Post Market Clinical FoIIow up (PMCF) Medical Device (MD) of Z-Systems Monotype Zirconia Dental Product: Z5m Dental Implants Registry

Commercially pure (CP) titanium is the gold standard to produce dental implants because it has a huge volume of scientific publications over a period of more than 50 years, it is cheap and simple to produce (i.e., making dental implants economically "affordable") and comes in numerous specitic designs of screws tor various indications. That is why more than 95% of the implant market 5 dominated by titanlum.

However, there is an innovation trend to manufacture implants from more inert and biocompatible materials. Ceramic implants represent a valuable alternative for expanding the patient base of clinicians, especially in cases with challenging aesthetic demand. Furthermore, there has been a significant increase in the number of patients requesting metal-free dentistry or bio-holistic implant treatments.

In the past, ceramics were often branded as "inferior" quality due to its reputation as being brittle but the growing volume of scientific publications specifically an zirconia are demonstrating that lt is comparable in fracture-strength with titanium implants. There is a clear market niche for zirconia implants, especially in cases of:

• Aesthetic reconstructions in the anterior region, especially in patients with a thin gingival biotype
• Gingival recessions where a white colored implant is a great advantage
• For patients with a titanium intolerance/sensitivity
• For patients who prefer a bio-holistic/metal-free dental approach.

Today, clinicians are asking tor long-term clinical results of zirconia as a dental implant material. Therefore, Z-Systems AG is conducting this zirconia dental implant registry. A registry design was chosen because it will capture long-term benefits/risks from clinical routine without patient selection.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Absence of persistent subjective complaints	Absence of persistent subjective complaints such as pain, foreign body sensation and/or dysesthesia	12 months post-loading final prostheis
Absence of peri-implant infection	Absence of peri-implant infection with suppuration	12 months post-loading final prostheis
Absence of mobility	Absence of mobility of dental implant	12 months post-loading final prostheis

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Frequency of occurrence of device related Adverse Device Events (ADEs) and Serious Adverse Device Events (SADEs)	Secondary Safety Outcome is frequency of occurrence of device related Adverse Device Events (ADEs), Serious Device Events (SADEs). Measured by asking patient if any adverse events occured since last follow-up.	At implant surgery, up to 3 months, 6 months, 1-5 years post-loading with the final prosthesis (i.e., at every follow-up visit after prosthetic restoration)
Exploratory outcomes - complaints and incidence	Rate of complaints and incidents related to the medical device during the whole registry.	At implant surgery, up to 3 months, 6 months, 1-5 years post-loading with the final prosthesis (i.e., at every follow-up visit after prosthetic restoration)
Exploratory outcomes - clinical satisfaction	Clinical satisfaction measured on a Likert scale: 1 to 6, with 1 being "not satisfied at all" to 6 being "highly satisfied.	At implant surgery, up to 3 months, 6 months, 1-5 years post-loading with the final prosthesis (i.e., at every follow-up visit after prosthetic restoration)
Exploratory outcomes - patient satisfaction	The patient's assessment of function and aesthetics is recorded by his/her assessment of function, aesthetic appearance, implants, speech and self-confidence. The parameters are assessed by rating the degree of satisfaction on a 100 mm Visual Analogue Scale (VAS).	At implant surgery, up to 3 months, 6 months, 1-5 years post-loading with the final prosthesis (i.e., at every follow-up visit after prosthetic restoration)
