Inclusion criteria

Inclusion criteria: Only patients with an unremarkable medical history and general health who are to be treated by students who have no previous practical clinical experience in implantology will be included. All subjects must be over 18 years of age and must have signed a consent form. The participating patients have an indication for implant-supported fixed dentures. Only switching and free end gaps in the posterior region should be restored. The drilling templates used are thus anchored by teeth. Risk structures must have a minimum distance of 2 mm apically and 3 mm laterally from the planned implant position. The buccal and oral bone thickness must be at least 2 mm wide over the implant in the planning. There must be a minimum width of 3mm of fixed oral mucosa in the area of the planned implant shoulder. Only implants with a primary stability of >35 Ncm at insertion are included in the study.

Exclusion criteria

Exclusion criteria: Excluded are patients with general medical contraindications for oral surgery and patients with radiation in the head and neck area. Also excluded are patients with mental illness, alcohol or drug abuse, pregnant and nursing women, as well as patients with untreated periodontitis, severe bruxism, uncontrolled diabetes, poor oral hygiene and lack of motivation. Patients are also excluded if there is insufficient bone supply and thus an insufficient safety distance of at least 2mm from the risk structures or an insufficient supply of fixed oral mucosa in the area of the planned implant position. Non-consenting patients are also excluded as study participants.
