    Immediate Implant Placemen

     

    IMMEDIATE IMPLANT PLACEMENT

    Sulcular and submarginal incision, involving 2 teeth distal to the tooth to be extracted. No vertical incisions are performed.

     

    Soft tissue margin of the tooth to be extracted more apically placed than the homologous natural tooth

     

     

    IMPLANT POSITION 

    VERTICAL: 3 to 4mm from the soft tissue margin (dictated by adjacent teeth)

    BUCCO-LINGUAL: outer surface of the implant 2mm to 3mm palatally to the bone envelope

     

    Suture the graft to the inner surface of the flap, as if it was a marionette suture.

     

    PROCEDURE

    Incision the papillae: split thickness leaving a good amount of connective tissue on the anatomical papillae

     

    After that dissect along the buccal bone full thickness

     

    After the flap is detached from the buccal bone we go again split thickness beyond the mucogingival junction, first periosteal releasing incision is a conventional deep one, then, with the blade parallel to the mucosa and keeping it very superficial, detaching the muscles that are attached to the alveolar mucosa, you can see the blade through the transparency of the mucosa.

     

    ANATOMICAL PAPILLAE DESEPITHELIALIZATION

    First with the blade and then microsurgical scissors

    Zuchelli arta tarde 1, very important from minute 1’20’’

     

    SOFT TISSUE GRAFT

    Should be placed, ideally, 1mm more coronal than the soft tissue margin, sutured to the base of the anatomical papillae - this isn’t a problem on the delayed approach.

    Should include both mesial and distal papillae

    The flap should completely cover the graft

     

     

    Suture the graft to the inner surface of the flap on the immediate implant placement

    Anatomical papillae are more fragile, because they belong to the extracted tooth, so on immediate implant placement we are not suturing the graft to the anatomical papillae, we are suturing the graft to the base of the surgical papillae:

    Base of the surgical papilla (entry at the buccal) - graft - needle back through the inner surface of  the flap - knot

     

    Horizontal mattress suture

     

    This allows a submarginal positioning of the graft and the inner aspect of the surgical papillae will be entirely available to join the outer aspect of the anatomical desepithelialized papillae.

     

    Only the flap will advance maintaining the graft 1mm apical to the soft tissue margin, this will promote papilla growth in thickness at first and then in height (creeping).

     

    Sling suture around adjacent teeth to CAF

    Very important from minute 2’05’’

    Perforate buccal mesial - sling - perforate buccal distal - sling - knot

     

     

     

    Suture of the papillae of the implant site is last:

    2 single sutures one shot perforates buccal and palatal, one at the mesial papilla and the other at the distal papilla.

    The second suture to make the flap advancement sling suture
