frame: Implant placement, 12, 24 and 36 months after implant placement
Rate of adverse events related to the implant, prosthesis, surgery and oral health
Determined by inquiring with the patient and clinical evaluation.
Time frame: Implant placement, 6, 12, 24 and 36 months after implant placement
