Dental Anxiety Clinical Trial
Official title:
Closure of a Guided Immediate Implant Placed in the Extraction Socket With Bone Augmentation in the Lateral Area of the Maxilla or Mandible, With a Temporary Composite Abutment vs With a Custom-made Zirconium Oxide Abutment.
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: 1. Males and females at least 18 years of age or older. 2. One implant per patient. 3. 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. 4. Lateral individual teeth (premolars and molars). 5. Class I extraction socket (intact buccal wall) or class II (1/3 of buccal wall). 6. The gingival contour of the tooth to be extracted - without recession. 7. Adjacent anterior teeth have no periodontal loss. 8. There are no implants in the adjacent teeth. 9. Non-traumatic tooth extraction, which results in intact walls of the socket. Exclusion criteria: 1. Deep occlusion (severe, class II). 2. The patient smokes a lot (more than 10 cigarettes per day). 3. Systemic disease (osteoporosis). 4. No initial stability has been achieved after the implant insertion procedure.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Stability of crestal bone | 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 | |
Primary | The changes of stability of soft tissue | 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 | |
Primary | The change of position of implant using surgical guide | 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. |
