Socket Shield, Connective tissue graft
Brief summary
The present study aims to compare the dimensional stability of the supra-implant complex following flapless immediate implant placement using two socket management approaches: the connective tissue graft and the socket shield technique. Three-dimensional volumetric analysis and cone-beam computed tomography (CBCT) will be employed to assess and quantify changes in soft and hard tissue thickness and height surrounding the implant site.
Detailed description
The current study will include 28 non-restorable single maxillary anterior teeth indicated for extraction. Patients will be randomly allocated into two equal groups. The test group will undergo immediate implant placement combined with the socket shield technique and a customized healing abutment, whereas the control group will receive immediate implant placement with connective tissue grafting and a customized healing abutment. A pilot surgical guide will be used for both groups. The primary outcome measure will be labio-palatal ridge dimension changes changes. Secondary outcome measures included labial soft-tissue volumetric changes, bone formation labial to the implant, vertical bone level changes and pink esthetic score. All outcomes will be evaluated after a 12-month follow-up period.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Soft tissue Volume gain/loss | one year | The volumetric analysis in this clinical trial will be performed to obtain profilometric measurements. intraoral scans will be taken at baseline, 6- and 12-month post-operative for each patient. The best-fit algorithm will be used to superimpose digital surface models, when comparing each area of interest (AOI) throughout out the follow up period. Unchanged neighboring teeth surfaces will be used as a reference for proper superimposition. In each patient, the AOI will be kept constant for all pairwise comparisons. The volumetric analysis software will calculate the overall buccal soft tissue volume loss/gain (mm3) within the AOI for each patient. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mid-facial gingival margin level | 12 months | linear change of the Mid-facial gingival margin pre- and after one year |
