i wanna ask some questions about plastic surgery around dental implants :
1) Are there rules or protocols of optimizing the soft tissues buccal to the dental implant is it important whether there is soft tissue defect buccally or not ?
2) How can I estimate that this area need soft tissue augmentation in cases of mild defects ?
3)What is the acceptable width of keratinized tissue around dental implant beyond which the gingiva must be harvested ?
4) Does this width differs in anterior implants from posterior implants ?
5) Finnally, is kertinized or attached ginigiva needed for the long term health of the implant?
Thank you
