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.

Group 1. Immediate implant placement and temporary closure of tapered implants with a custom-made composite shaper after tooth extraction with bone augmentation by using allogeneic bone.
- Non-traumatic extraction.
- Palatal position of tapered implant for premolars and centred position for molars (more commonly - in the septum) 3-4 mm below the buccal gum line or 1-2 mm below the bony protuberance.
- For premolars, the implant is placed palatally 2-3 mm to the buccal bone wall, for molars 2-3 mm to the buccal and lingual wall.
- Implant insertion.
- "Jump distance" sealing with allogeneic bone.
- Temporary closure with a composite shaper.
- Cone beam computed tomography with Carestream machine.
- Taking a photo.
- Scan with 3Shape TRIOS4 scanner.
After 3 months, a cone beam computed tomography is performed to evaluate changes in the crestal bone, the temporary restoration is screwed off and the presence/absence of bleeding is recorded. A digital impression is taken for a zirconium oxide crown made on Ti base and to assess soft tissue changes.
The change in the buccal vertical bone level will be measured as the difference between the former and the new vertical distance from implant platform to the buccal alveolar crest.
While the change in the buccal horizontal bone dimension will be measured as the difference between the former and the new horizontal distance between the implant and the outer surface of the buccal plate. Both measurements will be taken using CBCT, one immediately after the surgery and the other one 3 month later.
Intraoral scans with 3Shape Trios4 dental scanner will be taken to compare soft tissue stability. Measurements will be taken before, immediately after the surgery and 3 month later. By using STL files it will be possible to compare soft tissue stability.

Time Frame |
---|---|---|
Stability of crestal bone
Time Frame: Before surgery, immediately after surgery, 3 moth, 1 year follow up
|
To compare crystal bone stability CBCT will be taken before surgery. , immediately after surgery, after 3 month and a follow up after 1 year. The change in the buccal vertical bone level will be measured as the difference between the former and the new vertical distance from implant platform to the buccal alveolar crest. While the change in the buccal horizontal bone dimension will be measured as the difference between the former and the new horizontal distance between the implant and the outer surface of the buccal plate. Both measurements will be taken using CBCT, one immediately after the surgery and the other one 3 month later |
Before surgery, immediately after surgery, 3 moth, 1 year follow up
|
The changes of stability of soft tissue
Time Frame: Before surgery, immediately after surgery, 3 month, 1 year follow up
|
Recession (REC) state of the gingival/mucosa border - registered by means of a periodontal probe from the incisal edge to the border of the medial, zenith and distal zones. There are taken scans with 3Shape Trios4 before surgery, immediately after, then 3 month and 1 year follow up to compare soft tissue stability |
Before surgery, immediately after surgery, 3 month, 1 year follow up
|
The change of position of implant using surgical guide
Time Frame: Before surgery and immediately after surgery
|
To compare implant position accuracy using surgical guide, the following two things will be compared: DICOM after the surgery witch contains information on the implant position in the bone and the STL file witch contains information on implant position before the surgery. There are taken cone beam computer tomography before and immediately after surgery, then 3 month and 1 year follow up. |
