tooth-limited (single-tooth) gaps and free-end situations/shortened dental arches
- the patient has been informed about the scheduled follow-up examinations and agrees to attend them
- systemic diseases that preclude implant surgery (e.g. uncontrolled diabetes)
- all contraindications for oral surgery
- Chemotherapy or radiotherapy in the head and neck area
- chronic inflammation (e.g. rheumatoid arthritis)
- systemic diseases and metabolic disorders that are associated
with bone lesions or bone healing
- the use of medication that influences or disrupts bone remodelling (e.g. bisphosphonates)
- intraoral infections
- patients who are unable to perform adequate oral hygiene
- factors which, in the opinion of the examiner, prevent completion of the examination, e.g. unreliability
