Please assess the completion status of the following clinical trial:

Trial Title: Comparison of Individual Computer Aided Design/Manufactured (CAD/CAM) - Based Implants Consisting on Hydroxylapatite and Titanium to be Used in Cranioplasty

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE3
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Skull defects without the possibility to be covered with the missing own bone~2. Size of the defect ≥ 16 cm2~3. Age ≥ 18~4. Written informed consent of the patient~Exclusion Criteria:~1. Active tumor~2. ASA 4 classification~3. Allergic disposition to ceramic or titanium~4. Concomitant participation in other clinical trials~5. Pregnant or nursing women~6. Expected low compliance~7. HIV positive~8. Active drug abuses

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Titanium (Type: ACTIVE_COMPARATOR): Titanium implant for cranioplasty. Titanium implants are used since 10 years in Germany because of their high biocompatibility and accuracy of fit.
- Hydroxylapatite (Type: EXPERIMENTAL): Hydroxylapatite (CustomBone) implant Hydroxylapatite implants are used since about 3 years in Germany. As this material is very similar to human bone structure an improved osteointegration has been observed.

Based on this trial design, predict the completion outcome and termination type (if applicable).
