A Double Case: Socket Shield and Pontic Shield Techniques on Aesthetic Zone

Table 1

Partial extraction therapies (PET) and their indications, adapted from Siormpas et al. [7].

PET	Clinical situation(s) indicated
Root submergence	(i) Unrestorable tooth crown or tooth indicated for extraction absence of apical pathology; (ii) Healthy amputated pulp or endodontic therapy completed intention to preserve the alveolar ridge; (ii) Planned removable full or partial prosthesis; (iv) Planned pontic site beneath fixed prosthesis; (v) Cantilever pontic site as an alternative to two adjacent implants; (vi) Actively growing young patient planned for implant treatment later; (vii) Ridge preservation in conjunction with other PET
Socket shield	(i) Unrestorable tooth crown or tooth indicated for extraction tooth root with or without apical pathology; (ii) Intention to preserve the alveolar ridge, specifically to prevent buccopalatal collapse; (iii) Immediate implant placement; (iv) Ridge preservation in conjunction with other PET
Pontic shield	(i) Unrestorable tooth crown or tooth indicated for extraction tooth root with or without apical pathology; (ii) Intention to preserve the alveolar ridge; (iii) Planned pontic site(s) beneath fixed prosthesis; (iv) Cantilever pontic site as an alternative to two adjacent implants; (v) Ridge preservation in conjunction with other PET
Proximal socket shield	(i) Unrestorable tooth crown or tooth indicated for extraction tooth root with or without apical pathology; (ii) Intention to preserve interdental papillae; (iii) Planned immediate implant placement sites of two or more adjacent implants; (iv) Papillae preservation in conjunction with other PET
