Atraumatic Zirconia Abutment Versus Customized Composite Healing Abutment in Maxilla or Mandible.

40 patients are included in the study, 20 patients in group 1 (=closure with composite material shaper; test group) and 20 patients in group 2 (=closure with custom-made zirconia oxide abutment; control group).Randomisation envelopes will be used for randomisation. Device under study: Straumann BLX, Roxolid® , SLActive® dental implants with a diameter of 3.5, 3.75, 4, 4.5 mm are used.Allogenic bone botiss maxgraft® cortical granules are used as graft material.Inclusion criteria:Males and females at least 18 years of age or older.One implant per patient.Prior to any study-related activity, the subject must voluntarily sign informed consent, be willing and able to attend scheduled follow-up visits, and agree to the collection and analysis of pseudonymised data.Lateral individual teeth (premolars and molars).Class I extraction socket (intact buccal wall) or class II (1/3 of buccal wall).The gingival contour of the tooth to be extracted - without recession.Adjacent anterior teeth have no periodontal loss.There are no implants in the adjacent teeth.Non-traumatic tooth extraction, which results in intact walls of the socket.Exclusion criteria:Deep occlusion (severe, class II).The patient smokes a lot (more than 10 cigarettes per day).Systemic disease (osteoporosis).No initial stability has been achieved after the implant insertion procedure.
