Filter by:This project consists of placing dental implants at extraction sites. Bone drilling and implant placement are performed using the flapless method with the use of a surgical guide allowing guided surgery. After implant placement, temporary teeth are immediately made and placed on the implants to guide the gingival contour. Bone and soft tissue retraction at the implanted sites are measured radiographically and digitally using surface scan superimposition over a 12-month period.
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.
The objective of the present study was to evaluate the effectiveness of surgical esthetic crown lengthening using digitally assisted 3D printed surgical stents in management of excessive gingival display due to altered passive eruption.
The purpose of this study is to evaluate the effect of printing layer thickness on accuracy of computer aided surgical guide
