Primary Outcome Measures

Name	Time	Method
Based on a clinical follow-up of patients with a PEEK abutment, it will be investigated whether the prevalence of procedural complications can be expected to be less than 10 percent. For this purpose, dental indices will be collected and analyzed. <br>1. craniomandbular dysfunction (CMD)<br>2. damage to crowns on PEEK abutments<br>3. damage to the PEEK framework (primary crown / abutment)<br>4. discoloration tendency on PEEK abutments and PEEK primary parts)<br>5. plaque susceptibility (PI) <br>6. gingivitis (GI)<br>These indices provide information on the potential procedural complications that may be encountered during the study. <br>The primary study objective is the prevalence of procedural complications at the time of examination.

Secondary Outcome Measures

Name	Time	Method
Do the different methods of dental fabrication of PEEK abutments, namely milling and pressing, influence the frequency rate of procedural complications?<br>To answer the secondary objective of the study, the manufacturing method (milling or pressing) of the restoration should be requested from the responsible dental laboratory.
