A Clinical Study on Implants With TiUltra Technology and Associated Prosthetic Components

Primary Objective: The primary endpoint is to evaluate the change in the marginal bone level from definitive prosthetic placement (baseline) to the 5-year follow-up visit.

Secondary Objective:The secondary objectives of this clinical investigation are:

* To evaluate the change in the marginal bone level from definitive prosthetic placement (baseline) to 1-year and 3-years follow-up visits * To demonstrate cumulative implant survival and success rates from definitive prosthetic placement to 5 years follow-up visit * To demonstrate cumulative prosthetic survival and success rates to 5 years follow-up visit * To evaluate soft tissue outcome (as measured by bleeding index, plaque index and gingival index) to 5 years from definitive prosthetic placement. * To evaluate SADE, USADE, ADE and DD from implant insertion until 5 years follow-up visit.

Study design: This is a multicenter, prospective, non-interventional study in which a total of 1000 subjects in need of a single, multiple or full arch restoration in any region of the mouth (healed or extracted) will be treated in up to 30 study centers. The study devices are divided into four groups:

* Group 1 (G1): NobelActive TiUltra implants (3.0, NP, RP, WP) * Group 2 (G2): NobelParallel CC TiUltra implants (NP, RP; WP) * Group 3 (G3): NobelReplace CC TiUltra implants (NP, RP) * Group 4 (G4): Nobel Biocare N1 TiUltra TCC implants (NP, RP)

Subjects will be consecutively included provided they meet all of the inclusion criteria and none of the exclusion criteria. Eligible subjects who provide their informed consent for participation will be enrolled into one of four groups, each sized to 250 individuals. They will be treated with the corresponding implant system assigned to the group. The allocation into a certain group is only driven by the subject's clinical and restorative requirement and standard of care at the enrolling study clinic. Each subject will be followed for 5 years after definitive prosthetic placement . Possible dropouts and withdrawals, as well as possible serious adverse (device) events, will be carefully monitored during the entire study period

Sequence of treatment: As part of the screening process each subject will undergo a pre-treatment standard of care examination to record demographic characteristics and medical history. The subjects will be informed of the treatment possibilities according to clinic standard of care and about the study. Depending on the clinical indication, clinician preferences and desired esthetic solution the subject will be enrolled into one of the four previously described groups (G1 to G4). Implant surgery-, bone and tissue regenerative- and prosthodontic procedures shall be performed according to IFU and standard of care. Implants may be placed in either healed or extraction sites utilizing one-stage or two-stage surgical protocol with immediate, early or delayed loading to restore single missing tooth, partial or fully edentulous jaws. The treating clinician should decide individually when definitive prosthesis installation is suitable for each subject. Standard of care follow-up visits should be scheduled as close as possible to 1-, 3- and 5- years after definitive prosthetic placement, to ascertain a homogenous data set. Deidentified periapical radiographs from each subject visit shall be uploaded to the study eCRF. All images will be forwarded to the core lab for independent analysis. As part of the screening process each subject will undergo a pre-treatment standard of care examination to record demographic characteristics and medical history. The subjects will be informed of the treatment possibilities according to clinic standard of care and about the study.
