Lets know about Kazanjian Technique of Vestibuloplasty
First of all, Deepening of the vestibule without any addition of the bone is termed as “Vestibuloplasty” or “Sulcoplasty” or “sulcus deepening procedure”.Vestibuloplasty is a procedure to increase the depth by uncovering the existing basal bone of the jaws surgically and by repositioning the overlying mucosa, muscle attachments to a lower position in the mandible/ superior position in the maxilla”.Vestibuloplasty can be done in the maxilla or in the mandible or in both the jaws.
Types of vestibuloplasties.

Mandibular techniques are further divided into two categories.
- Those done on the labial side.
- Those done on the lingual side.
Now, lets understand about Kazanjian technique of vestibuloplasty.
- Kazanjian technique is the oldest Techniques.
- Here, uses mucosal flap from the inner aspect of the lower lip to increase the depth of mandibular labial vestibule as shown in the figure A to E.
- It is usually carried out in premolar to premolar region only.
- Raw area is left on the lip side to promote healing by secondary intention.
- Periosteum on the bone is left intact.

Drawback-Severe scarring of lip mucosa that may decreases the flexibility of the lower lip.
Procedure
As shown in figure A to D
(image 2)
- A submucosal dissection is done from inner aspect of the lower lip to the mucogingival junction.
- A supraperiosteal dissection is directed inferiorly to remove muscle and connective tissue attachments to desired vestibular depth.
- The raised mucosal flap is adapted to the depth of the new vestibule and fixed with sutures or a stent.
- Raw area on the lip side is left alone.
