INTRODUCTION TO SOCKET SHIELD
Why & When Socket Sheild?
Can we predict the collapse ?
Can we stop the collapse?
Even if we follow the parameters for immediate implant, is it enough?
According to this paper, bone loss is almost guaranteed in most of your cases.
Total tooth extraction leads to some level of bone loss especially when we consider the bundle bone of the buccal cortical plate (Araujo & Lindhe)
Consequences :
1.Gingival retraction
2. Buccal defect
3. Poor Implant aesthetic (grey)
4. Future potential peri-implantitis
Current alternatives
Hard & Soft tissue augmentation :
Bone grafting for hard tissue and connective tissue grafting for soft tissue/gums. Surgical?
So, what is socket shield?
Rather than removing the entire tooth, a buccal fragment of the tooth is left on purpose, and the implant is placed lingual to it, so the tooth acts as a shield
When tooth is extracted the PDL comes with it, this PDL provides the vascularization for the bone of the buccal cortical plate.
So, by maintaining the buccal tooth fragment, the periodontium is maintained and thus the vascularization of the keratinized gingiva is also maintained
Objectives
Risk Assessment
Case selection
Parameters
Steps
If anytime the buccal shield is mobile, then you must extract and you must do conventional
Note: Removal of apical tip of the socket shield
Important to take a second radiograph after removal of palatal fragment, to confirm no Gutta-Percha or other remains
First PET Consensus, Madrid 2017, that the Socket shield should be cut at crestal level
Complications
